[0002] With the development of underground space accelerating, prefabricated shafts have been widely used in urban infrastructure construction due to their advantages such as fast construction speed, easy quality control and low environmental impact. Shafts can be used for underground transportation, ventilation, drainage, underground garages and many other purposes. However, due to the complexity of the underground environment, especially the problem of groundwater infiltration, the waterproof function of prefabricated shafts has become a key technical issue in design and construction.

[0003] The long-term stability and safety of underground projects largely rely on the waterproof function of prefabricated shafts. Water penetration may not only lead to corrosion and deterioration of structural materials, but also cause softening of the surrounding soil, thus affecting the stability of the shaft. Secondly, the joints of prefabricated shafts are potential sources of leakage. Traditional shaft structures that only use concrete segments and bottom concrete have joints between the segments, providing a possible path for surrounding water to penetrate.

[0004] Therefore, how to improve the waterproof performance of the assembled shaft becomes a technical problem that needs to be solved in this field. Utility Model Content

[0022] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with the implementation modes.

[0023] Prefabricated shafts are widely used in underground parking garages, municipal engineering shafts, subway construction, underground space development and other fields due to their advantages of fast construction speed, controllable quality, high safety, low cost and low environmental impact. At present, prefabricated shafts generally use a combination of pipe segments and concrete structures to prevent water seepage. The concrete structure can better prevent water from the bottom of the shaft from penetrating upward, but the sides of the shaft are composed of pipe segments. Water seepage usually seeps in from the gaps between the pipe segments, affecting the stability and bearing capacity of the shaft. Water seepage will also accelerate the corrosion of the reinforced concrete pipe segment structure and affect the durability of the shaft.

[0024] like Figure 1 As shown, according to the first aspect of the present application, a waterproof device for an assembled vertical shaft is proposed, and the waterproof device for the assembled vertical shaft comprises: a pipe segment 1, which is arranged on the side of the assembled vertical shaft and extends along the axial direction of the waterproof device for the assembled vertical shaft; a concrete structure 2, which is arranged on the bottom surface of the assembled vertical shaft and is perpendicular to the pipe segment 1; wherein the waterproof device for the assembled vertical shaft also includes an outer waterproof structure, and the outer waterproof structure is arranged on the outer side surface of the pipe segment 1 in the axial direction.

[0025] In the structure of the assembled vertical shaft, the pipe segments 1 are prefabricated structures. During construction, they only need to be installed on site. Although the shaft of the vertical shaft composed of the pipe segments 1 can provide stable support for the vertical shaft, the gaps between the pipe segments 1 will inevitably have water seepage, affecting the structure of the pipe segments 1. Therefore, the waterproof device for the assembled vertical shaft proposed in this application is provided with an outer waterproof structure on the outside of the pipe segments 1, which can effectively prevent water from entering the interior of the vertical shaft through the gaps between the pipe segments 1, and can also effectively prevent water from contacting the pipe segments 1, thereby avoiding corrosion of the reinforced concrete structure of the pipe segments 1 and affecting the durability and stability of the vertical shaft.

[0026] like Figure 1 and Figure 2 As shown, in order to ensure the waterproof effect of the assembled shaft, specifically, the outer waterproof structure may include a waterproof member 3 and a waterproof material 4. The waterproof member 3 can prevent the pipe segment 1 from being eroded by water and causing structural damage, and the waterproof material 4 can further prevent the pipe segment 1 from contacting with water, thereby avoiding the structural damage of the pipe segment 1 and extending the service life of the assembled shaft.

[0027] In order to ensure the continuity of waterproofing, specifically, the waterproofing member 3 can be fixedly connected to the pipe segment 1. The joints between the pipe segments 1 are the weak link of the waterproofing of the shaft structure. The fixed connection of the waterproofing member 3 can ensure that the waterproof layer is continuous and tight, which can effectively prevent water penetration and protect the structure from erosion by groundwater and the external environment; secondly, the water pressure, soil pressure and the weight of the structure itself may exert force on the pipe segment 1. The fixed connection of the waterproofing member 3 to the pipe segment 1 can increase the stability of the overall structure and prevent the displacement or falling off of the waterproofing member 3. The above-mentioned waterproofing member 3 can be in an appropriate form, such as an outer water retaining strip, a waterproof sealing gasket, preferably a steel ring, the steel ring can be a flexible steel ring, preferably a rigid steel ring, the steel ring and the pipe segment 1 can be fixedly connected in an appropriate manner, such as using an adhesive, and the adhesive can be an epoxy adhesive; the fixed connection between the steel ring and the pipe segment 1 can be achieved by welding the pre-buried anchor bolts in the pipe segment 1 to the steel plate. The joints between the steel rings can be fixedly connected, such as welding or bolting.

[0028] In order to further ensure the waterproof effect, specifically, the waterproof material 4 can be a continuous waterproof material 4, which is arranged on the outside of the waterproof part 3. The above-mentioned waterproof material 4 can be in an appropriate form to achieve the effect of continuous waterproofing, for example, it can be a waterproof coating, a waterproof membrane, a self-adhesive waterproof material, spray polyurea, preferably a waterproof cement mortar, which can provide a waterproof function while also providing support for the shaft structure, and can form a continuous seamless waterproof layer on the outside of the waterproof part 3, avoiding the problem of water leakage at the joints, and has strong adaptability, can provide comprehensive waterproof protection for the shaft structure, and is easy to construct and has good durability. The continuous waterproof material 4 is used to form a continuous waterproof layer on the outside of the shaft, which improves the integrity of the waterproof layer. After the construction of the waterproof part 3 is completed, the waterproof cement mortar can be poured into the gap between the waterproof part 3 and the soil by setting a grouting pipe on the ground.

[0029] like Figure 1 and Figure 2 As shown, in order to install the waterproof part 3 and the continuous waterproof material 4, specifically, the outer side of the prefabricated shaft is provided with an over-excavation area 5 according to the construction process, and the outer waterproof structure can be arranged in the over-excavation area 5. In actual construction, the outer waterproof structure is consistent with the width of the over-excavation area 5, and is in seamless contact with the pipe segment 1 and the soil around the prefabricated shaft, which can better ensure the stability of the overall structure of the shaft.

[0030] like Figure 1 and Figure 3As shown, in order to fix the pipe segment 1, specifically, the contact portion between the pipe segment 1 and the concrete structure 2 can be provided with a blade foot 6, the inner side of the blade foot 6 is embedded in the concrete structure 2, and is used to fix the pipe segment 1. The blade foot 6 and the pipe segment 1 can be connected in an appropriate manner, such as a bolt connection or a positioning pin connection. During construction, the blade foot 6 can smoothly penetrate the soil layer. The special shape of the blade foot 6 helps to reduce the resistance during the settlement of the shaft, and can also be applied to different geological conditions; the blade foot 6 sinks together with the concrete structure 2 to ensure the stability of the upper structure. The inner side and bottom surface of the blade foot 6 are fixed by the concrete structure 2, and can form a vertical closed waterproof system with the concrete structure 2.

[0031] In order to ensure the sealing of the bottom of the assembled shaft, specifically, a bottom plate 7 may be provided at the bottom of the assembled shaft, and the bottom plate 7 is provided above the concrete structure 2. The bottom plate 7 provided above the concrete structure 2 can provide an additional sealing layer for the bottom of the assembled shaft, ensure the waterproof performance of the shaft, and prevent groundwater from entering the shaft; the bottom plate 7 can also increase the bearing capacity of the shaft structure and can withstand greater loads; the bottom plate 7 also helps to improve the stability of the entire shaft structure, especially in areas with unstable soil or high groundwater levels; installing the bottom plate 7 also makes the internal surface of the shaft flat, which is convenient for subsequent construction or installation work. The above-mentioned bottom plate 7 can be a prefabricated or on-site constructed reinforced concrete structure.

[0032] like Figure 4 As shown, after the construction of the base plate 7 is completed, in order to ensure the safety, stability and durability of the overall structure, the gap between the segment 1 and the concrete structure 2 needs to be closed. This can be done by setting a grouting pipe 8 on the base plate so that the grouting pipe 8 passes through the base plate and contacts the segment 1 and the concrete structure to fill the gap between the segment 1 and the concrete structure.

[0033] The waterproof device for the prefabricated vertical shaft proposed in the present application has a certain waterproof effect on the pipe segments of the prefabricated vertical shaft. By arranging a waterproof structure on the outer side of the pipe segments, an additional waterproof layer and protective layer are provided for the prefabricated vertical shaft, which can effectively prevent moisture penetration, reduce the risk of leakage, and ensure the long-term stability and safety of the vertical shaft.

[0034] According to a second aspect of the present application, a prefabricated vertical shaft is provided, wherein the prefabricated vertical shaft comprises the waterproof device for the prefabricated vertical shaft described above.

[0035] The preferred embodiments of the present application are described in detail above; however, the present application is not limited to the specific details in the above embodiments. Within the technical concept of the present application, a variety of simple modifications can be made to the technical solution of the present application, and these simple modifications all fall within the protection scope of the present application.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not further describe various possible combinations.

[0037] In addition, the various implementation modes of the present application may be arbitrarily combined, and as long as they do not violate the concept of the present application, they should also be regarded as the contents disclosed by the present invention.
