Abstract
The utility model provides a strengthen drilling secant pile, includes a plurality of plain stakes and a plurality of meat or fish stakes, a plurality of plain stakes are alternate with a plurality of meat or fish stakes arranges the permutation formula that forms structure, and interlock each other between every two adjacent plain stakes and the meat or fish stake, place a steel reinforcement cage in each meat or fish stake, placed a H shaped steel in each plain stake, compared with the prior art, the utility model discloses set up H shaped steel in plain stake, but effective resistance exposes the pulling force of production because of the excavation, fine solution the problem of the plain stake of concrete because of probably being drawn the feather checking, construction process is simple, level of mechanization is high, has improved load -carrying properties, has guaranteed the security performance of structure.
Description
Technical field
This utility model relates to the Metro Deep Excavation interlocking pile that a kind of geological condition is poor, specifically a kind of reinforcement interlocking pile, belongs to Foundation Pit Support Engineering technical field.
Background technology
Base pit engineering has the strongest individual character and tau-effect, if Design of Retaining Structure or construction wrong, can directly affect the safety of the whole base pit engineerings of surrounding enviroment, even entail dangers to such as surrounding building, underground utilities, municipal works, road.At present, in the area that geological conditions is relatively poor, use more interlocking pile building enclosure be adjacent studs be one meat or fish stake one element stake be mutually twisted, factor stake is not placed steel reinforcement cage, the plain stake that after causing excavation of foundation pit, side exposes produces bigger side force, concrete element stake may be made to produce cracking in various degree, bring potential safety hazard.
Summary of the invention
According to the deficiencies in the prior art, this utility model provides one to strengthen interlocking pile, well solves concrete element stake because tension producing the problem in crack, and construction technology is simple, and mechanization degree is high.
This utility model is realized by techniques below scheme:
A kind of reinforcement hole-drilling interlocking pile, including the stakes of multiple element and multiple meat or fish stake, the stake of the plurality of element is alternate with multiple meat or fish stakes arranges that formation is mutually twisted between entire column type structure, and the most adjacent two plain stakes and meat or fish stake；It is placed with a steel reinforcement cage in each meat or fish stake, in each element stake, is placed with a H profile steel.
Preferably, the central spot of each element stake and each meat or fish stake is on same level line.
Preferably, the stake of described element is identical with the footpath sectional dimension of meat or fish stake.
Preferably, described element stake footpath sectional dimension is 1000mm, and element pile concrete intensity is C20.
Preferably, described meat or fish stake footpath sectional dimension is 1000mm, and meat or fish pile concrete intensity is C30.
Preferably, described H profile steel is equal with the length of steel reinforcement cage.
Preferably, the size of described H profile steel is H850*300.
This utility model beneficial effect:
Compared with prior art, this utility model sets up H profile steel in element stake, it is effective against because excavation exposes the pulling force produced, well solve the problem that concrete element stake produces crack because of possible tension, construction technology is simple, mechanization degree is high, improves load-carrying properties, it is ensured that the security performance of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is hole-drilling interlocking pile meat or fish pile constructing process flow chart；
In figure: 1 element stake, 2 meat or fish stakes, 3 steel reinforcement cages, 4 H profile steel.
Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, this utility model is further described.
Embodiment one:
As shown in Figure 1, a kind of reinforcement hole-drilling interlocking pile, including the stake 1 of multiple element and multiple meat or fish stake 2, arrange alternate with multiple meat or fish stakes 2 of multiple element stake 1 forms entire column type structure, and be mutually twisted between the most adjacent two plain stakes 1 and meat or fish stake 2, the central spot of each element stake 1 and each meat or fish stake 2 is on same level line, element stake 1 is identical with the footpath sectional dimension of meat or fish stake 2, element stake 1 footpath sectional dimension is 1000mm, element stake 1 concrete strength is C20, meat or fish stake 2 footpath sectional dimension is 1000mm, and meat or fish stake 2 concrete strength is C30；Being placed with a steel reinforcement cage 3 in each meat or fish stake 2, be placed with a H profile steel 4 in each element stake 1, H profile steel 4 is equal with the length of steel reinforcement cage 3, and the size of H profile steel 4 is H850*300.
First constructing during construction meat or fish stake 2 of constructing after element stake 1, element stake 1 concrete uses ultra-retardation concrete, it is desirable to must complete the construction of meat or fish stake 2 before element stake 1 concrete initial set；Require to complete the construction of H profile steel 4 before element stake 1 initial set, use full-sleeve to creep into the concrete cutting away adjacent plain stake 1 intersection when meat or fish stake 2 is constructed, it is achieved occlusion, drilling construction order B1---A1---B2---A2---B3---A3.
As in figure 2 it is shown, hole-drilling interlocking pile element stake 1 construction technology process:------------------------grab bucket is fetched earth, and------removing loosened soil checks at the bottom of hole, and---------stake machine shifts measurement concrete elevation---H profile steel lifting is inserted and constructed---concrete perfusion gradually tube drawing casing drilling press-in first segment sleeve pipe check perpendicularity control perpendicularity the centering in place of tube-in-tube pile machine construction interlocking pile top concrete guide wall to put into concreting conduit to measure hole depth to hang installation first segment conduit in measure of pile position setting-out in levelling of the land in preparation of construction.
This utility model sets up H profile steel 4 in element stake 1, it is effective against because excavation exposes the pulling force produced, well solve the problem that concrete element stake produces crack because of possible tension, construction technology is simple, mechanization degree is high, improve load-carrying properties, it is ensured that the security performance of structure, at soft clay area deep basal pit and station, subway station, there is the most wide application prospect.
