Abstract
The utility model relates to a concrete well cover of composite materials, which belongs to the field of a sewage and a sewage well, particularly a well cover used on inspection wells in telephone and communication lines. The utility model is composed of a steel ring, a steel bar framework, a steel net, a concrete composite material and a steel fibre mixture. A step is arranged on the edge of the bottom surface of the well cover. The utility model is convenient to be matched with the original well cover seat due to the arrangement of the step. The thickness of the middle part of the well cover is enhanced. The utility model has the advantages of convenient fabrication, high strength and strong anti-folding capability. The service life is a product is enhanced. The problem that a well cover which is made of steel and fiber composite materials is used for replacing a cast iron well cover is solved. The utility model is the well cover which is suitable for being used for municipal engineering.
Description
Technical field the utility model composite material concrete manhole cover belongs to sewer, sink hole field, the well lid on particularly a kind of manhole that uses in phone, communication line.
The various manholes in the existing phone of background technology, the communication line and the well lid of uses such as sewer, sink hole are to adopt the cast iron materials manufacturing, cause well lid to lose easily, lose in order to prevent casting iron well lid, adopt the manufacturing of composite material concrete, but because after original well lid loses, changing the composite material concrete manhole cover need be with the supporting replacing of manhole cover base, too high for the various manhole costs in phone, the communication line, and existing composite material concrete manhole cover and the original manhole cover base cover that mismatches, bring a lot of inconveniences to the user.Because original casting iron well lid thickness is less, adopt the composite material concrete manhole cover can cause insufficient strength, do not meet municipal requirement.
The purpose of this utility model is to avoid the weak point of existing well lid and provides a kind of replacing convenient, the composite material concrete manhole cover that matches with original manhole cover base.
The content the purpose of this utility model of utility model reaches by following measure; it is by steel ring; cage of reinforcement; steel mesh; the mixture of concrete composite material and steel fibre is formed; the edge of well lid is a steel ring; steel ring and cage of reinforcement weld together, and well lid is provided with open hole, are provided with open hole protection steel ring at the open hole place; the outward flange of well lid bottom surface is provided with a circle step; because the setting of step can make things convenient for original manhole cover base to match, also the thickness in the middle part of the well lid has been improved simultaneously; strengthen the intensity of well lid on the composite material coagulation greatly, met municipal requirement fully.
For the intensity of reinforced composite concrete manhole cover at the step place, form a bending step at the step place at the cage of reinforcement of bottom surface portions, make the steel bars in concrete skeleton consistent with the well lid surface engagement.
Because original manhole cover base is provided with depression, in order further to cooperate manhole cover base, the circle step of one on the edge of well lid bottom surface is provided with a circle depression, because a circle depression that is provided with on the step can cooperate manhole cover base, well lid and manhole cover base are more suitable.
The steel ring at well lid of the present utility model edge can adopt L type angle steel.
Well lid of the present utility model can be square, circle, rectangle.
The well lid of the present utility model also row's of going for rainwater is used, and well lid is provided with a plurality of drain holes, and rainwater flows out from drain hole.
The utility model is made simple, the intensity height, and flexural capacity is strong, and improve the application life of product, solved the problem that the well lid made from the steel fiber composite material is changed casting iron well lid, is a kind of well lid that municipal engineering are used that is suitable for.
