DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example

[0024] In this embodiment, the water conservancy project slope protection support structure includes: a plurality of support units and a plurality of cables 6.

[0025] Each supporting unit comprises: a lower layer of protective bricks 1 a , an upper layer of protective bricks 1 b , four lower fixing members 4 , four large fixing members 5 and eight plungers 8 .

[0026] The lower layer of protective bricks 1a and the upper layer of protective bricks 1b have the same shape. In this embodiment, the lower layer of protective bricks 1a and the upper layer of protective bricks 1b are regular hexagons; of course, they can also be squares or regular octagons; relatively speaking, the regular hexagonal protective bricks are not only beautiful, but also can be squeezed and fixed with the surrounding 6 protective bricks, and are very firm.

[0027] like Figure 2As shown, the edges of two adjacent lower-layer protection bricks 1a between each supporting unit are aligned; of course, the edges of two adjacent upper-layer protection bricks 1b must also be aligned.

[0028] The upper surface of the lower protective brick 1a has three straight lower connecting grooves 2a, and the two ends of each lower connecting groove 2a are located at the center of the two opposite sides. In this embodiment, four lower fixing holes 3a are symmetrically arranged on both sides of each lower connecting groove 2a, that is, the lower protective brick 1a has 12 lower fixing holes 3a that penetrate from top to bottom.

[0029] The lower surface of the upper protective brick 1b has three straight upper connecting grooves 2b, and the two ends of each upper connecting groove 2b are located at the center of the two opposite sides; and the position is consistent with the lower connecting groove 2a. In this embodiment, four upper fixing holes 3b are symmetrically arranged on both sides of each upper connecting groove 2b, that is, the upper protective brick 1b also has 12 upper fixing holes 3b that penetrate from top to bottom. The positions and sizes of the lower fixing holes 3a and the upper fixing holes 3b are consistent, and correspond one to one.

[0030] The cross sections of the lower layer communication groove 2 a and the upper layer communication groove 2 b are semicircular with the same size, and match the size of the cable 6 .

[0031] The lower layer of protective bricks 1a is laid on the base layer, and the cables 6 are embedded in the lower layer connecting grooves 2a-1, passing through a number of lower layer protective bricks 1a. Of course, each lower layer protective brick 1a crosses through two cables 6, leaving an idle lower layer connecting groove 2a. This can reduce the use of cables 6, and setting up three staggered connecting grooves is convenient for construction workers to place the protective bricks, and there will be no placement errors. If there are only two lower layer connecting grooves 2a, it is easy to place the wrong ones during placement, which makes it difficult to connect and fix the cables 6 to form a protective network;

[0032] In this embodiment, the lower fixing member 4 includes a curved tube 41, two nail caps 42, two fixing blocks 43 and two nails 44. The two ends of the curved tube 41 are symmetrically fixedly connected to the two fixing blocks 43, and the fixing blocks 43 are provided with upper and lower through holes; the size of the through holes is smaller than the size of the nail caps 42 and larger than the size of the nails 44; the nail caps 42 are correspondingly fixed to the upper ends of the nails 44; and the nails 44 pass through the through holes.

[0033] Two nails 44 of a lower fixing member 4 respectively pass through the lower fixing holes 3a on both sides of a lower layer connecting groove 2a and are fixed in the base layer. The bent pipe 41 is pressed on the cable 6. Two lower fixing members 4 are arranged in front and behind each lower layer connecting groove 2a for fixing. Thus, 8 lower fixing holes are used by the lower fixing members and become the used lower fixing holes 3a-1, and the other four become the idle lower fixing holes 3a-2.

[0034] In order to avoid the lower fixing piece 4 protruding from the lower protective brick 1a, the lower surface of the upper protective brick 1b also has a plurality of accommodating grooves 2b-1; each upper connecting groove 2b has two accommodating grooves 2b-1; the size and position of the accommodating grooves 2b-1 match the bent pipe 41, the nail cap 42 and the fixing block 43.

[0035] The upper protective brick 1b is arranged on the lower protective brick 1a, and of course the edges of the two are aligned, the lower connecting groove 2a is aligned with the upper connecting groove 2b, and the lower fixing hole 3a is aligned with the upper fixing hole 3b. The elbow 41, the nail cap 42 and the fixing block 43 are partially embedded in the receiving groove 2b-1.

[0036] In this embodiment, the large fixing member 5 includes a nail rod 51, a rubber sleeve 52 and a top cover 54. The lower end of the nail rod 51 is a threaded nail head 53; the top of the nail rod 51 is connected to the top cover 54 by a threaded fixation; the top cover 54 is spherical in shape and can be a stone ball or a plastic ball. The rubber sleeve 52 is sleeved on the circumference of the nail rod 51. The threaded nail heads 53 of the four large fixing members 5 pass through the four upper fixing holes 3b and the idle lower fixing holes 3a-2, and extend into the soil of the slope base, so that the protective bricks are firmly fixed on the slope. The connection between the rubber sleeve 52 and the upper surface of the upper protective brick 1b is coated with an adhesive for sealing, which can prevent water seepage from loosening the large fixing member 5. The large fixing member 5 fastens the upper protective brick 1b and the lower protective brick 1a together and fixes them on the slope protection. The top cover 54 is mainly used to protect the top of the large fixing member 5 so that the large fixing member 5 is not exposed to the outside, which can effectively prevent the nail rod 51 of the large fixing member 5 from stabbing the staff after falling during construction. At the same time, the smooth outer wall of the top cover 54 is conducive to the circulation of water flow, and the spherical setting can reduce the impact force of water flow on the surface of the top cover 54.

[0037] The plunger 8 is a rubber plug, which matches the size of the upper fixing hole 3b and is inserted into the remaining upper fixing hole 3b. During use, the use of the large fixing piece 5 and the lower fixing piece 4 can be reduced according to actual conditions, but the remaining sockets must be plugged with the plunger 8 to protect the lower fixing piece 4 and the cable 6 inside, and prevent water seepage from carrying away soil and causing the large fixing piece 5 and the lower fixing piece 4 to loosen.

[0038] The support units are evenly arranged on the slope protection, and the cables 6 are connected to each support unit in a mesh shape. A retaining wall 7 is set at the top and bottom of the dam. The retaining wall 7 is formed by pouring concrete. The two free ends of the cables 6 are fixed in the retaining wall 7 and fixed by pouring concrete.

[0039] Preferably, a rubber pad is provided between the upper protective brick 1b and the lower protective brick 1a, and a through hole corresponding to the upper fixing hole 3b is provided on the rubber pad. The rubber pad can prevent the upper and lower protective bricks from being squeezed and broken, and when the large fixing piece 5 is used for fixing, there is no need to worry about the lower protective brick 1a being broken.
