A construction method based on the bow-and-arrow-shaped slope reinforcement structure as claimed in claim 9, characterized in that: the method comprises the following steps:

1) Prefabrication of annular waste tire strips (1): Select the tread width as the waste tires with a tread width of 20-30cm and a radius of 35-40cm, cut into two halves at 1/2, and then use 4-5cm The width of the strip is cut to form a 180° annular waste tire strip (1);

2) According to the size of the annular waste tire strip (1) prepared in step 1), a detachable embedding mold (5) is made:

Two detachable sleeves (51) in the shape of an 80° annular pipe wall are made, the inner wall radius of the detachable sleeve (51) is 25-56 cm, the pipe wall thickness is 0.1-0.2 cm, and the pipe diameter is 4.5- 5.5cm;

A detachable connecting pipe (52) having a shape of a 30° annular pipe wall is manufactured, the diameter of the detachable connecting pipe (52) and the detachable connecting pipe (52) are 4.8-5.8 cm, and the radius of the inner wall is 26-57 cm , the tube wall thickness is 0.1-0.2cm; the double-lobed cone shoe (53) is set at the bottom of the detachable sleeve (51) through the hinge (531), and the double-lobed cone shoe (53) consists of two identical conical plates (532). ), which are respectively hinged on both sides of the bottom of the casing through hinges (531);

Two positioning tubes (62) with a shape of a 45° annular tube wall are made, the inner wall diameter of the positioning tubes (62) is 4.8-5.8 cm, the inner wall radius is 26-58 cm, and the tube wall thickness is 0.1-0.2 cm;

Making the positioning sleeve (6): making two triangular sleeve disks (611) and three legs (612), the two legs (612) are at 120° to form two positioning brackets (61);

3) Embedding of the detachable embedding mold (5): According to the arrangement position of the annular waste tire strip (1) determined in step 1), use the prepared positioning sleeve (6) to position the slope on both sides, and use low-strength The tape closes the double-lobed cone shoe (53) at the bottom of the sleeve (51), and along the annular path of the positioning tubes (62) on both sides, the detachable embedding mold (5) with the double-lobed cone shoe (53) is placed. ) pressed into the slope to be reinforced (3);

4) Placement of the annular waste tire strip (1): first remove the detachable connecting pipe (52), insert the annular waste tire strip (1) into the strip hole of the detachable embedding die (5), and pull out the detachable sleeve (51), and then fill the foreign soil (4) with grass seeds on both sides of the annular waste tire strip (1) and compact;

5) Driving and anchoring of soil nails (2): Directly drive soil nails (2) with bolts into the side to be reinforced on the surface of the annular waste tire strip (1) tangent to the side slope (3) to be reinforced. in the slope (3), and fixed on the surface layer of the annular waste tire strip (1);

6) Repeat steps 3) to 5) until the surface layer of the slope (3) to be reinforced is completely covered.
