Embodiment 1

[0057] Embodiment one sees Figure 1-8 As shown, an embedded-type pipeline internal support reinforcement system includes at least two reinforcement ring supports arranged along the circumference of the pipeline 20 to be strengthened.

[0058] The reinforced ring bracket includes a main body made of stainless steel, and the main body includes a first component 1 , a second component 2 , a first arc-shaped connecting piece 3 , a main body connecting bolt 4 and an adapter block 5 . The first component 1 is a semi-circular arc piece adapted to the curvature along the inner wall of the pipeline to be reinforced, one end of which is the first connecting end 11 and the other end is the first fitting end 12 . The second component 2 is a semi-circular arc piece adapted to the curvature along the inner wall of the pipeline to be reinforced, one end of which is the second connecting end 21 and the other end is the second fitting end 22 .

[0059] The first arc-shaped connecting piece 3...

Embodiment 2

[0077] Embodiment two see Figure 11-12 As shown, the difference from Embodiment 1 is that this embodiment is a full-length stent. The main body and the wing plate form plug boards 14a and slots 14b that are arranged alternately along the circumferential interval of the reinforced ring bracket and are adapted in size. The plug plate 14a of the reinforcement ring support is inserted in the slot 14b of the front reinforcement ring support, the plug plate 14a of the front reinforcement ring support is inserted in the slot 14b of the rear reinforcement ring support, and the front reinforcement ring support The steel cylinder is integrally connected with the rear truss reinforcement ring bracket socket and closed, and the deformation of the steel cylinder along the pipeline direction and radially outward is restrained, and the radially inward direction is free.

[0078] In this embodiment, five wings are arranged on the main body, two and a half lines are arranged on the upper win...

Embodiment 3

[0080] Embodiment three see Figure 11 and Figure 13 As shown, different from the second embodiment, the wing plate 14 is provided with a wing plate hole 8, and the front reinforcement ring bracket and the rear reinforcement ring bracket are fixedly connected by a second arc-shaped connecting piece 19, The arc of the second arc-shaped connecting piece 19 is adapted to the arc of the inner wall of the main body, and the second arc-shaped connecting piece is arranged circumferentially.

[0081] Therefore, in the reinforcement method of this embodiment, the position corresponding to the flange hole 8 on the second arc-shaped connecting piece 19 is all provided with a second bolt hole 17, and the front reinforcement ring bracket and the rear reinforcement ring bracket correspond to each other. The inner wall of the wing plate 14 is bolted through the wing plate connecting bolts 18 passing through the second bolt hole 17 and the wing plate hole 8 in sequence. The steel cylinder ...

Abstract

The invention discloses an embedded pipeline inner support reinforcing system and a reinforcing method thereof. The reinforcing system comprises a reinforced circular ring support, wherein the reinforced circular ring support comprises a main body, and the main body comprises a first assembly, a second assembly, a first arc-shaped connecting piece, a main body connecting bolt and an adaptive block; and one end of the first assembly is fixedly connected with one end of the second assembly, and the other end of the first assembly is connected with the other end of the second assembly to form a complete closed circular ring through coordination of a first limiting clamping block, a second limiting clamping block and the adaptive block. The reinforcing method thereof comprises the following steps of strand pipeline current situation verification, design and manufacture of the reinforced circular ring support, first assembly installation, second assembly installation, limiting clamping groove expansion of an expansion device and adaptive block embeddedness and the like. According to the embedded pipeline inner support reinforcing system and the reinforcing method thereof, a damaged pipeline is subjected to structural non-excavation repair, radial tension enables the support to be tightly attached to a to-be-reinforced structure, the new and old structures cooperatively work to makeup irregular change of the section size of the damaged pipeline, so that reinforcing quality is guaranteed, the repairing process is simplified, and the service life of the pipeline is prolonged.

Description

technical field [0001] The invention belongs to the field of underground pipeline reinforcement, in particular to an embedded inner support reinforcement system and a construction method thereof. Background technique [0002] Underground pipelines are the lifeline of urban operation, but due to different economic and construction levels in different periods, the quality of underground pipelines varies greatly. With the growth of time, many underground pipelines are approaching the end of their service life, or even "overdue service". This problem is more obvious in old urban areas. In recent years, road subsidence accidents have occurred frequently, and the reasons are often caused by the leakage, damage, or even collapse of old underground pipelines. [0003] Most of the underground pipelines are located under the main traffic roads in the city, which cannot be excavated and repaired on a large scale. Therefore, trenchless repair is currently the most simple and economica...
