Abstract

The utility model provides an anti-theft drainage well lid. The anti-theft drainage well lid comprises a granite lid body, wherein the shape of the outline of the granite lid body is the same as the shape of the opening of an inspection well. The inspection well is sealed by placing the granite lid body into the opening of the inspection well. A set of water leakage holes are formed in the granite lid body, each water leakage hole penetrates through the two sides of the granite lid body, and water flows into the inspection well through the water leakage holes. Due to the fact that the well lid is made of granite, the strength is high, the well lid can be used for a long time and be prevented from damage, and the well lid has the good anti-theft function. Meanwhile, due to the fact that the density of the granite is high, the well lid can hardly be ejected by water flow in the inspection well, the well lid can be prevented from displacement, and potential safety hazards can be reduced. Due to the fact that the water leakage holes of the well lid are distributed in a radiated mode from the center of the well lid, rapid water drainage is facilitated.

Description

Drainage anti-theft well lid

Technical field

The utility model relates to inspection well cover, relates in particular to a kind of drainage anti-theft well lid.

Background technology

Manhole is to lead to the go out population of underground installation as facilities such as tap water, draining, telecommunications, electric power, combustion gas, heating power, fire-fighting, sanitation of environment, manhole cover is to check the openable closure of well head, bearing and well lid, consisting of, is requisite facility in urban construction.Along with developing rapidly of urban modernization, the day by day perfect and expansion of all kinds of urban operating mechanism scales and function, the quantity of all kinds of manholes is also sharply increasing.Manhole cover is the requisite part of manhole, and it can not only guarantee the coast is clear and traffic safety, is also embodying to a certain extent city image.According to the material difference, well lid mainly is divided into two classes: a class is the metal well lid; One class is non-metal well lid.The metal well lid is generally casting iron well lid and ductile cast iron manhole cover, is characterized in that cost is higher, theftproof is poor, but because its bearing capacity is high, the shock resistance fatigue resistance is good, and attractive and durable, meets the requirement of urban modernization image, thereby use amount is still maximum.The material of nonmetal manhole cover is generally concrete, steel fibrous concrete and composite material etc., is characterized in that cost is low, theftproof is high, but weight is large, poor, the easy breakage of shock resistance fatigue resistance, the life-span is short, image is poor and open inconvenient.In order to extend the application life of well lid, reduce damage and steal phenomenon, be necessary the structure of well lid is improved.

The utility model content

The purpose of this utility model is to provide a kind of drainage anti-theft well lid, to promote the antitheft and drainability of well lid.

The utility model is that the technical scheme that its technical problem of solution adopts is,

Drainage anti-theft well lid, comprise the granite lid, the appearance profile of this granite lid is consistent with the manhole opening shape, the granite lid is placed in to the manhole opening, manhole is sealed, be provided with one group of leaking hole in the granite lid, each leaking hole runs through granite lid both sides, and current enter in manhole through leaking hole;

Granite lid middle part has pellet, and each leaking hole arranges around this pellet, and in the granite lid, is uniformly distributed centered by pellet, and current are imported manhole from granite lid surrounding;

Leaking hole is along the radially extension of granite lid, and leaking hole is less than its width away from pellet one end near the width of pellet one end;

The granite lid is circular, and its thickness is directly proportional to its diameter.

The utility model has the advantage of, this well lid adopts granite to make, and intensity is higher, can use for a long time, avoid damaging, and there is anti-theft function preferably, simultaneously because granite density is higher, be difficult to by the current jack-up in inspection shaft, can prevent the well lid displacement, reduce potential safety hazard, its leaking hole radially distributes along the lid center, is conducive to rapid draining.

The accompanying drawing explanation

Fig. 1 is the structural representation of the drainage anti-theft well lid that the utility model proposes.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.

As shown in Figure 1, the drainage anti-theft well lid the utility model proposes comprises granite lid 1, the appearance profile of this granite lid 1 is consistent with the manhole opening shape, granite lid 1 is placed in to the manhole opening, manhole is sealed, be provided with one group of leaking hole 2 in granite lid 1, each leaking hole 2 runs through granite lid 1 both sides, and current enter in manhole through leaking hole 2;

Particularly, granite lid 1 middle part has pellet 3, and each leaking hole 2 arranges around this pellet 3, and in granite lid 1, is uniformly distributed centered by pellet 3, and current are imported manhole from granite lid 1 surrounding;

Further, leaking hole 2 is along the radially extension of granite lid 1, and leaking hole 2 is less than its width away from pellet 3 one ends near the width of pellet 3 one ends;

In the present embodiment, granite lid 1 is circular, and its thickness is directly proportional to its diameter.

This well lid adopts granite to make, intensity is higher, can use for a long time, avoid damaging, and there is anti-theft function preferably, simultaneously because granite density is higher, be difficult to by the current jack-up in inspection shaft, can prevent the well lid displacement, reduce potential safety hazard, its leaking hole radially distributes along the lid center, is conducive to rapid draining.

Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
