Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense wall reinforcement, in particular to a later stage pipe penetration structure of a civil air defense concrete wall. Background Art

[0002] With the development of urban construction and the change of people's lifestyle, many completed civil air defense basement projects will inevitably increase various supporting pipelines due to the need to add new equipment. When the original reserved pipeline channel is insufficient, it is often necessary to add pipeline casings to the existing civil air defense walls. In this process, it is necessary to drill holes in the original protective walls and then cast them for the second time. It is necessary to fully consider the structural bearing capacity and airtightness requirements of the protective walls after adding the casing. In addition, the commonly used methods in the actual implementation process often have problems such as large concrete excavation volume and the original force being cut off and needing reinforcement.

[0003] Chinese patent CN216429131U discloses a kind of existing civil defense wall opening plugging and reinforcement structure, including a closed sleeve arranged in the civil defense wall opening, the closed sleeve is set outside the pipeline and located between adjacent vertical steel bars, the closed sleeve is tightly attached to the outside of the closed sleeve, and the two ends of the restored steel bars are double-sidedly welded to the stressed steel bars that are interrupted at the civil defense wall opening; the closed sleeve is evenly spaced with closed ribs; the gap between the civil defense wall and the closed sleeve is densely poured with grouting material; the gap between the closed sleeve and the pipeline is densely filled with linseed oil and asbestos cement. The utility model is a kind of existing civil defense wall opening plugging and reinforcement structure, which adopts a closed sleeve to make the new and old materials seamlessly connected, so as to ensure the airtightness of the civil defense wall; it is flexible and changeable, not limited by the on-site environment, and has strong adaptability.

[0004] However, this technical solution requires expanding the original opening a little further outward to implant new steel bars and subsequently overlap or weld the severed steel bars in the original opening for reinforcement. This operation increases the area of ​​the opening, which will lead to structural instability and poor airtightness of the wall, thereby reducing the bearing capacity of the entire wall and affecting its use. In addition, the process is cumbersome and inconvenient to use, affecting work efficiency. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies of the prior art and provide a later-stage pipe penetration structure for a civil air defense concrete wall, which can firmly fix the casing on the wall through the steel plate on the casing and the reinforcement structure outside the casing, thereby solving the problem of unstable wall structure caused by excessively large openings in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A later-stage pipe-penetrating structure for a civil air defense concrete wall comprises: a wall body and a sleeve arranged in the wall body for penetrating pipelines, the sleeve comprises: a plurality of steel plates and a plurality of wall-penetrating pipes penetrating the steel plates, the pipelines pass through the wall-penetrating pipes, the steel plates are respectively arranged closely on both sides of the wall body, and a reinforcement structure is arranged on the periphery of the sleeve.

[0008] Preferably, the reinforcement structure includes: a plurality of transverse reinforcing ribs and a plurality of longitudinal reinforcing ribs, and the transverse reinforcing ribs pass through the anchor holes on the wall and are welded to the longitudinal reinforcing ribs.

[0014] Preferably, the longitudinal reinforcement ribs are arranged on the outer side of the steel plate.

[0015] Preferably, a plurality of air holes are provided on the steel plate.

[0016] The beneficial effects of the utility model are:

[0017] (1) The utility model covers the opening with a steel plate, combines it with a reinforcement structure laid on the periphery of the steel plate, and then fills the gaps in the wall with concrete. This process does not require a separate expansion of the opening, only a smaller opening size is required, which reduces the amount of concrete excavation and does not require the original steel bars to be cut off and then welded, thereby ensuring the integrity of the original stress-bearing steel bars to the greatest extent, thereby reducing damage to the structural concrete and ensuring the stability of the wall structure.

[0018] (2) The utility model completely blocks and fills the hole with steel plates and concrete, and then fills a layer of concrete on the outer periphery of the steel plates to form a closed ring structure of three pieces of concrete and two pieces of steel plates, thereby ensuring the airtightness of the wall, preventing cracks or falling off of the wall, and ensuring its bearing strength.

The concrete construction is convenient, low-cost and highly feasible.

[0020] In summary, the utility model has the advantages of good wall stability and airtightness, more stable and firm wall, convenient construction, low cost and high feasibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment 1

[0031] like Figure 1-5 As shown, this embodiment provides a later pipe penetration structure of a civil air defense concrete wall, including: a wall 1 and a sleeve 2 arranged in the wall 1 for penetrating a pipeline 3, the sleeve 2 including: a plurality of steel plates 21 and a plurality of wall-penetrating pipes 22 penetrating the steel plates 21, the pipeline 3 passes through the wall-penetrating pipes 22, the steel plates 21 are respectively arranged closely on both sides of the wall 1, and a reinforcement structure 4 is arranged on the periphery of the sleeve 2, the steel plates 21 cover the wall 1, thereby ensuring the airtightness of the wall 1, and the operation is simple, the installation is convenient, and the work efficiency can be improved. The steel plate 21 is preferably a 6mm hot-dip galvanized steel plate 21, which can be quickly welded and its strength can be guaranteed.

[0032] Among them, the reinforcement structure 4 includes: a plurality of transverse reinforcement ribs 41 and a plurality of longitudinal reinforcement ribs 42. The transverse reinforcement ribs 41 pass through the anchor holes 11 on the wall 1 and are welded to the longitudinal reinforcement ribs 42. The transverse reinforcement ribs 41 and the longitudinal reinforcement ribs 42 are preferably steel bars. A plurality of staggered weldings are formed to form a grid shape, covering the outside of the steel plate 21. There is no need to cut off the original steel bars in the wall 1. Only the transverse reinforcement ribs 41 and the longitudinal reinforcement ribs 42 are added to the original steel bars, thereby ensuring the integrity of the original load-bearing steel bars to the greatest extent, avoiding the need for subsequent lap joints or welding connections after cutting the steel bars, which can both ensure the bearing capacity requirements and reduce the size of the opening.

[0033] At the same time, the reinforcement structure 4 and the wall 1 are filled with concrete 43, which ensures the airtightness between the reinforcement structure 4 and the wall 1, and the concrete 43 has a good sealing effect, making the structure between the reinforcement structure 4 and the wall 1 more compact without any gap, making the entire wall 1 more stable and firm.

[0034] In this embodiment, a hole 12 adapted to the sleeve 2 is drilled on the wall 1. Since the steel plates 21 are closely arranged on both sides of the wall 1, only a smaller opening size is needed to drill the hole 12, and there is no need to expand the hole 12, thereby reducing the amount of drilling and thus reducing the damage to the structure of the wall 1. The steel plate 21 can directly cooperate with the reinforcement structure 4 and fix the sleeve 2 under the filling effect of concrete 43. The size of the hole 12 should meet the requirements of design and construction. Too large or too small may affect the performance of the structure. The shape of the hole 12 should be as regular as possible to avoid complex geometric shapes, so as to facilitate construction and ensure the stability of the structure.

[0035] In this embodiment, the steel plate 21 on one side is pre-welded to the through-wall tube 22, and the steel plate 21 on the other side is welded to the through-wall tube 22 after the opening 12 is filled with concrete 43, that is, preferably two steel plates 21, the through-wall tube 22 is first fixed on one of the steel plates 21, and then the steel plate 21 is installed on the opening 12, and then the other steel plate 21 is installed on the through-wall tube 22 but not welded and fixed first, and then concrete 43 is filled, and after filling, this steel plate 21 is welded and fixed to the through-wall tube 22. The whole process is simple to operate and easy to use. The through-wall tubes 22 are preferably arranged in two rows and two columns on the steel plate 21, and the specific number can be replaced according to actual conditions.

[0036] In this embodiment, the anchor hole 11 and the transverse reinforcement rib 41 are bonded by anchor glue 44, so that the structure between the transverse reinforcement rib 41 and the wall 1 is more stable. In combination with the longitudinal reinforcement rib 42, the connection at the edge of the opening 12 is more firm and reliable and will not easily shift, thereby avoiding cracks or falling off during construction or use, thereby ensuring the stability of the structure.

[0037] In this embodiment, the anchor hole 11 is arranged on the outside of the hole 12, that is, the anchor hole 11 is at a certain distance from the edge of the hole 12, so that the transverse reinforcement rib 41 can be better welded and fixed with the longitudinal reinforcement rib 42, thereby ensuring the overall strength of the reinforcement structure 4.

[0038] Of course, the longitudinal reinforcing ribs 42 are arranged on the outer side of the steel plate 21, that is, a gap is left between the longitudinal reinforcing ribs 42 and the steel plate 21, and the gap is filled with concrete 43 to make the two more stable and firm.

[0039] In addition, the steel plate 21 is provided with a plurality of air holes 23. The steel plate 21 is preferably rectangular, and the number of the air holes 23 is preferably four, which are respectively provided at the four corners of the steel plate 21. The function of the air holes 23 is to allow air and excess cement slurry to be discharged during the pouring of the concrete 43, thereby reducing internal bubbles and pores and improving the density and strength of the concrete 43. The air holes 23 are usually provided on the surface of the steel plate 21, and the size and distribution thereof should be determined according to the size of the casing 2 and the pouring speed. The design of the air holes 23 can ensure effective exhaust during the pouring of the concrete 43, and at the same time maintain the integrity and durability of the structure after the concrete 43 hardens.

[0040] Embodiment 2

[0041] like Figure 6 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0042] The wall-penetrating pipe 22 may also preferably be in only one row, which may be only one or multiple arranged in sequence. The specific number may be selected according to actual use requirements. The steel plate 21 on such a sleeve 2 has a smaller area, and the hole 12 required to be excavated is also smaller, which will not cause damage to the wall 1 structure.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
