Description

Technical Field

[0001] The utility model relates to the technical field of ditch slope protection, in particular to an anti-freezing-heaving ditch slope protection block Background Art

[0002] In order to develop agriculture and for production and living, a large number of water conveyance and irrigation channels and drainage channels have been built everywhere. The current common forms of ditch slope protection are concrete lining or laying gabions, etc. Concrete lining can prevent the soil from being scoured. However, whether it is a water conveyance channel or a drainage channel, in areas with strong frost heaving, the frost heaving phenomenon at the bottom of the ditch is obvious. The concrete slab is prone to cracks and bulges and falls off, affecting normal use; although laying gabion slope protection is convenient for construction, in areas with soft soil, it will cause serious soil erosion and silt up the ditch, and a large amount of manpower and financial resources need to be invested in maintenance. Therefore, it is necessary to research an anti-freezing-heaving ditch slope protection block to solve the above problems Content of the Utility Model

Detailed implementation mode

[0016] The present utility model will be further described below in conjunction with the accompanying drawings:

[0017] As Figures 1 to 4 shown, an anti-freezing heaving ditch slope protection block includes a plurality of groups of left corner blocks 01, right corner blocks 02 and general-purpose blocks 03. The left end of the left corner block 01 is provided with a left splicing boss 011, and the left splicing boss 011 faces upward to the left. The right end of the left corner block 01 is provided with a middle splicing boss 012. The right end of the right corner block 02 is provided with a right splicing boss 021, and the right splicing boss 021 faces upward to the right. The left end of the right corner block 02 is provided with a middle splicing groove 022. The two ends of the general-purpose block 03 are respectively provided with a general-purpose boss 031 and a general-purpose groove 032. More than one group of general-purpose blocks 03 are arranged on the left side of the left corner block 01. A plurality of groups of general-purpose blocks 03 are spliced end to end in sequence through the general-purpose boss 031 and the general-purpose groove 032. The lowermost general-purpose block 03 is spliced with the left splicing boss 011 through the general-purpose groove 032. More than one group of general-purpose blocks 03 are arranged on the right side of the right corner block 02. The lowermost general-purpose block 03 is spliced with the right splicing boss 021 through the general-purpose groove 032. More than one group of general-purpose blocks 03 are arranged between the left corner block 01 and the right corner block 02. A plurality of groups of general-purpose blocks 03 are spliced end to end in sequence along the transverse direction through the general-purpose boss 031 and the general-purpose groove 032. The leftmost general-purpose block 03 is spliced with the middle splicing boss 012 through the general-purpose groove 032. The rightmost general-purpose block 03 is spliced with the middle splicing groove 022 through the general-purpose boss 031. A plurality of groups of left corner blocks 01, right corner blocks 02 and general-purpose blocks 03 are abutted against each other in multiple rows longitudinally.

[0018] The universal blocks 03 on the left and right sides are selected in specific quantities according to the height of the water channel and are respectively placed on the left and right sides of the water channel. Since the left splicing boss 011 and the right splicing boss 021 are inclined, the universal blocks 03 on both sides also extend obliquely and press tightly on the gravel on both sides. According to the width of the water channel, one group or multiple groups of universal blocks 03 are selected and stacked between the left corner block 01 and the right corner block 02. Of course, if the sum of the lengths of the left corner block 01 and the right corner block 02 is exactly close to the width of the water channel, the universal blocks 03 may not be added, and the left corner block 01 and the right corner block 02 are directly spliced to form a slope protection structure for the water channel. The length of the universal block 03 can be not unique, so as to be flexibly selected to adapt to water channels of various widths. The advantages of this design are as follows: It is built with spliced blocks, leaving slight gaps between the blocks, which can effectively resist cracking caused by frost heaving; the blocks are arranged neatly and tightly, which can effectively prevent the erosion and loss of water and soil; it can flexibly select different quantities of universal blocks 03 for stacking according to water channels of various widths and height dimensions, and the construction is convenient and fast; during maintenance, individual damaged blocks can be replaced, and the maintenance is convenient and the maintenance cost is low.

[0019] A first limiting boss 013 is provided at the front end of the left corner block 01, and a first limiting groove matching the first limiting boss 013 is provided at the rear end. Two adjacent groups of left corner blocks 01 in the front and rear are spliced through the first limiting boss 013 and the first limiting groove. A second limiting boss 023 is provided at the front end of the right corner block 02, and a second limiting groove matching the second limiting boss 023 is provided at the rear end. Two adjacent groups of right corner blocks 02 in the front and rear are spliced through the second limiting boss 023 and the second limiting groove. A third limiting boss 033 is provided at the front end of the universal block 03, and a third limiting groove matching the third limiting boss 033 is provided at the rear end. Two adjacent groups of universal blocks 03 in the front and rear are spliced through the third limiting boss 033 and the third limiting groove.

[0020] Through the mutual cooperation of the limiting boss and the limiting groove, the adjacent blocks in the front and rear are limited to each other in the vertical direction, avoiding obvious bulging or subsidence of the blocks due to changes in the surface of the gravel.

[0021] The left splicing boss 011, the middle splicing boss 012, the right splicing boss 021, the universal boss 031, the first limiting boss 013, the second limiting boss 023 and the third limiting boss 033 are all trapezoidal bosses, and the middle splicing groove 022, the universal groove 032, the first limiting groove, the second limiting groove and the third limiting groove are all trapezoidal grooves. The trapezoidal boss and the trapezoidal groove are convenient for operation during splicing and also convenient for processing during manufacturing. Of course, they can also be set as arc bosses and arc grooves or other splicing shapes.

[0022] There is a gap after the trapezoidal boss and the trapezoidal groove are spliced, which can facilitate the splicing operation and further resist the frost heaving phenomenon.

[0023] The working principle of this embodiment:

[0024] The specific number of the universal blocks 03 on the left and right sides is selected according to the height of the water channel and are respectively placed on the left and right sides of the water channel. Since the left splicing boss 011 and the right splicing boss 021 are inclined, the universal blocks 03 on both sides also extend obliquely and press tightly on the gravel on both sides. According to the width of the water channel, one group or multiple groups of universal blocks 03 are selected and stacked between the left corner block 01 and the right corner block 02. Of course, if the sum of the lengths of the left corner block 01 and the right corner block 02 is exactly close to the width of the water channel, the universal blocks 03 can also not be added, and the left corner block 01 and the right corner block 02 are directly spliced to form a water channel slope protection structure. The length of the universal block 03 can be not unique, so as to be flexibly selected and adapted to various water channel widths.

[0025] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
