Problems solved by technology

When the river is wide and the water flow is not urgent, the bagged soil is generally used to fill from one side to the other along the excavator to form a cofferdam, but this method has the situation that the river water leaks from the cofferdam to the foundation pit The anti-scouring and flood control ability of rainwater in flood season is poor, which is easy to cause collapse

Embodiment Construction

[0022] For a better understanding of the present invention, the following examples are further descriptions of the present invention, but the content of the present invention is not limited to the following examples.

[0023] In view of the prior art, the diversion channel is generally filled with sandbags, which is likely to cause the leakage and collapse of the river water to the foundation pit, such as figure 1 , figure 2 , image 3 as well as Figure 4 As shown together, the present invention provides a prefabricated slab for diversion channel construction, including a prefabricated slab body. Both sides of the prefabricated slab body are provided with grooves 100 along the length direction of the prefabricated slab body, and a locking block 101 matching the groove 100 is formed between the groove 100 and the corresponding side surface of the prefabricated slab body. Take two prefabricated panel bodies, buckle upside down the clamping plate 101 on one side of one prefa...

Abstract

The invention relates to a precast slab for diversion canal construction. The precast slab comprises precast slab bodies, grooves are formed in the two sides of each precast slab body in the length direction of the precast slab body, and clamping plates matched with the grooves are formed between the grooves and the corresponding side faces on the precast slab bodies; and the two precast slab bodies are taken, the clamping plate on one side of one of the precast slab bodies is inversely buckled in the groove in the other side of the other precast slab body, and the two precast slab bodies arefixedly connected. The precast slab is laid at the bottom of a diversion canal and on the dike side so that river canal water can be prevented from seeping from a cofferdam towards the bottom of a foundation pit, the ability of the diversion canal to resist water flow impact can be further greatly improved, the diversion canal is prevented from collapsing, the safety problem of foundation pit construction can be solved to a certain extent, in addition, the precast slab is low in cost, convenient to construct and easy to dismantle, and can be reused in a turnover mode.

Description

technical field [0001] The invention relates to the technical field of construction of an underground comprehensive pipe gallery across rivers and canals, in particular to a method of constructing a diversion channel by using prefabricated panels at a position across a river and canal. Background technique [0002] In recent years, with the development of the construction industry, the utilization rate of underground space is constantly increasing. As a new project that benefits the people, the comprehensive pipe gallery has become a symbol of modern urban development. It avoids the urban disadvantages of dense aerial wiring, pipeline relocation, and repeated excavation of the road surface, and realizes the centralized management and maintenance of urban pipelines. Maintenance has made great contributions to building a modern and civilized city. [0003] During the construction of the urban underground integrated utility tunnel, various unfavorable construction environments...
