Description
The present invention relates to the present invention relates to hydraulic engineering technical fields, it is specifically related to a kind of combined type cofferdam.
Background technology
Cofferdam refers in hydraulic engineering construction, to build permanent water conservancy projects, the provisional building enclosure built.Its
Effect is to prevent water and soil from building position into building, so that in cofferdam internal drainage, excavation pit builds building.One
As be mainly used in waterwork, except as formal building a part in addition to, cofferdam is generally removed after being finished.Cofferdam height
Higher than the peak level being likely to occur in the construction time, in bridge foundation construction, when bridge pier, stylobate plinth be located at earth's surface water level with
When lower, built according to local material into various forms of earth banks；Water compared with depth and the larger river of flow velocity can be used pile plank or
Steel sheet pile（Individual layer or bilayer）Cofferdam and much meeting double-layer thin wall steel cofferdam.The effect in cofferdam not only can with waterproof, enclose water, but also
The crater wall of foundation pit can be supported.In sewage disposal operational process, needs are frequently encountered in steel reinforced concrete pool and clear up part
Region to install or maintenance test equipment, increases the Inlet and outlet water nozzle of pond lower part, repair regional area of percolating water etc. this
Shi Ruguo falls water remaining in pond, mud complete liquidation, then needs to expend many human and material resources and time, sometimes these
Remaining sewage, sludge are cleaned to outside pond, it is also possible to cause secondary pollution.
Invention content
For overcome the deficiencies in the prior art, the present invention has made a kind of combined type cofferdam, with the rectangular weir plate group of four block lengths
Rectangle cofferdam is synthesized, is cleared up for the part for the treatment of tank, and water in cofferdam and mud do not go out processing pond, will not cause two
Secondary pollution.
The technical solution adopted in the present invention is：A kind of combined type cofferdam, including the first weir plate, the second weir plate, riser, bottom
Plate, manual jackscrew, nut, frid screw, angle steel weir notch, the first weir plate are both provided with for two end faces of common weir plate and weir plate
The round tenon of multiple protrusions, the second weir plate are provided at both ends with weir plate slot, and the shape in cofferdam is rectangle, left and right two faces in cofferdam
It is made of the first weir plate, former and later two faces are made of the second weir plate, two ends of the first weir plate and the weir plate slot of the second weir plate
In be coated with one layer of waterproof material, the tenon of the first weir plate end be inserted into the weir plate slot of the second weir plate and pass through angle steel weir notch and
Frid screw is fixed, embedded in the gap of the engaging portion of the inner surface of the first weir plate and the second weir plate inner surface to be arranged parallel to the
The riser of one weir plate simultaneously passes through screw and is fixedly connected with weir plate, and bottom plate is arranged on the bottom in rectangle cofferdam and passes through screw and weir plate
It is fixedly connected, the lower end of weir plate is coated with one layer of waterproof material, and four vertex in rectangle cofferdam are equipped with angle steel weir notch, angle steel weir
One end face of slot is fixed at by frid screw on the second weir plate outer surface, another end face is pushed up by nut and manually
Silk is fixed on the outer surface of the first weir plate.
Preferably, the bottom plate and riser are all made of the rubber slab of 5mm thickness.
Preferably, screw is fixed at an end face of angle steel weir notch, and manual jackscrew and nut are fixed at angle steel
On another end face of weir notch.
Preferably, weir plate is made of stainless steel and weir plate surface is provided with waterproof layer.
Preferably, weir plate slot is less than the diameter of weir plate slot for the diameter of circular weir board slot and tenon.
Compared with prior art, the beneficial effects of the invention are as follows：By using the rectangular weir plate composition cofferdam of 4 block lengths, wherein
The both ends for having 2 pieces of weir plates are respectively equipped with weir plate slot and manual jackscrew, and in addition the two of two pieces of weir plates end face is both provided with multiple convex
The round tenon risen, is inserted into circular weir board slot and and being used cooperatively 4 pieces of weir plate groups by manual jackscrew and nut respectively
Rectangle cofferdam is synthesized, round tenon and circular weir board slot are coated with one layer of waterproof material, and bottom plate and riser are by rubber slab system
Into so that the water resistance of entire combined type cofferdam structure is more preferable, and regional area in pond can be cleared up using this combined type cofferdam,
And water in cofferdam and mud do not go out processing pond, save a large amount of human and material resources and time, nor can cause secondary dirt
Dye.
