Description
Technical field
The utility model relates to the road well lid of urban operating mechanism, is used for sealing the sewer well head.
Background technology
At present, the following well of installing on road, instrument well, catch pit, electric power well, gasser etc. generally adopt well lid walling crib mode, walling crib and ground to install, and well lid cooperates installation with walling crib.Because iron well lid walling crib especially well lid is very easy to be stolen by the lawless person, and the well of having lost well lid is replenishing under the untimely situation of well lid, be very easy to traffic accidents such as damaged vehicle and pedestrian's tumble injury take place, even injure people's the security of the lives and property.In order to address this problem, people have invented nonmetal well lid walling crib, though solved theft problem, but this well lid walling crib adopts concrete and plastic production usually, its intensity, toughness, life-span all do not reach the technical requirements of manhole walling crib, therefore can not access effectively and apply.Normally used manhole all is a flat pattern, belongs to plank frame.Because its shape is flat shape, when being rolled, lid will bear total weight, carries little, not withstand voltage, broken easily comparatively speaking; And after the fragmentation, people's car jolts through out-of-date, causes inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, the plunger type well lid of design science.
The operating principle of plunger type well lid:
After well lid is under pressure, press down (as the plug of thermos formula) with plunger type, and the back side is with bow bridge form, bow weight supports the pressure that reduces from the top, simultaneously with gravity with horizontal transfer mode uniformly to around pass to high elastic rubber pad (as the rail beam), the bullet pad will reduce pressure, the gravity after the damping and pass to well seat and roadbed in a horizontal manner, three (pressure energetically, the bow support force, elastic force) ingenious combination has constituted simply the durable plunger type well lid of resistance to compression.
The characteristics of plunger type well lid:
Sturdy and durable, press mashedly, all vehicles of producing of China comprise excavator now, the original place rotation is pressed mashed, this is existing well lid, (iron, resin, macromolecule, magnesium stone acupuncture needle) etc., kind can't with plunger type well lid opinion than.
Be not afraid of and steal: because this well lid is a concrete material, basic nothing stealing is worth.
Cost is low: total cost 50-70 unit/cover, any material well lid all can not do.
Attractive in appearance, surface layer is colorful, and how spray to cast resin-bonded mastic, light grind (can do fluorescence coating).
Simple in structure: common bricklayer can be made, and fabrication and installation on the spot are very easily universal.
Environmental protection: do not prize lid, noiselessness does not have secondary pollution.
Service time is long: weather resistance is tens times of organic well lid, can be same all the time with roadbed.
Back of the body capping has three kinds of form of structure: the bow beam type, and tortoise lid formula, flat, can according to circumstances regulate thickness, weight, supporting capacity arbitrarily.
The difference of plunger type well lid and traditional well lid:
1, traditional well lid is a plank frame, and this well lid is a pylon formula structure.
2, traditional well lid is vertical pressurized, and this well lid is to give well seat and roadbed weight transfer in a horizontal manner.
3, traditional well lid is to burst apart to subside when gravity overloads, and the same pressure more with plug of thermos of plunger type well lid is tight more, and anti-pressure ability is extremely strong.
4, high-elastic rubber pad, cage separates when playing damping, decompression with unlatching.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of plunger type well lid comprises well lid, well seat, it is characterized in that: described well lid, well seat are reinforced concrete construction; Described well lid profile is the plunger shape, and it is configured to: the upper surface of described well lid, well seat is the plane; The lateral edge of described well lid is divided into three parts, and top is vertical edge, and the middle part is interior inclined plane, and the bottom is vertical edge, constitutes the plunger type shape that top is big, the bottom is little; The lateral edge correspondence of described well seat be divided into three parts, top is vertical edge, the middle part is the flare inclined-plane, the bottom is vertical edge, ring encircles little shellring shape greatly, down on the formation; The lateral edge shape of described well lid and well seat, size are mated mutually;
Reinforcing bar bow bridge is set in the structure of described well lid bottom, and described reinforcing bar bends the anti-arc shape that is shaped as of bridge, and described reinforcing bar bow bridge is made of two reinforcing bars, and described well lid is provided with two reinforcing bars bow bridges, is crossed as crosswise; Described reinforcing bar bow bridge top is provided with reinforcing rib, the radial distribution of described reinforcing rib; The two-layer up and down circular reinforcing bar of a circle that respectively is provided with in reinforcing bar bow bridge kink inboard of described well lid;
The circular reinforcing bar of three circles is set in the structure of described well seat, and the upper strata is provided with a circle, lower floor's outer setting one circle, and lower interior part is provided with a circle; The circular reinforcing bar of described three circles is fixed by annular dowel;
The soffit of described well lid is an intrados, and the reinforcing bar bow bridge of its arc and structure is complementary; The angle of intrados is the 3-10 degree;
Between the joint portion of described well lid, well seat resilient rubbber cushion is set.
The existing effect that slows down vibrations and pressure of this pad also has sealing function, has formed the sealing system that self compresses, and prevents drainage.When opening simultaneously, convenient well lid separates with the well seat.
