specific Embodiment approach

[0075] The structure of the clean water soft dam is as follows: Figure 2 ~ Figure 4 As shown, it includes four parts: the main dam body 26, the dam foundation 25, the grid 2 and the support frame 5, and is equipped with a synchronous backwash automatic control system.

[0076] The dam foundation 25 includes a subbase 6 and a side foundation 7. The subbase is arranged along the cross section of the river, and the side foundations are located at both ends of the subbase. 20%-30% of the total height, the base is a self-compacting fixed rubber base, such as steel beads; the side base is a water-filled rubber side base.

[0077] The main dam body 26 is divided into two or more mutually independent intervals along the cross section of the river by a partition plate 8 (rubber plate), each interval is a water purification unit 4, and the number of specific intervals is determined by the width of the river. The width of the section along the cross-section of the river is 1000mm-2000m...

Abstract

The invention discloses an assembled emergency water purification soft dam and a method for purifying a minitype river course by using a water purification soft dam. The water purification soft dam is composed of a dam foundation, a main dam body, a barrier and a supporting frame, wherein the main dam body is divided into two ore more than two independent water purification units by one or a plurality of partitions along the river cross section; and each region is composed of a downstream unit, a horizontal unit and an upstream unit along the water flow direction. The river water filtration and back flushing of the soft dam are carried out synchronously, and the back flushing wastewater is independently treated in a different position. The soft dam is easy to assemble and disassemble, has the characteristics of recyclable materials, small habitat fragmentation influence and the like, can purify polluted river water, and is suitable for the fields of river pollution treatment and ecological environment protection during minitype river course partial building works.

Description

technical field [0001] The invention relates to a pollution control technology for rivers, more specifically to a water purification soft dam used for emergency, convenient construction and disassembly during construction operations such as bridge repairs in small river courses. Background technique [0002] A filter dam is a structure or obstacle that is permeable, composed of earth, stone, concrete and other materials and filter materials, and has multiple functions such as water retention, water purification, and water level adjustment. Filter dams in a broad sense include: biological dams, sand filter dams, semi-permeable dams, seepage dams, etc. Filter dams have been widely used in ecological restoration of water bodies, flood control and water storage, and water level regulation. In recent years, due to the improvement of people's material living standards, in order to facilitate transportation, it is often necessary to build bridges, roads and other buildings on the ...
