Description
Technical field
The present invention relates to the pile detection medium exchange device measuring foundation pile supporting capacity in a kind of building foundation pile driving construction.
Background technology
The load box of the pile bearing capacity test now used, it is at the bottom of foundation pile stake or multiple hydraulic jack is settled in stake stage casing, loads foundation pile.In the program; enter each hydraulic cylinder from ground hydraulic station through an oil inlet pipe injection high pressure liquid force feed and carry out pile bearing capacity detection; separately to bury benefit slurry pipe for causing foundation pile space after detection and carry out benefit slurry; due to section when pile bearing capacity detects and rule useless; mend slurry weak effect, the workmanship of foundation pile can not be guaranteed.
Summary of the invention
In order to overcome above-mentioned defect, the object of the invention is to provide the pile detection medium exchange device that a kind of structure is simple, benefit slurry is effective, Transfer Medium substitutes water or other liquid based on cement paste.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of pile bearing capacity detects Medium Exchange filling device, it comprises rebound, flexible wall, inner cylinder body, outer cylinder body, lower shoe, feed tube, liquid back pipe, this device is arranged on the stage casing of foundation pile, rebound and foundation pile epimere reinforcing cage are welded as a whole, lower shoe and hypomere reinforcing cage are welded as a whole, top offset bar is welded on rebound, and leads directly to earth's surface by protecting pipe; Bottom offset bar is welded on lower shoe, and leads directly to earth's surface by protecting pipe; Centre is an annular pressure chamber, and this pressure chamber is made up of flexible wall, rebound, lower shoe, and flexible wall flange is arranged on rebound, lower shoe; The feed tube of pressure chamber is connected with ground loading system, and liquid back pipe leads directly to earth's surface.
Above-mentioned loading system is oil pump or water pump.
The invention has the beneficial effects as follows:
1. the present invention adopts annular pressure chamber, and lifting surface area is large, and flexible wall and rebound, lower shoe adopt Flange joint, good airproof performance, connects reliable, and does not need separately to fill sealing ring.
2. the medium of the present invention's employing is based on water, cement paste and other liquid, low price, and pollution-free.
3. the present invention adopts interior outer cylinder body to bear pressure, the frame mode that the upper-lower section reinforcing cage of rebound, lower shoe and foundation pile is welding as one, and structure is simple, and the process-cycle is short, easy for installation.
4. the present invention adopts feed tube to inject high-intensity cement paste, and liquid back pipe discharges the method for former medium and air, mends slurry reliable, guarantees the workmanship of foundation pile.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of depression angle of the present invention;
Fig. 3 is the structural representation of cross section of the present invention angle.
Detailed description of the invention
The present invention is described in detail for lower denomination accompanying drawing 1,2,3:
A kind of pile bearing capacity detects Medium Exchange filling device, it comprises rebound 7, flexible wall 6, inner cylinder body 10, outer cylinder body 4, lower shoe 5, feed tube 2, liquid back pipe 9, this device is arranged on the stage casing of foundation pile, rebound 7 and foundation pile epimere reinforcing cage are welded as a whole, lower shoe 5 and hypomere reinforcing cage are welded as a whole, top offset bar 1 is welded on rebound 7, and leads directly to earth's surface by protecting pipe; Bottom offset bar 8 is welded on lower shoe 5, and leads directly to earth's surface by protecting pipe; Centre is an annular pressure chamber, and this pressure chamber is made up of flexible wall 6, rebound 7, lower shoe 5, and flexible wall 6 flange 3 is arranged on rebound 7, lower shoe 5; The feed tube 2 of pressure chamber is connected with ground loading system, and liquid back pipe 9 leads directly to earth's surface.
Above-mentioned loading system is oil pump or water pump.
Displacement bar is for after measuring foundation pile bearing load, and whether qualified the plunger panel of side seal type load box and the displacement of lower shoe, the namely displacement of foundation pile, carry out judgement basis pile bearing capacity according to the displacement of foundation pile.
Liquid back pipe is for completing the slurry of the benefit after loading process, and injected from feed tube by cement paste, liquid medium is discharged from liquid back pipe; when there being cement paste to discharge from liquid back pipe; close liquid back pipe pressurize, now guarantee that foundation pile hypomere cavity fills cement paste, guarantee the workmanship of foundation pile.
