Technical Field

The invention relates to the technical field of water conservancy revetments, in particular to a water conservancy revetments construction method.

Background

The water conservancy revetment refers to a general term for various paving and planting on a slope surface to prevent the side slope from being washed. The concave bank of the river bank is washed by water flow year by year or soaked by high water level in the flood season, so that the river bank is continuously collapsed. In order to protect the safety of bridges and embankments, protection must be built on the concave bank.

Among the current hydraulic engineering, in order to reduce domatic soil erosion and water loss, generally lay the metalling on domatic, current metalling is generally piled up through a plurality of check guest cage splendid attire stones that mutually independent each other and is formed, through advancing the stone dress into the flood prevention module that forms the rectangle in the check guest cage, check guest cage carries on spacingly to the stone, the stone is difficult for shifting or drops when making rivers wash away, and enable the stone and pile up to higher height, have bigger dead weight and compress tightly the river bank. The friction between the gabion cage and the stone and the river bank is large, the gabion cage is not easy to move due to water flow impact, the impact of the water flow can be resisted, the flow speed of the water flow is reduced, and the flood prevention effect is achieved.

The above prior art solutions have the following drawbacks: although the gabion cage that fills up the stone dead weight is great also can carry on spacingly to the stone, but rivers can see through the mesh of gabion cage and the earth of the clearance erosion rubble layer below river bank between the stone, and because the rubble layer shelters from the sunshine of below earth, the stone is also comparatively intensive in the gabion cage, make the vegetation can't take root growth at the earth of rubble layer below, and then because the root system that does not have the vegetation is to the soil fixation effect of earth, make the earth of rubble layer below loose, soak soil erosion and water loss under for a long time easily, make the rubble layer below appear collapsing after the cavity, consequently, there is the improvement space.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a water conservancy revetment construction method, which can improve the survival capability of vegetation on a revetment and further improve the water and soil loss resistance capability of the revetment.

The above object of the present invention is achieved by the following technical solutions:

a water conservancy slope protection construction method comprises the following steps:

the method comprises the following steps: prefabricating a gabion cage and a maintenance pipe assembly, wherein the upper end surface and the lower end surface of the gabion cage are both provided with plug-in holes larger than grids of the gabion cage;

step two: paving gabion cages on the river bank, and inserting and fixing the maintenance pipe assembly with the river bank through the inserting holes;

inserting vegetation in the maintenance pipe assembly, and inserting roots of the vegetation and a river bank for planting;

step four: stacking stones in the gabion cage until the gabion cage is full, and then sealing the gabion cage;

maintenance pipe subassembly cavity sets up and both ends link up, the maintenance pipe subassembly includes at least two sets of the same and independent arcs of shape each other, each arc butt each other, the arc top has cup jointed jointly and has carried out spacing location lid to each the arc, maintenance pipe subassembly periphery has cup jointed the position circle.
