Description
Technical field
The utility model belongs to ground technical field of construction, and in particular to a kind of landfill material for being suitable for embedded soil pressure cell
Material and its method for embedding and its burial equipment.
Background technology
In City Subway Station or high-building construction, narrow space, ambient boundary complicated condition is various.Deep basal pit is opened
Dig safe mass, duration and the cost for directly affecting whole engineering.Modern deep basal pit is frequently with ground-connecting-wall, suspended wall campshed, steel plate
The compound gear shield forms such as stake, supporting use deep-mixed pile cut-pff wall, cause periphery to build to prevent undisturbed soil destruction outside foundation pit
Build thing damage and the safe handling of various pipelines.The change of the soil pressure of retaining structure and crater wall interface different depth is engineering project
Risk assessment must survey project with control, generally directly be measured using soil pressure cell.However, severe work on the spot environment makes to bury
If soil pressure cell survival rate it is relatively low, the data distortion measured, confidence level is difficult to ensure that, directly influences the accurate of Monitoring Result
The differentiation and evaluation of property and reliability.To find out its cause, mainly have at 2 points：
When a kind of no effective soil pressure cell method for embedding, at present, the side for the embedded soil lateral pressure box that drills
Method is as follows, drills on soil after wall, the soil pressure cell that then rate is set is put into the hole being drilled, and then uses fine sand
Tamp, this method needs secondary drilling, and fine sand tamps very difficult, and construction cost is higher, and drill can cause it is native around
There is soil arching effect in body, thus cause surrounding soil internal stress redistribution, act on arch after or arch on soil pressure
It is delivered in arch springing and surrounding soil, causes test result inaccurate.
Two are the absence of a kind of material of suitable soil pressure cell landfill, and it is smaller that original soil pressure cell buries hole remaining space, in addition
Mud effect in drilling, make can not directly or pumping backfill fine sand, therefore, it is necessary to improve embedding material property, 1) needs are 1
There are enough pumping flows in writing brush footpath, 2) easy draining, quick gain in strength characteristic are needed, 3) structure cannot be formed
Body, can not intensity it is too low, influence soil pressure cell stress, strength characteristics is preferably close to fine sand, 4) it is cheap.According to investigation, mesh
It is preceding in the former drilling of pressure cell, also nobody used other embedding materials.

Kong Zhong, makes hard long tube lower nozzle deeply to the foot of hole for placing soil pressure cell.Further, the hard long tube is preferably
Steel pipe.
The place of embedded soil pressure cell is being needed to carry out holing with slurry wall protection, and the soil pressure cell and branch that rate is set first
Frame is put into the hole being drilled；Then, the grout outlet of grouting pump is connected into a hard long tube by hose, hard long tube is inserted into
In drilling, make hard long tube lower nozzle that to foot of hole, high concentration slurry deeply is replaced with low concentration mud；Then sand will be irrigated
The grout outlet of stock pump is connected on hard long tube by hose, opens perfusion mortar pump, is started to inject embedding material, is filled in injection
In materials process, hard long tube is gradually lifted, until drilling is filled embedding material.
The advantages of the utility model and have the beneficial effect that：
The embedding material of the utility model, has following advantage, meets the requirement of soil pressure cell embedding material.
1st, there are enough pumping flows in 1 writing brush footpath；
2nd, easy draining, have quick gain in strength characteristic；
3rd, structure is not formed, strength characteristics is close to fine sand；
4th, it is cheap.
The inbuilt method of soil pressure cell is carried out using above-mentioned embedding material and equipment, same hole landfill is realized, improves survey
Test result accuracy, improves the inbuilt efficiency of soil pressure cell.
