Background

After the self-reformation of China is opened, the original control on population mobility is gradually released, a large amount of rural workers are rushed to cities, and the rapid development of the urbanization process brings a large amount of rural villages in cities to China. The transformation of urban-rural areas is not only an important component of the urban-rural overall strategy, but also the key point of the 21 st century Chinese urban management. Due to objective reasons such as life style and sanitary facilities, the phenomena of disordered pipe network layout, mixed rain and sewage, private reception and candid photograph are common, drainage and pollution discharge are not smooth, waterlogging and overflow are serious, and the reconstruction of a drainage system can be called as the important importance of the reconstruction of urban villages and rural villages. At present, rain and sewage diversion transformation is mostly carried out, so that the influence of overflow mixed flow sewage on a river channel can be reduced, the living environment is improved, and the urban image is improved; and the design water volume of a sewage treatment plant can be reduced, the instantaneous water volume in the rainfall period is reduced, and the stable operation of the sewage treatment plant is ensured.

The inspection well is an accessory structure which is convenient for regular inspection in a drainage system, and the currently used inspection well cover is mostly made of cast iron, concrete, regenerated resin and the like and is an opaque well cover; the operating personnel can not judge the water flow condition in the pipeline under the condition of not opening the well lid.

Therefore, the design of the transparent glass fiber reinforced plastic inspection well cover can solve the problem to a great extent,

SUMMERY OF THE UTILITY MODEL

One of the purposes of the utility model is to overcome the shortcoming that exists among the prior art, provide an inspection shaft well lid, can conveniently improve the in-process and examine the current situation system when troubleshooting, completion acceptance check whether have sewage inside the catch basin directly perceivedly to can judge rapidly whether thorough of distribution transformation of rain and sewage.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

a manhole cover for non-roadways comprises a transparent manhole cover, a manhole seat and a gasket; the well seat is arranged along the edge of an opening at the top of the well chamber, the well cover is arranged on the well seat, and the gasket is arranged on the contact surface between the well cover and the well seat; a plurality of anti-surge drainage holes are formed in the well cover, and opening holes are symmetrically formed in the gasket by taking the center of the well cover as a symmetrical point; the one end of well lid with the packing ring is articulated and the relative other end corresponds the packing ring position with it has the opening socket to reserve between the well lid.

Further, still pile up around the well lid and be higher than the concrete rail of well lid.

Furthermore, the top inboard of well seat is equipped with stair structure, the well lid edge sets up on the step face.

Further, the gasket is distributed on the surface of the step structure and the top surface of the well seat.

Furthermore, the anti-surge drainage holes are uniformly distributed in an annular manner by taking the center of the well cover as a circle center; the kick drain hole is a well lid diameter from the well lid center 1/3.

Further, the concrete fence is 20cm high and 10cm thick.

Further, the opening socket is a rectangle of 20mm x 8 mm.

Furthermore, the opening hole is circular or key hole-shaped and is 1/500-1/1000 of the area of the well lid.

The technical scheme of the utility model can reduce personnel by a wide margin and at the number of times of investigation with the inspection and acceptance of this drainage system in-process well lid, directly the observation is clear to effectively use manpower sparingly, raise the efficiency. And, because this technical scheme is applicable to and installs on non-roadway, consequently can avoid influencing normal transportation on the one hand, on the other hand, the concrete rail can play the guard action, avoids the well lid to lead to the visual variation of inspection shaft well lid because of stepping on the quick wearing and tearing of action such as step on.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Reference is made to the accompanying drawings. The embodiment comprises a well lid 1, a well seat 7 and a gasket 4. The well lid 1 is round and smooth, colorless and transparent, and the center has a character mark 3, and the well is a rainwater or sewage inspection well. Well seat 7 sets up along well room top opening edge, and the top inboard of well seat 7 is equipped with the stair structure, thereby well lid 1 passes through the edge setting fixed mounting on the step face. The well lid 1 sets up on well seat 7 and the contact surface between well lid 1 and the well seat 7 is equipped with packing ring 4. Specifically, the gasket 4 is disposed on the surface of the stepped structure and the top surface of the well seat 7. In order to prevent the manhole cover 1 from being worn rapidly due to treading, a concrete fence 9 higher than the manhole cover 1 is piled around the manhole cover 1, and the concrete fence 9 is 20cm high and 10cm thick in the embodiment. In particular, a part of the bottom of the concrete fence 9 is cast on the well base 7, and the other part is cast on the upper part of the well chamber.

The well lid 1 is provided with a plurality of anti-surge drain holes 2 which are uniformly distributed in an annular shape by taking the center of the well lid 1 as the center of a circle. The back-flush outlet 2 in this embodiment is 8 and the distance apart from well lid 1 center is the 1/3 diameter of well lid 1, and every two back-flush outlets 2 and the central contained angle that forms of well lid 1 are 45. One end of the well lid 1 is hinged with the gasket 4, an opening socket 5 is reserved between the position of the gasket 4 corresponding to the other end opposite to the one end of the well lid 1 and the well lid 1, and the opening socket 5 is a rectangle of 20mm multiplied by 8 mm. Certainly, the well lid 1 can also be square, and the well seat 7 can be adjusted according to the shape adaptation of the well lid 1.

Meanwhile, the gasket 4 is symmetrically provided with two opening holes 6 by taking the center of the well cover 1 as a symmetrical point. The opening hole 6 is circular or key hole shaped and is 1/500-1/1000 of the area of the well lid 1. The opening hole 6 is circular with a diameter of 30mm in the present embodiment.

During construction, the well diameter of the inspection well is determined according to the diameter of the water drainage pipe and the buried depth of the water outlet pipe pipeline, and the construction of the well chamber 8 is completed; and then completing construction of a well seat 7 according to the attached drawing, installing the transparent glass fiber reinforced plastic inspection well cover 1 after placing the gasket 4, and finally building a circle of concrete fence 9 around the inspection well. The fence had a height of 20cm and a thickness of 10 cm. The size can be adjusted as required.
