Embodiment Construction

[0057] Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meanings as commonly understood by those skilled in the art. Before further describing the embodiments of the present invention in detail, some terms for understanding the embodiments of the present invention are defined.

[0058] In the vertical pipe jacking construction, the tunnel includes: a plurality of fixed steel pipe sheets M and a plurality of movable steel pipe sheets Q. That is, a complete tunnel is formed by a plurality of fixed steel pipe sheets M and a plurality of movable steel pipe sheets Q. Wherein, the movable steel pipe sheet Q is set at the ventilation opening or the escape opening, and the fixed steel pipe sheet M is around the movable steel pipe sheet Q. The fixed steel pipe sheet M and the movable steel pipe sheet Q can be fixedly connected by bolts.

[0059] When setting vents and escape openings, it is necessary to disassemble the movab...

Abstract

The invention discloses a construction method of the vertical pipe jacking of an urban underground comprehensive pipe gallery tunnel, and belongs to the technical field of pipe gallery tunnel construction. The method comprises the steps of determining a target jacking area in the urban underground comprehensive pipe gallery tunnel; installing a sealing device around a soil layer of the target jacking area, and improving the grouting of the soil layer of the target jacking area; arranging a pipe jacking machine and a driving support assembly in sequence from top to bottom just below the targetjacking area; controlling the driving support assembly to drive the pipe jacking machine to jack upwards, and arranging a plurality of pipe joints in sequence between the pipe jacking machine and thedriving support assembly in the process until the pipe jacking machine is ejected out of the ground; fixing the plurality of pipe joints so as to form a jacking well; and removing the pipe jacking machine and the driving support assembly so as to complete the construction of the vertical pipe jacking of the urban underground comprehensive pipe gallery tunnel. According to the method, by constructing the underground vertical pipe jacking, the construction efficiency is improved, the construction area is reduced, and potential safety hazards of collapse and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of pipe gallery tunnel construction, in particular to a vertical pipe jacking construction method for urban underground comprehensive pipe gallery tunnels. Background technique [0002] The urban underground comprehensive utility gallery tunnel refers to the comprehensive tunnel space used to set up electricity, communication, gas, heating, drainage and other pipelines underground in the city. During the shield tunneling construction process of the urban underground comprehensive pipe corridor, it is necessary to set up escape openings and ventilation openings. However, limited by the urban environment, some shield tunnels are located in densely populated downtown areas or under streets with concentrated traffic, which affects the setting of escape ports and vents. By adopting the method of vertical pipe jacking and setting vertical escape openings and vents, the impact on the city can be reduced. Therefore...
