Abstract

The utility model discloses an unplasticized polyvinyl chloride (UPVC) composite downcast pipe which comprises a pipe body and a pipe plug. The pipe body comprises an inner pipe and an outer pipe. At least three filtering holes are formed in one end of the inner pipe close to a pipe plug, and filtering gaps are evenly distributed on the outside of the outer pipe. The pipe plug is a conical pipe plug. The inner pipe is a cast iron pipe, the outer pipe is a UPVC pipe, and the pipe plug is a cast iron pipe plug. By means of the design, the pipe can be easily inserted underground compared with the prior pipe plug and can be easily pulled out after operation, so that the pipe can be used repeatedly. The outer pipe is characterized in that the filtering gaps are directly machined in the UPVC pipe wall through a high-tech slotting technology, sufficient water can be extracted, fine sand is directly filtered and retained on the outside of the pipe wall, only a water layer is extracted, strict rainwater operation is ensured, and loss of a water pump and parts is reduced. Meanwhile, the UPVC composite downcast pipe is made of a UPVC material, is light in weight and convenient to install, greatly reduces labor intensity and improves engineering efficiency.

Description

A kind of UPVC composite water-reducing pipe
Technical field
The utility model relates to a kind of downcomer, particularly a kind of UPVC composite water-reducing pipe.
Background technology
Market generally use be all cast iron pipe, specification is 4 meters or 6 meters one, on tube wall, process the chimney filter of 1 meter, the circular hole of manually beating 1-2 centimetre left and right diameter for chimney filter part, then the screen cloth of outsourcing different densities is built precipitation, but the easy oxide etch of cast iron pipe, the nylon wire wrapping also easily comes off or draws and splits in Precipitation Process, very easily cause silt to invade in tube wall, extract out in the lump or directly block in hole together with water layer, not only greatly reduce pump-out, and needs are often changed the component of suction pump, more seriously cause dewatering of foundation unbalanced, cause the more serious geological disasters such as surface settlement.Meanwhile, because the Heavy Weight of cast iron pipe own is all increasing very large cost of labor and labour intensity aspect installation and work progress and transport.
Summary of the invention
Goal of the invention: the purpose of this utility model is to solve that existing rainfall pipe is fragile, and pump-out is low, the problem that weight is large.
Technical scheme: the utility model provides following technical scheme: a kind of UPVC composite water-reducing pipe, comprises body and pipe plug; Described body comprises inner and outer tubes; Inner tube is provided with at least three filter openings near pipe plug one end; Outer tube side is evenly distributed with filter seam.
As optimization, described pipe plug is taper pipe plug.
As optimization, described inner tube is cast iron pipe, and described outer tube is UPVC pipe, and described pipe plug is cast iron pipe plug.
As optimization, described filter seam width is 0.25mm.
Operating principle: identical with existing downcomer using method.
Beneficial effect: the utility model compared with prior art: adopt design of the present utility model, with respect to original pipe plug, be more easily inserted into undergroundly, after operation, be easy to again be extracted, to be repeatedly used.Outer tube is will filter seam by high-tech slot technology directly to process on UPVC tube wall, not only guarantee to extract out the sufficient water yield, and the tiny grains of sand are directly filtered outside tube wall, layer only draws water, ensure strict precipitation operation, and reduced the loss to water pump and component.Meanwhile, near pipe plug one end, filter opening is set in inner tube and can utilizes hydraulic pressure that water is concentrated, accelerate to draw water efficiency.This UPVC composite water-reducing pipe is UPVC material, lightweight, easy for installation, greatly reduces labour intensity, has improved engineering efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model inner tube.
Detailed description of the invention
A UPVC composite water-reducing pipe as shown in Figure 1, comprises body and pipe plug 1; Described body comprises inner tube 2 and outer tube 3; Inner tube 2 is provided with three filter openings 4 near pipe plug 1 one end; Outer tube 3 sides are evenly distributed with the filter seam 5 of 0.25mm.Described pipe plug 1 is taper pipe plug.Described inner tube is cast iron pipe, and described outer tube is UPVC pipe, and described pipe plug is cast iron pipe plug.
