Embodiment

[0044] The method of the present invention is used to carry out composite protection on a rocky slope, the rocky slope is 43 meters long, 10.5 meters high, and the slope ratio is 1:1.2.

[0045] Excavate the slope, brush the slope, clean the surface of the slope, set up drainage and intercommunication ditches for the slope, set out lines, locate the nailing points on the slope, and mark them.

[0046] Drive horizontal soil nails and vertical soil nails into the slope along the horizontal direction and vertical direction respectively. The depth of entry into the slope is not less than 200cm. 10-15cm above the horizontal line. The distance between adjacent horizontal soil nails in each soil nailing unit row is 140cm, the height difference between adjacent horizontal soil nails in each soil nailing unit row is 15cm, and the distance between adjacent soil nailing unit rows is 115cm.

[0047] The height of the prefabricated groove is equal to the height from the top of the vertica...

Abstract

The invention discloses a rock slope combined type protective structure and method. The protective structure comprises prefabricated grooves and multiple soil nailing unit rows. Each soil nailing unit row is composed of soil nailing units which are driven into a slope and arranged in a staggered mode high and low. Each soil nailing unit is composed of a horizontal soil nail and a vertical soil nail which are perpendicular to each other. One end of each horizontal soil nail is fixed to the corresponding vertical soil nail, each horizontal soil nail is driven into the slope in the horizontal direction, each vertical soil nail is driven into the slope in the vertical direction, and the top end of each vertical soil nail is higher than the horizontal line where the corresponding horizontal soil nail is located. The angle between a plane formed by the horizontal soil nails of the adjacent soil nailing units in each soil nailing unit row and the horizontal plane ranges from 4 degrees to 7 degrees and the prefabricated grooves are formed in the horizontal soil nails of the adjacent soil nailing units in the soil nailing unit rows. According to the structure and method, construction is convenient and rapid, the engineering manufacturing cost can be remarkably reduced, and the structure and method are suitable for protection of the rock slope generated in the manual digging process in traffic civil engineering.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a rock slope composite protection structure and method. Background technique [0002] The construction of a large number of domestic highways, railways and other infrastructure inevitably brings many exposed slopes. With the deepening of the concept of green environmental protection and sustainable development, higher requirements are put forward for the stability and aesthetics of exposed slopes. . At present, structural protection methods are often used for engineering slope protection. This type of method has the advantages of strong support capacity and high stability, but the cost of the project is high, and the degree of environmental protection and landscaping is low. [0003] At present, the commonly used rock slope protection methods include: (1) setting retaining structures, such as anti-slide piles or prestressed anchor cable anti-slide piles; (2)...
