Description
Technical Field
The utility model relates to a steel sheet pile cofferdam specifically is a movable drainage water conservancy diversion steel sheet pile cofferdam.
Background
Under the deep water condition, the project needs to fill cofferdams to create dry construction conditions, wherein the steel sheet pile cofferdam is a cofferdam structure which is widely applied. When closure of the closure opening of the steel sheet pile cofferdam is carried out, the closure is affected by water (tide) flow conditions, and the direct closure is difficult.
In plain river network areas, to cope with floods, short-term plugging of flood control gaps at water flow intersections is required. Due to the fact that flood peak height, duration are short, damage is large, temporary plugging by the aid of the earth-rock cofferdam is difficult, and the recycling rate is low.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a movable drainage diversion steel sheet pile cofferdam which can conduct diversion under the deep water condition so as to be beneficial to closure of a closure gap; and the flood control gap at the river network water flow intersection of the plain can be plugged for a short time.
The utility model adopts the technical proposal that: a movable drainage diversion steel sheet pile cofferdam is composed of a plurality of structural units; each structural unit comprises two customized steel sheet piles, two flap valves, two sections of steel culvert pipes and an inserting plate door; the flap valve is fixedly connected to the outer sides of the customized steel sheet piles through fasteners respectively, steel culvert pipes are fixedly connected among the customized steel sheet piles, and the inserting plate door is fixedly connected among the steel culvert pipes.
The flap valve is provided with a detachable valve plate.
And the adjacent structural units are fixedly connected through fasteners such as bolts, nuts and the like.
And water stopping pieces such as rubber water stopping rings are arranged between the adjacent structural units for stopping water.
Thus, a plurality of structural units are assembled to form the drainage and flow guide channel.
The utility model can firstly make the steel sheet pile, and other components are installed on the construction site; and the whole construction can be carried out on site after all the components are installed.
The utility model has the advantages that:
(1) the utility model can directly guide the flow, and reduce the closure difficulty during the construction of the common steel sheet pile cofferdam;
(2) for rivers with small flow, the utility model can be used to realize full-section plugging and reduce the adverse effect caused by the construction of sectional diversion;
(3) the utility model can be opened and closed temporarily according to the requirement, and has good adaptability;
(4) the utility model discloses can recycle, practice thrift the engineering investment.
