Abstract

An underground shield assembled concrete prefabricated square culvert, characterized in that the first section square culvert (1) is made with a straight opening at one end and an oblique opening at the other end, and the upper half of the square culvert (2) connected with the oblique opening and The lower half of the square culvert (5) is made into a parallelogram U-shaped groove, and the angle between the long side and the short side is α; between the upper half of the square culvert (2) and the lower half of the square culvert (5), the A connecting groove (11) is provided between two adjacent upper half square culvert members (2) and between two adjacent lower half square culvert members (5); in the connecting groove (11), a connecting plate ( 8), stud bolts (10), washers (7) and nuts (9) fix the upper half of the square culvert (2) and the lower half of the square culvert (5); weld the two ends of the connecting plate (8) Connecting plate is arranged to fix reinforcing bar (6). The invention does not need to dig trenches on the ground, which saves the cost of pipe gallery construction and is fast.

Description

technical field [0001] The invention belongs to an underground prefabricated square culvert, in particular to an underground shield-tunnel assembled concrete prefabricated square culvert for roadways produced by a shield tunneling machine in the city's underground. Background technique [0002] At present, the underground construction of cities in many developed countries in the world has adopted advanced and resource-saving technology, which is conducive to creating a harmonious ecological environment and environmental protection, and has solved the phenomenon of repeated trenching and buried pipes and buried cables; The square culvert constitutes the urban underground corridor. In the past, the construction of underground pipe corridors had shortcomings such as large slotting area, large amount of engineering (earthwork), and long construction period. So now the shield machine is used to excavate the roadway for installing square culverts once underground. However, the e...
