Description
Technical Field
The invention belongs to the field of corrugated pipe construction, and particularly relates to a PE double-wall corrugated pipe orifice plugging device.
Background
The PE double-wall corrugated pipe has the characteristics of light weight, high pressure resistance, good toughness, quick construction, long service life and the like, has the characteristics of good corrosion resistance, high insulativity, smooth inner wall, small flow resistance and the like of a common plastic pipe, and also has the characteristics of excellent ring rigidity, good strength and toughness, light weight, strong impact resistance, difficult damage and the like due to the adoption of a special hollow annular structure. The double-wall corrugated pipe is widely applied to the fields of municipal drainage and pollution discharge, agricultural irrigation, coal mine ventilation, chemical engineering, communication cable sheaths and the like. The PE double-wall corrugated pipe has to complete a water closing test with corresponding requirements in the municipal drainage engineering construction process. For some corrugated pipes with larger calibers, the problems that the pipe orifice is difficult to plug, the pipe wall is easy to damage by a plugging device, the corrugated pipes are easy to loosen in a short time after plugging, and the like exist.
Disclosure of Invention
Aiming at the technical problems in the prior art, the invention aims to provide a PE double-wall corrugated pipe orifice plugging device, and in order to achieve the aim, the technical scheme adopted by the invention is as follows:
the utility model provides a PE double-walled bellows mouth of pipe plugging device, includes the bellows, bellows mouth of pipe surface is equipped with packing rubber, packing rubber agrees with the bellows surface is unsmooth, packing rubber surface is equipped with cyclic annular steel sheet, cyclic annular steel sheet passes through the clamp straining, cyclic annular steel sheet is connected with the baffle through the cable wire, the baffle blocks up the bellows mouth of pipe, it has the inflation hole to open in the middle of the baffle, the inflation hole is connected with the gasbag, the gasbag is full of after the gas with the baffle block up the bellows mouth of pipe jointly.
Preferably, the annular steel plate is welded with a steel cable, and the steel cable is welded with the baffle.
Preferably, the contact part of the baffle and the corrugated pipe is filled with a flexible waterproof material.
Preferably, the inner diameter of the corrugated pipe is 200mm, and the length of the filled rubber coated on the pipe is 200 mm.
Preferably, the annular steel plate is divided into a left block and a right block, symmetrically wrapped on the filling rubber and has the length of 140 mm.
Preferably, the baffle is a 290mm by 290mm steel plate, and the air inflation hole is positioned at the geometric center of the baffle.
Preferably, the butt-joint gap of annular steel sheet is located directly over and under, and the gap width is 20 ~ 30mm, and the tightening up mouth of clamp is left and is placed directly over.
According to the PE double-wall corrugated pipe orifice plugging device, the baffle is fixed at the pipe orifice through the annular steel plate and the steel cable, and an external stress object is not required to be arranged to fix the baffle, so that a water closing test is safer and more reliable; the annular steel plate and the corrugated pipe are connected through the rubber matched with the corrugated pipe in a concave-convex mode, the corrugated pipe can be stressed uniformly when the baffle plate bears pressure and the annular steel plate bears pressure, and the damage of a corrugated outer ring caused by overlarge local stress can be avoided.
