Embodiment 1

[0027] Example 1 as Figure 1-8 As shown, the water intake facility for the shallow section of the bearing layer at the bottom of the river bed consists of a water intake head 1, a water diversion steel pipe 2, a steel box foundation 3, a seamless steel pipe 4, and an I-shaped steel support 5.

[0028] A water diversion steel pipe 2 is arranged on the water intake head 1 . The water intake head 1 is fixed on the top of the steel box foundation 3 through an I-shaped steel support 5 , and the I-shaped steel support 5 is fixed on the top of the steel box foundation 3 by bolts or welded on the top of the steel box foundation 3 .

[0029] The steel box foundation 3 is surrounded by two vertical side plates arranged perpendicular to the water flow direction and two semicircular side plates protruding outward along the water flow direction, that is to say, the connection line between the two vertical side plates and the water flow Direction is vertical. Each vertical side plate con...

Abstract

The invention discloses a water taking facility for a shallow section of a riverbed bottom bearing stratum and a construction method. The water taking facility comprises a water taking head part, a steel box foundation and a seamless steel pipe for connecting the steel box foundation and a rock layer at the lower part of the riverbed, wherein the steel box foundation is formed by enclosing two vertical side plates arranged in the direction perpendicular to the water flow direction and two arc-shaped side plates protruding outwards in the water flow direction, concrete is poured into the steel box foundation, the water taking head is installed at the top end of the steel box foundation, and a water diversion steel pipe is arranged on the water taking head. Steel plates on the outer side of the steel box foundation are used as construction formworks and pier foundations for permanent safe storage, and keel stand columns on the inner side of the steel box foundation are used as pier foundation permanent vertical stress parts. The steel box foundation is completed on a shore and only needs to be consigned by a large hoisting ship during hoisting, so that the construction cost is low, the time of occupying a river channel is short, and the environmental pollution is small.

Description

technical field [0001] The invention relates to a water intake facility and a construction method for a relatively shallow section of a bearing layer at the bottom of a river bed, and belongs to the field of water intake facilities for the construction of a waterworks or a pumping station. Background technique [0002] The river bed water intake facility of the waterworks or the water pump house refers to the water intake head, the water diversion pipe and the fixed underwater water intake pier. Its construction and installation has always been one of the most critical processes in the construction period of water plants. In general, in order to ensure the safety of water intake, the water intake head needs to extend into the river for a long distance and be set at a lower level of the river bed to prevent the river bed from silting up and affect the safety of water intake. In view of this, the general construction method adopts cofferdam construction, or uses piling boats ...
