Concrete cast-in-place water collecting pit type disassembly-free form device and equipment

Abstract

The invention discloses a concrete cast-in-place water collecting pit type disassembly-free form device and equipment. The concrete cast-in-place water collecting pit type disassembly-free form deviceand equipment comprise a shell, a motor space is formed in the upper side of the shell, an annular sliding groove is formed in the left side of the motor space, the annular sliding groove is an annular space, a hydraulic oil space is formed in the right side of the motor space. The concrete cast-in-place water collecting pit type disassembly-free form device and equipment is a disassembly-free water collecting pit pouring template which can pour a cylindrical water collecting pit, the depth and the cylindrical diameter of the water collecting pit can be set according to the requirements of auser, the pit base part of the water collecting pit is dug out according to a set value, the angle of the form is changed according to the previously set cylindrical diameter, a sealed barrel body similar to a circular surface is constructed through a plurality of forms, the barrel body is placed into a pit dug before, concrete is poured into an interlayer between the barrel body and the pit, thebarrel body can be put away when the concrete is formed, complex form dismantling can be avoided, and cylindrical water collecting pits of various sizes can be manufactured according to needs.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a dismantling-free formwork device and equipment for a concrete cast-in-place sump. Background technique [0002] The sump drainage method, also known as the open drainage method, is to set a sump at the bottom of the pit during the excavation of the foundation pit, and excavate drainage ditches along the periphery or the center of the pit bottom, so that water flows into the sump, and then use The sewage pump (submersible sewage pump) pumps away. The pumped water should be led away from the foundation pit so as not to flow back into the foundation pit. During construction in the rainy season, intercepting ditches or earth embankments should be excavated around the foundation pit or upstream of the ground water to prevent ground water from flowing into the foundation pit. This method is suitable for coarse-grained soil layers, and also for clay layers with small water seepa...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a concrete cast-in-place sump without dismantling formwork device and equipment, which solves the problem that after the concrete is formed, the wooden boards are removed, the dismantling process is complicated, and the poured sump may be damaged.
