Abstract

The invention discloses a water passing box culvert on a soft soil foundation and a construction method of the water passing box culvert. The water passing box culvert comprises a box culvert foundation, wherein the box culvert foundation sequentially comprises a reinforced filter net layer, a gravel soil layer, a durable reinforced filter net layer, a graded broken stone layer and a cushion layerfrom bottom to top, and the water passing box culvert is poured on the cushion layer; a body of the water passing box culvert is of a frame structure with a single box and three chambers, the frame with the single box and three chambers forms three water passing channels, a road pavement structure is arranged at the top of the water passing box culvert, a water separation wall is arranged on theupstream of the water passing tank culvert, and a paving layer is arranged on the downstream of the water passing tank culvert; and wing walls are arranged at joints between the water passing tank culvert and both sides of a river channel, and concrete protecting feet are arranged at the ends of each wing wall. The water passing box culvert is stable in foundation structure, not prone to generatequality diseases caused by uneven settlement of the foundation, lower in construction cost and easy to operate a construction technology, and does not need large-scale mechanical equipment for construction.

Description

technical field [0001] The invention belongs to the technical field of water box culvert construction, in particular to a water box culvert on soft ground and a construction method thereof. Background technique [0002] Municipal sewage treatment projects are generally built near the river, so that the treated sewage can be discharged into the nearby river. When the existing municipal road and sewage plant are located on both sides of the river, special structures need to be built to connect the existing municipal road and the access road of the sewage plant. . Generally, bridge projects are built across rivers, such as reinforced concrete bridges such as simply supported girder bridges, continuous girder bridges, arch bridges, cable-stayed bridges, or steel structure bridges such as steel frame bridges. The construction of the foundation, piers, abutments and supports in the substructure is often a difficult part of the entire bridge construction because it is located in t...
