Description
Technical field
The utility model relates to bridge construction field, particularly relates to a kind of headwall formula abutment.
Background technology
Abutment is positioned at bridge two ends, is supporting bridge superstructure and the building be connected with embankment.Usually, abutment comprises abutment main body and accessory structure, and abutment main body is made up of platform top, abutment body, platform cap, pinner and basis, and accessory structure is formed by boring slope and drainage system etc.
But, the problems such as the design of bridge abutment structure is complicated, cost is high, and constructional difficulties, disease are many, and later period maintenance maintenance cost is high are the problems enjoying engineer and management organization to pay close attention to always, particularly under complex hydrologic geology environment, the setting on cone slope determines the key of abutment quality often.As, in soft clay area, in order to ensure quadrant of truncated cone structural safety, often to carry out extra reinforcing to cone hillside fields base, and reinforce costly.In mountain area, because the cone slope of abrupt slope abutment is on slope, cannot take root, cone is very large, sometimes even there will be very thin cone drapes over one's shoulders on slope, is easy to like this slip brokenly, stablizing thus in order to ensure cone, usual needs cone pin on set up the retaining structure such as barricade, antislide pile, thus create constructional difficulties, cost raise and workmanship is difficult to the series of problems such as guarantee.In river cheuch area, abutment often meets with washing away of flood, although cone reduces flood passage area, cone corrodes serious by flood erosion, will threaten the safety of bridge.In addition, in order to meet the requirement of traffic and navigational clearance under bridge, quadrant of truncated cone is put slope and is restricted the situation that even can occur to arrange cone slope, thus usually needs higher, the more complicated scheme of cost to replace boring slope.
Therefore, be necessary to provide one can not only optimize bridge abutment structure design, and the headwall formula abutment that can meet corresponding function requirement is to overcome above-mentioned defect.
Utility model content
The purpose of this utility model be to provide a kind of disease few, be easy to safeguard, the low and headwall formula abutment of long service life of maintenance cost.
To achieve these goals, the utility model provides a kind of headwall formula abutment, comprise abutment main body, abutment retaining structure and a pair attached discharge structure, abutment main body comprises platform top, abutment body, platform cap, pinner and basis, abutment body is arranged on basis, platform top is arranged on the top of abutment body, the bottom of abutment body front end is located at by platform cap, pinner is arranged on platform cap, abutment retaining structure comprises headwall, rib wall and side wall, headwall be located at abutment body rear end and perpendicular to basis, rib wall compartment of terrain vertical folder is located between headwall and basis, side wall is located at the two ends of headwall, a pair attached discharge structure is symmetrically set in the two ends of headwall and each attached discharge structure comprises spilled water hole, catch basin, lateral sulcus, drain tank, Buffer Pool and ditch, spilled water hole is arranged on headwall, catch basin is arranged on the bottom of headwall, lateral sulcus is located at side coping, drain tank is arranged at the front end of side wall and is communicated with lateral sulcus, Buffer Pool is located at the bottom of side wall and is communicated with drain tank with catch basin, ditch is located at the front end of side wall and is communicated with Buffer Pool.
Preferably, headwall is surface plate and parallel with the cross section of roadbed.The contour shape of headwall is similar to the shape in the cross section of roadbed.
Preferably, headwall is made up of surface plate and the folding panel that is bent to form along surface plate two ends, and surface plate is parallel with the cross section of roadbed.Projected outline's shape of headwall is similar to the shape in the cross section of roadbed.
Preferably, be provided with settlement joint in basis, settlement joint is positioned at the junction of headwall and abutment body.
Preferably, rib wall is triangle beam slab, trapezoidal beam slab or rectangle beam slab.
Preferably, headwall and basis forms " L " font or " T " font.This structure can reduce the pressure of the roadbed filling being delivered to abutment, increases self-stability energy and structural strength.
Compared with prior art, on the one hand, the utility model by arranging headwall in the rear end of abutment main body to substitute the cone in existing abutment, thus overcomes because arranging the diseases such as maintenance difficulty that cone brings, structure durability be poor, and then reduces maintenance cost; On the other hand, headwall formula abutment of the present utility model stressed reliable, reasonable, economic, to the bridge abutment structure of highway, municipal administration, railroad bridge, particularly under complex hydrologic geology environment, the design of railway abutment has reference and reference, is also applicable to head and the tail across arranging the limited situation in cone slope because of the Clearance requirement such as traffic, navigation under bridge; Again on the one hand, the structure collectivity cost of headwall formula abutment of the present utility model is low, disease is few, for ease of maintenaince maintenance and late maintaining cost is low.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
