Description
Technical Field
The invention relates to the technical field of hydraulic engineering, in particular to a hydraulic engineering flood prevention revetment.
Background
The flood prevention slope protection refers to a general term of various paving and planting on a slope surface for preventing the 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 gabion cages splendid attire stones independent each other and is formed, and the gabion cage carries out spacingly to the stone, and the stone is difficult for shifting or droing when making rivers wash away to enable the stone and pile up to higher height, have bigger dead weight to compress tightly the river bank, play the effect of flood prevention.
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 clearance between the stone and corrode the earth of gravel layer below river bank, and because the gravel layer shelters from the sunshine of below earth, make the vegetation can't grow at the earth of gravel 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 gravel layer below loose, soak soil erosion and water loss under for a long time easily, make the gravel 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 hydraulic engineering flood prevention revetment which has the advantages that the survival capability of vegetation on the revetment is improved, and the water and soil loss resistance capability of the revetment is further improved.
The above object of the present invention is achieved by the following technical solutions:
a hydraulic engineering flood prevention slope protection comprises a plurality of gabion cages which are laid side by side and are filled with stones, and further comprises a plurality of cylindrical planting pipes which are spliced with a slope surface, wherein the planting pipes are arranged in a hollow mode, two ends of each planting pipe are communicated, each planting pipe comprises at least two groups of arc plates which are identical in shape and independent of each other, the arc plates are mutually abutted, and the top ends of the arc plates are jointly sleeved with positioning covers for limiting the arc plates; the bottom end of the planting pipe penetrates through the bottom surface of the gabion cage, and the top end of the planting pipe extends out of the top surface of the gabion cage.
Through adopting above-mentioned technical scheme, the gabion cage carries out spacing messenger stone to the stone and gathers together to utilize the dead weight of stone with domatic compaction, and the stone can resist the direct erosion and corrosion of rivers, provide the protection to the bank protection.
