Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0036] Such as Figure 1~5 As shown, the present invention provides a temporary sealing device for the shield bearing water receiving portal, which is arranged on the pre-embedded steel ring 3 of the portal of the receiving well, and the shield passes through the temporary sealing device to enter and receive the The receiving shaft of the shield includes:

[0037] A plurality of bases 5, which are evenly distributed on the circumference of the side of the pre-embedded steel ring 3 close to the receiving well;

[0038] Spring steel bundle 6, it comprises one or more spring steel layers, for any one spring steel layer by a plurality of equal-length spring steel plates that are evenly distributed on the plurality of bases 5 along the circumferential direction of the embedded stee...

Abstract

The invention discloses a shield with-water receiving tunnel hole temporary sealing device, which comprises a plurality of bases, a spring steel plate beam and a plurality of press plates, wherein the bases are uniformly distributed on the circumference of an embedded steel ring; the spring steel plate beam comprises one or a plurality of spring steel plate layers; a plurality of spring steel plates form an annular structure; the length of each spring steel plate is smaller than the radius of the embedded steel ring; the press plates are uniformly distributed on the spring steel plate beam and are in opposite arrangement to the plurality of bases; and one end of each press plate is bent at a certain radian in a direction towards a receiving well. The invention also discloses a shield with-water receiving tunnel hole temporary sealing method. The temporary sealing device achieves the goal of blocking the stratum water and soil loss through tightly attaching the spring steel plates onto the shield outer wall and the duct piece outer wall by the self rebounding force. The temporary sealing method solves the problem of tunnel hole sealing implementation difficulty under the with-water receiving condition, and has the advantages that the operation is simple; the labor is reduced; and the efficiency is improved, so that a good tunnel hole temporary sealing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling engineering, and in particular relates to a temporary sealing device and a sealing method for a portal of a shield tunnel with water receiving construction. Background technique [0002] At present, the urban shield tunnel is in the stage of rapid development, the shield construction method is constantly innovating, and the shield receiving method is also continuously improved to reduce the construction risk. Among them, the water receiving method greatly reduces the risk of shield receiving, especially when the stability is poor. , In strata with high water content, the construction method of receiving with water is gradually popularized. The traditional sealing structure of the receiving portal is composed of rubber cord and hinged plate, and the sealing is realized by tightening the wire rope. However, in the case of receiving with water , The rubber cord is difficult to protect, easy ...
