Description
Technical field
The present invention relates to the connection and reinforced structure and discharge structure in a kind of well lid, particularly well lid.
Background technology
In recent years, with the extensive development of urban road construction, the quality problems of manhole have caused more and more
Safety problem, trace it to its cause, be on the one hand due to well lid management and responsibility of maintenance not in place, be on the other hand due to well lid
The unreasonable structure of itself, is exactly that well lid manufacturing cost is too high or feature lacks one of the reason for cause this unreasonable structure
Lose, particularly discharge structure and reinforced structure, there are a lot of schemes about manhole cover structure in the market, for example
A kind of anti-theft inspection well cover disclosed in CN105297776A (day for announcing 2016.02.03), and for example CN204940347U (bulletin
Day 2016.01.06) disclosed in a kind of inspection shaft well lid with greening function, this kind of technical scheme extends well lid itself
Feature, and possess reinforced structure, but also have ignored some problems simultaneously is exactly concrete layer can with the connection of reinforced structure
Lean on property and drain function.
Content of the invention
The technical problem to be solved in the present invention is：There is provided a kind of steel plate combination concrete filled steel tube can drainage manhole cover, concrete
With being connected firmly for reinforced structure, it is not susceptible to ftracture, intensity is high, draining is unobstructed.
Technical scheme is as follows：
A kind of steel plate combination concrete filled steel tube can drainage manhole cover, including concrete lid, concrete lid thickness direction
Divide equally, it is to pass through that the upper and lower surface of steel plate is connected with the steel cylindrical tube symmetrical with regard to steel plate, steel pipe
Wear the drain pipe on the upper and lower surface of concrete lid.Steel plate is embedded in concrete lid as one of the reinforced structure of well lid, and
Steel pipe is symmetrically welded at the upper and lower surface of steel plate, as the intermediate structure that steel plate is connected with concrete, due to steel pipe hollow, coagulation
Soil can be filled to inside which, increase contact attachment surface, and steel pipe itself can also bear bending load.Meanwhile, drain pipe is passed through
Steel pipe inner chamber, its two ends are concordant with concrete lid upper and lower surface, play a part of diversion draining.
The axis of the steel pipe is perpendicular to surface of steel plate, and the circumferential surface of steel pipe is non-close face, and breach area accounts for week
1/2 is less than or equal to the percentage ratio of the gross area.On the one hand the design of breach can alleviate steel pipe with concrete in expansion character
Stress caused by difference, reduces image, stream when on the other hand can pour into a mould in order to concrete by notched pipe deformation
Dynamic, convenient entrance steel duct.
The length of the breach is equal with steel pipe, and the sensing of the breach of many steel pipes is different, and the opening of breach is pointed to not
With the probability produced beneficial to entrance steel duct from different directions, minimizing space when concrete is poured into a mould.
The concrete lid and steel plate are disc and both central axes, and the central point with steel plate is as circle
Steel pipe is equidistantly distributed with the concentric circle of the heart.Make along concentric circle equidistantly distributed is convenient, particularly steel pipe
Welding, reduce welding cost.Central axes cause steel plate and the globality of concrete lid to strengthen.
The drain pipe is fitted with steel pipe inner wall.
The wall thickness of the steel pipe is less than or equal to 1/8 with the external diameter ratio of steel pipe.
The steel plate thickness is radially gradually thinning to edge from center along steel plate, as the force environment of well lid is mostly
Two end shears are big, and middle moment of flexure is big, and steel plate is set to the thin cross sectional shape in thick middle two ends therefore.
The through hole along steel plate central axial direction is provided with the steel plate, and concrete is realized mixing up and down by the through hole
The connection of solidifying soil, improves globality.
The steel pipe is gradually reduced to center from edge along the density of steel plate radial direction, and density here refers to steel pipe along steel plate
The number change of radial direction, the steel pipe height are radially tapered into from edge to center along steel plate.The steel pipe number density at edge
Greatly, the steel pipe density near central area is little, can so resist the Moment of zone line, the shearing of marginal area
Effect.
Can substitute with the not simple peg of steel pipe jaggy or bolt in the present invention, which is in filling effect, shearing resistance
Effect and deformation effect have prominent progress.
The present invention embedded in steel plate in concrete lid portion inside, and the symmetrical joint steel pipe of steel plate upper and lower surface, steel duct draw
Enter drain pipe, the distribution of steel pipe can according to the shape of well lid and force-bearing situation adjustment change, due to steel plate and steel pipe be conventional
Component, cost of manufacture are relatively low.The breach of steel pipe is designed to strengthen the connection with concrete, also can bear respective loads,
Reinforcing well lid intensity, drain pipe can draining on the basis of reinforced structure is not affected.
