Description

Technical Field

[0001] The present invention relates to the technical field of slope protection, and specifically to a water conservancy precast block applicable to large-angle slopes and a slope protection construction method. Background Art

[0002] At present, there are two common slope protection structures in the fields of municipal administration and water conservancy:

[0003] One slope protection structure is to adopt concrete full slope protection or masonry slope protection. This kind of slope protection structure is relatively resistant to scouring and has a long effective slope protection time. However, the heat island effect is very obvious, and it is impossible to realize plant planting, and the ecological effect is very poor. Especially in the drawdown zone of large-angle slopes without vegetation coverage, this fully hardened slope protection hinders the exchange of river water and groundwater, and the land around the hardening project lacks moisture, resulting in land salinization, changing the ecological environment for plant growth, and causing the disappearance of plant populations;

[0004] The other is to use slope protection precast blocks for slope protection (such as hexagonal blocks, concrete grids, etc.). The effective slope protection time of this kind of slope protection form is too short, and it is easy for the precast blocks to loosen, slide and fall off between them, and the stability is insufficient. After using for a period of time, the slope body becomes loose, and there are certain potential safety hazards. Therefore, the present invention provides a water conservancy precast block applicable to large-angle slopes and a slope protection construction method. Summary of the Invention

[0005] The purpose of the present invention is to provide a water conservancy precast block applicable to large-angle slopes and a slope protection construction method to solve the problems raised in the above background art.

Four first locking parts and four second locking parts are arranged at the four peripheral edges of the precast block body. The four first locking parts are respectively arranged at the four corners of the precast block body, and a card slot is arranged between each first locking part and the second locking part. Planting through-holes and locking ports are opened on the surface of the precast block body, and a hook member is installed on the locking port. One end of the hook member is connected with a support anchor member, and the end of the support anchor member far from the hook member is fixedly installed on one side wall of the retaining wall.

[0007] As a preferred technical solution of the present invention, convex tips are provided at both ends of each first locking part, and a flat embedding end is provided at the end of the first locking part far from the precast block body.

[0008] As a preferred technical solution of the present invention, the cross-section of the second locking part is a triangular structure, and the cross-section of the card slot is a parallelogram structure.

[0009] As a preferred technical solution of the present invention, a rear convex seat is provided on one side of the precast block body close to the retaining wall, and the rear convex seat is sleeved outside the support anchor.

[0010] As a preferred technical solution of the present invention, the support anchor includes an inner rod, and one end of the inner rod is fixedly connected to the retaining wall.

[0011] As a preferred technical solution of the present invention, the support anchor further includes an outer rod fixedly sleeved outside the inner rod, and a pouring cavity is provided on the inner surface of the outer rod.

[0012] As a preferred technical solution of the present invention, a rod cavity is formed on the inner surface of the inner rod, and a steel cable is installed inside the rod cavity. An installation member is provided on one side of the hook member close to the support anchor, and one end of the steel cable is fixedly connected to the installation member.

[0013] As a preferred technical solution of the present invention, one end of the steel cable away from the installation member is fixedly connected to a slider, and the slider is slidably installed in the rod cavity.

The surface of the first pulley abuts against the outer surface of the inner rod. Second pulleys are provided on both sides of the steel cable, and the second pulleys are movably installed on the rod cavity.

[0015] As a preferred technical solution of the present invention, the support anchor and the retaining wall are fixedly connected through a fixing member.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The water conservancy precast block of the present invention applicable to large-angle slopes can enable good locking between adjacent precast block bodies during laying by providing a first locking portion, a second locking portion and a card slot on the precast block body, thereby greatly improving the stability of the slope protection surface formed by the precast blocks, avoiding the loosening and falling off between the precast blocks.

[0028] Please refer to Figures 1-5, in this embodiment, a precast hydraulic block applicable to a large-angle slope is provided, including a precast block body 1. Four first locking parts 2 and four second locking parts 3 are arranged on the four peripheral edges of the precast block body 1. The four first locking parts 2 are respectively arranged at the four corner positions of the precast block body 1, and a slot 4 is arranged between each first locking part 2 and the second locking part 3. A planting through-opening 5 and a locking opening 6 are formed on the surface of the precast block body 1, and a hook member 7 is installed on the locking opening 6. One end of the hook member 7 is connected with a supporting anchor member 8, and the end of the supporting anchor member 8 away from the hook member 7 is fixedly installed on one side wall of a retaining wall 9. Convex tips 21 are provided at both ends of each first locking part 2, and a flat embedding end 22 is provided at the end of the first locking part 2 away from the precast block body 1. The cross-section of the second locking part 3 is a triangular structure, and the cross-section of the slot 4 is a parallelogram structure. By arranging the first locking part 2, the second locking part 3 and the slot 4 on the precast block body 1, the adjacent precast block bodies 1 during laying can be well locked, thereby greatly improving the stability of the slope surface formed by the precast blocks, avoiding the loosening and falling off between the precast blocks. For a large-angle slope, it has a better slope protection effect, and realizes plant planting, improving the ecological environment and effect of this area. By using the cooperation of the locking opening 6, the hook member 7 and the supporting anchor member 8, the slope protection stability of the precast block body 1 on the slope 90 can be further improved, preventing the slope body from loosening and improving the safety performance during use.

[0029] In this embodiment, the support anchor 8 includes an inner rod 81. One end of the inner rod 81 is fixedly connected to the retaining wall 9. A rear convex seat 10 is provided on the side of the precast block body 1 close to the retaining wall 9, and the rear convex seat 10 is sleeved outside the support anchor 8. The support anchor 8 further includes an outer rod 83 fixedly sleeved outside the inner rod 81, and a pouring cavity 84 is provided on the inner surface of the outer rod 83. A rod cavity 82 is formed on the inner surface of the inner rod 81, and a steel cable 85 is installed inside the rod cavity 82. An installation member 71 is provided on the side of the hook member 7 close to the support anchor 8, and one end of the steel cable 85 is fixedly connected to the installation member 71. One end of the steel cable 85 away from the installation member 71 is fixedly connected to a slider 86, and the slider 86 is slidably installed in the rod cavity 82. One end of the slider 86 away from the steel cable 85 is connected to a spring 87, and one end of the spring 87 away from the slider 86 is connected to the inner side wall of the inner rod 81. A rod opening is formed at the position of the inner rod 81 on the rear convex seat 10, and a first pulley 88 is installed on the rod opening, and the surface of the first pulley 88 abuts against the outer surface of the inner rod 81. Second pulleys 89 are provided on both sides of the steel cable 85, and the second pulleys 89 are movably installed on the rod cavity 82. Among them, the rear convex seat 10 can not only be better embedded on the slope 90 to ensure better stability, but also can use the rear convex seat 10 to conduct better stable guidance for the inner rod 81. The support anchor 8 and the retaining wall 9 are fixedly connected through a fixing member 91. Among them, by using the pouring cavity 84, concrete can be poured on the outer rod 83 of the support anchor 8, so as to enhance the support strength of the support anchor 8. And by using the steel cable 85, the slider 86 and the spring 87, when the bottom of the precast block body 1 loosens due to soil erosion or other phenomena, the spring 87 can be used to tighten the steel cable 85, so that the hook member 7 automatically tightens the precast block body 1 in the direction of the slope 90, thereby effectively improving the slope protection effect of the slope surface and preventing the slope body from loosening.

[0030] The present invention also provides a slope protection construction method for a water conservancy precast block applicable to a large-angle slope, which specifically includes the following steps: First, drill holes in the retaining wall 9 and the slope 90, penetrate the support anchor 8 to the outside of the slope 90, and after fixing the support anchor 8 with the fixing member 91, pour concrete into the pouring cavity 84 of the outer rod 83. Then, lay the precast block body 1 on the slope, so that the precast block bodies 1 are locked with each other through the first locking portion 2, the second locking portion 3 and the card slot 4. At the same time, one end of the steel cable 85 is fixedly connected to the hook member 7 through the installation member 71, and the rear convex seat 10 sleeves the inner rod 81, and the hook member 7 is hooked on the side of the precast block body 1 away from the slope 90. At this time, the spring 87 is in a stretched state. When the hook member 7 is released, under the reset action of the spring 87, the hook member 7 can lock the precast block body 1 well. It should be noted that it is not necessary to install the support anchor 8 and the hook member 7 on each precast block body 1, and construction and installation can be carried out for targeted areas according to actual needs, or uniform arrangement at intervals can also be carried out.
