Description

Technical Field

[0001] This utility model belongs to the field of construction technology of fluidized solidified soil, and specifically relates to a pipeline device for construction of fluidized solidified soil. Background Technology

[0002] Fluidized solidified soil is a type of construction fill material that is formed by mixing soil, a solidifying agent, and water. It is suitable for backfilling deep and narrow spaces, similar to pits or trenches, in construction projects.

[0003] Currently, the placement of pipes for traditional pouring of fluidized solidified soil is rather arbitrary. Usually, the pipe outlet is placed on the edge of the trench opening. In this way, the fluidized solidified soil flowing out of the pipe outlet is prone to eroding the sidewalls of the trench, causing instability of the trench soil. Another method is to use a truck crane to suspend the flexible placing hose at the end of the iron pipe for pouring. Although this method can improve the flexibility of the pipe, it has high requirements for the bearing capacity of the stratum and the space of the work site. It is easily restricted by the site and cannot be moved at will. It can only allow the pipe to move within a small range to change the pouring position to avoid the accumulation of fluidized soil at the bottom of the trench. Therefore, it is not effective when pouring long trenches.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of two traditional pipeline layout methods for pouring fluidized solidified soil, which are prone to eroding the side walls of the pit and reducing the stability of the soil layer, and are easily restricted by the work site and cannot be fully applied to long pit backfilling operations. The invention provides a pipeline device for the construction of fluidized solidified soil.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0014] Preferably, the movable frame includes: a vertical plate and a horizontal plate, the vertical plates being a pair and facing each other, and the horizontal plate being located at the bottom between the two vertical plates to form a U-shaped space above the horizontal plate.

[0015] Preferably, the annular frame is rotatably disposed within the U-shaped space, and there is a gap between the bottom of the annular frame and the horizontal plate;

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0033] This embodiment aims to provide a pipeline device for the construction of fluidized solidified soil. Its main function is to avoid the erosion of the sidewalls of the pit during the pouring of fluidized solidified soil and to carry out efficient backfilling operations for long pits.

[0034] Reference Figure 1-6 The suspension rod 1 is horizontally positioned above and in the center of the pit, with its two ends located above the pit's edges on both sides. Both ends of the suspension rod 1 are radially welded with handles 5. A guide pipe 2 is hinged to the lower middle part of the suspension rod 1, with its opening facing the pit. The rotation direction of the guide pipe 2 is consistent with the axis of the suspension rod 1, ensuring that the guide pipe 2 does not tilt as the suspension rod 1 tilts. Both ends of the guide pipe 2 can serve as outlets. In actual use, the pipe is usually a flexible material distribution hose, and the head of the flexible material distribution hose is usually equipped with a pipe clamp to fit the opening of the flexible material distribution hose over the guide pipe 2 and fix it in place. The guide pipe 2 is arc-shaped, with both ends of its opening slightly inclined downwards.

[0035] Both ends of the suspension rod 1 are fixedly fitted with turntables 3. A ring frame 4 is fitted around the turntables 3. Rollers 6 are evenly distributed around the circumference of the turntables 3. The rollers 6 are embedded in the circumferential wall of the turntables 3, and some of the rollers 6 protrude outward to contact the inner wall of the ring frame 4, so that there is rolling friction between the turntables 3 and the ring frame 4, thereby reducing the rotational resistance of the turntables 3.

[0036] The turntable 3 has evenly distributed positioning grooves 7 on its circumference. These positioning grooves 7 are offset from the rollers 6. A positioning post 8 is inserted into the center of the top of the ring frame 4. The upper end of the positioning post 8 is equipped with a pull ring, and the lower end of the positioning post 8 is inserted into the positioning groove 7 to fix the rotation position of the turntable 3, thereby fixing the elevation angle of the guide pipe 2. Based on this, the elevation angle of the guide pipe 2 can be adjusted by continuously changing the rotation position of the turntable 3, thereby adjusting the pouring position of the fluidized solidified soil, so that the position of the entire device does not need to be moved frequently.

[0037] The ring frame 4 is rotatably mounted above the movable frame, and the rotation direction of the ring frame 4 is consistent with the axial direction of the suspension rod 1. The movable frame is placed on the edge of the pit, and the movement direction of the movable frame is consistent with the length direction of the pit to prevent it from falling into the pit. Specifically, the movable frame includes: vertical plates 9 and horizontal plates 10. There is a pair of vertical plates 9 arranged facing each other. The horizontal plates 10 are welded and fixed to the bottom between the two vertical plates 9 to form a U-shaped space above the horizontal plates 10. The ring frame 4 is rotatably mounted in the U-shaped space. There are rotating shafts protruding from the middle of both sides of the ring frame 4. The rotating shafts are inserted into the corresponding vertical plates 9. There is a gap between the bottom of the ring frame 4 and the horizontal plate 10 to provide rotation space for the ring frame 4. There are support shafts in the middle at both ends of the horizontal plate 10. The axial direction of the support shaft is consistent with the axial direction of the suspension rod 1. The support shaft is not shown in the figure because it is obscured by other structures. Rollers 11 are rotatably mounted on both ends of the support shaft through bearings. The bearings are interference-fitted with the support shaft. The rollers 11 are set at both ends of the horizontal plate 10 to ensure its stability.

[0038] Both sides of the ring frame 4 are provided with limiting frames to prevent the turntable 3 from detaching. Specifically, the limiting frames include an outer ring frame 12, an inner ring frame 13, and a roller 14. The outer ring frame 12 and the inner ring frame 13 are connected as one unit by multiple connecting rods (not shown in the figure) so that the roller 14 can be rotated and fitted onto the outside of the connecting rods. The roller 14 contacts the turntable 3 to reduce the rotational resistance of the turntable 3. The outer ring frame 12 and the inner ring frame 13 are centered on the turntable 3 so that the outer ring frame 12 is welded or bolted to the side of the ring frame 4. The width of the inner ring frame 13 is smaller than the thickness of the outer ring frame 12 so that the inner ring frame 13 corresponds to the turntable 3 but does not contact it, so as not to hinder the rotation of the turntable 3.

[0039] In actual use, first, fix the outlet of the fabric hose to one end of the guide pipe 2 using a pipe clamp. Then, hoist the device above the pit and gradually lower the moving frames on both sides of the pit to correspond to the two sides of the pit edge. If there is a certain height difference between the two sides of the pit edge, the device will adaptively adjust using the rotational relationship between the ring frame 4 and the two vertical plates 9. Figure 6 As shown, the fluidized solidified soil can then be poured into the pit. At this time, the guide pipe 2 will be in the center of the pit or close to the center of the pit, and there will be no scouring of the pit sidewalls. Every once in a while, the elevation angle of the guide pipe 2 can be adjusted to change the falling position of the fluidized soil. Alternatively, the device can be appropriately moved along the length of the pit to change the pouring position as needed to avoid serious accumulation of fluidized soil until the pouring is qualified.

[0040] The pipeline device provided in this embodiment can fix the pipeline in a suspended position above the pit, thereby ensuring that the pouring of the fluidized solidified soil will not erode the side wall of the pit. At the same time, this utility model can realize the traction of the pipeline to pour at different positions in the pit, which is very suitable for backfilling operations of long pits and has excellent results.
