Abstract
The invention provides a side slope net hanging spray-seeding quick greening construction method, which is characterized in that a soft rock side slope is trimmed to a certain slope rate, a plurality of ribbed steel bars are driven into the side slope along the top of the slope, a steel wire net is hung on the slope surface through the ribbed steel bars, a plurality of layers of bamboo poles and a plurality of bundles of rice straws or wheat straws are horizontally bound on the steel wire net, and slurry containing grass seeds is uniformly sprayed on the slope surface through a slurry spraying device. The invention can actively protect the rocky side slope, not only realize the greening of the side slope, but also prevent the weathering of the rock of the side slope.
Description
Technical Field
The invention relates to the technical field of slope greening of civil engineering, in particular to a rapid greening construction method for slope hanging net spray-seeding planting.
Background
When roads and railways are constructed in mountainous areas, the soil and stone side slopes on two sides are generally constructed into a sheet stone concrete frame type structure in consideration of the stability of the side slopes, and grass seeds are scattered in the frame for greening. For rock slopes, the greening is difficult, and the rock slopes are stable in structure, so that the rock slopes are generally not protected actively. However, as time goes on, the exposed side slope rocks are gradually weathered, the stability is reduced, and hidden dangers are caused to safe operation of roads.
Disclosure of Invention
The invention aims to provide a construction method for slope hanging net spray-seeding planting greening, aiming at the problem that the slope greening is difficult due to stable rock quality and smooth slope surface, which can actively protect the slope through greening and avoid slope rock weathering.
The technical scheme of the invention is as follows:
a side slope net hanging spray-seeding quick greening construction method is characterized in that:
(1) slope repairing: trimming the slope rate of the soft rock side slope to 1:1.0-1: 1.5;
(2) installing an embedded part: inserting a ribbed steel bar at the top of the slope at certain intervals to ensure that the insertion depth is not less than 50cm and the distance from the slope surface is not less than 30 cm;
(3) hanging a steel wire mesh: laying a galvanized steel wire mesh on the slope, hanging the upper edge of the steel wire mesh with ribbed steel bars inserted and beaten at the top of the slope, and driving a certain number of ground anchors into the slope to fix the steel wire mesh on the anchor bolts so as to prevent the steel wire mesh from sliding downwards;
(4) binding bamboo poles: horizontally binding a plurality of layers of bamboo poles on the steel wire net, wherein the distance between adjacent bamboo poles in each layer is 1m, the distance between adjacent layers is 1m, and the adjacent layers are arranged in a vertically staggered manner;
(5) binding straw or wheat straw: binding a plurality of bundles of straws or wheat straws between two layers of bamboo poles on each layer of the steel wire mesh;
(6) spray seeding and planting grass seeds: uniformly spraying the mud containing the grass seeds on the slope surface by a spraying device, wherein the thickness of the mud is 20 cm.
The method is characterized in that the slope is hung with the net, grass seeds are mixed in the slurry, the mixture is stirred according to a certain proportion, and finally the mixture is sprayed on the slope through the spraying machine, so that greening is realized on the slope, and side slope rock weathering is prevented.
Detailed Description
The following describes the implementation of the present invention by a specific embodiment.
Firstly, material preparation:
(1) embedding parts: the embedded part adopts ribbed steel bars with a certain diameter and is embedded on the slope top for hanging a net.
(2) Steel wire mesh: the steel wire mesh adopts a machine-woven galvanized steel wire mesh as a structural framework.
(3) Bamboo poles or wooden sticks: the diameter is 3cm, and the length is 1m, and the device is used for preventing mud from flowing on the slope.
(4) Anchoring: ribbed steel bars with a diameter of 10mm were used. And anchoring the steel wire mesh on the side slope on the slope surface.
(5) Straw or wheat straw: processing the straws or wheat straws into segments of 50cm, and binding the straws or wheat straws into a plurality of small bundles by using binding wires.
(6) Slurry: the fertilizer is prepared by stirring and mixing plowing soil, organic fertilizer, peat soil, wood fiber and grass seeds according to a certain proportion.
Secondly, the construction process of hanging net, spraying, sowing, planting and greening comprises the following steps:
(1) slope repairing: firstly, according to a design drawing, the slope surface slope rate of the soft rock slope is trimmed to be 1:1.0-1: 1.5.
(2) Installing an embedded part: and inserting the ribbed steel bars processed before into the top of the slope, and ensuring that the insertion depth is not less than 50cm and the distance from the slope surface is not less than 30 cm.
(3) Hanging a steel wire mesh: the machine-woven galvanized steel wire mesh is laid on the slope surface from top to bottom and from left to right, the anchor nails are punched into the slope surface, and the steel wire mesh is fixed on the anchor nails to prevent the steel wire mesh from sliding downwards.
(4) Binding bamboo poles: and horizontally binding each section of bamboo pole or wooden stick on the steel wire mesh by adopting binding wires to form a plurality of layers of bamboo poles on the steel wire mesh. The distance between adjacent bamboo poles in each layer is 1m, the distance between adjacent bamboo poles is 1m, and the adjacent bamboo poles are staggered up and down to prevent the following slurry sprayed during spray seeding from flowing under the action of self weight, so that the grass seeds are not uniformly sowed.
(5) Binding straw or wheat straw: binding prepared small bundles of straws or wheat straws between every two layers of bamboo poles or wood sticks on the steel wire net according to a certain distance, wherein the straw or wheat straws are used as habitats of grass seeds in the slurry, and provide nutrients for forage when the straws or wheat straws are rotted.
(6) Spray seeding and planting grass seeds: uniformly spraying the prepared slurry on a slope surface by special slurry spraying equipment, wherein the thickness of the slurry is 20 cm.
