[0030] A plurality of waste wood piles 4 are arranged in the landfill layer 2, the bottom end of the waste wood pile 4 is buried in the landfill layer 2, and the top end of the waste wood pile 4 extends vertically upward out of the top pavement of the landfill layer 2 to support the recycled board 3, thereby increasing the support strength of the recycled board 3, avoiding concave, ensuring the flatness of the constructed garden road, and improving the walking comfort.

[0031] The waste wood pile 4 is made of a peeled dead tree trunk, and a corrosion-resistant paint layer is coated on the outer surface of the waste wood pile 4 to increase the corrosion resistance and prolong the service life.

[0032] In order to enable the recycled board 3 to bear uniform force to increase the stability, the waste wood pile 4 needs to be uniformly buried in the landfill layer 2; therefore, the garden paving structure in the embodiment further comprises a positioning frame 5 buried in the landfill layer 2, the positioning frame 5 has a plurality of positioning insertion holes 6 for the waste wood pile 4 to be inserted during paving, thereby realizing the positioning arrangement of the waste wood pile 4 and ensuring the uniform arrangement of the waste wood pile 4 without the need for manual repeated measurement and correction of the position, thereby improving the paving accuracy and efficiency.

[0033] Specifically, the positioning frame 5 has a grid structure and a plurality of longitudinal and transverse intersecting rod bodies, a positioning portion 5a is formed at the intersection of adjacent two rod bodies, and the positioning insertion hole 6 is arranged at the positioning portion 5a, and the waste wood pile 4 is inserted into the positioning insertion hole 6; since the positioning insertion holes 6 on the positioning frame 5 are fixed and the spacing between the positioning insertion holes 6 is the same, each waste wood pile 4 inserted can be arranged in position, and the spacing between the waste wood piles 4 is ensured to be the same.

[0034] The size of the positioning frame 5 is set according to the size of the garden road to be paved; during paving, the waste wood pile 4 passes through the positioning frame 5 from the top to the bottom of the positioning frame 5 through the positioning insertion hole 6, and the waste concrete and the sand and crushed soil mixture are sequentially layered and filled between the waste wood piles 4, and the landfill layer 2 is formed after ramming, thereby completing the burial of the waste wood pile 4, and at this time, the recycled board 3 can be paved.

[0035] When the filling material is filled, the positioning frame 5 can move relative to the waste wooden pile 4 through the positioning hole 6 due to the loose state between the waste wooden pile 4 and the positioning hole 6 on the positioning frame 5, and it is easy to deviate and cannot be kept horizontal at the elevation position, so that the waste wooden pile 4 after being inserted is inclined and cannot vertically support the regenerated board 3, and the garden road after being stepped appears concave and uneven; therefore, the positioning frame 5 is provided with a locking mechanism at the positioning portion 5a, so that the waste wooden pile 4 can be locked and fixed after being inserted into the positioning hole 6.

[0036] The locking mechanism comprises an outer sleeve and an inner sleeve sleeved in the inner sleeve; the inner sleeve has a tapered peripheral wall portion, a through groove 702a is formed on the tapered peripheral wall, and the waste wooden pile 4 can be inserted into the inner sleeve; the outer sleeve is arranged on the top surface of the positioning portion 5a of the positioning frame 5 and communicates with the positioning hole, and the outer sleeve has a tapered inner peripheral wall 802 which can be axially moved relative to the tapered peripheral wall portion of the inner sleeve; when the inner sleeve moves axially from the top to the bottom of the outer sleeve relative to the outer sleeve, the waste wooden pile 4 can be locked by the tapered peripheral wall of the inner sleeve.

[0037] Specifically, the inner sleeve is an inner sleeve 7, and the outer sleeve is an outer sleeve 8; the inner sleeve 7 is sleeved in the outer sleeve 8, the inner sleeve 7 comprises a cylindrical inner sleeve pipe portion 701 and a tapered inner sleeve pipe portion 702 connected to the top end of the cylindrical inner sleeve pipe portion 701, the tapered inner sleeve pipe portion 702 gradually expands from the bottom end to the top end in the axial direction, and the bottom end of the waste wooden pile 4 is sequentially inserted through the tapered inner sleeve pipe portion 702 and the cylindrical inner sleeve pipe portion 701; the through groove 702a is arranged on the tapered inner sleeve pipe portion 702 and extends in the axial direction, and preferably, at least two through grooves 702a are arranged; the tapered inner sleeve pipe portion 702 and the cylindrical inner sleeve pipe portion 701 are integrally formed to form the inner sleeve 7; the diameter of the cylindrical inner sleeve pipe portion 701 of the inner sleeve 7 is greater than the diameter of the positioning hole 6.

[0038] The outer sleeve 8 is formed with sleeve openings at both axial ends, wherein the bottom sleeve opening of the outer sleeve 8 communicates with the positioning hole 6 on the positioning frame 5, and the inner sleeve 7 can be pressed into the outer sleeve 8 from the top sleeve opening of the outer sleeve 8 in the axial direction; the inner peripheral wall of the outer sleeve 8 is composed of two sections, including a cylindrical inner peripheral wall 801 and a tapered inner peripheral wall 802 connected to the top end of the cylindrical inner peripheral wall 801, the shape and size of the tapered inner peripheral wall 802 correspond to those of the tapered inner sleeve pipe portion 702, and the tapered inner peripheral wall 802 gradually expands from the bottom end to the top end in the axial direction; the tapered inner peripheral wall 802 of the outer sleeve 8 can abut against the outer peripheral wall of the tapered inner sleeve pipe portion 702, so that the tapered inner sleeve pipe portion 702 is shrunk.

[0039] When the inner sleeve 7 is pressed in, the tapered inner wall 802 of the outer sleeve 8 tightly abuts the outer wall of the tapered inner sleeve part 702, and since the tapered inner sleeve part 702 is formed with the split groove 702a, the tapered inner sleeve part 702 can be deformed to tightly grip the outer surface of the waste stump, thereby achieving locking and fixing of the waste stump.

[0040] The outer sleeve 8 is provided with a stop portion at the top of the sleeve opening, which is used to limit the inner sleeve 7 in the outer sleeve 8 after being pressed in, so as to maintain the locking state of the waste stump 4.

[0041] The stop portion on the outer sleeve 8 is an annular flange 803 arranged on the inner side of the top of the sleeve opening, which abuts the top end of the inner sleeve 7 after the inner sleeve 7 is completely pressed into the outer sleeve 8, thereby limiting the inner sleeve 7 in the outer sleeve 8; it should be noted that in the embodiment, the inner sleeve 7 is completely pressed into the outer sleeve 8, which means that the inner sleeve 7 moves axially relative to the outer sleeve 8, and when the top end of the inner sleeve 7 is below the top of the sleeve opening of the outer sleeve 8, it means that the inner sleeve 7 is completely pressed into the outer sleeve 8.

[0042] In the embodiment, the positioning frame 5, the outer sleeve and the inner sleeve are all formed by regenerating waste degradable plastic products, so as to gradually degrade in the landfill layer 2 after paving, and with the passage of time, the landfill layer 2 also gradually becomes more compact, which can completely fix the waste stump 4 without the need for continued positioning by the positioning frame 5, thereby fully utilizing the degradable plastic products and avoiding pollution of the environment.
