Embodiment Construction

[0010] The core of the present invention is an ecological dam. In order to enable those skilled in the art to understand the technical solution more clearly, the following will be further described in detail in conjunction with the accompanying drawings and specific embodiments:

[0011] Such as figure 1 Shown: bagged clay 1, bagged gravel 2, vertically reinforced pine piles 3, horizontally reinforced pine piles 4, bamboo rafts on both sides of the top of the dam body 5, and bamboo rafts on the bottom of the dam body 6. The bagged clay 1 is the inner layer structure of the earth-rock dam body, and the overlapping width is not less than 30cm. The bagged crushed stone 2 is the outer layer structure of the earth-rock dam body, which is graded from 1 to 10 cm. The bagged crushed stones at the top and bottom of the dam body The thickness of the stone is 30-50cm, which plays a role of structural safety, and the thickness of other bagged gravel is 20-30cm. The bagged crushed stones ...

Abstract

The invention discloses an ecological water retaining dam. The whole dam body comprises three parts, i.e. an earth-rock dam body, a timber pile reinforcing structure and an isolating bamboo raft, wherein the earth-rock dam body is in a dual-layer structure; the inner layer is filled with bagged clay; the outer layer is filled with bagged gravel; the timber pile reinforcing structure is used for ensuring the safety and the stability of the dam body; and the isolating bamboo raft is used for reinforcing and isolating turbulence. Due to the adoption of natural material, the ecological water retaining dam disclosed by the invention has the advantages of stable structure, convenience in dismantlement and construction, and having the function of intercepting a water body, water conservation function for controlling the water level, and certain functions of purifying the water quality and repairing ecology as well as a landscape effect; and the ecological water retaining dam is suitable for construction of temporary water dams, short-term use of water dams or water retaining dams for middle and small creeks in river network regions and belongs to the fields of river pollution treatment and environment protection.

Description

(1) Technical field: [0001] The invention relates to a technology for river environment treatment, more specifically an ecological dam. (two) background technology: [0002] In the environmental management of rivers, temporary interception or blockage measures are often used for environmental protection dredging or river embankment construction. The interception method used is mainly to build temporary dams, which is also a method often used in construction. However, temporary dams are mostly piled with bagged soil or clay or construction waste materials. Their structural safety has not attracted everyone's attention, and their appearance is very unsightly. It not only affects the surrounding environment of the construction area, but also has no purification ability for water bodies. Not to mention the restoration of ecological functions. Especially in the river network area, there will be such a situation where temporary dams also take into account pedestrian passages. Som...
