Description

Technical Field

[0001] The utility model belongs to the field of civil engineering and water conservancy, in particular to a prefabricated concrete block component. Background Art

[0002] Concrete slope protection is a protective measure taken to prevent disasters such as collapse and subsidence of water engineering slopes. In addition to being affected by geographical properties such as topography, soil and gravel structure, natural slopes are also affected by weathering, water erosion, animal and human activities, and often face problems such as soil erosion and slope subsidence. In response to this situation, the slope needs to be hardened. The commonly used method is cement pouring, but on-site pouring is limited by the site, machinery and manual construction, so precast concrete blocks have become a new treatment method. Precast blocks can be mass-produced in different locations and then transported in batches, which is convenient, fast, low-cost and less restricted. However, the existing precast block components often lack connection structures, and the slope has poor integrity and low strength after construction. Utility Model Content

[0003] In view of the defects in the prior art, the utility model provides a prefabricated concrete block component, which is used to solve the problems in the prior art of lack of connection structure between prefabricated block components, poor integrity of the slope surface after construction, and low strength.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a prefabricated concrete block component, comprising: the component body is a right-angled isosceles triangle plate, two right-angled sides of the component body are respectively provided with protrusions and grooves, the protrusions and grooves on the different component bodies can be matched with mortise and tenon joints, a dovetail groove is opened on the hypotenuse of the component body, and the dovetail groove is located in the middle of the hypotenuse; the length of the hypotenuse is s, and s satisfies the following formula: s=a+b, wherein a represents the bottom width of the dovetail groove, and b represents the groove width of the dovetail groove; the angle α between the groove wall and the groove bottom of the dovetail groove is 45°.

[0005] Optionally, a plurality of through holes are provided on the component body.

[0006] Optionally, the through hole includes a first through hole and a second through hole, the first through hole and the two second through holes are arranged in a herringbone shape, and the two second through holes are arranged in mirror symmetry.

[0007] Optionally, the first through hole is an isosceles right-angled triangle hole, and the second through hole is a right-angled trapezoidal hole.

[0008] Optionally, a chamfered portion is provided at a top corner of the component body, and the chamfered portion is a straight line or an arc.

[0009] Optionally, the thickness of the component body is 150-250 mm.

[0010] Optionally, the length s of the hypotenuse is 600mm-1000mm.

[0011] Optionally, one right-angled side of the component body is provided with two rectangular protrusions, and the other right-angled side is provided with two rectangular grooves.

[0012] The prefabricated concrete block component provided by the utility model has at least the following beneficial effects:

[0013] 1. Since protrusions and grooves are respectively arranged on the two right-angled sides of the component body, four groups of the component bodies can be spliced ​​into a large square interlocking component. Each side of the square interlocking component has a dovetail groove, and a number of the square interlocking components can be spliced ​​together through the dovetail groove, thereby improving the integrity of the slope surface formed by the splicing of the prefabricated blocks in the horizontal direction, reducing the possibility of subsequent problems such as loosening or displacement of the prefabricated blocks, and forming a regular geometric pattern after splicing, which is also more beautiful.

[0014] 2. Since a number of through holes are provided on the component body, the component body forms a frame structure, which reduces the weight of the entire prefabricated block and the labor intensity of workers during transportation and assembly. At the same time, the energy dissipation effect of the slope surface on water waves can be improved, and the wave climbing height can be reduced. Soil-fixing and water-retaining plants are planted in the pores to achieve an organic combination of plant roots and slope protection, thereby improving the overall stability and safety of the slope protection.

[0015] 3. If local looseness or damage occurs later, specific parts can be repaired, which will reduce the cost of subsequent maintenance management. BRIEF DESCRIPTION OF THE DRAWINGS
