Embodiment

[0041] combine figure 1 and image 3 , a water-retaining cofferdam structure, comprising a water-retaining cofferdam 1 arranged along the movement direction of a river. The water retaining cofferdam 1 includes a plurality of water retaining boards 2, and the water retaining cofferdam 1 formed by splicing the plurality of water retaining boards 2 is arc-shaped. The upper end of water retaining plate 2 is welded with two handles 14, is convenient to it is hoisted. The water retaining plate 2 is provided with slots 3 and welded blocks 4 on both sides of the water retaining plate 2 along the installation direction toward the river bed. catch. Each block 4 is coated with a water-stop strip 13 at its edge along its length direction. After the slot 3 is engaged with the block 4, the water-stop strip 13 expands when it encounters water, and the slot 3 and the block can be connected together. The installation gap of 4 is filled to reduce the inflow of river water from the gap betwe...

Abstract

The invention relates to a water-retaining cofferdam structure. The water-retaining cofferdam structure comprises a water-retaining cofferdam arranged in a river flowing direction; the water-retainingcofferdam includes a plurality of water baffles; the two sides of each water baffle are correspondingly provided with a clamping slot and a clamping block in the installation direction of the water baffle; and every two adjacent water baffles are clamped mutually through the corresponding clamping slot and clamping block. During construction of the water-retaining cofferdam, the water baffles areinstalled in the construction direction of the water-retaining cofferdam; the water baffles are driven into a riverbed and are fixed; then, the clamping blocks of latter water baffles are clamped into the clamping slots of corresponding former water baffles successively, and the water baffles are driven into the river bed and are fixed; and the operation is performed circularly in such a manner until the water-retaining cofferdam is formed. Compared with a way of filling woven bags with soil and directly piling up the woven bags filled with the soil, a way employed by a construction process for the water-retaining cofferdam structure is more convenient for construction of the water-retaining cofferdam, and the construction process has an effect of increasing construction efficiency.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a water retaining cofferdam structure and construction technology thereof. Background technique [0002] During the construction of the Linhe sewage treatment station, in order to ensure the safety of the later operation of the sewage treatment station, a retaining wall needs to be designed on the riverside side of the sewage treatment station to prevent water erosion. Since the retaining wall of the sewage treatment station is constructed next to the river, in order to ensure the safety of the construction work and the quality of the project, measures should be taken to prevent the river water from affecting the excavation of the foundation pit and the pouring of the retaining wall. [0003] In the existing technology, woven bags are usually used to irrigate soil along the direction of the river in the peripheral weir of the pouring position of the retainin...
