Description
Technical field
Construction of hydro project cofferdam is the utility model is related to, more particularly in river course or river bank hydraulic structure was constructed
A kind of arc double-row steel pipe pile cofferdam in journey.
Background technology
Water conservancy structure all be unable to do without water, and a lot of hydraulic structures are all built in water or river bank, dry in order to create
It is necessary to build construction cofferdam, conventional construction cofferdam has the condition of ground construction：Earth rock cofferdam, steel sheet-pile cofferdam, steel pipe pile cofferdam
Deng.But some engineerings are influenceed by place, source of fetching earth, geology, soil permeability coefficient, SEA LEVEL VARIATION etc., and the cofferdam of the above can not
Meet special construction requirement, several cofferdam will be carried out integrated application by this, meet Specific construction requirement.
Utility model content
In order to solve the above problems, the utility model provides a kind of arc double-row steel pipe pile cofferdam, and the utility model uses
Double-row steel pipe stake is spaced apart to be squeezed into soil, horizontally disposed camber, and mud is put among two row's steel-pipe piles, in order to anti-
Only mud is lost in, and waterproof canvas is put between mud and steel-pipe pile；In order that double-row steel pipe pile cofferdam is stable, in double steel
Pile tube top outer adds two horizontal curved steel tubes, is integrally fixed with steel wire rope, can meet a variety of construction requirements.
To achieve the above object, the utility model provides following technical scheme：
A kind of arc double-row steel pipe pile cofferdam, including steel-pipe pile and canvas, the steel-pipe pile is two rows, and river is inserted in lower end
Bottom, and be distributed to outer arcuate, the horizontal steel tube of lateral connection is respectively equipped with the both sides of two row's arc-shaped steel pile tubes, in two row's arcs
Canvas is respectively equipped with the inside of steel-pipe pile, soil is provided between described canvas and forms cofferdam.
Further, described horizontal steel tube is located at the both sides of two row's steel-pipe piles, horizontal and suitable apart from top 20-50cm
The arc for steel-pipe pile is set, a diameter of 5-10cm of horizontal steel tube.
Further, described canvas top is arranged on horizontal steel tube, and following pendant has fragment of brick and is placed in bed mud.
Further, two described row's arc-shaped steel pile tube upper ends are interconnected and fixed integrally provided with steel wire rope.
If being constructed in korneforos, then the upstream and downstream in construction area respectively sets described curved steel tube pile cofferdam, if in
River bank is constructed, and can set curved steel tube pile cofferdam along semi-surrounding is applied at area, if in lake, korneforos construct, can be along applying
Work zoned circular, which surrounds, sets round steel pipe pile cofferdam.
The beneficial effects of the utility model
1. steel pipe pile cofferdam can save space, the earthwork is saved, double-row steel pipe stake can increase the stability in cofferdam itself.
2. the cambered design in cofferdam adds the resistance to water；
3. gathering materials on the spot, fetch earth, restored to the original state after use nearby；
4. canvas reduces the seepage in cofferdam.
