[0014] Figure 1 This is a schematic diagram of a settlement compensation device for small-diameter pipe joints.
[0015] Figure 2 for Figure 1 Enlarged view of section I in the middle. Detailed Implementation
[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] The embodiments of this utility model provide a settlement compensation device for small-diameter pipe joints, see [link to relevant documentation]. Figure 1 It includes a first support ring 12 and a second support ring 13. The two support rings are used on both sides of the interface when the settlement of the small-diameter pipe interface exceeds the allowable value, and the position of the pipe is adjusted to meet the construction standards.
[0018] See also Figure 1 The first support ring 12 is composed of two first half-rings, which are defined as the first left half-ring 2 and the first right half-ring 1. The first left half-ring end 2a and the first right half-ring end 1a are the hinge mounting ends of the two rings, and the first left half-ring end 2b and the first right half-ring end 1b are the adjustment ends of the two rings. The hinge mounting ends of the two first half-rings are connected by a first adjustable hinge 5, which allows the two first half-rings to rotate around the first adjustable hinge. The adjustment ends of the two first half-rings are provided with a first connector 7. The part of the first connector 7 that contacts the first half-ring can be cylindrical to improve the strength and stability of its own structure. The cylindrical end of the first connector 7 is provided with a flat extension section, such as a square extension, so as to facilitate good stacking with adjacent structures.
[0019] See also Figure 1 The second support ring 13 is composed of two second half rings, which are defined as the second left half ring 4 and the second right half ring 3. The second left half ring end 4a and the second right half ring end 3a are the hinge mounting ends of the two rings, while the second left half ring end 4b and the second right half ring end 3b are the adjustment ends of the two rings. The hinge mounting ends of the two second half rings are connected by the second adjustable hinge 6. The adjustment ends of the two second half rings are provided with a second connector 8. The second connector 8 is cylindrical in the position adjacent to the second half ring. The end of the cylindrical structure is a flat extension section, such as a block-shaped extension, so as to facilitate stacking with the flat extension section of the first connector.
[0020] It is important to note that the first and second connectors 8 must be coaxially distributed to meet construction requirements. The overlapping portions of the two connectors, after complete overlap, should ensure that the cylindrical structures of the first and second connectors are in a coaxial position. This guarantees that the settled pipe can be forcibly lifted to the standard construction position during the repositioning process. The flat structure of the rotation adjustment device installation position for the first and second connectors facilitates settlement correction while meeting the coaxial structural design requirements of the cylindrical structures of the first and second connectors.
[0021] Of course, rubber rings can be installed on the inner walls of the first support ring 12 and the second support ring 13. This structure can not only prevent the support rings from scratching and damaging the pipes, but also use the flexible structure of the rubber rings to protect against radial compression damage that occurs during the installation of the support rings.
[0022] It is worth mentioning that a rotary adjustment device 9 is provided between the first connecting member 7 and the second connecting member 8. This rotary adjustment device can force the adjacent pipes to return to the relative size range required for construction after the first half-ring and the second half-ring have fixed them. The rotary adjustment device 9 includes an adjusting screw 9a and an adjusting nut 9b that cooperates with the adjusting screw. Figure 2 It can be seen that, due to the forced tightening effect of the rotation adjustment device, the first and second connecting parts can be in a state of... Figure 2 As shown, under the forced external force of adjusting the screw and adjusting nut, the settling pipe is raised to the same height as the connecting pipe, and then the corresponding construction can be carried out.
[0023] See Figure 1 The hinge mounting ends of the first half ring and the second half ring have overlapping parts. This overlapping distribution is conducive to the rapid docking between the two. When the first adjustable hinge 5 and the second adjustable hinge 6 are made of bolts, the overlapping part can increase the contact area between the first half ring and the second half ring to meet the needs of improving the overall structural strength.
[0024] Considering the needs of on-site construction, the first support ring and the second support ring are detachably equipped with coaxially distributed constraint-type connecting rods. In this embodiment, two constraint-type connecting rods are used, namely the first constraint-type connecting rod 10 and the second constraint-type connecting rod 11, and corresponding mounting holes are distributed in their respective support rings.
[0025] The method of using this utility model is as follows: When it is found that the settlement of the small-diameter pipe interface exceeds the allowable value during construction, support ring a (first support ring) and support ring b (second support ring) are put on both sides of the interface, and the first adjustable hinge shaft 5 and the second adjustable hinge shaft 6 are tightened (since bolts are used, the bolts are directly screwed into the corresponding hinge shaft installation end of the support ring with a wrench to achieve good disassembly and assembly characteristics), so that the support ring is in contact with the outer wall of the pipe. At this time, the first connecting piece 7 and the second connecting piece 8 are not on the same horizontal line due to the settlement of the pipe. The pipe on both sides is temporarily made to meet the construction standard by turning the rotary adjustment device 9. At the same time, the first constraint connecting rod 10 and the second constraint connecting rod 11 are inserted to keep the pipe on the same straight line.
[0026] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
