Abstract

The utility model discloses an asphalt concrete composite well lid, and belongs to the field of underground pipeline well lids. The asphalt concrete composite well lid comprises a well lid body consisting of a reinforced concrete layer and an asphalt concrete layer composite with and fixed on the reinforced concrete layer; the size of the asphalt concrete layer is smaller than that of the reinforced concrete layer; inwardly-retracted steps are upwardly formed on the vertical planes of the layers; at least a pair of symmetrically-arranged lifting hooks for hoisting the well lid is pre-buried in the step on the reinforced concrete layer; a water stopping belt is embedded at the periphery of the asphalt concrete layer; grooves are formed in the positions where the water stopping belt is in contact with the lifting hooks; the lifting hooks are embedded in the grooves of the water stopping belt. The asphalt concrete composite well lid has a simple structure, is convenient to use, can increase ride comfort of motor vehicles during driving, improves driving comfort, and has effects of water stopping, shock absorption, sound absorption and displacement prevention.

Description

A kind of bituminous concrete combined manhole cover

Affiliated technical field

The utility model relates to a kind of bituminous concrete combined manhole cover, belongs to the underground pipeline engineering field.Be mainly used in the well lid of catch-basin in network of underground, sink hole, heating power well, strong and weak electricity well etc.

Background technology

At present, on the road in city, parking lot, square and other places, all be provided with in a large number the well lid of some network of underground, the material of most well lids is concrete materials, and its hardness is larger, when vehicle from top through out-of-date, the driving vibration is large, the driving irregularity.Through long-term, use, well lid often there will be phenomenons such as gnawing limit, displacement, affects the durability that well lid is used.

Summary of the invention:

In order to overcome the deficiency of existing well lid, the utility model provides a kind of bituminous concrete combined manhole cover, and this well lid has certain pliability, and the ride comfort of driving is provided; Simultaneously, this well lid has certain cushioning effect, has damping, absorbs sound, prevents the effect of displacement, improves its useful life longevity.

The utility model solves the technical scheme that its technical problem adopts: a kind of bituminous concrete combined manhole cover, comprise the well lid body, described well lid body comprises reinforced concrete floor and is composite and fixed at the asphalt concrete layer above it, asphalt concrete layer is less than reinforced concrete floor, forms upwards internal withdraw type step on facade; On the step of reinforced concrete floor, be embedded with for lifting by crane symmetrically arranged at least one pair of suspension hook of well lid; Be embedded with waterstop in the asphalt concrete layer surrounding, waterstop leaves groove type in the position contacted with suspension hook, and suspension hook is embedded in the waterstop groove.

Described reinforced concrete floor is fixedly connected with by connector with the asphalt concrete layer above being composite and fixed at it, and connector is anchored in reinforced concrete floor, and upwards extend in asphalt concrete layer.Increase anchoring and the globality of reinforced concrete floor and asphalt concrete layer.

Described connector is bar dowel, flat nail or U-shaped reinforcing bar.

Described waterstop is variable cross-section, in the ，Qi cross section, position do not contacted with suspension hook, is rectangle, and in the place contacted with suspension hook, the waterstop cross section is groove type, and suspension hook is embedded in the waterstop groove.

The beneficial effects of the utility model are: this utility model is simple in structure, easy to use, can increase the ride comfort of motor vehicle running, improves the driving comfort, has sealing, damping, absorbs sound, prevents the effect of displacement.This well lid can be made shades of colour, is conducive to beautifying of environment.

The accompanying drawing explanation:

Fig. 1 is sectional view of the present utility model;

Fig. 2 is the utility model top view.

In figure: 1. reinforced concrete floor; 2. asphalt concrete layer; 3. connector; 4 suspension hooks; 5. waterstop.

The specific embodiment:

Below in conjunction with accompanying drawing, the utility model is further illustrated.

As depicted in figs. 1 and 2, the utility model comprises reinforced concrete floor 1, asphalt concrete layer 2, connector 3, suspension hook 4 and waterstop 5.Be asphalt concrete layer 2 above reinforced concrete floor 1, between reinforced concrete floor 1 and asphalt concrete layer 2, connector 3 arranged, asphalt concrete layer 2 radius when making is less than approximately 5～8cm of reinforced concrete floor 1, forms upwards internal withdraw type step on facade.On the step of reinforced concrete floor 1, be embedded with for lifting by crane the symmetrically arranged a pair of suspension hook 4 of well lid; Be embedded with waterstop 5 in the asphalt concrete layer surrounding, waterstop leaves groove in the position contacted with suspension hook, and suspension hook is embedded in the waterstop groove.

Reinforced concrete floor is fixedly connected with by connector 3 with asphalt concrete layer, and connector is U-shaped reinforcing bar; U-shaped Bar Anchorage, in reinforced concrete floor, and upwards extend in asphalt concrete layer.Increase anchoring and the globality of reinforced concrete floor and asphalt concrete layer.

Be embedded with waterstop 5 in asphalt concrete layer 2 surroundings, waterstop is variable cross-section, in the ，Qi cross section, position do not contacted with suspension hook, is rectangle, and in the place contacted with suspension hook, the waterstop cross section is groove type, and suspension hook 4 is embedded in the waterstop groove; During production, waterstop is anchored on the reinforced concrete floor step in advance, in the contact process of well lid and walling crib, plays cushioning effect, alleviates shaking force, has eliminated noise, and what prevented well lid gnaws the limit phenomenon.

Suspension hook 4 is made by reinforcing bar, and they are embedded in respectively on the position of reinforced concrete floor step symmetry, for lifting by crane well lid in advance.

The shape of well lid is not limited to circle, can be also the various shapes such as square, rectangle, shape changeable, buttferfly-type.
