Undisturbed soil is finally used to be backfilled to earth's surface；S2: straight wall is constructed, and uses construction of diaphragm wall technique, excavates straight wall foundation ditch, colligation
Straight wall steel reinforcement cage is also transferred to straight wall foundation ditch, reserved standard straight wall lower end steel reinforcement cage with baseplate reinforcing bar cage level overlap joint and
With standard straight wall and the protection straight wall upper end steel reinforcement cage of roof steel bar cage level overlap joint, pour straight wall concrete；S3: top board foundation ditch
Excavation, the soil body above excavation top board forms top board foundation ditch, subsequently the place of top board foundation ditch is carried out cure process；S4: top board
Construction, colligation roof steel bar cage in top board foundation ditch, and overlap with straight wall steel reinforcement cage, installation form, casting concrete forms steel
Reinforced concrete top board；S5: soil excavation, after concrete roof intensity reaches design requirement, between excavation top board and straight wall
The soil body, carries out place cure process subsequently；S6: construction of bottom plates, colligation baseplate reinforcing bar cage also overlaps with standard straight wall steel reinforcement cage, waters
Build concrete and form reinforced concrete floor, finally backfill top board foundation ditch, complete frame bridge construction.
The beneficial effects of the utility model:
(1) the frame bridge simple in construction designed by this utility model, construction technology is the most controlled, it is not necessary to large-scale excavation is opened
Dig, short construction period, less to the traffic impact of job location, it is under a kind of city intersection being applicable to heavy traffic
Wear frame bridge structure.
(2) frame bridge designed by this utility model construction method use first construct straight wall, again construct top board, finally execute
The mode of work base plate, it is to avoid the large-scale excavation excavation in the construction of original frame bridge, simplifies construction technology, greatly reduces
Construction costs cost, has obvious economic benefit.
Accompanying drawing explanation
Fig. 1 is the frame bridge structural representation of hysterology of the present utility model construction；
Fig. 2 is the step schematic diagram of the hysterology construction of frame bridge of the present utility model；
In figure: straight wall 1 (standard straight wall 11, protects straight wall 12, protects straight wall anchoring section 12a), top board 2, base plate 3.
Detailed description of the invention
In order to be better understood from the technical solution of the utility model, new to this practicality with specific embodiment below in conjunction with the accompanying drawings
Type is described in further detail.
As it is shown in figure 1, the frame bridge structure of a kind of hysterology construction, including straight wall 1, top board 2, base plate 3 be arranged at the end
Reinforcing foundation pile in basis below plate 3, described straight wall 1, top board 2 and base plate 3 are reinforced concrete structure, described reinforcing foundation pile
For circular steel reinforced concrete foundation pile, described straight wall 1 is the monoblock type knot that standard straight wall 11 and protection straight wall 12 are spaced composition
