Description
Technical field
The present invention relates to a kind of method of constructing floodgate wall, the method for constructing floodgate wall fast under particularly a kind of soft coal opening water gushing out with high pressure condition.
Background technology
At present, under soft seam especially three soft-conditions during digging laneway generation high-pressure high-flow gushing water, the general method that adopts concrete to construct floodgate wall, cement injection reinforced roadway exterior wall, this methods engineering amount is great, operational difficulty, and speed of application is slow, the per pass operation all will be waited for the intensity length of time of concrete and cement paste, after engineering was all finished, floodgate wall can not come into operation at once, must wait for 28 days the intensity length of time of concrete; In addition, concrete, cement paste can produce in consolidation process and shrink, and the permeability of cement paste is bad, and the cementability of cement and coal body is relatively poor, and adhesive strength is also low, and water leakage was big after often floodgate wall built up, even caused the engineering failure.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing drawback of constructing floodgate wall, usefulness cement grouting and reinforcing roadway surrounding rock method with concrete, and provide the method for constructing floodgate wall fast under a kind of soft coal opening water gushing out with high pressure condition, construct the floodgate wall body of wall with Bo Leiyin chemical water shutoff and reinforcement material, roadway surrounding rock is carried out grouting and reinforcing with Bo Leiyin chemical water shutoff and reinforcement material.
The present invention solves the technical scheme that its technical problem takes: the method for constructing floodgate wall fast under this soft coal opening water gushing out with high pressure condition is characterized in that it can be undertaken by following five steps:
A, construct the temporary water dash wall, at first pre-buried aqueduct in the clay bag of then clay being packed into, is built with clay bag vertical transport lane and to be built the temporary water dash wall, and big portion water burst is forced in the aqueduct that places;
B, construct entity temporary water dash wall one, at first build the work stone wall by laying bricks or stones in its front end vertical transport lane, between work stone wall and temporary water dash wall, with the Bo Leiyin that do not foam make bonding agent, building stones are built entity temporary water dash wall by laying bricks or stones one as aggregate, roadway surrounding rock is provided with row's screw-thread steel resin anchor at least before the building wall, the pre-buried Grouting Pipe that goes up is carried out grouting and reinforcing by Grouting Pipe to its roadway surrounding rock behind the building wall in the building wall;
C, construct the filling section, at first build the work stone wall by laying bricks or stones at its front end vertical transport inter-road, between work stone wall and entity temporary water dash wall, use instead the foaming Bo Leiyin make bonding agent, spoil/building stones are built the filling section by laying bricks or stones as aggregate, the pre-buried Grouting Pipe that goes up is built the back by laying bricks or stones and by Grouting Pipe its roadway surrounding rock is carried out grouting and reinforcing in building by laying bricks or stones;
D, construct the main body floodgate wall, at first build the work stone wall by laying bricks or stones at the vertical headentry of its front end, intersegmental at work stone wall and filling, again with the Bo Leiyin that do not foam make bonding agent, building stones are constructed the main body floodgate wall as aggregate, roadway surrounding rock is provided with row's screw-thread steel resin anchor at least before the building wall, the pre-buried Grouting Pipe that goes up is carried out grouting and reinforcing by Grouting Pipe to its roadway surrounding rock behind the building wall in the building wall;
Sprayed mortar is 3～5 meters in e, the outer tunnel of main body floodgate wall, and the grouting and reinforcing hole that is at least a row is set, and uses the hole packer sealing of hole, carries out grouting and reinforcing with Bo Leiyin chemical water shutoff and reinforcement material;
Described temporary water dash wall, entity temporary water dash wall, filling section, the every segment length of main body floodgate wall, press the adhesive strength of Bo Leiyin and aggregate and the adhesive strength and the water burst hydraulic pressure designing and calculating of both sides, tunnel country rock and determine that the adhesive strength of Bo Leiyin and aggregate and both sides, tunnel country rock should be greater than water burst hydraulic pressure.
The method of constructing floodgate wall fast under this soft coal opening water gushing out with high pressure condition provided by the present invention, wall construction needn't carry out the roadway surrounding rock slotting, significantly reduced engineering quantity, improved working security, the floodgate wall that the Bo Leiyin chemical material is constructed fast and the adhesive strength of coal and rock are than the high several times of cement, after body of wall was built several minutes, its compressive strength can reach more than the 50Mpa; In addition, the concreting that this method has been cancelled all body of wall end facing waters and backwater end protects the lane, adopt Bo Leiyin chemical material grouting and reinforcing roadway surrounding rock, its intensity and water-resistance obviously improve, save concrete fully and constructed the curing time of floodgate wall, realized the rapid construction of under soft coal opening inner high voltage water burst condition, constructing floodgate wall.
