Embodiment Construction

[0033] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a quick grouting device, a flange 4 is fixedly installed on the pre-buried orifice pipe 6, the grout inlet pipe 1 passes through the gland plate 3 and is fixedly connected with the gland plate 3, the flange plate 4 and the gland The plates 3 are connected by bolts 10, the grout return pipe 2 is fixedly installed on the gland plate 3, and the polyethylene thin-walled grout pipe 8 communicates with the grout feed pipe 1 through the grout pipe interface snap ring 5;

[0034] The polyethylene thin-walled grouting pipe 8 is a strip-shaped pipe body with both sides folded inward symmetrically, and the shape of the slurry outlet 12 of the polyethylene thin-walled grouting pipe 8 is a double "V" shape.

[0035] A rubber pad 9 is provided between the flange plate 4 and the gland plate 3 .

[0036] The polyethylene thin-walled grouting pipe 8 has a wall thickness of 0.5-1 mm and a raised diameter of 3-5 cm.

Abstract

The invention provides a quick grouting device. A flange plate is fixedly mounted on an embedded orifice pipe; a grout return pipe is fixedly mounted on a gland plate; a polyethylene thin-wall grout injection pipe is communicated with a grout inlet pipe by use of a grout injection pipe connection snap ring; the polyethylene thin-wall grout injection pipe is a strip-like pipe of which the two sides are symmetrically folded inwards; the grout outlet of the polyethylene thin-wall grout injection pipe is double-V-shaped. A grouting method by use of the quick grouting device comprises the steps of 1) welding the flange plate, 2) forming a grouting hole, 3) drooping the polyethylene thin-wall grout injection pipe, 4) fastening the gland plate and the flange plate, 5) mounting a high-pressure pipe, 6) beginning frost boiling operation at the bottom of the grouting hole, 7) flushing the grout inlet and outlet pipelines, and 8) taking out and recovering the polyethylene thin-wall grout injection pipe. The quick grouting device and the grouting method thereof have the advantages that the disadvantages of the orifice-closed grouting method in the existing drilling grouting construction process can be overcome and the construction problem that drilling pipe casting accidents are easy to happen in the grouting hole.

Description

technical field [0001] The invention relates to the field of drilling grouting, in particular to a quick grouting device and a grouting method for foundation anti-seepage treatment engineering. Background technique [0002] With the continuous deepening of socialization construction, the development of various water conservancy projects will inevitably face the foundation treatment of different geological conditions. The orifice sealer grouting method is the most widely used curtain grouting method in the current hydropower industry in my country. At present, during the grouting process, due to cement precipitation and adhesion on the drill pipe, the cement solidifies the drill pipe, resulting in frequent accidents in the hole where the drill pipe cannot be pulled out normally. Especially in strata with broken lithology, extremely developed joints and fissures, and rock formations dominated by fine fissures, the high incidence of pipe casting accidents in holes is still an ...
