Description
The present invention relates to hydraulic engineering technical field, be specifically related to a kind of combination type cofferdam.
Background technology
Cofferdam refers in hydraulic engineering construction, for building permanent water conservancy projects, the provisional building enclosure built.Its
Effect is to prevent what water and soil from entering building to build position, in order at cofferdam internal drainage, and excavation pit builds building.One
As be mainly used in waterwork, in addition to the part as formal building, cofferdam typically after being finished remove.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 positioned at earth's surface water level with
Time lower, build into various forms of earth bank according to local material；Can use in the river that water is relatively deep and flow velocity is bigger pile plank or
Steel sheet pile (monolayer or bilayer) cofferdam, and much can double-layer thin wall steel cofferdam.The effect in cofferdam both can waterproof, enclose water, again
The hole wall of foundation ditch can be supported.In sewage disposal running, in steel reinforced concrete pool, it is frequently encountered by needs cleaning local
Region, in order to install or maintenance test equipment, increases the Inlet and outlet water mouth of pipe of bottom, pond, the regional area etc. of maintenance percolating water this
Shi Ruguo falls water remaining in pond, mud complete liquidation, then need to expend a lot of human and material resources and time, sometimes these
Residue sewage, mud are cleaned to outside pond, it is also possible to cause secondary pollution.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention has made a kind of combination type cofferdam, by four block lengths square weir plate group
Synthesis rectangle cofferdam, clears up for the local for the treatment of tank, and water and the mud in cofferdam does not goes out to process pond, does not results in two
Secondary pollution.
The technical solution adopted in the present invention is: a kind of combination type cofferdam, including the first weir plate, the second weir plate, riser, the end
Plate, manual jackscrew, nut, frid screw, angle steel weir notch, the first weir plate is that two end faces of common weir plate and weir plate are provided with
The circular tenon of multiple projections, the second weir plate two ends are provided with weir plate groove, cofferdam be shaped as rectangle, left and right two faces, cofferdam
Being made up of the first weir plate, former and later two faces are made up of the second weir plate, two ends of the first weir plate and the weir plate groove of the second weir plate
In all scribble one layer of waterproof material, the tenon of the first weir plate end insert in the weir plate groove of the second weir plate and by angle steel weir notch and
Frid screw is fixed, and embeds and be arranged parallel to the in the gap of the inner surface of the first weir plate and the joint portion of the second weir plate inner surface
The riser of one weir plate is also connected by screw and weir plate are fixing, and base plate is arranged on the bottom in rectangle cofferdam and passes through screw and weir plate
Fixing connection, the lower end of weir plate scribbles one layer of waterproof material, is equipped with angle steel weir notch, angle steel weir at four drift angles in rectangle cofferdam
One end face of groove is fixedly installed on the second weir plate outer surface by frid screw, and another end face by nut and manually pushes up
Silk is fixedly installed on the outer surface of the first weir plate.
Preferably, described base plate and riser are all made up of the rubber slab that 5mm is thick.
Preferably, screw is fixedly installed on an end face of angle steel weir notch, and manual jackscrew and nut are fixedly installed on angle steel
On another end face of weir notch.
Preferably, weir plate is made of stainless steel and weir plate surface configuration has waterproof layer.
Preferably, weir plate groove is the diameter diameter less than weir plate groove of circular weir board slot and tenon.
Compared with prior art, the invention has the beneficial effects as follows: by using 4 block length square weir plate composition cofferdam, wherein
Have 2 pieces of weir plates is respectively arranged at two ends with weir plate groove and manual jackscrew, and two end faces of other two pieces of weir plates are provided with multiple convex
The circular tenon risen, be inserted into respectively in circular weir board slot and and manually jackscrew and nut with the use of by 4 pieces of weir plate groups
Synthesizing rectangle cofferdam, circular tenon and circular weir board slot all scribble one layer of waterproof material, and base plate and riser are all by rubber slab system
Become so that the water resistance of whole combination type cofferdam structure is more preferable, uses this combination type cofferdam can clear up regional area in pond,
And water and the mud in cofferdam does not goes out to process pond, save substantial amounts of human and material resources and time, nor secondary can be caused dirty
Dye.
