Description

Structure that river course revetment and pump station installation combine

Technical Field

The utility model belongs to equipment and a device of general hydraulic engineering. In particular to a structure for mounting and combining a river revetment and a pump station.

Background

The comprehensive inland river regulation is an urgent need for enhancing the flood control and drainage capacity of cities, improving the city grade, improving the environment, beautifying the cities and benefiting residents. The first technical problems of comprehensive treatment are river channel clearing, node pump gate engineering and revetment renovation. The existing urban inland river revetment system is continuously built for decades, mostly dry-built, shallow in foundation and poor in wall integrity, completely does not meet the requirements of the existing relevant specifications, and theoretically should be dismantled and rebuilt. However, the urban inland river banks are usually densely constructed on the ground, densely arranged with underground pipelines and various trees on the banks, and these adverse factors impose strict requirements on the revetment reforming construction technology.

The revetment destruction modes can be broadly divided into three types: (1) the main manifestation of the damage of the revetment masonry is cracking of the revetment, bulging, hollowing out of the revetment and the like, which is one of the main damage modes. (2) Collapse of revetment belongs to the field of overturning damage. (3) And bank slope landslide. The revetment and the soil body at the rear part of the revetment generate integral shearing damage along a certain weak sliding surface (belt), the sliding surface is generally positioned in a sludge layer, and the sliding mass is usually in an arc-shaped nest shape, so that the damage force is large, and the danger and the hazard are the greatest.

The hydraulic engineering often needs to newly build a temporary cofferdam to close a construction site to form a dry land construction working face. After the cofferdam is built, the originally communicated water system is cut off, the water quality of the inland river is easy to deteriorate, and waterlogging is easy to form in the flood season. In response to this problem, it has been common to use a buried structureDrainage and water change are carried out by arranging a diversion pipe or erecting a temporary water pump on the bank. The drainage effect of the diversion pipe in plain areas is poor due to the limitation of sites and construction periods, and the temporary water pump usually adopts a submersible sewage pump or an axial flow pump with a small single pump flow (the single pump flow is usually 0.1 m)³And less than s), the number of the water pumps is large, and the management during emergency drainage is not facilitated.

SUMMERY OF THE UTILITY MODEL

For solving above problem, the utility model provides a structure that river course revetment and pump station installation combine combines river course revetment and pump station to arrange together.

In order to achieve the above purpose, the technical solution of the present invention is as follows: the utility model provides a structure that river course revetment and pump station installation combine, contains two rows of pile foundations of revetment barricade, and the pilot beam is pour at the pile bolck of two rows of pile foundations to its characterized in that, installs prefabricated assembly platform between two rows of pile foundation pilot beams, as the mounting platform of water pump.

Further, the two rows of pile foundations are close packed pile foundations and outside pile foundations arranged outside the close packed pile foundations, the hanging plate is arranged at the bottom of the outer side of the guide beam at the top of the close packed pile foundations, and an L-shaped reinforced concrete structure is arranged between the guide beam at the top of the close packed pile foundations and the revetment retaining wall.

Furthermore, an anchoring steel bar is arranged between the L-shaped reinforced concrete structure and the revetment retaining wall, so that the L-shaped reinforced concrete structure and the revetment retaining wall are connected into a whole and stressed uniformly.

Furthermore, the water pump adopts a submersible tubular pump, and a support on the pump shell of the water pump is welded with the mounting platform or is connected with the mounting platform by using bolts.

The device improves the rigidity of the foundation, and can meet the requirement that the maximum flow of a single pump is 1.5m³The scheme can effectively reduce the number of water pumps, improve the drainage and water exchange efficiency and ensure the water environment and water safety. The installation platform of water pump has all adopted prefabricated assembly platform, and the installation is fast with demolising, and all materials all recoverable recycling after demolising, have sustainability. The pile foundation combined with the arrangement device adopts a prefabricated square pile or a steel pipe pile, and the prefabricated square pile or the steel pipe pile is quickly driven into the river bottom by utilizing the sleeve, so that the pile foundation can be used for water construction without cofferdam cutoff. The construction efficiency is high, and is fast, takes up an area of for a short time, can be used to solve the flood control safety of flood season and inland river drainage waterlogging problem.
