Description

Technical Field

[0001] This application relates to the field of waterproofing and flood control, and particularly to a slope protection for preventing seepage in water conservancy flood control. Background Art

[0002] In water conservancy projects, anti-seepage measures are of extremely important significance for flood control. Effective anti-seepage can avoid abnormal seepage and leakage of water flow, enhance the stability and reliability of water conservancy facilities, and thus ensure the safety of surrounding areas during floods. Flood control slope protection plays a key role in waterproofing and flood control.

[0003] The slope protection includes concrete slope protection, ecological slope protection and gabion slope protection. Among them, the concrete slope protection is firm and durable and can withstand a large water flow impact to provide good protection.

[0025] In water conservancy projects, anti-seepage measures are of extremely important significance for flood control. Effective anti-seepage can avoid abnormal seepage and leakage of water flow, enhance the stability and reliability of water conservancy facilities, and thus ensure the safety of the surrounding areas when floods come. The flood control slope protection plays a key role in flood prevention and control.

[0026] The slope protection includes concrete slope protection, ecological slope protection, and gabion slope protection. Among them, the concrete slope protection is firm and durable and can withstand large water flow impacts to provide good protection. In order to facilitate the production of the concrete slope protection and ensure the quality of the concrete, the slope protection can be formed by splicing precast concrete blocks. This type of slope protection is easy to manufacture and has a good protection effect. However, there will be gaps between the precast concrete blocks of this type of slope protection, and water will seep into the soil from the gaps of the slope protection when the water flows through.

[0027] To this end, please refer to Figure 1 , the present application provides a slope protection for anti-seepage water conservancy flood control, including a plurality of precast concrete blocks 1, connecting members, and a sealing layer 2.

[0028] Please refer to Figure 1 , a plurality of precast concrete blocks 1 are arranged in sequence along the width direction of the concrete blocks. A clamping protrusion 12 and a clamping recess 11 are provided between two adjacent precast concrete blocks 1, and the clamping protrusion 12 extends into the clamping recess 11. The precast concrete block 1 can be a concrete block, and its shape can be set according to needs. For example, it can be a square block, an arc block, or a special-shaped block.

The connecting member can be made of metal. The connecting member can connect two precast concrete blocks 1, or can connect three or other numbers. The connecting member can be bolts, metal brackets and embedded parts, or can be other structures. The structure for connecting the precast concrete blocks 1 belongs to a conventional structure and will not be elaborated here.

[0030] Please refer to Figure 1 , a sealing layer 2 is arranged between two adjacent precast concrete blocks 1. The sealing layer 2 is used to fill the gap between two adjacent precast concrete blocks 1, and the sealing layer 2 extends along the width direction perpendicular to the precast concrete block 1 and the thickness direction perpendicular to the precast concrete block 1.

[0031] Please refer to Figure 1 , the sealing layer 2 can be made of rubber, or can be made of foam or other materials; the extending direction of the sealing layer 2 can be the length direction of the joint surface of two precast concrete blocks 1. At this time, the sealing layer 2 as a whole can be straight, or can be curved or shaped, as long as it can play a role in preventing water seepage.

[0032] Please refer to Figure 1 , the precast concrete blocks 1 in the present application can be connected in sequence through the clamping protrusions 12 and the clamping depressions 11, and are reinforced by the connecting members, so that the overall slope protection has sufficient strength for use, and at the same time, each part of the concrete has good quality; the sealing layer 2 can be filled between two adjacent precast concrete blocks 1 and supplement the gaps between the adjacent precast concrete blocks 1, avoiding water leakage from the gaps of the slope protection, improving the quality of the slope protection, and at the same time, can enhance the water seepage prevention ability of the slope protection.

[0033] Please refer to Figure 2 , in some examples, the sealing layer 2 can be arranged outside the clamping protrusions 12 and the clamping depressions 11 so that the sealing layer 2 has a more stable sealing effect.

[0034] In some examples, in order to reduce the thickness of the sealing layer 2 and improve the overall strength of the slope protection, the thickness of the sealing layer 2 can be set between 2 mm and 20 mm, preferably 10 mm; the width of each layer of the sealing layer 2 can be 10% - 15% of the thickness of the precast concrete block 1, preferably 10%.

The multiple sealing layers 2 can further fill the gaps between the adjacent precast concrete blocks 1 and further improve the water seepage prevention ability of the slope protection.

[0036] Please refer to Figure 3 , in some examples, the number of the sealing layers 2 can be 2 to 5 layers, preferably 2 layers.

[0038] Please refer to Figure 3 , in some examples, the sealing layer 2 can be connected to any one of the precast concrete blocks 1 or can be connected to two precast concrete blocks 1 at the same time.

[0039] At this time, the sealing layers 2 can be adhered to both sides of each precast concrete block 1, and the two sealing layers 2 can be abutted when the precast concrete blocks 1 are spliced, so as to realize the sealing of the gap.

[0041] Please refer to Figure 3 , in some examples, the two side walls of the precast concrete block 1 here are the two side walls in the directions of the two precast concrete blocks 1 that are in contact with the precast concrete block 1; the simultaneous arrangement of the clamping protrusion 12 and the clamping recess 11 on one precast concrete block 1 can make all the precast concrete blocks 1 form a stacking structure similar to building blocks, which is convenient for the positioning and assembly of the precast concrete blocks 1.

[0042] Please return and refer to Figure 2 , in some examples, the clamping recess 11 extends along the extension direction of the sealing layer 2 and penetrates through two opposite side walls of the precast concrete block 1; the clamping protrusion 12 extends along the extension direction of the clamping recess 11, and the length of the clamping protrusion 12 is correspondingly set with the length of the clamping recess 11, and the clamping protrusion 12 extends into the clamping recess 11.

At this time, the axis of the snap projection 12 can be a straight line, a curve, or an alternating formation of a straight line and a curve.

[0046] Please refer to Figure 3 , in some examples, the number of the snap recesses 11 on each precast concrete block 1 can be 2 to 4, preferably two, and the number of the snap projections 12 can be the same as the number of the snap recesses 11.

[0047] Please refer to Figure 3 , in some examples, the snap projection 12 and the corresponding snap recess 11 are of equal size, so that the snap projection 12 can extend into the snap recess 11; the snap projection 12 and the snap recess 11 are at corresponding heights, so that the surface of the spliced precast concrete block 1 is flat.

[0048] Please refer to Figure 3 , in some examples, a snap projection 12 extends into the corresponding snap recess 11; the slope protection for flood control with anti-seepage water conservancy also includes a flexible layer 4, and the flexible layer 4 is arranged between the snap projection 12 and the snap recess 11. The flexible layer 4 can further fill the gap between adjacent precast concrete blocks 1, thereby further improving the waterproof ability of the slope protection.

[0049] In some examples, the flexible layer 4 can be a foam layer, a rubber layer or a plastic layer, as long as the flexible layer 4 can be filled between the snap projection 12 and the snap recess 11.

[0050] Exemplarily, the flexible layer 4 can be flexible, the flexible layer 4 can be fixedly connected to the inner wall of the snap recess 11 and abuts against the end face of the snap projection 12.

[0051] Please refer to Figure 2 , in some examples, the slope protection for anti-seepage water conservancy flood control further includes an anchor post 3.

[0052] Please refer to Figure 3 , in some examples, the anchor post 3 can be made of metal or non-metal. The anchor post 3 can be inserted into the precast concrete block 1, or can be connected by bonding or other means. The anchor post 3 can be arranged perpendicular to the back of the precast concrete block 1, or can be arranged obliquely.

[0053] Please refer to Figure 3 , in some examples, a plurality of anchor posts 3 are arranged, and the plurality of anchor posts 3 are distributed at intervals. The plurality of anchor posts 3 can further improve the connection strength between the precast concrete block 1 and the soil.
