Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 is that well lid, 2 is that expanded type walling crib, 3 is that pit shaft, 4 is that branch's piece, 5 is that bottom backing plate, 6 is the well head road surface.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Like Fig. 1, the integrated manhole of a kind of anti-settling comprises well lid 1, it is characterized in that said well lid 1 is arranged in the expanded type walling crib 2, expanded type walling crib 2 be embedded in the pit shaft 3 of well head road surface below 6 and be connected to an integral body.
Manhole is as the attached minor installation in road surface, and its based process is generally for paying attention to, thus the base stress that makes manhole greater than road surface, roadbed with degree of depth stress, the substrate sedimentation is greater than roadbed subsidence, well head sinks.Will be appreciated that; Manhole is as the independent structures thing, and what bear is whole wheel impacts load, so reach the wheel load effect to several times of overload; And compare with the bridge construction basis; The substrate buried depth of manhole is much littler than bridge foundation, and is that single manhole is stressed alone, and its basic operating mode is poorer than the basic operating mode of bridge construction; So should manhole based process and bridge construction based process be put on an equal footing, to guarantee that manhole substrate load stress is with consistent with the base stress of degree of depth subgrade and pavement.
The utility model uses and expands disc type well seat and bifurcated shaft structure, and manhole and road surface are integrally formed.
Traditional walling crib seat and well bore; The walling crib seat is a circle ring column; The impact force of wheel is directly passed to the vertical shaft body after putting on well lid, walling crib seat, and the higher road structure of intensity is bearing load not, in vehicular impact power with repeatedly under the action of long-term load; Add the well bore deadweight, then must be with the sinking that causes manhole.For reducing the effect of wheel impacts power to well bore, the utility model adopts the bifurcated pit shaft and expands disc type walling crib holder structure,
Branch's piece of the utility model can adopt prefabricated cement concrete branch's piece or steel concrete branch dish; Expand disc type walling crib seat and can adopt reinforced concrete prefabricated structure; Walling crib seat expansion dish diameter should be bigger than pit shaft; Ying Yousan/one is held in the supercrust, makes the suffered traffic load of walling crib seat pass to supercrust through expanding disc portion
The wheel load that puts on the well lid is transmitted to wheel load in each deck of road surface roadbed through expanding disc type walling crib seat and bifurcated well bore one by one, and unloading one by one enlarges lifting surface area, reduces manhole substrate basis stress.Road surface base course and well body are stressed jointly, make manhole well bore and well head road surface part formation on every side overall structure, and manhole bears traffic load no longer separately, thereby the anti-sedimentation capacity of manhole is improved.
The utility model uses concrete prefabricated building block to build pit shaft.Because of the crisp mashed settlement issues that causes of loam brick material corrosion can be handled through the method for improving the well bore building material; Developed countries such as Europe, U.S.A, day build material with regard to manhole already and reform; As use precast concrete segment formula, prefabricated reinforced concrete pin-connected panel, the bottom is cast-in-place with top precast assembly convolution etc., common ground is that all the well bore material uses cement concrete product to substitute traditional loam brick.Its advantage can be avoided firing in the loam brick process consumption to the soil and the energy, realizes that the rapid construction of pipeline assemblingization needs, the intensity and the durability of control concrete clamp dog, thus avoid rotting the well head sedimentation that causes because of well bore material corrosion shortcake.
