Description

Technical Field

[0001] The utility model relates to the technical field of underground pipelines, in particular to a municipal pipeline reinforcement structure. Background Art

[0002] Chinese patent document CN218348117U discloses an underground pipeline reinforcement structure, including a reinforced lower half hoop, a reinforced upper half hoop, a rotating shaft and a sealing ring. The upper surface of the reinforced lower half hoop is provided with a reinforced upper half hoop, a rotating shaft is installed between the reinforced lower half hoop and the reinforced upper half hoop, and the inner walls of the reinforced lower half hoop and the reinforced upper half hoop are both connected with sealing rings. In the underground pipeline reinforcement structure, the rotating bolt can drive the fixed plug rod to move horizontally through the linkage plate. When the fixed plug rod moves horizontally to the inside of the positioning hole, the reinforced lower half hoop and the reinforced upper half hoop can be fixed to the connection of the pipeline, and the connection is sealed by the sealing ring, so that the pipeline reinforcement structure can be sealed and installed conveniently and quickly. In this way, the pipeline connection can be sealed while reinforcing it, so as to prevent the connection from rusting due to groundwater erosion and extend the service life. The defects and shortcomings of this underground pipeline reinforcement structure are: (1) in actual use, when the underground soil is hard, the pipeline body will be squeezed and broken, resulting in high cost of use; (2) when the outer wall of the pipeline is filled with soil, the pipeline body is easily deformed by pressure, and the pressure resistance is poor, thus failing to achieve the best use effect; (3) the connection points at both ends of the pipeline are prone to loosening when under high pressure.

[0003] Therefore, there is an urgent need to provide a municipal pipeline reinforcement structure that can protect the pipeline body and prevent the pipeline body from being squeezed and ruptured. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific implementation methods. Figure 1 The orientation is used as a reference.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The present embodiment provides a municipal pipeline reinforcement structure, which is installed on the periphery of a transport pipeline 3, including a connecting plate 1, and a support sleeve 2 is respectively provided at both ends of the connecting plate 1, and the transport pipeline 3 is arranged on the support sleeve 2 (that is, the two ends of the transport pipeline 3 are respectively connected to a support sleeve 2), and a protective device is arranged on the periphery of the transport pipeline 3.

[0028] The protective device includes two symmetrically arranged mounting shells 4 and protective shells 5 arranged one by one corresponding to the mounting shells 4. The two mounting shells 4 are fixedly sleeved on the periphery of the transport pipeline 3. The protective shell 5 is located on the outside of the mounting shells 4 and has a semicircular structure. The inner side surface thereof is connected to the outer side surface of the mounting shell 4 through multiple first springs 6.

[0029] Combination Figure 4 As shown, a first support block 9 is arranged on the outer surface of the mounting shell 4, the end of the first support block 9 is gradually reduced, and a first inclined surface 10 is formed on the upper surface and the lower surface of the end of the first support block 9; a groove 7 is opened on the inner side surface of the protective shell 5 corresponding to the first support block 9, a guide rod 8 is arranged in the groove 7, and two second support blocks 11 are slidably arranged on the guide rod 8, and a second inclined surface 12 cooperating with the first inclined surface 10 is formed on one end of the two second support blocks 11 close to the first support block 9, and a second spring 13 is arranged between the side wall of the groove 7 and the opposite sides of the two second support blocks 11.

[0030] The working principle of the municipal pipeline reinforcement structure of this embodiment is as follows: when in use, the installation shell 4 and the protective shell 5 are first installed on the surface of the transport pipeline 3. When the transport pipeline 3 receives the stratum pressure, the protective shell 5 is stressed, and the first spring 6 is compressed to play a shock-absorbing role; at the same time, the first support block 9 squeezes the two second support blocks 11, so that the two second support blocks 11 move on the guide rod 8, and at the same time, the two second support blocks 11 squeeze the second spring 13, which further plays a shock-absorbing effect.

[0031] In this embodiment, dampers are provided in both the first spring 6 and the second spring 13. The purpose of providing the dampers is to further increase the shock absorbing effect of the first spring 6 and the second spring 13.

[0032] Furthermore, one end of the connecting plate 1 is provided with a concave tooth 101, and the other end of the connecting plate 1 is provided with a convex tooth 102, and the concave tooth 101 and the convex tooth 102 are mortise and tenon structures. During use, the convex tooth 102 of one municipal pipeline reinforcement structure can be inserted into the concave tooth 101 of another municipal pipeline reinforcement structure, so that the two municipal pipeline reinforcement structures are spliced ​​together, the length of the transport pipeline 3 is increased, and the connection strength of the two ends of the transport pipeline 3 is improved.

[0033] Combination Figure 2 , Figure 3 and Figure 5 As shown, both upper and lower sides of the two mounting shells 4 extend outward to form connecting blocks 14 . When the two mounting shells 4 are assembled together, adjacent connecting blocks 14 are fixedly connected by connecting components 15 .

[0034] Furthermore, the connection assembly 15 includes a plurality of bolts 16 and nuts 17. After the plurality of bolts 16 pass through the two connection blocks 14 in sequence, they are screwed together with the nuts 17, thereby fixing the connection blocks 14 of the two mounting shells 4 together. The bolts 16 and nuts 17 are used to achieve the effect of quickly disassembling and installing the protective device.

[0035] Furthermore, the connection assembly 15 further includes a fixing plate 18, and the bolts 16 are grouped in pairs, and the bolt heads of each group of bolts 16 are fixedly connected together through the fixing plate 18. The fixing plate 18 not only connects the bolt heads of the two bolts 16 together, but also acts as a bolt gasket, that is, it can increase the contact area and friction force, and protect the bolt rod.
