Description

Si-Mg concrete manhole well lid

The utility model relates to a kind of overburden of underground structure mesopore well head, especially a kind of well lid of manhole shaft.

In known technology, existing city municipal drainage, water supply, coal gas, the caliduct of being used for, the hole cover of the manhole shaft of system such as communication cable, power cable, main casting iron well lid or the cement concrete well lid of forming by wellhead receptacle and cover plate, but casting iron well lid easy-to-rust, cost height, also usually destroyed or steal and sell, make Kong Jing become trap by the lawless person; And cement concrete well lid structure heaviness, moulding is coarse, brings inconvenience for again installation and use.

The purpose of the utility model provides a kind of novel structure, firm light, the moistureproof rotproofness of quality is good, cheap, and novel manhole cover simple and easy, safe and convenient to use is installed.

For achieving the above object, the technical scheme that the utility model is taked is: adopting and filling context layer, layer 2-4 glass fiber layer of cloth and 1-3 layer bamboo weaving net muscle by the 2-6 of the company of notes layer Si-Mg concrete in the Si-Mg concrete lid is to strengthen skeleton to connect the silicon magnesium cover plate of being formed through co-molded, by the bamboo rope sling circle of annotating repeatedly body in the Si-Mg concrete pedestal and stranded bamboo sheet ring is to strengthen skeleton to connect the silicon-magnesium-concrete wellhead base of being formed through mold pressing, the cover plate embedding is placed on wellhead receptacle is combined into novel Si-Mg concrete manhole well lid.

Because the utility model is the well lid of Si-Mg concrete structure, it is better than the moistureproof corrosion resistant performance of existing casting iron well lid, cost is low, saves resource, because of no recovery value, be difficult for destroyed and stolen, than cement concrete well lid light weight, moulding fineness, easy for installation.Its novel structure, design innovation, energy-conservation profit are useless, firm durable, easy to use, can be applicable to the underground manhole shaft of systems such as urban water supply, draining, gas flue, telecommunications, electric power, are a kind of novel manhole cover.

Below in conjunction with drawings and Examples the utility model is described in further detail.
