Description

Technical Field

[0001] The utility model relates to the technical field of rail transit engineering, and particularly relates to a construction joint waterproof node structure for separate pit construction. Background Technique

[0002] For the main body of an urban rail transit underground station and its affiliated entrances and ventilation shafts, they are constructed in phases. An inevitable construction joint is formed at the interface between the two. The usual practice is to pre-bury grouting pipes and set water-swelling waterstop strips at the construction joint during the construction of the affiliated structure. However, the phenomenon of water leakage is still serious. Generally, repeated grouting is often carried out to stop the leakage. The rectification time is long, the effect is not good, and it is easy to recur. This kind of situation also exists in the waterproof treatment at the combined part during the separate pit construction of municipal engineering. Content of the Utility Model

[0003] The purpose of the utility model is to provide a construction joint waterproof node structure for separate pit construction, which has reasonable structural design, good waterproof effect, avoids repeated grouting in the later stage, ensures construction quality, reduces project cost, and reduces the construction period.

[0004] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0005] A construction joint waterproof node structure for separate pit construction, including a main structure and an affiliated structure. The main structure pre-buries a T-shaped steel plate, and a steel plate is set after the affiliated structure is completed. The T-shaped steel plate is welded to the steel plate, and a water-swelling rubber waterstop strip is set at the weld.

[0006] Furthermore, a stainless steel water receiving box is set on the lower side of the weld, and the leaked water is led to a drainage ditch.

[0007] Compared with the prior art, the utility model has the following advantages:

[0008] The construction joint waterproof node structure for separate pit construction of the utility model has reasonable structural design, good waterproof effect, avoids repeated grouting in the later stage, ensures construction quality, reduces project cost, and reduces the construction period of separate pit construction.

[0014] The following will further describe the embodiments of the present invention in detail with reference to the accompanying drawings.

[0015] As Figure 4 shown, the waterproof structure of the present invention includes the T-shaped steel plate 2 embedded in the main structure 1 and the steel plate 4 after the construction of the accessory structure 3, and the T-shaped steel plate 2 is welded to the steel plate 4. The main structure 1 of the present invention includes the top plate, bottom plate and side wall of the station main body. Correspondingly, the accessory structure 3 includes the top plate, bottom plate and side wall of the accessory facilities.

[0016] Embodiment 1

[0017] As Figure 1 shown, the side wall top of the station main structure 1 is welded to the channel top plate of the accessory structure 3. The T-shaped steel plate 2 is embedded at the side wall top. The T-shaped steel plate 2 includes a vertical steel plate one and a steel plate two. The steel plate one extends into the top plate, and the surface of the steel plate two is exposed on the top plate. After the construction of the channel top plate, a steel plate 4 is provided to be welded to the steel plate two of the T-shaped steel plate 2; a water-swelling rubber water stop strip 5 is provided at the weld, and a stainless steel water receiving box 6 is provided below the weld, and the seepage water is led to the drainage ditch at the bottom plate.

[0018] Preferably, the thickness of the T-shaped steel plate 2 or the steel plate 4 is 4 mm; the steel plate one of the T-shaped steel plate 2 or the tail of the steel plate 4 is bent, which enhances the supporting force and stress of penetrating into the wall of the main structure or the accessory structure. The length of the bent part is 50 mm, and the length of the unbent part is 150 mm; the two ends of the steel plate two of the T-shaped steel plate 2 are bent inward, which enhances the welding firmness between the T-shaped steel plate 2 and the steel plate 4. The length of the bent part is 50 mm, and the length of the unbent part is 300 mm.

[0019] Embodiment 2

[0020] As Figure 2 shown, the side wall of the station main structure 1 is welded to the channel side wall of the accessory structure 3. The T-shaped steel plate 2 is embedded in the station side wall. The T-shaped steel plate 2 includes a vertical steel plate one and a steel plate two. The steel plate one extends into the side wall, and the surface of the steel plate two is exposed on the side wall. After the construction of the channel side wall, a steel plate 4 is provided to be welded to the steel plate two of the T-shaped steel plate 2; a water-swelling rubber water stop strip 5 is provided at the weld, and a stainless steel water receiving box 6 is provided below the weld, and the seepage water is led to the drainage ditch at the bottom plate.

[0021] The shapes and dimensions of the T-shaped steel plate 2 and the steel plate 4 are the same as those in Embodiment 1.

[0022] Embodiment 3

[0023] As Figure 3 shown, the bottom plate of the main structure 1 of the station is welded to the bottom plate of the passage of the auxiliary structure 3. A T-shaped steel plate 2 is embedded in the bottom plate of the side wall of the station. The T-shaped steel plate 2 includes a vertical steel plate 1 and a steel plate 2. The steel plate 1 extends into the bottom plate, and the surface of the steel plate 2 is exposed on the bottom plate. After the construction of the bottom plate of the passage, a steel plate 4 is provided to be welded to the steel plate 2 of the T-shaped steel plate 2; a water-swellable rubber water stop strip 5 is provided at the weld, and a stainless steel water collecting box 6 is provided on the lower side of the weld to lead the seepage water to the drainage ditch of the bottom plate.
