Problems solved by technology

[0003] 1. When the water level of the river is lower than the elevation of the top of the pit, the upstream and downstream water flow will be cut off by the pit, or even cut off, blocking the migration of fish and affecting the aquatic ecological environment
[0004] 2. When a flood occurs, the water pit is completely impermeable, causing serious backwaters and affecting the flood discharge of the river
[0005] 3. After the water flow crosses the top of the pit, the flow rate increases greatly, causing serious erosion and emptying of the downstream river channel, affecting the stability of the downstream bank slope and the growth of aquatic organisms
[0006] 4. The body of the pit is made of masonry or concrete, which consumes a lot of cement lime and other materials, which is not conducive to environmental protection

Embodiment 1

[0042] Such as figure 1 , figure 2 As shown, a preferred landscape water pit in this embodiment includes: mortar masonry 1, dry masonry 2, planting green concrete retaining wall 3, tooth wall 4, ecological groove 5, groove wall 6, concrete base 7, Ecological frame 8, large stone 9, upstream gabion pad 10, downstream gabion cage gabion 11, cofferdam 12, anti-seepage geomembrane 13, sand bag 14, 15, water intake well, 16, water pump, 17, irrigation pipeline , 18, control circuit, 19, solar photovoltaic array, 20, controller, 21, moisture sensor.

[0043] In this embodiment, fill the upstream and downstream cofferdams 12 of the water pit, clear the foundation pit, and build the masonry foundation 1 with masonry. Large stones 8 are stacked on the foundation 1 to form a water pit. On the connecting section between the two banks of the water pit, the convex bank adopts a stepped ecological frame retaining wall 8, and the concave bank adopts a green planting ecological retaining ...

Embodiment 2

[0045] Such as figure 1 , figure 2 Shown, in the present embodiment, the long 0.5-0.8m of boulder 9 monoblocks of stacking, cross-sectional area 0.1-0.2m 2, the weight of a single block is 200-500kg, the long side is along the direction of water flow, the upper and lower layers are stacked alternately, the width of the top of the pit is 0.5m, the height of the pit is 0.5-1.0m, the ratio of upstream and downstream slopes is 1:1, and the width of the bottom of the pit is 1.5-3.0m.

[0046] Further, gabion mat apron 10 is installed in the upstream of Shuipi, with a thickness of 0.25m, a length of 1.0m, and a mesh diameter of 0.1m. The stones in the river dredging material are installed inside, and the diameter of the stones is 0.1-0.2m. Install gabion net box gabion 11 in the downstream of Shuipi, with a thickness of 0.5m, a length of 2.0m, and a mesh diameter of 0.1m. The stones in the river dredging material are installed inside, and the diameter of the stones is 0.15-0.4m. ...

Abstract

The invention discloses a landscape low dam. The landscape low dam comprises a masonry foundation, a rockfill dam body, an upstream gabion pad, a downstream gabion cage pannier, a convex bank step ecological frame retaining wall, a concave bank green planting concrete retaining wall, a solar energy water pump, a water intake well, an irrigation pipeline and a moisture sensor. Upstream and downstream cofferdams of a low dam are filled, a foundation pit is cleaned, the masonry foundation is constructed, the upstream gabion pad and the cage pannier are correspondingly installed at the upstream and the downstream of the low dam, and large stones are stacked on the masonry foundation to form the low dam. On a connecting section of both banks of the low dam, the step ecological frame retaining wall is used for a convex bank, the green planting concrete retaining wall is used for the concave bank, a dry masonry is used for the protection of a retaining wall foot, and the water intake well, the solar energy water pump, the irrigation pipeline and the moisture sensor are arranged to realize automatic irrigation according to the soil moisture content. The invention further discloses a construction method of the landscape low dam. An upstream water level can be raised to provide a water channel for fish to swim back, river dredging materials are fully used, the structure is novel, and implementation is convenient.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a landscape water pit by stacking boulders and a construction method thereof. Background technique [0002] Shuipi is a low-head rolling dam built to block rivers, and it is widely used in southern provinces such as Guangdong and Fujian. Water pits are often constructed of concrete or masonry, and meet the requirements of seepage stability and structural stability. But there are disadvantages as follows: [0003] 1. When the water level of the river is lower than the elevation of the top of the pit, the upstream and downstream water flow will be cut off by the pit, or even cut off, blocking the migration of fish and affecting the aquatic ecological environment. [0004] 2. When a flood occurs, the water pit is completely impermeable, causing serious water backlogging and affecting the flood discharge of the river. [0005] 3. After the water flow crosses ...
