Description

Technical Field

[0001] This utility model relates to the field of structural waterproofing engineering technology, and in particular to a waterproof structure for a wiring substation. Background Technology

[0002] Currently, waterproofing in underground structural engineering remains a major challenge in infrastructure projects. Groundwater has a significant impact on the durability and functionality of structures, especially deep underground stations, which are more susceptible to leakage risks due to pressurized water. Furthermore, under external forces, structures inevitably develop unpredictable cracks, and the difficulty in controlling construction quality often leads to numerous leaks. For substations, the uneven load distribution, higher train vibration frequency and amplitude, and more pronounced structural fatigue effects, coupled with stringent differential settlement limits (typically ≤5mm), mean that existing waterproofing methods cannot achieve satisfactory results. This results in substantial and costly waterproofing and leak-stopping work, with repairs often proving ineffective and unreliable in the long term, posing ongoing risks to the structural safety and operational reliability of substations. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing waterproof structure of the wiring station, which is not ideal and often results in leakage, and to provide a waterproof structure for the wiring station.

[0004] This utility model provides a waterproof structure for a wiring station, including a full-section induced joint along the cross-section of the station. The longitudinal section area of ​​the station with columns is the first cross-section area, the longitudinal section area within a predetermined width range on both sides of the columns is the second cross-section area, and the remaining longitudinal section areas of the station are the third cross-section area. The first top plate longitudinal reinforcement, the first middle plate longitudinal reinforcement, and the first bottom plate longitudinal reinforcement of the first cross-section area are all continuously arranged at the induced joint. The second top plate longitudinal reinforcement and the second bottom plate longitudinal reinforcement of the second cross-section area are continuously arranged at the induced joint. 3 / 5 to 2 / 3 of the second middle plate longitudinal reinforcement of the second cross-section area are disconnected at the induced joint. The third bottom plate longitudinal reinforcement of the third cross-section area is continuously arranged at the induced joint. 3 / 5 to 2 / 3 of the third top plate longitudinal reinforcement and 3 / 5 to 2 / 3 of the third middle plate longitudinal reinforcement of the third cross-section area are disconnected at the induced joint.

[0005] The induced joint is set across the entire cross section, meaning that the station's top slab, inner lining wall, middle slab, and bottom slab all form a concrete interface at this point.

[0006] The waterproof structure of the distribution station described in this utility model, by adjusting the reinforcing steel at the induced joint, can ensure the load-bearing performance and waterproofing capacity of the distribution station's base slab, prevent vertical settlement differences, and effectively form a weak interface at the induced joint. This better confines cracks caused by temperature, settlement, etc., within the induced joint, avoiding unpredictable cracks in the structural body, reducing the risk of water seepage, and effectively releasing water pressure behind it. In addition, drainage through the induced joint better prevents the disorderly diffusion of water in the concrete, effectively improving leakage and reducing the cost of later sealing and repair.

[0007] Preferably, the preset width range w is 1m-1.5m, and additional reinforcing bars are provided between the top plates on both sides of the longitudinal direction of the induced joint in the second cross-section area.

[0008] Preferably, the additional reinforcing bars include upper additional reinforcing bars and lower additional reinforcing bars, and the diameter and spacing of the additional reinforcing bars are the same as the diameter and spacing of the longitudinal reinforcing bars of the second top slab.

[0009] Preferably, the additional reinforcing bars extend along both sides of the longitudinal direction of the induced joint. l Greater than or equal to 3m.

[0010] Preferably, the two adjacent longitudinal bars of the second middle plate, the two adjacent longitudinal bars of the third top plate, and the two adjacent longitudinal bars of the third middle plate are all connected by flexible sleeves, and both ends of the flexible sleeves are closed.

[0011] Preferably, the flexible sleeve is a plastic component, and both ends of the flexible sleeve are thermoplastic sealed.

[0012] Preferably, the guiding joint is located at 1 / 4 to 1 / 3 of the span of the station. Preferably, the induced joint is provided with an embedded waterstop. Preferably, a water collection box is provided below the induction joint located at the top plate, and the water collection box is connected to a drainage ditch.

[0013] External drainage is used to avoid embedding drainage pipes in the concrete, further reducing the risk of leakage.

[0014] Preferably, the water-facing surfaces of the inner lining wall and the bottom plate both have externally applied waterstops at the induced joint, and the water-facing surface of the top plate is provided with sealant at the induced joint, with a plastic film also provided on the outside of the sealant.

[0015] A conventional waterproofing structure can also be installed on the outside of the plastic film (the side away from the top plate).

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a waterproof structure for a distribution station. By adjusting the reinforcing steel at the induced joint, the structural performance and waterproofing capability of the distribution station's base slab can be guaranteed. At the same time, a weak interface can be effectively formed at the induced joint, thereby better confining cracks caused by temperature, settlement, etc., within the induced joint. This avoids unpredictable cracks in the structural body, reduces the risk of water seepage, and effectively releases the water pressure behind it. In addition, drainage through the induced joint better prevents water from spreading disorderly within the concrete, effectively improving leakage and reducing the cost of later sealing and repair.

[0025] Example 1 like Figures 1 to 7 As shown, a waterproof structure for a distribution station includes a full-section induced joint 1 along the cross-section of the station. The longitudinal section area where the station has columns 2 is the first cross-section area, the longitudinal section area within a predetermined width range on both sides of the columns 2 is the second cross-section area, and the remaining longitudinal section areas of the station are the third cross-section areas. The first top plate longitudinal reinforcement 31, the first middle plate longitudinal reinforcement 41, and the first bottom plate longitudinal reinforcement 51 in the first cross-section area are all continuously arranged at the induced joint 1. The second top plate longitudinal reinforcement 32 and the second bottom plate longitudinal reinforcement 52 in the second cross-section area are continuously arranged at the induced joint 1. 3 / 5 to 2 / 3 of the second middle plate longitudinal reinforcement 42 in the second cross-section area are disconnected at the induced joint 1.

Specifically, such as Figure 1 The diagram shows the cross-section of the distribution station where induced joint 1 is located. Induced joint 1 has a centrally embedded waterstop 81 along its entire cross-section, which can be installed at 1 / 4-1 / 3 of the span of the distribution station. The specific location must avoid the electrical room layout and be determined based on the actual situation. For ease of illustration, the reinforcement in this cross-section is only shown for a localized area, not for all locations shown. The longitudinal section area with column 2 is the first cross-section area; see [link to relevant documentation]. Figure 2 As shown, all the longitudinal reinforcement bars 31 of the first top slab, 41 of the first middle slab, and 51 of the first bottom slab are arranged continuously at the induced joint 1. The longitudinal section area with a preset width range w on both sides of the column 2 is the second section area, where w is 1m-1.5m.

Additional reinforcement bars 6 are also provided between the top slabs on both longitudinal sides. The additional reinforcement bars 6 include upper and lower additional reinforcement bars, and their extension lengths towards both longitudinal sides of the induced joint 1 are... l Greater than or equal to 3m. 3 / 5 to 2 / 3 of the longitudinal reinforcing bars 42 in the second intermediate slab are interrupted at the induced joint 1, meaning partially continuous and partially interrupted. The interrupted sections are connected by flexible sleeves 7, both ends of which are closed. The flexible sleeve 7 can be a plastic component or other components that reduce friction, or it can be a corrugated pipe forming a sleeve with the reinforcing bar. If a plastic pipe is used, both ends can be thermoplastic sealed. The length of the pipe is set according to actual needs. Figure 4As shown, the longitudinal reinforcement 53 of the third bottom slab in the third cross-section area is continuously arranged at the induced joint 1. 3 / 5-2 / 3 of the longitudinal reinforcement 33 of the third top slab and 3 / 5-2 / 3 of the longitudinal reinforcement 43 of the third middle slab are also partially continuous and partially discontinuous at the induced joint 1. The reinforcement at the transition between the top slab and the inner lining wall also adopts a partially continuous and partially discontinuous arrangement at the induced joint 1 to prevent stress concentration at this location. The bottom slab is also provided with tenons, such as... Figures 2-4 As shown, the bottom slab is reinforced with continuous steel bars to prevent vertical settlement.

[0026] like Figure 5 As shown, a water collection box 9 is installed below the guide joint 1 at the top slab, and the water collection box 9 is connected to the drainage ditch. The water collection box 9 can be made of stainless steel and is connected to the drainage ditch through a downpipe. The water collection box 9 has a certain slope, such as... Figure 8 As shown, the longitudinal beam above column 2 has pre-drilled holes during construction to facilitate the continuous arrangement of water collection boxes 9. The cross-sectional shape of the water collection box 9 can be selected according to actual needs, such as trough, U-shaped, or semi-circular, and can be connected to the top plate by expansion bolts. Drip lines can be installed on both sides of the induced joint 1. The water-facing surface of the top plate is provided with sealant 83 at the induced joint 1. The sealant 83 can be made of low-modulus polyurethane material. A plastic film 84 is also provided on the outside of the sealant 83. The width of the plastic film 84 is set according to actual needs. A waterproof layer is provided behind the plastic film 84. The waterproof layer can include a first waterproof coating layer, a first isolation layer, a second waterproof coating layer, and a second isolation layer arranged sequentially from the inside out. The first waterproof coating layer is closer to the top plate, and the thickness of the second waterproof coating layer is greater than that of the first waterproof coating layer. The first isolation layer can be polyester fabric, and the second isolation layer can be non-woven fabric.

[0027] The water-facing surface of the inner lining wall has an externally applied waterstop 82 at the induced joint 1, such as... Figure 6 As shown, the water-facing surface of the base plate has an externally attached waterstop 82 at the induced joint 1, such as... Figure 7 As shown.

[0028] The waterproof structure of the distribution station described in this utility model, by adjusting the reinforcing steel at the induced joint 1, can ensure the load-bearing performance and waterproofing capacity of the distribution station's base slab, prevent vertical settlement differences, and effectively form a weak interface at the induced joint 1. This better confines cracks caused by temperature, settlement, etc., within the induced joint, avoiding unpredictable cracks in the structural body, reducing the risk of water seepage, and effectively releasing water pressure behind it. In addition, drainage through the induced joint better prevents water from spreading disorderly within the concrete, effectively improving leakage and reducing the cost of later sealing and repair.

[0029] The above content is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
