Abstract

The utility model provides a multifunctional city sewage and rainwater manhole, and relates to the urban public drain facilities. The utility model consists of a lining fixed on the well edge, and a well cover. The underside of the lining is provided with a flange, on which a protective net is arranged, and the protective net is arranged on the underside of the well cover. The net holes of the protective net can be rectangular, round, elliptical, rhombic, triangular, right pentagonal, or right hexagonal. The long axis sizes of the net holes are not more than 10 cm. The protective net is made of glass steel or high strength plastic. The well cover and the lining are hinged together by a hinge shaft. The utility has strong theft preventing performance, can be opened for flood discharging during heavy rain, and can prevent the passengers from falling into and causing damage. The protective net can be taken out after the well cover is opened when the draining system is overhauled.

Description

Multi-functional municipal sewage rainwater inspection shaft lid

Technical field

The utility model relates to the public plumbing facility in city, a kind of multi-functional municipal sewage rainwater inspection shaft lid used when urban sewerage and drainage system maintenance, mediation of more clearly saying so.

Background technology

Municipal sewage rainwater inspection shaft lid is the well lid of urban sewerage and drainage system sink hole, catch-basin, the usefulness during for maintenance facility, cleaning dirt, dredging pipeline.It generally is to use lining of cemented on the vertical shaft well of crossing over drainage pipe, and a well lid is installed on lining again.Lining and well lid are by the cast iron manufacturing.

The well lid of this cast iron manufacturing generally just is placed on the lining.Therefore, some unprincipled fellows often spirit away, steal and steal it.This situation causes damage to country on the one hand; On the other hand, also be prior, pedestrian or vehicle are fallen in the inspection shaft, cause the disastrous effect of pedestrian's injures and deaths, vehicle damage.Existing sewage rainwater inspection shaft lid is the critical facility of urban sewerage and drainage system.Not very big when rainwater, when drainage system can operate as normal, sewage rainwater inspection shaft lid was placed in and also is in the normal position in the lining.But next interim when torrential rain, excess surface water often has little time to leak into drainage system.For this reason, usually need directly well lid to be opened, the ponding on the road is entered in the well quickly.In this case, because rainwater usually covers well head even becomes a vast expanse of water, pedestrian or vehicle be can't see the position of well head, and the possibility of falling in the inspection shaft is just bigger, and be also just more dangerous.So existing sewage rainwater inspection shaft lid exists in easily robbed or burgled, robbed or burgled back and the heavy rain pedestrian and vehicle and easily is absorbed in defective such as cause danger.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provide a kind of have can open flood discharge in antitheft mistake, the heavy rain, lose that pedestrian and vehicle in back or the heavy rain can not fallen into, safe and reliable multi-functional municipal sewage rainwater inspection shaft lid yet.

Summary of the invention

In order to achieve the above object, the utility model is made of lining that is fixed on the inspection shaft well and the well lid that is installed on the lining.The bottom of lining has flange, and protective screening is installed on the flange, protective screening be positioned at well lid below.The mesh of protective screening can be a kind of in rectangle, circle, ellipse, rhombus, triangle, regular pentagon, the regular hexagon.The size of the major axis of the mesh of protective screening is not more than 10 centimetres.This protective screening can be protected pedestrian and vehicle under the situation that well lid is lost or well lid is opened, avoid being absorbed in the danger in the well, the disastrous effect of having avoided pedestrian's injures and deaths, vehicle to damage.The size of the major axis of mesh is not more than 10 centimetres, can guarantee that the child who finds one's feet also is unlikely to fall into the down-hole, and is safer.

Protective screening is made by glass fiber reinforced plastic, can avoid losing or robbed or burgled.Protective screening is made by the highstrenghtpiston, and the value of using for other purposes is also little, thereby also can avoid losing.

One side of well lid has convex shoulder, has transverse holes on the convex shoulder.The corresponding position has groove on the lining, also has transverse holes on the groove.Well lid and lining borrow transverse holes hinged with hinge.This structure has strengthened theftproof performance greatly, does not add to destroy and can't spirit away.In addition, do not influence use yet, open and open well lid and get final product.Also have lock with the hinge opposite position on well lid and the lining.Further improved its theftproof performance

Task of the present utility model comes to this and finishes.

Of the present utility model provide a kind of have can open flood discharge in antitheft mistake, the heavy rain, lose that pedestrian and vehicle in back or the heavy rain can not fallen into, safe and reliable multi-functional municipal sewage rainwater inspection shaft lid yet.Its theftproof performance is strong, can open flood discharge when raining heavyly, can open well lid during the drainage for overhaul system again and take out protective screening, and is easy to use.But its wide popularization and application is on municipal sewage rainwater inspection shaft and other inspection shaft.
