Abstract
A double-wall steel cofferdam for underwater low pile cap belongs to the technical field of bridge manufacturing, and is characterized in that an inner wall board and an outer wall board are fixed integrally through a box beam between the inner wall board and the outer wall board and form an inner wall and an outer wall of the cofferdam, a horizontal truss between the inner wall board and the outer wall board assists in fixing the inner wall board and the outer wall board, the box beam is supported intensively by an horizontal inner braces and vertical stay bars, cutting edges of the cofferdam are wedge-shaped, and brackets, a bottom assembly platform, lower guide frames and lower reaction frames are mounted on steel casings. The double-well steel cofferdam for an underwater low pile cap has the advantages of definiteness in stress, simple structure and capabilities of providing a better guarantee to safety of external construction environment and reducing expense in use.
Description
Technical field
The utility model belongs to the bridging technical field, is specifically related to the improvement in steel body cofferdam in a kind of water.
Background technology
In the existing bridging work progress, the low pile cap construction methods such as steel concrete casing, steel sheet-pile cofferdam that adopt in the water more, method therefor should satisfy working space needs and force request, consider that again construction is convenient feasible, in order to take into account the requirement of each side, often in work progress, waste a large amount of manpowers and constructional materials.
Summary of the invention
The purpose of this utility model is: low pile cap double-walled steel cofferdam in a kind of water is provided, and it not only can satisfy the bearing platform construction needs, and it is stressed, simple in structure to help whole system, can reduce consumption of materials.The technical solution of the utility model is: it is made up of box beam, inside panel, exterior panel, the perpendicular rib of wallboard, horizontal truss, horizontal ring flat-plate, horizontal inner support, vertical strut, sword pin, filling pipe.
Between inside panel, exterior panel, obtain overall fixed by box beam, form cofferdam inwall, outer wall, assist solid between inside panel, the exterior panel by horizontal truss, by horizontal inner support and vertical strut the box-shaped wall body is added strong supporting, the sword pin is a wedge shape, bracket, coxopodite platform for lining is installed on the steel casing, transfers leading truck, is transferred reaction frame.
The beneficial effects of the utility model are: low pile cap double-walled steel cofferdam system is stressed clear and definite, simple in structure in the water, and its utilization can make construction external environment condition safety obtain better guarantee, the reduction expense.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model left view;
Fig. 3 is the front view that adopts the utility model construction;
Fig. 4 is the left view of Fig. 3.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the 1st, box beam, the 2nd, inside panel, the 3rd, exterior panel, the 4th, wallboard erects rib, and the 5th, horizontal truss, the 6th, horizontal ring flat-plate, the 7th, horizontal inner support, the 8th, vertical strut, the 9th, sword pin, the 10th, filling pipe, the 11st, the steel casing, the 12nd, transfer leading truck, the 13rd, transfer reaction frame, the 14th, crane barge, the 15th, the soil body.
One of its structure of the utility model is to form the wall body structure by inside panel, exterior panel and shaped steel to satisfy dash and force request, forms several block structures and satisfies the assembly unit needs.
One of its structure of the utility model is by horizontal inner support and vertical strut the box-shaped wall body to be added strong supporting.
One of its structure of the utility model is that the sword pin is done wedgewise and realized more easily inserting the soil body.
According to design drawing processing and fabricating steel member, be processed into some box ancient piece of jade, round, flat and with a hole in its centre bodies and sword pin 9 steel cofferdam piece spares with box beam 1, inside panel 2, exterior panel 3, the perpendicular rib 4 of wallboard, horizontal truss 5, horizontal ring flat-plate 6, transport to on-the-spot spelling with automobile and barge then.After drilling construction is finished, bracket, coxopodite platform for lining are installed on steel casing 11, transfer leading truck 12, transferred reaction frame 13.Utilize crane barge 14 that coxopodite steel cofferdam piece spare is installed, transfer by transferring reaction frame 13 integral body.The coxopodite entry is after floating, and piecemeal, merogenesis are installed residue steel cofferdam piece spare, steel cofferdam sinkings of pouring water, and sword pin 9 implantations, suction mud makes sword pin 9 sink to design attitude in the cofferdam then.If water level is lower than river in the cofferdam, by filling pipe 10 automatic water supplements.Build under water the back cover concrete and treat that it reaches after the intensity and draw water in the steel cofferdam, horizontal inner support 7 and vertical strut 8 are installed downwards successively, gradation is with horizontal inner support 7 and 8 dismountings of vertical strut bearing platform construction is finished after.
