Manufacturing method of plastic concrete inspection well

Abstract

The invention discloses a manufacturing method of a plastic concrete inspection well, which comprises the following steps of: heating a plastic, extruding the plastic into a belt or a strip through a plastic extruding machine, using the obtained belt or the strip and a small amount of steel bars for weaving to form a cage-shaped framework of a formed part, placing into a cavity formed by an inner mold and an outer mold, casting concrete and adding trace plastic fibers into the concrete. By adopting the manufacturing method, the inspection wells in different specifications can be produced, centralized forming can be performed in a factory, the inspection well can be divided into sections for modular manufacturing, and then field assembly is performed, thereby overcoming inconvenience and cumbersome property caused by field construction; and simultaneously, the product is corrosion-resistant and reliable in quality.

Description

technical field

[0001] The invention generally relates to a composite material product, in particular to an inspection well made of a composite material made of plastic as a skeleton and concrete. technical background

[0002] Existing drainage and sewage inspection wells for municipal construction generally use brick inspection wells, concrete inspection wells and plastic inspection wells. Brick inspection wells can be constructed flexibly, and it is a traditional practice to adapt to different places. Due to its low strength, poor pressure resistance, easy damage, poor anti-seepage ability, and short service life, it has been replaced by other materials. And to drainage in the municipal engineering, blowdown pipe, generally larger, darker, the well of brick laying has been difficult to adapt to needs. The advantages of plastic inspection wells are corrosion resistance, acid and alkali resistance, light weight, long service life, simple construction, and fast discharge. ...

Examples

Embodiment Construction

[0008] Utilize plastics such as polyethylene or polypropylene, which are easy to form and have certain strength characteristics, add polyethylene or polypropylene resin to glass fiber, coupling agent, heat and extrude various shapes required, including cross-section into square and rhombus , round, oval and special-shaped strips of different sizes, different thicknesses, and various strips of different widths, such as forming a strip with a width of 20mm and a thickness of 2-5mm, the strip is 5-10mm in diameter, and then according to the concrete Check the requirements of the well, weave the formed strip and strip plastic products into a cage shape, like a concrete well shaft or round, square, fan-shaped, the size of which is 6-8 meters deep and about 1 meter in diameter. , the way of weaving is to weave vertically and horizontally, and each water branch pipe can also be reserved or knitted according to the size. When weaving plastic cages, according to the stress state, choos...
