Abstract

The utility model relates to a manhole base, a cover with an inspection hole. The utility model is composed of the manhole base and the manhole cover, and the inspection hole is arranged at the proper position of the plane of the upper part of the manhole cover. A hole cover is arranged in the inspection hole, and big end up slope is arranged at the joint surface of the inspection hole and the hole cover. The outwards extending end of the hole cover is extened into a groove arranged at the side wall of the inspection hole. A cross pin is connected with the well cover by horizontally penetrating through the outwards extending end of the hole cover, and, and is hinged with the well cover with relative rotation. An inserting hole for an unsealing tool is arranged at the end surface of the inspection hole cover, and is away from the position of a hinge pin. When the utility model conducts the routine observation and viewing to the underground facilities, the inserting hole cover is opened, and the whole well cover does not need being taken out. The manhole base, the cover with the inspection hole has the advantages of convenient operation, labor saving, high work efficiency, etc.

Description

Inspection shaft seat, lid that peep pole is arranged on the well lid

The utility model relates to inspection shaft seat, the lid that municipal network of underground engineering is used, and inspection shaft seat, the lid of peep pole arranged on a kind of specifically well lid

In urban construction; municipal engineering in provided underground many pipe networks; communication pipe network for example; power supply; supply water; heat supply; for pipe network and sewerage pipe networks such as combustion gas; these pipe networks are for observation; the needs of maintenance or the needs of installation; in pipe network one inspection shaft is set at a certain distance along the line; inspection shaft is provided with well seat and well lid; so that the safety and the road traffic safety of facility in the protection inspection shaft, existing inspection shaft seat; the general cast iron quality that adopts of lid, its well lid is whole; in to well, observe; need during inspection earlier well lid to be taken out to move away, and well lid is heavier, this just gives the inspection to underground pipe network facilities; observation is made troubles.

The purpose of this utility model provides the inspection shaft of peep pole seat, lid on a kind of well lid, carrying out can moving whole well lid when routine is inspected, and only needs to inspect port lid and just opens and can carry out, and reaches purpose easy to use, laborsaving, that increase work efficiency.

The purpose of this utility model is achieved in that the inspection shaft of peep pole seat, lid on a kind of well lid, form by well seat, well lid, the appropriate location of transverse plane is provided with peep pole on well lid, in this peep pole port lid is housed, there is up big and down small gradient on the mating face of described peep pole and port lid, this port lid has overhanging end to stretch into the groove of peep pole sidewall, and a lateral pin level is passed the port lid overhanging end and is connected in well lid, becomes relatively turnable hinged with well lid.

The utility model has following actively useful effect:

1. inspection shaft covers and is provided with the less peep pole in aperture, has made things convenient for the down-hole facility is carried out the customary work of observing, inspecting to carry out, and removes the maintenance of leaveing no choice but go into the well, and can take out whole well lid, and need only inspection hole cover is opened and can carry out.

2. easy to use, laborsaving.

3. the operating efficiency of improved observation, inspecting.

4. inspect port lid and be articulated in well lid, it is easy to use not only to overturn, also can prevent to inspect port lid stolen, lose.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is the profile schematic diagram of a kind of embodiment of the present utility model.

The same Fig. 1 of Fig. 2 is another embodiment profile schematic diagram.

Fig. 3 is the A-A parting view of Fig. 1, Fig. 2.

Fig. 4 is the upward view of Fig. 1, shows the bottom surface reinforcing rib structure of well lid.

Inspection shaft seat, lid that peep pole is arranged on the well lid of the present utility model, form by well seat 1, well lid 2, well lid is loaded in the well seat, see Fig. 1, Fig. 2, the appropriate location of transverse plane for example is provided with peep pole 3 in the middle part on well lid 2, port lid 4 is housed in this peep pole, described peep pole 3 has up big and down small gradient with the mating face of port lid 4, this port lid 4 has overhanging end 5 to stretch into the groove of peep pole sidewall, one lateral pin, 6 levels are passed the port lid overhanging end and are connected in well lid, become relatively turnable hinged with well lid, see Fig. 3 Fig. 4.

During enforcement, the described port lid end face of inspecting is provided with the tool insert hole 7 of uncapping away from the position of hinge pin, so that port lid is mentioned and forward the upright position to, exposes peep pole and observes.

During enforcement, described gabarit of inspecting port lid 4 is rounded, also can rectangular or other shapes, and there is up big and down small gradient on its mating face

Fig. 1 shows that rectangular well seat, lid are provided with the rectangle peep pole, also can circular peep pole be set in rectangular well seat, lid during enforcement

Fig. 2 is that circular well seat, lid are provided with circular peep pole, also can the rectangle peep pole be set in circular well seat, lid during enforcement

There is the structure of peep pole to be applicable to that the inspection shaft seat of various material manufacturings, lid comprise cast iron quality inspection shaft seat, lid on the well lid of the present utility model.

In preferred embodiment, described inspection shaft seat, lid are made with magnesite composite, and the reinforcing rib 8,9 of longitudinal and transverse setting is arranged on the following transverse plane of well lid, and described port lid 4 can be with making with seat, lid identical materials, and also available different materials is made.
