Abstract

The utility model provides a novel concrete well lid, well lid in concrete well lid support, the outer well lid of concrete and concrete, concrete well lid support adopts the recycled concrete material to pour and fixes on the wall of a well, has cylindrical recess on it, be ball collar type spatial structure in the middle of the outer well lid of concrete, be cylindrical arch all around, the well lid has the circular port on it in the concrete, link together through bolt and concrete support, the utility model discloses make the outer well lid atress of concrete even, difficult emergence is turned on one's side or uniform settlement not, keeps the evenness of road surface, through its vertical bearing capacity of space ball arch structure increase, improves the compressive capacity of well lid, lightens the water level and to the impact of the outer well lid of concrete when too big, prevents that the outer well lid of concrete from being washed away, prevents still under the circumstances of the outer well lid disappearance of concrete that the pedestrian falls into to lead to the fact the damage in the well.

Description

A kind of new concrete well lid

Technical field

The utility model relates to a kind of new concrete well lid, is applicable to the various inspection shaft such as water, manhole under urban road.

Background technology

Traditional inspection shaft adopts cast iron materials mostly, for cast iron materials because well lid is that overall cast iron is formed, Loss is serious, the lower well of well lid is not had to have a strong impact on the safety of vehicular traffic and pedestrian, so that often there is the generation of traffic and casualties's accident, the well lid design scheme adopted at present, various as main force way internal construction to bear moment of flexure, compressive strength and the rigidity of its well lid are lower, and supporting capacity is poor, and cost of manufacture does not possess advantage.

Utility model content

The utility model provides a kind of new concrete well lid to make well lid uniform force, not easily there is rollover or differential settlement, keep evenness of road surface, its vertical bearing capacity is increased by Spatial Sphere arch structure, improve the anti-pressure ability of well lid, alleviate water level excessive time impact to well lid, prevent well lid to be flushed away, when also preventing manhole cover loss, pedestrian falls in well and causes damage.

For achieving the above object, the utility model adopts following technical scheme: a kind of new concrete well lid, comprise well lid in concrete manhole cover bearing, the outer well lid of concrete and concrete, described concrete manhole cover bearing employing regeneration concrete material is built and is fixed on the borehole wall, it has cylinder shape groove, and be ball collar type space structures in the middle of the outer well lid of described concrete, surrounding is cylindrical protrusions, in described concrete, it has circular port to well lid, is linked together by bolt and concrete bearing.

Above-mentioned concrete manhole cover, its feature is: the cylinder shape groove of described concrete manhole cover bearing 1, for supporting the cylindrical protrusions of the outer well lid 2 of concrete, makes the outer well lid uniform force of concrete, not easily rollover or differential settlement occurs, keep evenness of road surface.

Above-mentioned concrete manhole cover, its feature is: the outer well lid 2 of described concrete, using Spatial Sphere arch structure as obvious mechanical characteristics, increases its vertical bearing capacity by the coordinative role of space structures, improves the anti-pressure ability of well lid.

Above-mentioned concrete manhole cover, its feature is: in described concrete, well lid 3 has circular port, and in concrete, well lid 3 is linked together by bolt 5 and concrete manhole cover bearing 1.

The beneficial effects of the utility model are: make use of effective bearing mode of ball collar and the high mechanical characteristic of concrete material compressive strength, adopt space structures to replace plane structure simultaneously, there is the coordinative role of space carrying, by improving the height of arch, well lid can be made to have higher supporting capacity, because concrete material is heavier, special equipment can be adopted to carry out construction and installation or maintenance, this well lid does not possess higher economic worth, adds that weight is comparatively large, prevents pilferage behavior well.Simultaneously, the cylindrical protrusions of the cylinder shape groove of concrete manhole cover bearing and the outer well lid of concrete is stuck, make the outer well lid uniform force of concrete, not easily there is rollover or differential settlement, keep evenness of road surface, in concrete well lid by bolt and concrete manhole cover bearing be firmly connected can alleviate water level excessive time impact to the outer well lid of concrete, prevent the outer well lid of concrete to be flushed away, when also preventing concrete outer manhole cover loss, pedestrian falls in well and causes damage.

Wherein, 1-concrete manhole cover bearing, the outer well lid of 2-concrete, well lid in 3-concrete, 4-drain hole, 5-bolt.

Detailed description of the invention

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

Fig. 1 and Fig. 2 shows detailed description of the invention of the present utility model: concrete manhole cover bearing 1 is built with regeneration concrete material and is fixed on the borehole wall, it there is cylinder shape groove, the outer well lid 2 of concrete is ball collar type space structures, surrounding is cylindrical protrusions, in described concrete, well lid 3 there is circular port, linked together by bolt 5 and concrete manhole cover bearing 1, the outer well lid of concrete and interior well lid have 4 circular row water holes respectively, facilitates rain drainage.

The cylinder shape groove of the concrete manhole cover bearing 1 of the utility model concrete manhole cover is for supporting the cylindrical protrusions of the outer well lid 2 of concrete, make the outer well lid uniform force of concrete, not easily there is rollover or differential settlement, keep evenness of road surface, the outer well lid 2 of concrete is using Spatial Sphere arch structure as obvious mechanical characteristics, its vertical bearing capacity is increased by the coordinative role of space structures, improve the anti-pressure ability of well lid, in concrete, well lid 3 there is circular port, linked together by bolt 5 and concrete manhole cover bearing 1, alleviate water level excessive time the outer well lid 1 of concrete is impacted, the outer well lid 1 of concrete is prevented to be flushed away, when also preventing the outer well lid 1 of concrete from lacking, pedestrian falls in well and causes damage.

Above-described is only preferred embodiment of the present utility model; be not limited to the utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
