Abstract

A manhole pedestal is characterized in that: the manhole pedestal, formed through injection molding to be a whole body, comprises a bottom and a sidewall; the bottom is positioned at one end of the sidewall; two symmetric ports that are arc bodies are arranged on two sides of the sidewall; a reinforcement stand is disposed outside each port and is equipped with first transverse and vertical reinforcement ribs; second transverse and vertical reinforcement ribs are disposed outside the sidewall; butt joint portions are mounted on the manhole pedestal and are provided with first fixing holes; two symmetric prefabricated ports are disposed on the two sides of the sidewall, and each prefabricated port is composed of semicircles with different diameters; and the front end of each prefabricated port is enclosed, and the prefabricated ports and the ports are arranged on the sidewall in a cross manner. Through standard members formed by injection molding, the manhole pedestal is improved in general utilization and convenient for construction. Plastic materials are adopted to enable antioxidation and corrosion-resisting properties to be improved. The manhole pedestal is equipped with the first reinforcement ribs and the second reinforcement ribs so as to be prolonged in service life.

Description

Manhole base

technical field

The utility model relates to a kind of underdrainage, blowdown manhole for municipal engineering, and particularly high, the easy construction of a kind of generalization, good airproof performance, antioxidant anticorrosive performance are good, easy to use, long service life and the manhole base that adopts plastic material to make.

background technology

Under existing municipal engineering land used, webmaster manhole mostly is brick concrete inspection well, mainly there is following shortcoming in it: first intensity is low, the support strength of brickwork construction is low, especially near the brickwork construction reducing reducing part on road surface, because the horizontal active force of imbalance impacts, easily subsides; Secondly well body construction cycle long, construction is complicated, owing to must piling up at manual scene, high to civil engineering requirement, standardization, generalization, seriation degree are poor, by hand and materials number be the key factor that affects quality; Exist in addition and can not change, easily break and seepage and the defect such as pollute, need frequently keep in repair.

summary of the invention

Technical problem to be solved in the utility model is to provide that a kind of generalization is high, easy construction, good airproof performance, antioxidant anticorrosive performance are good, easy to use, long service life and the manhole base made of plastic material, the above-mentioned defect existing to overcome existing manhole.

The technical scheme of the utility model technical solution problem is as follows: manhole base is integrated injection molded, manhole base comprises bottom and sidewall, bottom is positioned at one end of sidewall, the both sides of sidewall arrange two symmetrical interfaces, this interface is arc body, interface outside arranges reinforced seat, this reinforced seat arranges the first horizontal and vertical reinforcing rib, the second horizontal and vertical reinforcing rib of outer setting of sidewall, manhole base arranges docking section, the first fixing hole is set on docking section, the both sides of sidewall arrange two symmetrical prefabricated interfaces, this prefabricated interface is comprised of the semicircular body of different-diameter, and the front end of this prefabricated interface sealing, and prefabricated interface and interface are alternately arranged on sidewall.

As preferably, the end face of interface is semi-annular shape.

The beneficial effects of the utility model are: by the standard component of injection mo(u)lding, the generalization of manhole base is improved, make easy construction, adopt plastic material to improve anti-oxidant and decay resistance, manhole base arranges the application life that the first reinforcing rib and the second reinforcing rib have improved manhole base.
