Embodiment Construction

[0036] The following is attached Figure 1-4 The application is described in further detail.

[0037] The embodiment of the present application discloses a pressure-resistant connection structure for secondary split grouting, which is used to connect the grouting pipe 01 and the secondary grouting pipe 02 of the high-pressure grouting machine. figure 1 , including the inner pipe 1, the two ends of the inner pipe 1 are respectively inserted into the grouting pipe 01 and the secondary grouting pipe 02, the inner pipe 1 is provided with two clamping devices 2, and the two clamping devices 2 are respectively clamped on On the outer wall of the grouting pipe 01 and the secondary grouting pipe 02, at the same time, due to the support of the inner pipe 1, the inner pipe 1 and the clamping device 2 cooperate to clamp the grouting pipe 01 and the secondary grouting pipe 02, which improves the internal The firmness of the connection between the pipe 1 and the grouting pipe 01 and the s...

Abstract

The invention relates to the technical field of secondary splitting grouting, in particular to a compression-resistant connecting structure for secondary splitting grouting and a construction method. The compression-resistant connecting structure comprises an inner pipe, a clamping device is arranged on the outer wall of the inner pipe, the clamping device comprises a plurality of clamping claws and a clamping assembly for driving the clamping claws to get close to the inner pipe, the clamping claws are distributed in the circumferential direction of the inner pipe, one end of each clamping claw is hinged to the middle of the inner pipe, the other end of each clamping claw extends towards the end of the inner pipe, a sealing ring is arranged at the end of the inner pipe and arranged on the side wall of the inner pipe in a sleeving mode. The compression-resistant connecting structure for secondary splitting grouting and the construction method have the advantage that the situation that the joint of between a grouting pipe and a grout conveying pipe is prone to breakage due to large pressure is reduced.

Description

technical field [0001] The present application relates to the technical field of secondary split grouting, in particular to a compression-resistant connection structure and construction method of secondary split grouting. Background technique [0002] The second high-pressure splitting grouting method can effectively improve the anchoring force of the prestressed anchor cable. The second high-pressure splitting grouting is carried out when the strength of the cement stone body formed by the first grouting reaches 5.0 MPa, and the grouting pressure is 0.5-1.5 MPa. , up to 2.0Mpa; the grouting time is generally 20 minutes to 1 hour. The secondary grouting pipe is bundled with the steel strand, put together when laying the anchor cable, and directly used in the secondary high-pressure splitting grouting. Because the hole that the lower end of the secondary grouting pipe is opened is large and the lower pressure of the liquid level difference is large, the lower opening is easy...
