Problems solved by technology

[0004] The high cost of temporary support engineering has increased the construction investment of the duct capsule construction project, and the construction organization method of comprehensive excavation will cut off the urban road traffic. Therefore, traffic evacuation and diversion must be carried out during the construction period, which seriously disturbs the residents. travel and normal life, causing urban road traffic chaos

Abstract

The invention discloses a drag reduction method of a mobile support shield for urban utility tunnel construction. The mobile support shield comprises a plurality of shield units arranged in sequence,each shield unit comprises shield walls arranged on two side walls of a utility tunnel pit and shield plates arranged on facades of the shield walls, two adjacent shield units can move relatively in the tunneling direction of the utility tunnel pit, and the shield plates of the two adjacent shield units are always staggered and overlapped in the moving process of the shield units. The drag reduction method comprises the following step: filling positions between the shield plates and the side walls of the corresponding utility tunnel pit with slurry. The utility tunnel pit can be supported without pouring retaining piles.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a method for reducing drag of a mobile support shield used in the construction of urban ducts. Background technique [0002] Pipe capsules refer to public tunnels that are used underground to lay municipal pipelines such as electricity, communications, radio and television, water supply and drainage, heat, and gas. [0003] At present, in the construction of the capsule, it is basically used to pour retaining piles on both sides of the tunnel for temporary support, and under the protection of the retaining piles, the soil in the middle is excavated to form prefabricated and assembled structures or cast-in-place operations. Space for pouring construction of urban duct structures. Calculated at a distance of 3 meters and an average depth of 12 meters, 7,200 meters of wall retaining piles are required per kilometer. Calculated at 1,600 yuan per meter, the cost of temporary s...
