Problems solved by technology

Segment partial or overall floating will directly lead to problems such as segment misalignment, cracks, damage, and even axis deviation. Water hazards and safety hazards will affect the quality of the project
If the difference from the design elevation is too large, various methods must be used to adjust it, which will also increase the project cost and cause waste

Abstract

The invention discloses a segment fixing pile device for fixing a shield tunnel segment, which comprises a grouting outer sleeve and a grouting inner sleeve; the front end of the grouting outer sleeve is provided with a connecting part and a step part, so that The connecting part and the step part are fixedly connected, the rear end of the grouting outer sleeve is provided with a sealing cover; the front end of the grouting inner sleeve is provided with a support part, and the support part is located on the step part, and the step part The grouting inner sleeve is fixedly connected with the supporting part, and the back end of the grouting inner sleeve is connected with a grouting bag; the connecting part and the outer end of the grouting outer sleeve near the connecting part are both provided with threads. The invention also discloses a construction method of the segment fixing pile device, which comprises the steps of opening the grouting hole, stirring the grouting liquid, grouting and the like. The invention can timely fix the tunnel segment during shield construction, thereby effectively improving construction efficiency and construction quality.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling engineering, in particular to a segment fixing pile device for fixing shield tunnel segments and a use method thereof. Background technique [0002] With the rapid development of my country's urban subway construction, the shield method has been widely used for its advantages of high efficiency, safety and environmental protection. However, when the shield machine is constructed under the condition of water-rich stratum, the problem of tunnel segment floating is particularly prominent. The floating of the shield tunnel segment means that the segment is affected by factors such as geology, groundwater, and synchronous slurry after it comes out of the tail shield. Causes the upward displacement of the segments. Segment partial or overall floating will directly lead to problems such as segment misalignment, cracks, damage, and even axis deviation. Come waterproof hidden danger and safety h...
