Embodiment 1

[0034] Embodiment 1: as figure 1 As shown in -8, the fence interlocking block, the outline of the fence interlocking block is a rectangular block, the left and right two symmetrical sides are planes, the front and rear two symmetrical sides are interlocking planes, the bottom surface is a plane, and the top surface is a plane; the fence interlocking block The block is provided with permeable fence water-permeable strip holes 7 from the top surface to the bottom surface; the interlocking surface includes a middle section and two end sections, the middle section is the upper part 3 convex and the lower part 4 concave / the upper part 3 concave and the lower part 4 convex, and the two end sections are the upper part 1 , 5 concave lower part 2, 6 convex / upper part 1, 5 convex lower part 2, 6 concave, the length of each section of the two end sections is 1 / 2 of the length of the middle section, and the corresponding middle section and two end sections on the same level The concav...

Embodiment 2

[0037] Embodiment 2, as Figure 9 As shown in -16, the difference from Example 1 is that the top surface of the fence interlocking block is a plane with roughening 8, and the roughening 8 is a protrusion arranged on the front side or rear side of the top of the fence interlocking block near the edge platform. Figure 11 In 11 places, protrusions and grooves appear alternately in the width and thickness directions, with the same shape, which are used for spatial interconnection, increasing stability and flood resistance.

[0038]The production process of the above-mentioned fence interlocking blocks includes molds that match the shape of the above-mentioned fence interlocking blocks. The production steps are: (1) selection and proportioning of concrete raw materials, viber consistency of 15-30s, and water-cement ratio of 0.40-0.45 , the sand rate is 35-40%; the cement is PO42.5 ordinary Portland cement, the coarse aggregate is crushed stone with a particle size between 5-10mm,...

Abstract

The invention discloses a fence linkage block. The outline of the fence linkage block is a rectangular block, the left and right symmetrical lateral surfaces are planes, the front and rear symmetrical lateral surfaces are linkage surfaces, the bottom is a plane, and the top is a plane or a rough plane; the fence linkage block is provided with a communicated fence water pervious strip hole from the top to the bottom; and the linkage surface comprises a middle section and two end sections, the middle section is up convex and down concave or up concave and down convex, the two end sections are up concave and down convex or up convex and down concave, the formation length of each of the two end sections is 1/2 of the formation length of the middle section, and the heights of the concave part and the convex part of the corresponding middle section and two end sections on the same horizontal height are equal. A production process of the fence linkage block comprises the following steps of: selecting and proportioning concrete raw materials, and preparing concrete; pouring the concrete into a set die; curing; and detaching the external die. By organically combining three aspects of roughening wave dissipation, fence board wave dissipation and building block space linkage to improve the stability of a protected slope, the slope wave dissipating efficiency of a dam is improved, the thickness of the protected slope is optimized, deformation of the dam slope can be well adapted, and the construction is facilitated.

Description

technical field [0001] The invention relates to a dam fence interlocking block and a production process thereof. Background technique [0002] At present, the slope protection types commonly used for dams at home and abroad include concrete panels, riprap, dry stone, mortared stone, concrete slabs, and asphalt concrete slabs. It has been verified by wind and wave experiments that they can all play different degrees of wave dissipation. However, most of them have poor wave dissipation effect, or are huge in size, complicated in manufacturing and installation process, and require large investment. Upstream slope protection is an important part of the dam structure and an important measure to protect the safety and stability of the dam. Frost heave damage, slope protection deformed to fall off, resulting in dam body collapse and landslide, directly threatening the safety of the entire reservoir. Therefore, the selection of the upstream slope protection of the dam is very imp...
