The invention relates to the construction of underground structures, namely, to designs of sewage and other wells with manholes, in particular those located on the roadway and pavements, especially to the problems of rehabilitation of the deformed (acting or failing) hatches wells of underground communications.
Currently covering of roads was out the desired quality level. And their background, very feels the lack of uniformity of the surface of the sewer and other hatches relatively the road. Obviously it is very difficult to deduce surface hatch in the construction of a well on the correct. And the main thing, not the fact that builders will bring the pavement exactly on the mark. The difference between the surfaces of even one centimeter palpable for passenger cars. Yes and operation of road coating drawdown or pavement relatively well, or Vice versa. To date, all hatches are regulated in the process of installation by issuing the surface of the hatch to the correct height and base concreted up. And if you need to change the height of the surface hatch the hatch hollowed out, is correct and poured. This requires significant expenses, and often a repaired site of the roadway around the hatch sags, and again is an irregularity.
Known manhole hatch road surface repair use temporary formwork for walls of which stack mixture to restore its height (see RF patent №94032803, E02D 29/12, 1994). This design provides for laying rapidly hardening of a solution on the well ring using temporary formwork for increase in its height. The result is not very strong and expensive facility, which requires restoration of the few times per season.
Known Luc manhole, including a housing with cover and additional repair box (see A.S. SU # 735707, cl. E02D 29/14, 1977). In the famous hatch additional repair box can be used to increase the height of the well as necessary during construction or repair.
This method of increasing the height of the well is labor-intensive, material-intensive and costly, with analysis of a road covering.
Known manhole, including fixed housing and installed with the possibility of moving on the altitude of the head with a cover of the hatch, in which the head in the upper part is made with reference ledge on the perimeter, the bottom surface is broken configuration (see RF patent №2202682, E02D 29/12, 2004). This design to increase the height of less labour intensive, but not sufficiently reliable, since the lifting of the stack without bending is a technically complex task which requires time and effort fixing it raised to full fastening after hardening of a road covering, on which the head rests.
Known Luc manhole, including housing, housed inside the annular element of the well with possibility of vertical travel with regard to him and made with reference plane in its top articulated attached to it cover with a locking device (see the patent of Russian Federation №43277, E02D 29/12, 2004).
Known device has the design of the hatch with hinged lid and locking device, but, like the last, is not very adapted to increase the height of lifting body without distortions also technically difficult and requires time and effort fixing it raised to full fastening after hardening of a road covering, on which housing is based, and the case has a complex structure in respect of the performance of the reference planes.
The closest to the technical nature of the claimed Luc manhole described in the patent of Russian Federation №73887 the class. E02D 29/12, Z. 01.02.2007, publ. 10.06.2008 chosen as a prototype.
Known Luc manhole, including housing, housed inside the well with possibility of vertical travel with regard to him and made with reference plane in its top articulated attached to it cover with a locking device, differs in that the mechanism of vertical movement is in the form of threaded connection, the well is made with thread on the inner surface and the body is made with a thread at the exterior surface of the step that matches the thread pitch of the well, and height thread of a well is at least equal to the height of the housing, the bearing surface performed ring, equipped with diametrically opposed to the samples, and on the opposite side from the axis of fastening of the cover it is fixed a swivel pin plate and the cover is provided with a shut-off device, made in the form of oval holes with circular groove interacting with plate pin.
The housing can be made multi-step and is equipped with at least an additional intermediate coupling, roaming by means of threaded connection, in this interim tube is threaded on the outer surface of the step that matches the thread pitch of the well, and thread on the inner surface coinciding with the thread pitch of the case, the height, the internal thread of the intermediate pipe performed, at least equal to the height of the body.
The disadvantage of the hatch is the complexity of its production, due to the need to make the thread of the big diameter on the inner surface of the ring, the well and the outer surface of the hull of the hatch. And threaded connection of such diameter key, not , especially if it bitumen, covered with corrosion or receive in the time of laying asphalt.
In addition, the operational capabilities of the famous hatch limited because there is no possibility to adjust the slope of the hatch.
The task is to simplify the design of the hatch and its adjustment mechanism, the expansion of its operational capabilities.
The problem is solved by the fact that in the hatch of the well-regulated in the process of operation for height and angle, including a housing placed inside the well equipped with the mechanism of vertical movement of the shell relatively well and executed with the support ring surface in its top for the cover with a locking device ACCORDING to the INVENTION, building the hatch is placed inside the annular element of the well fixed on the site slabs of a well, and made also with a ring bearing surface in the lower its part, with the top and bottom anchor ring surfaces of the body are made located on a circle against each other coaxial holes for placing in the bottom of them fasteners with thread with the possibility of regulating their vertical position through corresponding holes in the upper ring of the bearing surface, which together form a mechanism of vertical movement of the shell relatively well.
Placement of housing hatch inside the annular element of the well, motionless assigned to on-site slabs well, when you run the housing sunroof with the bottom of the ring surface and in the presence of top and bottom anchor ring surfaces located on a circle against each other coaxial holes in conjunction with the placement of the lower holes for fasteners with thread gives the possibility to adjust their vertical position through corresponding holes in the upper reference the ring surface, thus providing lifting and lowering of the housing hatch and its angle relative to the well and the level of the road.
The technical result - to ensure adjust the position of the body hatch for height and angle during operation, which allows you to quickly configure the surface hatch flush with the road indiscriminately pavement.
The proposed Luc has novelty in comparison with the prototype, differing from it in such essential features as the placement of housing hatch inside the annular element of the well fixed on the site slabs well, the housing sunroof and with a ring bearing surface of the bottom in the top and bottom anchor ring surfaces of the body located on a circle against each other coaxial holes for placing in the bottom of them fasteners with thread with the possibility of regulating their vertical position through corresponding holes in the upper ring of the bearing surface, forming together mechanism of vertical movement of the shell relatively well, ensuring the achievement of a given result.
The applicant unknown solutions having the distinctive features, altogether providing achievement of a given result, so he believes that the proposed solution meets the criterion of «inventive step».
The proposed Luc well, providing easy-to regulation surface hatch relatively pavement indiscriminately from asphalt bed, find a wide application in the field of construction of underground structures, namely in the construction of sewage and other wells with manholes, in particular those located on the roadway, on the sidewalks, and other venues, and therefore meets the criterion of «industrial applicability». The invention is illustrated by drawings, where presented at:
- figure 1 - type of hatch on the side in a section;
- figure 2 - view of the hatch from above with partially the cover removed.
The adjustable height and tilt sunroof well contains housed inside the annular element 1 well, fixed at the site slabs well (not shown), case 2, is made with a support ring surface of 3 in their top and with a ring bearing surface of 4 at the bottom of its parts. The ring element 1 is made, in particular, concrete, put on the cement on the site slabs and has a height of slightly less than the height of the building 2. In flat top and bottom anchor ring surfaces 3 and 4 of the housing 2 made located on a circle against each other coaxial holes 5 1 -5 n and 6 1 -6 n , where n is an integer. In the holes 6 bottom of the ring of the bearing surface 6 has the fastening elements 7 with carvings, such as the bolts (or the screws), fixed in the holes with nuts 8 preventing spontaneous rotation bolts 7. The bolts have a diameter of 7, in particular, 16-24 mm. Above the hatch closed cover 9 with a locking device 10 (not shown).
The operation of the proposed hatch is as follows. At repair of asphalt and similar coverings of roads and sidewalks, when there is a need to raise the level of the hatches wells open the locking device 10 and 9 lift the cover of the hatch. To adjust the position of the hatch via through holes in the top 5 of the support ring surface of the 3 bolts 7 screw it deeper (lower) or turn out (up), for example, using the Allen key, changing the vertical position of body 2 in height (for the installation of all the screws 7 in the same height position) and tilt (by installing bolts 7 at different height position) regarding the annular element 1 of the well. The locknuts 8 prevent spontaneous rotation bolts. Equal to the height bolts 7 is ensured by the fact that initially put at the same height bolts, located in the ends of the perpendicular diameters of the circumference to the lower supporting ring surface 4, and then put at the same height and the other bolts 7.
Concrete ring element 1, which is slightly below housing 2 hatch, planted on a cement directly on the floor slabs well and so when lifting or lowering housing 2 hatch remains stationary. He gives the sand or gravel to Wake up with a roadway in the well at a time when housing 2 hatch has been lifted, and does not give asphalt coating adhere to the chassis 2 hatch on all surface. A slight gap between the inner surface of the concrete ring item 1 and outer surface of the housing 2 hatch allows you to adjust in the small slope of the roof adjusting the surface of the cap 9 hatch in compliance with the road.
The proposed Luke gives the opportunity during operation or at the moment of asphalt customized surface hatch to the surface of the roadway with an accuracy of a few millimeters within the height adjustment screws to 70 millimetres.
In comparison with the prototype of the claimed design is more easy to manufacture and has more versatile.
Luc well, adjustable during operation for height and angle, including housing, housed inside the well equipped with the mechanism of vertical movement of the shell relatively well and made with a support ring surface in its top lid placement with a locking device, wherein the building the hatch is placed inside the annular element of the well fixed on the site slabs of a well, and made also with a ring bearing surface in the lower its part, with the top and bottom anchor ring surfaces of the body are made located on a circle against each other coaxial holes for placing in the bottom of them fasteners with thread with the possibility of regulating their vertical position through the corresponding holes in the upper ring of the bearing surface, forming together the mechanism of vertical displacement of housing relative to the ring element of a well.
