Abstract
The utility model discloses a reinforced plastic inspection chamber bottom plate by a hot extrusion cold press forming method, comprising a plane-shaped bottom plate body, wherein convex reinforced blocks formed into a whole body with the bottom plate body are arranged on the bottom plate body. The utility model adopts a plastic extruding machine to extrude the molten plastic, and then the plastic inspection chamber bottom plate is die-casted by a press and a mould so as to achieve the force-bearing requirements of a plastic inspection chamber, and solves the difficult problems that the plastic inspection chamber bottom plates need to produce in batches.
Description
Technical field
The utility model relates to a kind of plastic inspection well that is used for blowdown, relates in particular to a kind of enhanced plastic manhole base plate of hot extruding and cold press.
Background technology
For constructing of buried pipeline manhole, traditional method is after digging pit in place, the position of manhole, builds by laying bricks or stones or the shaft bottom of concreting with loam brick, builds pit shaft by laying bricks or stones with loam brick again and is communicated with buried pipeline, shaft in wall is smeared concrete, and walling crib and well lid are installed then.Adopt not only complex procedures of cast-in-place method, troublesome poeration, long construction period, the influence that engineering is subjected to artificial and natural environment is bigger, and quality is difficult for guaranteeing.
In order to solve the problem that above-mentioned brick manhole exists, plastic inspection well has appearred.The blowdown of making both at home and abroad at present is mainly the injection moulding formula and is wound in pattern with straight tube plastic inspection well production technology, the injection moulding formula is produced plastic inspection well and is adopted raw material to be generally polyvinyl chloride (PVC), and Wrapping formed plastic inspection well is a raw material with polyethylene (HDPE) basically then.Existing plastic inspection well base plate generally adopts plastic plate directly to cut and forms, again plastic bottom board that cutting is obtained and plastic inspection well well body welding fabrication.Adopt the plastic inspection well base plate of said structure because the difficult problem of polyethylene board production equipment, technology, cost performance aspect is essentially the 10mm thin plate so far on the market.As adopt the polyethylene board of this thickness, then since thickness low LCL and strength deficiency to reach the plastic inspection well force request, the design that directly influences plastic inspection well diameter and buried depth is used, if adopt existing thicker polyvinyl chloride (PVC) sheet material, then because the welding that the material difference can not solve plastic inspection well polyethylene (HDPE) pit shaft and polyvinyl chloride (PVC) base plate.
The utility model content
The purpose of this utility model is to overcome the problems referred to above that existing plastic inspection well base plate exists, and a kind of enhanced plastic manhole base plate of hot extruding and cold press is provided.The utility model adopts plastic extruder to extrude molten plastic, by press and moulding form die cast plastic inspection well base plate, reaches the plastic inspection well force request again, has solved the difficult problem of plastic inspection well production in enormous quantities base plate demand.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of enhanced plastic manhole base plate of hot extruding and cold press is characterized in that: comprise the base plate body that is plane, the base plate body is provided with the convex boss with base plate body integral molding.
Described boss is a plurality of.
Described boss is evenly distributed on the base plate body.
Rounded or the polygon of described base plate body.
Adopt advantage of the present utility model to be:
One, the utility model is by hot extruding and cold press, and shape is accurately unified, and is not yielding, for next step welding sequence provides assurance, has reduced the existing molten base plate that sticks into pattern plastic inspection well bottom technique and has cut and trimming.
Two, the utility model constitutes one because the base plate back side is different convex boss, and a plurality of convex boss is even is distributed on the base plate body, can reach the plastic inspection well force request, has improved the manhole base plate strength.
Three, the utility model has improved base plate production efficiency, has alleviated labor strength, and stick into pattern and compare with molten, owing to reduced operation, thus reduced cost of production.
