[0028] Example 1:
[0029] Reference Figure 1-11 A slidable scraper for leveling a pipeline base comprises a T-shaped bracket 1, a trapezoidal scraper 2 is fixedly connected to the bottom of the T-shaped bracket 1, a positioning square wood 3 is fitted on the bottom of the T-shaped bracket 1, a second circular hole 4 is opened inside the positioning square wood 3, a first screw 5 is fitted on the inner wall of the second circular hole 4 and the inner wall of the T-shaped bracket 1, a first nut 6 is fitted on the bottom of the positioning square wood 3 and the upper surface of the T-shaped bracket 1, and the inner wall of the first nut 6 is threadedly connected to the surface of the first screw 5.
[0030] A third circular hole 7 is provided inside the positioning square wood 3, and a second screw 8 is fitted on the inner wall of the third circular hole 7. A second nut 9 is fitted on the side of the positioning square wood 3, and the inner wall of the second nut 9 is threadedly connected to the surface of the second screw 8. Through the cooperation of the second nut 9 and the second screw 8, the second screw 8 and the positioning square wood 3 can be disassembled. A horizontal steel pipe 10 is fitted on the side of the positioning square wood 3, and a right-angle fastener 11 is fixedly connected to the surface of the horizontal steel pipe 10, and a vertical steel pipe 12 is fixedly connected to the inner wall of the right-angle fastener 11. The horizontal steel pipe 10 must be placed outside the foundation pit to ensure that the vertical steel pipe 12 is evenly stressed and does not rotate. The vertical steel pipe 12 should be inserted into the soil for at least 50 cm. The horizontal steel pipe 10 and the vertical steel pipe 12 are fixed together by the right-angle fastener 11, and the horizontal steel pipe 10 and the vertical steel pipe 12 are perpendicular to each other. When the T-shaped bracket 1 is placed on the horizontal steel pipe 10, the moving trajectory of the T-shaped bracket 1 is restricted by the positioning square wood 3. At the same time, the second screw 8 is used to prevent the T-shaped bracket 1 from flipping during movement.
[0031] The T-shaped bracket 1 includes a horizontal square timber 101, and the bottom of the horizontal square timber 101 and the upper surface of the trapezoidal scraper 2 are fixedly connected with a vertical square timber 102. The front and rear sides of the trapezoidal scraper 2 are both inclined surfaces. The center of the trapezoidal scraper 2 is on the same vertical line as the center of the horizontal square timber 101. A first circular hole 103 is opened inside the horizontal square timber 101. The inner wall of the first circular hole 103 contacts the surface of the first screw 5, the upper surface of the positioning square timber 3 contacts the bottom of the horizontal square timber 101, and the bottom of the first nut 6 contacts the upper surface of the horizontal square timber 101. Through the cooperation of the first screw 5 and the first nut 6, the horizontal square timber 101 and the positioning square timber 3 can be disassembled and assembled. When the T-shaped bracket 1 moves horizontally, the concrete can be smoothed by the trapezoidal scraper 2 at the bottom of the T-shaped bracket 1.
[0032] Example 2:
[0033] Reference Figure 1-5 The surface of the second screw rod 8 is provided with a ball bearing 13, and the upper and lower sides of the horizontal steel pipe 10 are in contact with the surface of the ball bearing 13. By arranging the ball bearing 13 on the second screw rod 8, the user can move the T-shaped bracket 1 on the horizontal steel pipe 10 more smoothly.
[0034] Example 3:
[0035] Reference Figure 1-9A groove 14 is provided on the upper surface of the horizontal square timber 101, and a traction rope 15 is fitted on the inner wall of the groove 14. The groove 14 is located in the middle of the horizontal square timber 101, and the depth of the groove 14 is greater than the diameter of the traction rope 15. One end of the traction rope 15 is fixedly connected to the limiting column 16, and a U-shaped column 17 is fixedly connected to the bottom of the horizontal square timber 101. The inner wall of the U-shaped column 17 contacts the surface of the limiting column 16. Through the cooperation of the limiting column 16 and the U-shaped column 17, the traction rope 15 and the T-shaped bracket 1 can be quickly disassembled and assembled. At the same time, when the traction rope 15 is inserted into the groove 14, the traction rope 15 can be positioned by the groove 14, and the limiting column 16 will not slide from the U-shaped column 17.
[0036] In the present invention, when the user uses the device, he first constructs the pipeline cushion layer and ties the pipeline foundation steel bars. After the construction is completed, the vertical steel pipes 12 are erected, and one vertical steel pipe 12 is placed every 5 meters. Then, the appropriate height is measured and a line is marked on the vertical steel pipe 12 with a marker. Then, the horizontal steel pipe 10 is fixed to the vertical steel pipe 12 through the right-angle fastener 11, and the ball bearing 13 closest to the horizontal square wood 101 is in contact with the horizontal steel, so that the bottom of the horizontal square wood 101 is flush with the marked line on the vertical steel pipe 12.
[0037] Then, the ball bearing 13 farthest from the horizontal square timber 101 is fixed to the positioning square timber 3 through the cooperation of the second screw rod 8 and the second nut 9, and the ball bearing 13 prevents the T-shaped bracket 1 from flipping over during movement.
[0038] Then, the limiting column 16 is inserted into the U-shaped column 17, and the traction rope 15 is inserted into the groove 14. Then, two users pull the traction rope 15 to move the trapezoidal scraper 2, and the concrete is smoothed by the moving trapezoidal scraper 2. After the construction on one side is completed, the other side is constructed in reverse, and the overlapping part is not less than 1 / 3 of the scraper width, until the entire surface is completed, and the construction is carried out twice continuously.
