Abstract
The utility model relates to an assembled type cofferdam. The cofferdam comprises a steel pipe rack with a trapezoidal cross section; the steel pipe rack is formed by connecting a plurality of steel pipes via connecting pieces; a traffic bridge plate is laid on the top face of the steel pipe rack; a horizontal front plate is arranged on the lower part of a steel pipe rack side face on the lower part of a cofferdam body; the top end of the front plate is connected with a seepage-proof cloth film which covers the front plate and the steel pipe rack side face on the lower part of a cofferdam body; and the seepage-proof cloth film and the front plate are connected with a stay rope. The cofferdam is assembled in a way that the steel pipes are transported near an engineering place, are assembled according to a design paper, are hoisted into a river in sequence, and are spliced, and after the bridge plate is laid, the welded seepage-proof cloth film is laid on the upper part of the cofferdam body, so construction for the cofferdam is finished. The cofferdam is practical, environment-friendly and convenient and quick to construct, and engineering investments are saved.
Description
Technical field
The utility model is a kind of hydrotechnics, is mainly used in the cofferdam technology in construction, is a kind of assembly type cofferdam specifically.
Background technology
At present, in hydraulic engineering, need to build cofferdam time, be all generally to cut the earth, build earth rock cofferdam, be transported to construction place by native stone, utilize the construction equipments such as bulldozer to pile minor dam in echelon, after engineering construction finishes, recycling excavator is removed, and is transported to spoil area.Its major defect has:
1, need to fetch earth and spoil ground;
2, severe water and soil erosion;
3, difficult quality guarantee;
4, speed of application is slow;
5, invest high.
Summary of the invention:
The utility model, for overcoming above-mentioned the deficiencies in the prior art, provides both practicality and environmental protection of one, again quick, cheap assembly type cofferdam.
For achieving the above object, the utility model adopts following technical scheme:
A kind of assembly type cofferdam, comprise that the section being connected to form by connector by some steel pipes is trapezoidal steel pipe frame, on described steel pipe frame end face, be equipped with access bridge plate, be provided with the header board of level in the bottom, steel pipe frame side of upstream, cofferdam, header board top connects antiseepage cloth film, and antiseepage cloth film covers on header board and the steel pipe frame side in upstream, cofferdam; On antiseepage cloth film and header board, be connected with stay cord.
Described steel pipe frame bottom is connected with some pitch sleepers.
Described front front edge of board is fixed by holdfast.
Assembling of the present utility model and method for dismounting be, assembles near steel pipe is transported to project site, forms steel pipe frame, and pitch sleeper, holdfast and header board are installed, folding header board, then, lift in order in river, and splice, lay after traffic bridge plate, the antiseepage cloth film having welded is hung on to header board top, lay after header board, antiseepage cloth film is layed on upstream, cofferdam and header board, and simultaneously, fastens stay cord cofferdam construction and complete.
When dismounting, pull stay cord, pack up header board and antiseepage cloth film, and be transported on riverbank, traffic bridge plate is removed in segmentation, and steel pipe frame is winched to riverbank together with pitch sleeper and holdfast, and decomposes and remove, and cofferdam steel pipe and antiseepage cloth are pulled down and transported warehouse back.
The beneficial effects of the utility model:
1, there is significant economic benefit.
2, environmental protection, soil erosion is few.
3, cost is low, and speed of application is fast, and easy-maintaining is easy to install.
Accompanying drawing explanation
Fig. 1 is that the utility model uses schematic diagram;
Wherein, 1. steel pipe frame, 2. antiseepage cloth film, 3. traffic bridge plate, 4. pitch sleeper, 5. holdfast, 6. stay cord, 7 header boards.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Assembly type cofferdam, comprise that the section being connected to form by connector by some steel pipes is trapezoidal steel pipe frame 1, on described steel pipe frame 1 end face, be equipped with access bridge plate 3, steel pipe frame 1 bottom, side in upstream, cofferdam is provided with the header board 7 of level, header board 7 tops connect antiseepage cloth film 2, and antiseepage cloth film 2 covers on header board 7 and 1 side of the steel pipe frame in upstream, cofferdam; On antiseepage cloth film 2 and header board 7, be connected with stay cord 6.Steel pipe frame 1 bottom is connected with some pitch sleepers 4.Header board 7 front ends are fixing by holdfast 5.
Assembling of the present utility model and method for dismounting be, steel pipe is transported near project site, assembles by design drawing, form steel pipe frame 1, and pitch sleeper 4, holdfast 5 and header board 7 are installed, folding header board 7, then, lift in river in order, and splice, lay after traffic bridge plate 3, the antiseepage cloth film 2 having welded is hung on to header board 7 tops, has laid after header board 7, antiseepage cloth film 2 is layed on upstream, cofferdam and header board 7, and simultaneously, fasten stay cord 6 cofferdam constructions and complete.
When dismounting, pull stay cord 6, pack up header board 7 and antiseepage cloth film 2, and be transported on riverbank, traffic bridge plate 3 is removed in segmentation, and steel pipe frame 1 is winched to riverbank together with pitch sleeper 4 and holdfast 5, and decomposes and remove, and cofferdam steel pipe and antiseepage cloth are pulled down and transported warehouse back.
