(57) Abstract:Use: irrigation, mainly in irrigation and drainage technique for laying and cleaning of cavities with different cross-sections due to mechanical and hydraulic effects, in particular the municipal and industrial sector. The inventive inside energoneseju sleeve of the working body skipped feed hose attached to the fore end of the punch. The latter is equipped with a damping device, made of a perforated plate and having a locking device for the regulation of its diameter. 1 C.p. f-crystals, 3 ill. The invention relates to the reclamation, mainly for irrigation and drainage equipment used for installation and cleaning of cavities of different sections by mechanical and hydraulic effects, and can be used in the construction industry and utilities.Known denopamine installation with flush hydro jet head, creating a high-speed jet of water, of which the Central jet washes out the recess for the passage of the head in the cavity of the pipe, and the side wash remaining on the walls of the sediments and create jet thrust (Melioratist cannot clean the walls of the drainage pipe from a solid chemical deposits, for example ferrous compounds (process sogrevaniya drains).Known working body chromogranine machine, consisting of a cylindrical body with a tapered front, which is equipped with a damping device made in the form of a hollow spherical surface formed adjacent plates (ed. St. N 1224379, CL E 02 B 11/02, E 02 B 5/10, N 14, 1986). When moving this working body in heterogeneous soils damping device provides uniform sealing of the walls of the formed cavities.The disadvantage of the working body is the fact that the diameter of the damper varies depending on the density of the soil (in denser soils damper is compressed, less dense relaxes and does not have a locking device that allows you to change its cross-section to the desired. For example, when cleaning drainage pipes of different diameters, where for normal operation and reduce the tractive effort necessary to set the diameter of the damper on the inner diameter drains. In addition, the disadvantage of the working body is the absence of punched holes on the plates of the damper, which reduces the quality of cleaning of drains and creates an obstacle for the removal of sediments outside working orgasam, inside of which is placed a flexible element .The disadvantage of installation is that in heavy soils with low moisture content is significantly reduced performance. In addition, when working in heterogeneous soils, for example with variable density and humidity, reduces the quality of underground cavities.The aim of the invention is to enhance the functionality, productivity and quality of work.This is achieved by the fact that in gerontoprotective installation for the device and cleaning of the cavities, including the working body, the punch associated with energoresursiem sleeve, inside which is placed a flexible element, a punch in the nose is made with holes, into which, through the supply hose, missed inside energoneseju sleeves, comes under the pressure of the working medium, for example water. Plate damping devices mounted on the body of the punch, made with holes in the form of perforations, and the damper is provided with a locking device that allows you to adjust its diameter (cross-section).Comparative analysis with the prototype shows that the proposed working body (punch) "Cobra" differs, Thu is a, when this punch is equipped with a damping device made in the form of perforated plates, and has a locking device for the regulation of its diameter. Thus, the proposed work body complies with the criteria of the invention of "novelty."The comparison of the proposed solutions with other technical solutions shows that the use of jet nozzles and the damping device in the form of plates, forming a spherical surface, it is known (see, for example, the above analogues). However, their introduction in the specified communication with other structural elements in the claimed authority "Cobra" and the execution of the damping plates perforated device, allows the device to show new properties, resulting in increased productivity and quality of work. In particular, the perforation allows you to skip roiled silt particles outside of the working body and purify the solid deposits from the inner pipe wall. In addition, a fixed adjustment of the diameter of the damper allows to achieve the universality of the working body, because without changing the cross-section of the punch, you can clean pipes of various diameters. This allows to make a conclusion on compliance-is of Fig. 2 is a longitudinal section through the axis of the working body; Fig. 3 - working body in the work at clearing drains.The working body for the device and cleaning cavities Cobra includes a punch consisting of a cylindrical hollow body 1 with a tapered nose part 2, made in the form of a nozzle with a Central 3 and side 4 holes. The punch connected with energoresursiem sleeve 5, inside of which is omitted feed hose 6 and the flexible element 7. On the cylindrical housing 1 is attached to the damper 8 made of elastic plates 9 with the holes 10 in the form of perforations. The end part of the cylindrical housing 1 is made with a thread on which is screwed an adjusting nut 11 and a latch 12, allowing you to modify the cross section of the damper 8. The end part of the plate 9 of the damper is attached to the guide tube of the damper 13 mounted on the adjusting sleeve 11, with the possibility of free movement by the latter in the direction opposite from the latch 12 (and up) directions. To effect the adjustment of the cross section of the damper on the adjustment sleeve 11 has openings 14.1. Work punch "Cobra" in the jacking holes in the soil is as follows.First, in this case it is not necessary perforative section of the damper and carry out the necessary cross section of the damper and seal cavities in accordance with the description in the source . Through the feed hose 6 to the holes 3 and 4 under pressure is supplied, the working environment, for example water, which wets the cavity and provides a faster transfer punch in the ground.2. Work punch "Cobra" in the cleaning mode of drainage pipes.In Fig. 2 illustrates the operation of a punch in the specified mode. Here before you begin using the control sleeve 11 is set to the diameter of the damper 8 to the inner diameter of the drain pipe 15. The punch sent into the hole of the pipe, in energoresursi sleeve 5 and the feed hose 6 is supplied under pressure working environment, which results in the movement of the punch. While aimed jet of water through the Central and side vents 3 and 4 provide erosion of loose sediments and provide additional traction to the punch, and the damping device 8 through perforated plates 9 provides a scraping from the walls drains 15 dense chemical compounds 16. The last turbulent flow of water washed off and carried away through the holes 10 outside of the punch.The use of the working body - punch "Cobra" in land reclamation, construction and utilities can significantly peete from siltation and chemical sediments. 1.
