Description

Technical Field

[0001] The invention relates to the technical field of concrete construction, in particular to an underwater non-dispersible concrete pouring template. Background Art

[0002] Currently, during bridge and underwater construction, the casting formwork is directly used to achieve the effect of underwater concrete pouring. A waterproof layer is poured in the casting formwork in advance to achieve the effect of non-dispersion underwater after the concrete is poured. The casting formwork consists of a mold and a cover plate. In addition, the casting formwork needs to be constructed with the help of a lifting device, so the connection strength and stability of the mold and the cover plate are very important.

[0003] The current concrete pouring formwork requires a clip to be installed every half meter. The clip lacks a positioning structure after installation, which not only increases the labor during the installation of the clip, but also makes the clip easy to loosen after installation. In addition, the pouring software will shake in the water after installation, causing water seepage at the concrete pouring position. Secondly, the locking bolts of the cover plate are easy to loosen after installation, reducing the reinforcement strength of the cover plate. Summary of the Invention
