Abstract
The high-pressure rotary jet grouting pile with decompression function reinforces water sealing structure, includes row's high-pressure rotary jet grouting pile and row's relief hole；Wherein high-pressure rotary jet grouting pile is distributed in outside margin of foundation pit；Described relief hole is disposed on the outside of high-pressure rotary jet grouting pile.This utility model solves the pressure that traditional injection slurry is diffused into beyond reinforcing scope, high-pressure rotary-spray is unnecessary to be difficult to release, causes the technical problem of ground soil deformation.
Description
Technical field
This utility model relates to a kind of rotary churning pile and reinforces water sealing structure, and especially a kind of high-pressure rotary jet grouting pile reinforces sealing knot
Structure.
Background technology
At present, in Foundation Pit Construction, conventional soil stabilization structure and gap water sealing structure are high-pressure rotary jet grouting pile.High
It is fast that pressure rotary-spraying stake not only has speed of application, and construction machinery is small and exquisite, the advantage that flexibility ratio is big, and high-pressure rotary jet grouting pile utilizes cement
The slurry stagnant water effect to soil stabilization, to waterproof weak spot is the most more significant.It is by high pressure yet with Construction of High Pressure Jet Grouting Pile
Completing the perfusion of serosity, in work progress, conventional high-pressure rotary churning pile is under the effect of high pressure, and serosity flows to and scope is difficult to control
System, thus will result in cement mortar and flow to beyond reinforcing scope, affect next work surface and cause waste of material.Furthermore due to
Under the effect of high pressure, often can cause land upheaval, periphery existing building time serious, will be jeopardized.
Utility model content
The purpose of this utility model is to provide a kind of high-pressure rotary jet grouting pile with decompression function and reinforces water sealing structure, solve
The pressure that traditional injection slurry is diffused into beyond reinforcing scope, high-pressure rotary-spray is unnecessary is difficult to release, causes ground soil deformation
Technical problem.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of high-pressure rotary jet grouting pile with decompression function reinforces water sealing structure, it is characterised in that: include row's high pressure rotation
Spray stake and row's relief hole；Wherein high-pressure rotary jet grouting pile is distributed in outside margin of foundation pit；Described relief hole is disposed on high pressure
The outside of rotary churning pile.
Preferably, the stake footpath of described high-pressure rotary jet grouting pile is 600mm～1000mm.
Preferably, the center of adjacent two high-pressure rotary jet grouting piles is at a distance of 350mm～800mm.
Preferably, the outside of every high-pressure rotary jet grouting pile is all correspondingly provided with a relief hole.
Preferably, described relief hole is tangent with high-pressure rotary jet grouting pile.
Preferably, the aperture of described relief hole is 100mm～150mm.
Compared with prior art this utility model has the characteristics that and beneficial effect:
1, this utility model solves the pressure difficulty that traditional injection slurry is diffused into beyond reinforcing scope, high-pressure rotary-spray is unnecessary
To discharge, to cause the technical problem of ground soil deformation.
2, this utility model utilizes the complement one row pressure power release outside original design high-pressure rotary jet grouting pile footpath of high-pressure rotary-spray rig
Hole, thus reach pressure release effect, simultaneously work as the effect of fixing range of grouting.
3, this utility model utilizes high-pressure rotary-spray rig to bore relief hole in advance at rotary churning pile reinforcing scope boundary, thus reaches
To the effect of pressure release, flowing to the serosity beyond reinforcing scope can flow out from relief hole, and the most unnecessary pressure can be released,
Thus prevent uplift of soil from deforming.
4, this utility model can reduce or eliminate the Construction of High Pressure Jet Grouting Pile impact on surrounding building, it is to avoid churning
Stake injection slurry is diffused into beyond reinforcing scope, impacts for subsequent construction, it is to avoid the significantly deformation of the soil body, to will construct
Interval plays a protective role.
