Description

Technical Field

[0001] This application relates to the technical field of pipeline construction, and particularly relates to a mortar filling structure for the outer joint of a pipeline. Background Art

[0002] Prestressed concrete cylinder pipe, abbreviated as PCCP, is widely used in projects such as long-distance water conveyance and urban water supply and drainage due to its high strength, durability, and economy. The installation quality of PCCP directly affects the operation efficiency and safety of the entire system, and the outer joint filling at the pipe joint is a key link to ensure the pipeline sealing and structural stability.

[0003] Traditional outer joint filling methods usually use mortar mixed on-site and manually fill the mortar into the outer joint of the pipeline. However, since the pipeline is laid in a foundation pit and the space at the bottom of the pipeline joint is narrow and difficult for construction workers to reach, it leads to high labor intensity, low construction efficiency, and the mortar is prone to falling off during the filling process, thus affecting the filling quality.

[0004] There is a current outer joint filling method for pipelines that uses a band to wrap the bottom of the outer joint of the pipeline interface and then performs mortar perfusion. This method has the advantages of fast construction speed and simple operation compared with traditional manual filling. However, due to space limitations and the obstruction of the band, it is difficult to achieve effective vibration, especially in positions such as the bottom of the pipeline that are difficult to observe and operate, which may result in a loose internal structure of the mortar after perfusion and affect its bearing capacity and sealing effect. Summary of the Utility Model

[0005] The purpose of this application is to provide a mortar filling structure for the outer joint of a pipeline to solve the problem of the loose internal structure of the mortar poured into the outer joint of the pipeline.

[0007] A mortar filling structure for the outer joint of a pipeline includes a band disposed directly below the outer joint at the adjacent two pipeline joints. The band is wrapped around the outer walls of the adjacent two pipelines through a fixing component. A vibrating rope is disposed between the outer joint and the band, and both ends of the vibrating rope are located outside both ends of the band.

[0008] Further, both ends of the vibrating rope are respectively connected with handles, and at least one of the handles is detachably connected to the vibrating rope.

[0009] Further, the handle is a ring structure.

[0010] Further, the fixing component includes a tensioning member disposed above the pipeline, and the tensioning member is respectively connected with both ends of the band through two groups of tensioning ropes.

[0011] Further, connection parts connected to the tensioning rope are arranged at both ends of the strap.

[0012] Further, the tensioning rope is connected to the connection part through a hook.

[0013] Further, the tensioning member includes a turnbuckle or a ratchet pawl wire puller.

[0014] Further, the length of the strap is L 1 , and the perimeter of the outer seam is L 2 ; wherein,

[0015] Further, the width of the strap is W 1 , and the width of the outer seam is W 2 ; wherein, 4W 2 ≤W 1 ≤8W 2 .

[0016] Further, the strap includes soft iron sheet or rubber sheet.

[0017] Advantages of this application:

[0018] The pipeline outer seam mortar filling structure provided by the embodiment of this application uses the fixing assembly to fix the strap on the pipeline, so that the strap wraps around the bottom of the outer seam at the adjacent two pipeline joints, and then mortar can be poured into the outer seam to prevent the mortar from falling off during the pouring process; during this process, by pulling the vibrating rope back and forth, it plays a role in vibrating the mortar in the outer seam, which can not only eliminate the air bubbles in the mortar, improve the uniformity of mortar pouring, but also increase the bonding effect of the mortar, improve the tightness of the internal structure of the mortar, ensure its bearing capacity and sealing effect, and also reduce the setting time of the mortar and improve the construction efficiency.

[0037] See Figure 1 、 Figure 2, a mortar filling structure for the outer seam of a pipeline provided by an embodiment of the present application, includes a belt 12 disposed directly below the outer seam 11 at the joint of two adjacent pipelines 10. The belt 12 is wrapped around the outer walls of the two adjacent pipelines 10 through a fixing assembly 13. A vibrating rope 14 is disposed between the outer seam 11 and the belt 12, and both ends of the vibrating rope 14 are located outside both ends of the belt 12.

[0038] See Figure 1 , during the construction of the pipeline 10, when two adjacent pipelines 10 are assembled, an outer seam 11 is formed at their joint; wherein, mortar is filled in the outer seam 11. See Figure 1 , Figure 2 , the belt 12 is a strip-shaped structure, which is used to be fixed at the bottom of the pipeline 10 through the fixing assembly 13 and fit with the outer wall of the pipeline 10 to cover the outer seam 11; after the belt 12 is fixed on the pipeline 10, a filling space is formed between the belt 12 and the inner wall of the outer seam 11. The vibrating rope 14 is disposed in this filling space and extends along the circumferential direction of the outer seam 11, and both ends of the vibrating rope 14 respectively extend outside both ends of the belt 12 for an operator to hold. During the mortar pouring process, the operator can hold both ends of the vibrating rope 14 and pull the vibrating rope 14 back and forth to vibrate the mortar.

[0039] See Figure 3 , the filling method of the mortar filling structure for the outer seam of the pipeline provided by the embodiment of the present application includes the following steps: after several pipelines 10 are laid in the foundation pit, first dispose the vibrating rope 14 in the outer seam 11, then dispose the belt 12 below the joint of two adjacent pipelines 10. After adjusting the position of the belt 12, fix the belt 12 on the pipeline 10 through the fixing assembly 13 so that the belt 12 fits with the outer wall of the pipeline 10 and covers below the outer seam 11; pour mortar 16 into the outer seam 11, and the mortar 16 flows downward under its own gravity and fills the outer seam 11. During this process, the operator holds both ends of the vibrating rope 14 and pulls the vibrating rope 14 back and forth to vibrate the mortar 16 and increase the adhesiveness of the mortar 16; after the mortar pouring and vibrating are completed, pull out the vibrating rope 14. After the mortar 16 solidifies, remove the fixing assembly 13 and the belt 12, and sprinkle water on the mortar 16 in the outer seam 11 for curing.

[0040] The mortar filling structure for the outer seam of the pipeline provided by the embodiment of the present application uses the fixing component 13 to fix the wrapping belt 12 on the pipeline 10, so that the wrapping belt 12 wraps around the bottom of the outer seam 11 at the joint of two adjacent pipelines 10. Then, mortar can be poured into the outer seam 11 to prevent the mortar from falling off during the pouring process. During this process, by pulling the vibrating rope 14 back and forth, the mortar in the outer seam 11 can be vibrated, which can not only eliminate the air bubbles in the mortar, improve the uniformity of mortar pouring, but also increase the bonding effect of the mortar, improve the tightness of the internal structure of the mortar, ensure its bearing capacity and sealing effect, and also reduce the setting time of the mortar and improve the construction efficiency.

[0041] During the process of mortar pouring, the operator can directly hold both ends of the vibrating rope 14 and pull the vibrating rope 14 back and forth to vibrate the mortar. In some embodiments, referring to Figure 2 , handles 15 are respectively connected to both ends of the vibrating rope 14, and at least one handle 15 is detachably connected to the vibrating rope 14. Exemplarily, the handle 15 is in a ring structure or a strip structure. During the process of mortar pouring, the operator can hold the handle 15 to pull the vibrating rope 14 back and forth to vibrate the mortar. By setting the handle 15, a better grasping feeling can be provided for the operator, so that the operator is not easy to slip when pulling the vibrating rope 14 back and forth, increasing safety; when the operation time is long, the handle 15 can also disperse the pressure on the operator's hand, reducing hand fatigue and possible injuries. By setting at least one handle 15 to be detachably connected to the vibrating rope 14, the handle 15 can be removed after vibration, which is convenient for pulling out the vibrating rope 14 from the mortar to realize the reuse of the vibrating rope 14. The vibrating rope 14 can be made of steel wire rope, and the steel wire rope has a large structural strength, which can avoid situations such as fracture during use.

[0042] The fixing component 13 can include fine steel wires or cloth belts. After the wrapping belt 12 fits against the outer wall of the pipeline 10, the wrapping belt 12 can be wound and fixed on the pipeline 10 with fine steel wires and cloth belts. In some embodiments, referring to Figure 1 、 Figure 2 , the fixing component 13 includes a tensioning member 131 arranged above the pipeline 10, and the tensioning member 131 is respectively connected to both ends of the wrapping belt 12 through two groups of tensioning ropes 132. During operation, the two groups of tensioning ropes 132 are tightened by the tensioning member 131, so that the wrapping belt 12 closely fits against the outer wall of the pipeline 10.

[0043] Exemplarily, each group of tensioning ropes 132 can include two tensioning ropes 132. The tensioning ropes 132 can be made of steel wire rope, which can ensure the installation structural strength of the wrapping belt 12 while ensuring tension, so as to avoid fracture during the mortar pouring process.

[0044] In some embodiments, referring to Figure 1, connection parts 121 connected to the tensioning rope 132 are provided at both ends of the strap 12. The connection part 121 can be a connection hole penetrating through the strap 12 or a hook hanging member connected to the strap 12. For the convenience of quickly connecting the tensioning rope 132 and the connection part 121, the tensioning rope 132 is connected to the connection part 121 through a hook.

[0045] In some embodiments, the tensioning member 131 may include a turnbuckle. During operation, the lead screw is used for telescoping to tighten the tensioning rope 132 so that the strap 12 closely adheres to the outer wall of the pipeline 10. In some embodiments, the tensioning member 131 may include a ratchet and pawl wire puller. The ratchet and pawl wire puller may adopt an existing structure and can be directly purchased on the market. Due to the anti-reverse function of the pawl, the tensioning rope 132 can be gradually wound around the ratchet roller to tighten the tensioning rope 132 so that the strap 12 closely adheres to the outer wall of the pipeline 10. In other embodiments, the tensioning member 131 may further include a chain block, etc.

[0046] In some embodiments, the length of the strap 12 is L 1 , and the perimeter of the outer seam 11 is L 2 ; wherein, When the strap 12 is fixed, a grouting port can be formed between both ends of the strap 12 to facilitate the pouring of mortar.

[0047] In some embodiments, the width of the strap 12 is W 1 , and the width of the outer seam 11 is W 2 ; wherein, 4W 2 ≤W 1 ≤8W 2 . After the strap 12 is fixed, while covering the outer seam 11, it also leaves a width that closely adheres to the outer wall of the pipeline 10, which can prevent the leakage of mortar during the pouring process.

[0048] In some embodiments, the strap 12 may include soft iron sheet or rubber sheet. The soft iron sheet has a certain strength, is not easily damaged, can better bear the weight of the mortar, and avoids the problem of mortar leakage caused by damage. The rubber sheet is light in weight, has good wear resistance, and low cost. Of course, the strap 12 may also adopt other existing structures, which are not specifically limited herein.

[0049] The above is only a preferred embodiment of the present application, and does not impose any form of limitation on the present application. According to the technical essence of the present application, any simple modification, equivalent replacement, and improvement made to the above embodiments within the spirit and principle of the present application still fall within the protection scope of the technical solution of the present application.
