Description

Municipal administration well lid

Technical Field

The utility model relates to a well lid technical field specifically is a municipal administration well lid.

Background

The manhole cover is used as an important component of an urban drainage system, influences the urban beauty and bears life safety, the urban management level is checked at any time, the manhole cover is a closed object leading to the top of an access of an underground facility, plays a role in lifting the weight in the installation and layout of public facilities such as tap water, telecommunication, gas, fire protection, environmental sanitation and the like, and in recent years, along with the continuous high-speed development of the urban infrastructure construction industry of China, the number of the manhole covers is increased day by day, most of the traditional manhole covers are formed by cast iron, and comprise grey cast iron and nodular cast iron, wherein the grey cast iron is low in strength and high in brittleness, the manufactured manhole cover is heavy, the use amount is gradually reduced, the nodular cast iron is high in strength and toughness, and the manhole cover with the best mechanical property can be manufactured and is used for most of manhole covers of grades C250 and D400, but the manhole cover is also high in, The transportation and installation cost is higher, and the noise is large when the vehicle passes in the use process, in addition, the manhole cover is made of steel fiber concrete and polymer matrix composite material, wherein the toughness of the steel fiber concrete is improved compared with that of common concrete, but the steel fiber concrete still cannot be collided and impacted, and the corners are easy to damage; the polymer base or resin base composite material, especially glass fiber reinforced plastic material, can reach very high tensile strength and bending strength, and produce lighter manhole cover, but the weather resistance or ageing resistance is poor, and the bearing capacity is attenuated along with the ageing of the polymer or resin. Therefore, the utility model discloses aim at developing a novel municipal administration well lid to better satisfy the municipal needs.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem in providing a municipal administration well lid to solve the shortcoming in the above-mentioned background art.

The utility model provides a technical problem adopt following technical scheme to realize:

the utility model provides a municipal administration well lid, includes the base and inlays the lid of locating on the base, the lid is platelike structure, and the lid includes a plurality of component units, and the component unit is hollow tetrahedron structure, has all seted up the outlet on every of component unit.

The utility model discloses well nodular cast iron lid has fine intensity, toughness and plasticity, and the comprehensive properties is higher, and has fine wearability and shock attenuation nature.

The utility model discloses in, the component unit is regular tetrahedron structure. The regular tetrahedron structure has good mechanism stability and good integrity after arrangement and combination.

The utility model discloses in, the outlet is seted up in the central authorities of every face of regular tetrahedron, and the area ratio of the face of outlet area and outlet place regular tetrahedron is (0.5 ~ 0.7): 1. the water outlet within the range can ensure the self strength of the component unit while ensuring better water drainage effect.

The utility model discloses in, the lid increases progressively in proper order by the outlet area on its component unit of edge to center. The larger the area of the water outlet is, the stronger the water discharging capacity is, and the lower the self strength of the corresponding component unit is, so that the design can resist the bending moment action of the middle area of the cover body and the shearing action of the edge area, and the cover body can be prevented from being broken at the edge.

The utility model discloses in, the lid is circular lid, and the lid is followed from last to its external diameter steadilys decrease in proper order extremely down. The cover body is not easy to loosen in the base due to the inverted trapezoidal structure adopted by the cross section of the cover body, so that the cover body is more stable and reduces noise.

The utility model discloses in, the base is from last to descending its external diameter in proper order steadilys decrease. The base cross-section also designs into the structure of falling the trapezium, makes it inlay in the ground and is difficult sunken, and the plan view also has better aesthetic feeling.

Has the advantages that: municipal administration well lid, it is compared with traditional well lid, the dead weight has obtained very big reduction, has reduced manufacturing material and cost of transportation, removes ferrous material's a large amount of consumptions from, and its bearing capacity has reached the national standard of well lid, simultaneously, it has fine intensity, toughness and wearability and shock attenuation nature, the noise that produces in the use is less, has fine practicality.

Fig. 1 is a schematic structural diagram of a preferred embodiment of the present invention.

Fig. 2 is a schematic view of a connection structure of the component units according to the preferred embodiment of the present invention.

Wherein: 1. a cover body; 2. a base; 3. a member unit; 4. and a water outlet.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1, a preferred embodiment of the municipal well lid comprises a base 2 and a lid 1 embedded on the base 2, wherein the lid 1 is a plate-shaped structure, the lid 1 can be a circular, rectangular, or oval and kidney-shaped structure, the embodiment is a spheroidal graphite cast iron round plate-shaped lid as an example, the lid 1 is composed of a plurality of component units 3, as shown in fig. 2, the component units 3 are hollow regular tetrahedrons, each face of the regular tetrahedron is provided with a water outlet 4, the water outlet 4 is arranged in the center of each face of the regular tetrahedron, and the ratio of the area of the water outlet 4 to the area of the side face of the regular tetrahedron where the water outlet 4 is located is (0.5-0.7): 1, specifically, the area of the water outlet 4 on the component unit 3 of the cover body 1 increases from the edge to the center.
