Abstract
A manhole cover and its seat is disclosed, which is made of composite material instead of cast iron and concrete. Its advantages include not rusting, light weight, and no reclaiming value.
Description
Composite material of the present invention is water (feedwater, sewage, rainwater), the electricity (forceful electric power, light current) that is replaced in present use, the manhole cover and the well seat of interrogating (communication), gas (steam, natural gas) etc.
Present water, electricity, news, vapour manhole cover, well seat are all made with concrete and steel concrete and cast iron.The weight of concrete inspection well lid has 70 to 90 kilograms, and it is very difficult to uncap, and it is careless to close lid, hurt sb.'s feelings and breaks well lid into pieces.The corrosion of cast iron well seat is fast, though well lid is not heavy, is worth but cast iron has regeneration, and often stolen, it is untimely to augment lid, will cause car accident and personal injury.
The present invention is heavy according to concrete manhole cover, and fragile, the casting iron well lid corrosion is fast, easily stolen defective and the composite drain cover, the well seat that design.It has body light (well lid heavily is no more than 15 kilograms), and non-corrosive, 50 years are aging, can not regenerate (robber goes useless), advantage such as fire-retardant, and load-carrying, shearing resistance, anti-impact force are all greater than casting iron well lid.
The Main Ingredients and Appearance of composite material, by being that " 191 " number polyester adds initator, accelerator, flexibilizer, fire retardant, abrasion-resistant powder, CWR4 * 4 grid glass fabrics, steel mesh, stirrup are formed.
It will replace trap drainage basketry on various manhole covers, well seat and highway limit that existing cast iron concrete makes composite material.
Describe in detail below in conjunction with accompanying drawing
Well seat 1: periphery is provided with eight reinforcing ribs, gains in strength and be convenient to and fix with concrete.It is three kinds that the degree of depth is put at the well seat, be used in light, in, heavy three kinds cover.
Well lid 2: divide three kinds equally.Light-duty sidewalk and the location not under pressure of being used in.The medium-sized cargo location that is no more than a ton that is used in.Heavy type has been used in heavy vehicle and has passed through the location.
The zinc-plated net 3 of electric welding: be used on the heavy well lid.
For rib stirrup 4: be used on the heavy well seat.
Claims (2)
1, manhole cover made of composite material and well seat; It is to use unsaturated polyester resin (196# mylar), and content 100 adds (initator)---cyclohexanone peroxide is white pasty state 3%, adds accelerator (curing compound) again---, and bitter edible plant acid solution is an aubergine liquid 2%; Add flexibilizer (phthalic acid) dibutylester 5% again, add anti-wear agent (corundum) 10% again, the CWR400-9 glass fabric, zinc-plated electric welding steel mesh is for compositions such as ribs.
2, according to claim one:
Under manhole cover made of composite material and well seat divide light-duty, medium-sized, heavy three kinds.Light-dutyly be used in the sidewalk and do not have the pressurized location.Medium-sizedly be used in the road that dolly and the loads below a ton pass through.Heavy type is used in the road that heavy-duty car and equipment pass through.Heavy well seat is added with for the rib stirrup, and thickness is 20 millimeters, and the bottom is added with well word muscle, and the middle level is added with zinc-plated welding steel mesh.
