Box culvert structure and its construction method

Abstract

The invention discloses a box culvert type drainage port structure which comprises a drainage frame body and a filling and carrying frame body, wherein the drainage frame body comprises a bottom plate, side plates and a top plate; the filling and carrying frame body is arranged beside the side plates of the drainage frame body, so that a containing cavity capable of containing and carrying a filling material is formed; a cavity wall at the bottom of the containing cavity is formed in a manner that the bottom plate extends outwards from one end of each side plate; one side cavity wall of the containing cavity shares the side plates of the drainage frame body; the filling and carrying frame body comprises a side wall arranged opposite to the side plates and forming the other side cavity wall of the containing cavity, and a frame beam connected with the tops of the side plates and the side wall; and an opening is formed at the top of the containing cavity. A construction method of the box culvert type drainage port structure mainly comprises the steps that the box culvert type drainage port structure is arranged at a foundation bed, and the filling material is put into the filling and carrying frame body of the box culvert type drainage port structure. As the filling and carrying frame body is adopted, and the weight of the drainage port structure is increased by filling the filling material into the filling and carrying frame body, the box culvert type drainage port structure is good in wind wave resisting stability. In addition, the filling material is not required to be hoisted with the drainage port structure at the same time, so that the construction difficulty is reduced; the cost is low; and the construction is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of drainage of a water supply system, in particular to a box culvert type drainage outlet structure and a construction method thereof. Background technique [0002] For example, in thermal power projects, nuclear power projects or other industrial engineering systems, a large amount of water is often required, so a water supply system needs to be configured, that is, water is taken from the water area, and then discharged back to the water area after being used and recycled. The outfall is an important part of the water supply system. The box culvert structure is mostly used in industrial engineering systems to meet the possibility of construction, minimize the difficulty of construction, and reduce the cost of the project. [0003] The traditional box culvert type outfall mostly adopts an integral prefabricated reinforced concrete box culvert structure. The outfall box culvert is prefabricated on land or on...

Problems solved by technology

[0005] Based on this, it is necessary to provide a box culvert structure with good stability against wind and waves, low cost, and easy construction for the traditional box-culvert outfall structure with poor stability against wind and waves and unable to meet the installation requirements in stormy waters. At the same time provide the construction method of the outfall structure
