Abstract

The utility model provides a sealing inspection well lid, and belongs to the underground pipe network technology in urban construction. The sealing inspection well lid aims at solving the problems that in an existing inspection well lid structure, a well mouth and a well lid are in free lap joint, so that gaps are formed in the periphery and the bottom side; holes are formed in the well lid, so that filth, mire and gravel impurities enter a well, poisons and poisonous water are generated after the impurities rot, and poison gas pollutes the environment, corrodes and damages pipelines, and threatens the life of maintainers; the well lid cannot be opened due to the fact that a pipe network is frozen and cracked in winter; more severely, the well lid is lockless, so that the well lid is easily opened, and then vehicles are damaged and people are injured. According to the new technical scheme, the section on the outer side face of a well mouth is a converged closed angle, a sealing strip is fixed to the circle of the edge of the mouth, the section on the inner side of the well lid is an open angle and is wedged with the closed angle on the outer side face of the well mouth and the sealing strip to form a wholly-sealed structure, an insulating layer and a poison gas warning box are installed on the bottom face of the well lid, and an upper lug piece and a lower lug piece which are located on the same side of the well lid mouth and the well lid are connected through fastening bolts. The sealing inspection well lid can be used for all urban construction underground pipe networks in the fields of water supply and drainage, telecommunication cable televisions, gas thermal fire control and the like.

Description

Sealed and scented well lid

Technical field:

The utility model belongs to urban construction network of underground facility technology.

Background technology:

The inspection well cover of existing Urban Buried Pipeline Network Systems is to be composed in series by well head and well lid two parts hinge mostly.The wherein well head section of being annulus, upper end have a ring-shaped step be used for support lay well lid, lower end is that a disk is laid on well body seat.Well head and well lid are free overlap joints, and also there is open gap on periphery and base.Well lid is to have through hole on a circular flat board.

Summary of the invention:

The technical problems to be solved in the utility model is, existing well head and well lid are free overlap joints, and there is open gap on periphery and base.On well lid, have through hole.Therefore all backward, corrupt and reactionary things sandstone foreign material can enter in inspection shaft, and cold air entered in well and froze winter, and well lid freezes and do not open, and well lid is easy to unexpected raising.

The technical solution of the utility model is, 1, sealed and scented well lid, it includes well head and well lid and hinge, it is characterized in that: the section of its well head (1) lateral surface is convergence and closes angle, opening's edge one is enclosed fixing seal bar (3), the section of its well lid (2) inner side is that open angle of release closes angle with the lateral surface of well head (1) and the tight wedging of weather strip (3) forms hermetic structure, the lagging casing (6) and the poison gas warning box (8) that are wrapped in insulation layer (7) are installed on the bottom surface of well lid (2), there is upper and lower auricle (5) same side at well head (1) and well lid (2), upper auricle has larger-diameter bolt hole on (5), on lower auricle (5), there is the bolt hole of small diameter, upper and lower auricle (5) couples together with fastening bolt (4), opening bolt (4) only has one section of major diameter only to open at need and use at well lid (2).

The beneficial effect of the utility model contrast background technology.

1. in prior art, well head and well lid are unconfinedly freely to overlap, its Dou You gap, periphery base, and it covers also through hole blow-by.The utility model well lid (2) is lid shape, and well head (1) and seam are buckled.The opening's edge of well head (1) has weather strip (3), a hermetically sealed inspection well cover of the tight wedging composition of its side.

2. prior art is porose a gap, and all backward, corrupt and reactionary things foreign material cold air can enter in well, corrosion, and bursting by freezing freezes to damage facility and the pipe network in well.The utility model is a hermetic structure, has insulation layer (7) the problems referred to above all can solve.

3. porose in prior art have a gap, enters after all backward, corrupt and reactionary things foreign material in well rot and produce poisonous substance poison gas, and malicious water permeates the ground, contaminated land and underground water source, poison gas rising ground pollution urban air, stay maintainer is constituted a threat in well.The utility model is hermetically sealed, and all backward, corrupt and reactionary things enter not go, and in well, also can measure in time if any poison gas poison gas warning box (8).

4. in prior art, between well lid and well head, there is gap wherein to fill up silt or freeze and be difficult to open.Simultaneously the step of well lid and overlap joint ring produces injustice as the sandstone of entering, and vehicle crosses and produces vibrations and impact sound.In the time that borehole pressure is excessive, well lid can be raised in addition, is easy to be opened and causes danger because well head and well lid are not connected well lid.The utility model is fixed up well head (1) and well lid (2) by fastening bolt (4), when occurring opening at need, can open bolt (4) the powerful jack-up of well lid (2) is come.

5. prior art is porose a gap, and all backward, corrupt and reactionary things foreign material enter in well, and water is many will be arranged, and mud is many will be removed, and particularly it produces poisonous substance after rotting, and poison gas makes in well environment very severe.The utility model is all-sealed structure, for maintainer provides a dry and comfortable clean environment.

Brief description of the drawings:

Fig. 1 is structural representation of the present utility model.

(1) well head, (2) well lid, (3) weather strip, (4) open fastening bolt, (5) upper and lower auricle, (6) lagging casing, (7) insulation layer, (8) poison gas warning box.

Detailed description of the invention:

The utility model technology detailed description of the invention illustrates as follows: first selection, can select the ductile iron that intensity is higher, and adopt die casting method.Draw the production drawing paper size of well head (1) and well lid (2) determines by actual requirement according to accompanying drawing 1, the section of its lateral surface of well head (1) is convergence and closes angle, its interior side section of well lid (2) is open angle of release, and the angle of release that closes angle and well lid (2) of well head (1) must be harmonious.Auricle up and down (5) the size dimension shape of well head (1) and well lid (2) same side is identical in addition, but the bolt hole of upper auricle (5) more greatly, the bolt hole of lower auricle (5) is less, and the production drawing of simultaneously drawing out fastening bolt (4) and unlatching bolt (4) comes.Manufacture casting mould according to above-mentioned production drawing, cast out well head (1) and well lid (2), then go out bolt hole in the upper machining of upper and lower auricle (5), process and open fastening bolt (4) by figure, finally insulation layer (7) lagging casing (6) and poison gas warning box (8) is arranged on well lid bottom surface weather strip (3) is fixed in well head (1) opening's edge, the manufacture of sealed and scented well lid has been assembled.
