Abstract
The utility model discloses a kind of manhole cover, comprise manhole cover body, described manhole cover body is circular square oval or irregular shape, described manhole cover body is provided with multiple drain holes, and described multiple drain holes are uniformly distributed on the circle in the center of circle at the center taking manhole cover body.The utility model is ensureing under the stressed bearing function prerequisite of manhole cover road, increase road surface quick water-discharging function, displacement is large, simple in structure, can reduce fast waterlogging phenomenon, reduce road surface floods people and cause the person or other security incidents for opening manhole cover quickening draining.
Description
Technical field
The utility model relates to building materials field, relates in particular to the well lids such as a kind of municipal administration, electric power, the communications field.
Background technology
Manhole cover is widely used in the places such as road, community, park, parking lot, square, its Main Function is as the open hole that checks that circuit uses for the storm sewer of below, sewage conduct, telecommunication line, power pipeline etc., people conveniently goes down and safeguards and overhaul, general 25 ~ 50 meters of left and right.In recent years due to large area construction, green coverage reduces, entirety amount of precipitation increases, rainwater deposits on road surface, in the time that surface gathered water amount is many, for Accelerating Removal ponding, usually the well lid on road surface is raised and placed roadside, accelerate to clear away the collected water with this, many times rainwater comparison, the well lid mouth flowing water personnel that cause have been involved in below in pipeline, or owing to being negligent of nurse, after ponding is discharged, forget well lid is reverted to original position, and well head is exposed on road surface, easily cause potential safety hazard, especially at night, pilot's line of vision is unclear or hurry on a journey because being eager, be easy to be embedded.
Application number is that the Chinese patent that 200720026834.5 patent names are " drainage manhole cover " discloses a kind of drainage manhole cover, below well lid main body, be provided with tank, tank is connected with well lid main body by connector, at the center of well lid main body opening, opening part has a disk, is connected with the floating block being arranged in tank below disk.Although this patent can be accelerated drainage speed, built on the sand, and displacement is little for complex structure.
Application number is that 201220619917.6 patent names disclose a kind of catch basin cover for " a kind of catch basin cover ", comprise framework and band drain, this band drain is embedded in framework, on band drain, be provided with multiple drain holes, and around framework, being provided with groove, framework and band drain adopt the sponge of hard bubbling to make.This catch basin cover is not the well lid using on manhole, its form of structure and existing concrete drainage grill structural similarity, it is larger that drain hole accounts for whole surface area, can not carry load, because adopting, material should steep sponge, can only use at greenbelt or the place that is not subject to load force, and the endurance quality of material and rising-heat contracting-cold performance obvious, can not be high temperature resistant, application life is poor, and due to lightweight, the easy unstability of structure, easy generation is inclined to appearing in one's mind and is resembled.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of road surface quick water-discharging function, displacement manhole cover large, simple in structure of increasing is provided, and reduces waterlogging people and causes the person or other security incidents for opening well lid.
Above-mentioned purpose of the present utility model is achieved by following technical solution:
A kind of manhole cover, comprise manhole cover body, described well lid body is circular square or oval etc. irregularly shaped, and described manhole cover body is provided with multiple drain holes, and described multiple drain holes are uniformly distributed on the circle in the center of circle at the center taking well lid body.
The utility model arranges multiple drain holes and carrys out capable of increasing water discharge capacity, and rounded being uniformly distributed, and drainage speed is accelerated.Described drain hole can be arbitrary graphic.
Further, described drain hole is more than 4.Total cross-sectional area of described multiple drain holes be not more than well lid body cross-section long-pending 20%.The equivalent diameter of described drain hole is 20 ~ 100mm.Described drain hole can be arbitrary graphic.
Further, be also provided with multiple open holes.Described open hole is 2, and described open hole is taking the center of well lid body as symmetric points are symmetrical arranged.Open hole is for the lifting of well lid.
Described manhole cover body surrounding inner edge, drain hole inner edge and open hole inner edge are all with gradient.Described gradient is 3 ~ 7 degree.
Described manhole cover body surface is provided with anti-skid design.Described anti-skid design has strengthened the frictional force of well lid body surface, has anti-skidding effect.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model, by multiple drain holes being set on manhole cover body and being uniformly distributed on the circle in the center of circle taking the center of manhole cover body, increases road surface quick water-discharging function; The utility model is simple in structure, can reduce waterlogging people and cause the person or other security incidents for opening well lid.
