Embodiment Construction

[0022] An underwater concrete pouring process, comprising the following steps:

[0023] 1) Making steel cages on water:

[0024] Reinforcement cage: Reinforcement cages can be made into cubes or cuboids, and after they are made, they are temporarily stacked on a flat place to prevent deformation. The model of the steel bars made of the steel cage is selected according to the shape and size to meet the lifting requirements. The lap joints between the steel bars are bound with iron wires or welded, and the welding should meet the welding standards. The reinforcement cage should be fixed when lifting. If the overall strength of the reinforcement cage is insufficient, it is necessary to set up reinforcement stirrups, or set up a steel structure frame.

[0025] Reinforcement binding: Process the skeleton reinforcement and mesh reinforcement according to the drawings, and then splice the skeleton reinforcement according to the drawings, and weld them firmly according to the specif...

Abstract

The invention discloses an underwater concrete pouring process. The underwater concrete pouring process comprises following steps that firstly, a steel reinforcement cage is made on water, wherein according to the actual needs, framework reinforcing steel bars and mesh reinforcing steel bars are machined, the framework reinforcing steel bars are spliced, according to the standard, welding is form,according to the framework reinforcing steel bars, the mesh reinforcing steel bars are assembled, finally, reinforcing meshes are laid on the inner side, that is the periphery, and the bottom of thesteel reinforcement cage, after the meshes are in lap joint, the meshes and the mesh reinforcing steel bars are bound firmly through fibers, and a whole is formed through the meshes and the mesh reinforcing steel bars; secondly, geotechnical cloth is laid in the steel reinforcement cage, wherein on the geotechnical cloth, at intervals of 10 cm, the geotechnical cloth and the reinforcing meshes areconnected through the fibers, and the geotechnical cloth can be tightly attached to the reinforcing meshes on the inner side of the steel reinforcement cage; thirdly, underwater foundation pit excavation is carried out, and the basic plane is leveled; fourthly, the steel reinforcement cage is lifted and immersed into the foundation pit; and fifthly, concrete pouring is carried out. The underwaterconcrete pouring process is higher in work efficiency, safe and reliable in construction and free of formwork erecting.

Description

technical field [0001] The invention relates to the technical field of concrete pouring, in particular to an underwater concrete pouring process. Background technique [0002] Concrete pouring refers to the process of pouring concrete into the mold until it is plasticized. In civil engineering, concrete and other materials are put into the mold to make a predetermined shape. When pouring concrete, the free height of concrete should not exceed 2m. When it exceeds 3m, it should be Take appropriate measures. [0003] Now there are many concrete projects that need to be carried out under the water surface line, especially the construction of embankment feet or seawall pond feet and underwater concrete construction in other fields. Waterproof measures should be taken, and the formwork should be established in the dry work site, and the concrete should be poured after the form work. [0004] In order to ensure the quality of construction in traditional underwater concrete pourin...
