Abstract
The utility model relates to a kind of novel water qi of chong channel ascending adversely and lifts auxiliary static pressure pile-sinking bath equipment, it is to be linked to each other respectively with qi of chong channel ascending adversely pipe, centrifugal pump and jet water spout by air compressor, and form in the through hole of access preformed pile, its improvements are, also are connected to escape pipe in through hole.Advantage of the present utility model is: owing to increased escape pipe, make that the pressure in the work progress can be controlled fully, avoid causing the reduction of construction quality and the generation of contingency because of pressure control is untimely, guarantee the safety of construction.
Description
Technical field
The utility model relates to Foundation Design, especially belongs to the auxiliary static pressure pile-sinking bath of water qi of chong channel ascending adversely act equipment in the foundation construction process.
Background technology
In current industrial, in the civilian construction, prestressed high-strength concrete pile is widely adopted, for solving the static pressure construction prestressed high-strength concrete pile in the obvious weakness that exists aspect the geology applicability, people have invented the water qi of chong channel ascending adversely and have lifted auxiliary pile sinking technology, related data is found " pile foundation engineering handbook P478-480 8.6.2 " bath auxiliary pile sinking " by retrieval, interior towards interior row's method and P563-565 10.5 " auxiliary pile sinking method waterborne " 10.5.2, water is interior towards interior row's method (China Construction Industry Press's September nineteen ninety-five) towards auxiliary pile sinking method (two), and the patent No. is 02278050.5,200410061106.9 patent application all auxiliary pile sinking is lifted in the water qi of chong channel ascending adversely and has been done introduction, but the solution of gaslift sandstone soil lift control problem in above-mentioned file, all lacking work progress.
Summary of the invention
The purpose of this utility model is by increasing controllable escape pipe, to reach the purpose of control gaslift lift.
Technical solution adopted in the utility model is: it is to be linked to each other respectively with qi of chong channel ascending adversely pipe, centrifugal pump and jet water spout by air compressor, and forms in the through hole of access preformed pile, and its improvements are, also are connected to escape pipe in through hole.
Advantage of the present utility model is: 1, owing to increased escape pipe, make the pressure in the work progress to control fully, avoid because of the untimely reduction that causes construction quality of pressure control, promptly pressure excessively washes away too greatly or the too low problem that can't wash away and sandstone are discharged of pressure; 2, owing to increased escape pipe and valve, therefore, exhaust is in time avoided the generation of the contingency that a machine beats to reduce pressure when excessively washing away, and guarantees the intact of the safety of constructing and equipment.

Wherein: 1, air compressor 2, qi of chong channel ascending adversely pipe 3, centrifugal pump 4, jet water spout 5, escape pipe 6, valve 7, preformed pile 8, through hole
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further set forth, be illustrated in figure 1 as schematic diagram of the present utility model, it is to be linked to each other respectively with qi of chong channel ascending adversely pipe 2, centrifugal pump 3 and jet water spout 4 by air compressor 1, and in the through hole 8 with qi of chong channel ascending adversely pipe 2 and jet water spout 4 access preformed piles 7, also escape pipe 5 is inserted in the through hole 8 simultaneously, in the utility model, also can be connected to valve 6 on the escape pipe 5.
Operating principle of the present utility model is: work progress mesohigh water, high pressure gas are directly injected stake end sand layer or boulder bed through jet water spout 4 and qi of chong channel ascending adversely pipe 2 by the through hole on the preformed pile 78, utilize the slag effect of taking of backwater, return-air, take away sand, the cobble of an end parts.But in concrete use,, because the pressure of water, gas is too big, cause excessively washing away of sand layer or boulder bed sometimes owing to the structure difference of sand layer or boulder bed, cause hollowization on basis, influence construction quality, can make beating of pile forming machine when serious, produce serious consequence.In the case, in through hole 8, insert escape pipe 5, and by valve 6 on the escape pipe 5 open and close the pressure of controlling backwater, return-air, to guarantee construction quality.
Claims (2)
1, auxiliary static pressure pile-sinking bath equipment is lifted in a kind of novel water qi of chong channel ascending adversely, it is to be linked to each other respectively with qi of chong channel ascending adversely pipe (2), centrifugal pump (3) and jet water spout (4) by air compressor (1), and form in the through hole (8) of access preformed pile (7), it is characterized in that: in through hole (8), also be connected to escape pipe (5).
