Separate pile with hubs voltage

 

(57) Abstract:

The invention relates to the construction, in particular to pile foundations, and approved for installation of foundations on sloping piles. Effect: increased efficiency of production of pile construction, and transportation and warehousing. For pile does not require sophisticated equipment, as disclosure of the elements is provided by the structure. Separate pile with hubs voltage includes reinforced concrete tube of rectangular cross section having triangular grooves on the edge and two side surfaces that act as stress concentrators, and a guide wedge. Inclined piles are made of a single element with an internal cavity filled with an incompressible fluid is water intended for uniform pressure in places of stress concentration. In the immersion process reinforced the trunk is divided into two sloping piles. 4 Il.

The invention relates to the construction, in particular welded to the foundations.

A known construction of a so-called gantry piles, consisting of forming the pile shaft longitudinal branches, which when immersed razdevayutsya to achieve the specified lower technical result when using known construction, is that in the known construction each of the elements are manufactured separately and the spread of the piles when diving due to the formation of a soil wedge allows you to immerse piles only in weak soils.

Also known so-called fan-shaped pile, consisting of two branches villereversure section and a Central element, the joint connecting elements (album "Piles precast, reinforced concrete pyramidal gantry fan. Institute of organization, mechanization and technical aid to construction. Powernetworker, Yaroslavl, 1976, S. 64).

For reasons that impede the achievement of specified following technical result when using the known constructions is that in the known construction each of the elements are manufactured separately, the branches are immersed due to the formation of a soil wedge, and there are complex connections between elements.

The closest design to the same destination to the claimed invention by the combination of features is printed pile with the broadening of the gantry type, which includes the inclined piles and the guide wedge (the hydrographic Anoshkin, C. K. Dudarov. Tower foundations for engineering structures is, impede the achievement of the specified lower technical result when using the known designs adopted for the prototype, is that in the known construction, each inclined pile is produced, transported and immersed separately.

The invention consists in the following.

The use of inclined pile instead of the usual more efficient because it increases the bearing capacity of pile Foundation and better horizontal loads.

The technical result can be expressed in increasing the efficiency of the production of such structures, as well as transportation and warehousing. For pile does not require sophisticated equipment, as disclosure of the elements is provided by the structure.

This technical result in the implementation of the invention is achieved in that in the known construction is divided pile with stress concentrators, which includes reinforced concrete tube of rectangular cross section having triangular grooves on the edge and two side surfaces that act as stress concentrators, and a guide wedge.

The peculiarity lies in the fact that the disorder is what internal cavity for uniform transmission of pressure places stress concentration filled with incompressible liquid is water.

Manufacturer of inclined piles single element increases the efficiency of production, transportation and storage piles, and the use of an incompressible fluid and the presence of internal cavities and grooves eliminates the use of complicated equipment for driving of piles.

Conducted by the applicant's analysis of the prior art, including searching by the patent and scientific and technical information sources, and identify sources that contain information about the equivalents of the claimed invention, has allowed to establish that the applicant had not discovered similar, characterized by signs, identical with all the essential features of the claimed invention. The definition from the list of identified unique prototype, as the most similar in essential features analogue, has identified a set of essential against perceived by the applicant to the technical result of the distinctive features in the claimed device, set forth in the claims.

Therefore, the claimed invention meets the condition of "novelty."The described invention is not based on the change of the quantitative characteristic (s), the submission of such evidence in the relationship, or change its appearance. This refers to the case when the known fact of the influence of each of these features on the technical result, and the new values for these characteristics or their relationship could be obtained from the known dependency relationships.

Therefore, the claimed invention meets the condition of "inventive step".

In the drawings presents:

in Fig. 1 is an external view and a cross-section of the pile;

in Fig. 2 - type piles are installed on the guide wedge;

in Fig. 3 - immersed type is bretania to provide the above technical result are the following.

The design contains a pile 1 of rectangular cross-section with special grooves 2 on the two side surfaces and under the edge. Also in forming the pile is installed metal rod, oval in shape, which is then removed. Formed the core of the inner cavity 3 is filled with water and dived to Golovnin piles installed rubber gasket 4. The full set of each pile is a guide wedge 5.

The operation of the device is as follows. In the immersion process, the pile is installed on the guide wedge when the immersion method is forced closes the cross section of the pile in the internal cavity in places of stress concentration formed by grooves on the surface, two sloping piles 6. To improve the transfer pressure of the internal cavity is filled with an incompressible fluid is water.

The verge of the guide wedge form an angle that creates the angle of inclination of the piles during the dive.

Thus, the above data confirm that the implementation of the use of the claimed device the following cumulative conditions:

The tool embodying the claimed device in its implementation, pridavlennogo device, as it is described in the independent clause sets out the claims, confirmed the possibility of its implementation using the steps described in the application or known before the priority date tools and methods.

The tool embodying the claimed invention in its implementation, is able to achieve perceived by the applicant of the technical result.

Therefore, the claimed invention meets the condition of "industrial applicability".

Separate pile with concentrators of stresses, including reinforced concrete tube of rectangular cross section having triangular grooves on the edge and two side surfaces that act as stress concentrators, and a guide wedge, characterized in that the inclined piles are manufactured as a single element with an internal cavity filled with an incompressible fluid is water intended for uniform transmission of pressure in places of stress concentration.

FIELD: construction engineering.

SUBSTANCE: invention relates to design of piles driven by method of static forcing-in using force-in plants or by method of dynamic forcing-in by means of pile drives. Proposed pile is made in form of prismatic shaft with pyramidal end piece on side faces of which longitudinal slots are made over entire length deepening in direction of end piece. Novelty is that angle of tilting of pyramidal faces of end piece relative to axis of shaft is 30°-45° and longitudinal slots are deepened in direction to end piece to form angle of 10°-24° with axis of shaft. Said slots have form of trapezium in cross section with base located on side face of shaft, and width of slot is 0.3-0.5 of width of side face.

EFFECT: reduced driving-in forces at preservation of high bearing capacity.
