Abstract

The utility model relates to a well cover used for a sewage pipe network, which comprises a well cover support arranged at a well mouth and a well cover for covering the well mouth. The well cover is characterized in that the well cover comprises a well-cover edge frame and a well-cover bottom arranged on the well-cover edge frame; reinforcing ribs and stress-relief holes formed by the reinforcing ribs are arranged at the inner part of the well-cover edge frame; and the well cover is fixedly connected to the well cover support through bolts. The well-cover bottom is connected on the well-cover edge frame by means of hot-melt welding. Sealing strips are arranged between the well cover and the well cover support. Since the well cover is provided with the plurality of stress-relief holes, the stress on the whole well cover is released. The well-cover bottom is arranged at the bottom of the well cover by the hot-melt welding process, so that the well cover is hollow and provides an upward pressure and a downward pulling force, thereby increasing the bearing capacity of the well cover. Additionally, with the existence of the stress-relief holes of the well cover, the weight of the well cover is greatly reduced and the manufacturing cost is also reduced, thereby overcoming the defects of large weight and small bearing capacity of the prior well cover.

Description

A kind of sewage network well lid

Technical field

The utility model relates to a kind of sewage network building unit, relates to a kind of manhole cover that is arranged on sewage network and the road specifically, relates to the inspection shaft lid that the manhole of the closed that a kind of polymer composite makes props up in particular.

Background technology

It is the common building unit in a kind of sewage network road construction field that the closed manhole cover props up, and comprises well lid and support.Common sealed well lid is made by materials such as cast iron, nylon, glass fiber reinforced plastic, cement at present, all has certain thickness, can have enough strength support vehicles, as the impact of various vehicles and the anti-lift of dirty gas of network of underground and sewage.Therefore present all very heavy frangible, the blow-by of well lid, not only outward appearance is outmoded but also bearing capacity is poor, and the anti-sealing of anti-lift is poor, and originally many cylinder iron flange forms connect, cost height, the difficulty of easily becoming rusty, uncap, shortcoming such as easy stolen.At present China does not also have a kind of product of special sewage network closed well lid for this reason, has brought certain difficulty and inconvenience for unit on probation and management.

Though the use that present construction engineering units solves airtight well lid with different ways, the defective that ubiquity is following.The carrying of combined manhole cover and the anti-ability that rises, easily aging, easy breakage can not be used.The flange join type well lid cost height of cast iron, easily stolen, easy rust, open and not put just, bring shortcomings such as difficulty to maintenance.

The utility model content

Technical problem to be solved in the utility model is, designing a kind of good leak tightness a kind of well lid easy to use props up, with overcome heaviness that present technology exists, frangible, outward appearance is outmoded, vehicle by the time noise big defective, and management maintenance and the problem such as transposing of existing well lid after solving that the product generation is multifarious and be unfavorable for building with regard to various places construction engineering units oneself.

In order to address the above problem the technical solution of the utility model is such:

A kind of sewage network well lid, comprise well lid support that is arranged on well head and the well lid that covers well head, it is characterized in that described well lid comprises a well lid frame and the well lid bottom surface that is arranged on the well lid frame, the dispersion hole that well lid frame inside is provided with ribs and is made of ribs; Described well lid is bolted to connection on the well lid support.

The mode of well lid underrun sweat soldering is connected on the well lid frame.

Be provided with sealing volume bar between well lid and the well lid support.

Beneficial effect, well lid described in the utility model is owing to have the existence of some stress dispersion hole on the well lid, stressed the obtaining of whole well lid disperseed, and bottom thermosol welding well lid bottom surface makes well lid become hollow type, on pressure is arranged, under pulling force is arranged, thereby the holding capacity of well lid increases, simultaneously because the existence of the pressure dispersion hole of well lid, the weight of well lid lowers greatly, and lowered manufacturing cost, defective such as it is big therefore to have overcome the weight that present well lid exists, and bearing capacity is little.

The specific embodiment

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

A kind of sewage network well lid comprises well lid support that is arranged on well head and the well lid that covers well head.

Referring to Fig. 1, Fig. 1 a, Fig. 1 b

Well lid 1 comprises a well lid frame 11, with the well lid bottom surface 12 that is arranged on well lid frame 1 bottom, make for polymer composite well lid frame 11 and well lid bottom surface 12, polymer composite main component ultra-high molecular weight polyethylene, well lid frame 11, has certain thickness, well lid frame 11 inside are provided with several ribs 111, ribs 111 plays the effect of support reinforcing, ribs 111 intersects to form dispersion hole 112 in length and breadth, just because of this structure, not only well lid frame 11 structures are strengthened, and have also alleviated the weight of well lid frame 11 simultaneously greatly.Well lid bottom surface 12 is welded on the bottom of well lid frame 11 by the mode of sweat soldering, and the well lid face is provided with anti-skidding lines.And well lid 1 is provided with six bolts hole 13 that are connected with the well lid support.

Referring to Fig. 2, Fig. 2 a

Well lid support 2 is arranged on the well head of sewage network, and the diameter of well lid support 2 conforms to well lid.Well lid support 2 is provided with the hole 21 of hollow out and is used to install six bolts hole 22 of well lid 1.Well lid support 2 installs when the building hoistway, and well lid support 2 also is the polymer composite identical with well lid.On well lid 1, also be provided with and be used for colluding hole 14 what well lid promoted.

Referring to Fig. 3, Fig. 3 a, Fig. 3 b

During installation, well lid 1 is placed on the well lid support 2, and well lid 1 is fixedlyed connected with well lid support 2,, between well lid 1 and well lid support 2, be provided with sealing volume bar 31 for better sealing with bolt 3.
