And finishing the pouring construction of the road concrete layer.
It should be noted that, when inserting the above-mentioned sheet-like pile member, the worker may first grasp the grip portion 1a with his/her hand to lift the sheet-like pile member to the position where the formwork is inserted in the mat D, which has been previously lined, and then press the tread portion 1b downward with his/her foot to insert the pile head 2 into the mat D so that the member is vertically fixed (if the mat D is soft, the member may be further fixed with a proper amount of concrete). And after the concrete layer A is poured, covering soil on the outer side of the pile-bearing plate-shaped component and compacting to form a road shoulder, and paving a road surface layer on the concrete base layer A. The obvious difference between the road paved by the method and the existing road is that the left side, the right side and the middle of the concrete layer A are all inserted with the plate-shaped members with piles.
If the application occasion of the sheet-shaped member with the pile in the embodiment is a road with a narrow width (for example, a single-lane rural road), since the concrete layer a of the whole road is formed by one-time casting without overlapping steel bars, it is not necessary to provide the reinforcement penetrating hole 1c on the member body 1, the construction mode of the concrete layer a is much simpler than the construction mode of separately casting the concrete layer a into the left part and the right part, and the construction process is as follows: firstly, inserting sheet-shaped components with piles into two sides of a concrete layer A to be poured, splicing all the sheet-shaped components with piles side by side along the extending direction of a road, and inserting pile heads 2 into a cushion layer D or roadbed soil below the sheet-shaped components with piles, so that all the sheet-shaped components with piles are vertically fixed; and then pouring concrete into the concrete pouring area between the two rows of the pile plate-shaped members, and forming a concrete layer A after the poured concrete is solidified.
As can be seen from fig. 2 and 3, the overall construction of the staked plate-like members used in the above embodiments is very simple. Because the grasping part 1a and the treading part 1b are arranged on the member body 1, and the pile head 2 with the pile tip is arranged below the member body 1, during on-site construction, a sheet-shaped member with the pile can be manually inserted by workers to replace the existing steel mould. In addition, as the pile-bearing plate-shaped member does not need to be demolded after the pile-bearing plate-shaped member is adopted, the outer side of the pile-bearing plate-shaped member can be immediately covered with soil and compacted to form a road shoulder after concrete pouring is finished, and the road laying period can be greatly shortened. Finally, because the pile-carrying plate-shaped component has smaller size (can be manually held and lifted), the pile-carrying plate-shaped component can be used for moulding to form smoother road turning radian, the construction is more flexible, and the road appearance is better.
The above embodiments are preferred implementations of the present invention, and the present invention can be implemented in other ways without departing from the spirit of the present invention.
