Protective pipe plug device for building construction and construction method of protective pipe plug device

Abstract

The invention provides a protective pipe plug device for building construction and a construction method of the protective pipe plug device.The protective pipe plug device comprises a shell and a body, the body is fixedly connected to the inner part of the shell, a clamping mechanism is installed at one end of the body, an outer limiting mechanism is arranged at one end of the shell, through holesare symmetrically formed in the body, and an air valve is fixedly connected to one end of the outer wall of the shell; a pressure gage is fixedly connected to the end, close to the air valve, of theshell, the air valve communicates with one end of the body through the corresponding through hole, sliding grooves are equidistantly formed in one end of the body, limiting claws are slidably connected to the inner walls of the sliding grooves, baffles are fixedly connected to one ends of the limiting claws, and springs sleeve the limiting claws; one ends of the springs are fixedly connected to one side surfaces of the baffles, and the other ends of the springs are fixedly connected to the inner walls of the sliding grooves; and a rotating shaft is rotatably connected to the middle part of thebody through a bearing, and the end, close to the sliding grooves, of the rotating shaft is fixedly connected with a petal wheel. The protective pipe plug device for building construction is simple in structure, convenient to install, stable in structure, more convenient and rapid to use, and high in practicability.

Description

technical field [0001] The invention relates to the technical field of building construction tools, in particular to a protective pipe plugging device for building construction and a construction method thereof. Background technique [0002] In the current water supply and drainage engineering in urban construction, the water supply and drainage pipeline project is a pipe (channel) system project that transports and distributes industrial water supply and domestic drinking water and collects, transports and discharges industrial wastewater, domestic sewage and rainwater. Engineering is an integral part of the water supply and drainage system and plays an important role in the entire water supply and drainage system. It includes the pipe (channel) system itself and various structures on the pipe (channel) system (such as pumping stations, reservoirs , pipe bridges, gate wells, sewage inspection wells, storm water outlets, etc.). Its engineering investment accounts for most o...

Problems solved by technology

[0003] In the existing construction projects, there are mainly two construction techniques for the laying of pipelines. One is the form of open-cut foundation trenches. The trenches are excavated on the ground, and then the pipelines are laid, and finally the soil is compacted. Due to the engineering plastic material The rigidity of the pipe is not as good as that of the steel pipe, so the deformation of the pipe will be formed during the process of pipe compaction, which will affect the realization of the later function of the pipe; the second is the non-excavation process, according to the flexibility characteristics of the plastic pipe, using the tractor drill bit Drilling, like threading a needle, adopts the non-excavation surface method for construction, and the length can reach hundreds of meters. It breaks through other construction methods that must be excavated for pipe materials. However, in the process of non-excavation construction, due to soil The structure is uncontrollable. If it encounters landslide or external force, it is easy to smash the pipe flat. Therefore, we propose a protective pipe plugging device and its construction method for construction.
