Abstract

A rigid alloy plastic bridge drain pipe comprises an embedded pipe body and a lower adapter; the lower end of the embedded pipe body is connected with the upper end of the lower adapter; a limit stand is arranged on the inner wall of the lower end of the embedded pipe body; a downstream seepage-proof eave is arranged on the edge of the limit stand; the upper end of the lower adapter is connected to the inner wall of the embedded pipe body on the outer side of the downstream seepage-proof eave through threads; a pitted surface layer is arranged on the outer wall of the embedded pipe body; outward seepage-proof concave-convex grooves are formed in the pitted surface layer; the embedded pipe body is made of rigid alloy plastic, and the rigid alloy plastic is formed in a manner that PC, PBT, PET and ABS are synthesized and are subjected to extrusion granulation at 250-350 DEG C and then injection-compression moulding by an injection molding machine die. The rigid alloy plastic bridge drain pipe has the advantages of being strong in antioxidant properties, corrosion-resistant, higher in mechanical strength, non-aging, free from toxin decomposition, acid-resistant and alkali-resistant, heat-resistant and weather-resistant, good in dimensional stability and impact resistance performance and high temperature-resistant and cold-resistant, and is adapted to diverse climates and severe environments.

Description

Stiff alloy plastics bridge water discharge pipe
Technical field
The present invention relates to bridge pipeline technical field, specially a kind of stiff alloy plastics bridge water discharge pipe.
Background technology
With social development, increasing tubing is used in real life.And due in actually used tubing, meeting The tubing of different length is connected with each other and forms a tubing passage.Wherein bridge water discharge pipe is applied to railway and highway bridge The engineering fields such as beam, guardrail, undertake the task of rain-water drainage, and to safeguarding bridge floor quality, ensuring safety current plays significant role.
Bridge water discharge pipe can be divided into cast iron tapping pipe, pvc tapping pipe according to material.Both tapping pipes all exist and lack as follows Point:
Cast iron tapping pipe drain pipe is too coarse, causes energy waste, and the corrosion contamination in use having is serious, special It is not the spot that cement surface often leaves rust;And there is processing and manufacturing difficulty, production cost height in cast iron tapping pipe, install The shortcomings of difficulty is big.
The antioxygenic property of pvc tapping pipe, decay resistance, mechanical strength be not all high, but also there are catabiosis, resistance to Hot weatherability, dimensional stability and impact resistance extreme difference are it is impossible to adapt to outdoor various weathers and adverse circumstances for a long time.
The cast iron tapping pipe smooth surface processing was done, with construction material adhesive strengths such as cement in pvc tapping pipe or surface Too little, easily formed and produce gap from bone, water oozes out from gap, causes bridge base plate watermark, and the barrier performance that blocks water is poor.
Content of the invention
Technical problem solved by the invention is to provide a kind of stiff alloy plastics bridge water discharge pipe, to solve the above-mentioned back of the body The problem proposing in scape technology.
Technical problem solved by the invention employs the following technical solutions to realize:
Stiff alloy plastics bridge water discharge pipe, including pre-buried body and lower linking tube, connects under the lower end of described pre-buried body is same The upper end screwed connection of pipe, the lower end inner wall of described pre-buried body is provided with limiting stand, and the edge of limiting stand is provided with suitable Water antiseepage eaves, described limiting stand and downstream antiseepage eaves are ring-type, and the upper end of described lower linking tube is being prevented downstream by screwed connection Ooze on the pre-buried inboard wall of tube body outside eaves, the lateral wall of pre-buried body is provided with pitted skin layer or leather lamina, on described pitted skin layer Be provided with anti-extravasation tongue and groove, described pre-buried body is made up of stiff alloy plastics, described stiff alloy plastics by pc, pbt, pet, Abs synthesis, through 250~350 DEG C of high temperature extruding pelletizations, passes through injection machine mould injection-compression molding afterwards.
Further, above-mentioned pc, pbt, pet, abs synthesize first becomes pc/pbt, pc/abs, pc/pet engineering plastics, Secondly synthesize stiff alloy material on the basis of the above.
Further, described pre-buried body is straight barrel type or curved tubular.
Further, the lower surface of described pre-buried body is set to inclined plane.
Beneficial effects of the present invention are as follows:
1st, there is the antioxygenic property of extra-heavy, corrosion resistance, have higher mechanical strength, and there is not aging, no toxin Decompose, acid and alkali-resistance, heat-resisting weatherability, dimensional stability and shock resistance extremely strong, high temperature resistant cold resistance, adapt to various weathers and Adverse circumstances;
2nd, the pitted skin layer on the lateral wall of pre-buried body and put infiltration tongue and groove in order to increase with building contact surface, strengthen Adhesive force, block water antiseepage, realizes tapping pipe and bridge perfect adaptation.
