Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste well reconstruction engineering, in particular to a method and structure for reconstructing a deep diving space based on a temporary working well of a tunnel. BACKGROUND

[0002] At present, after the construction of a traditional intercity railway shield tunnel is completed, the disposal method of the temporary working well generally adopts a backfilling and abandoning scheme, which leads to permanent waste of underground space resources with high construction cost in the early stage. In recent years, the construction of indoor deep diving halls mainly relies on two new construction modes: shield machine underground excavation forming or ground pouring of deep water pools, both of which have the following problems:

[0003] Firstly, resource waste, the backfilling of the working well leads to the abandonment of the reinforced concrete structure and deep underground space resources, which conflicts with the intensive development of the city, and the repeated construction of similar deep diving facilities aggravates resource consumption. Secondly, high cost, the construction of new deep diving facilities needs to build super deep structures from zero, and shield excavation or mass concrete pouring makes the cost of a single project high, which is much higher than the cost of existing structure reconstruction. Moreover, the existing diving pools generally adopt single depth design, and the functional areas are not set according to the diving training requirements, which leads to the mixed use of shallow water experience area and deep water competition area, insufficient space utilization, and high constant temperature energy consumption. In addition, there is a lack of reliable isolation design between the newly built deep diving facilities and the adjacent operating tunnel, which may cause leakage under full water load, threatening the safety of the railway structure. The above defects seriously restrict the popularization of deep diving sports and the utilization of urban underground space resources, and an economic, functional and safe solution is urgently needed. SUMMARY

[0027] According to a first aspect of the present application, as shown in Figure 1 , Figure 2 and Figure 4 , an embodiment of the present application provides a method for reconstructing a deep diving space based on a temporary working well of a tunnel, comprising: building a reinforced concrete bottom plate at the bottom of an existing temporary working well of a tunnel, blocking a translation passage between the temporary working well of the tunnel and a main tunnel, and safely isolating the temporary working well of the tunnel; dividing the temporary working well of the tunnel into an underground medium diving area and an underground deep diving area along the depth direction of the temporary working well of the tunnel; building a main structure side wall at the underground medium diving area, and structurally reinforcing the underground medium diving area; building a cylindrical lining at the underground deep diving area, and backfilling and reinforcing outside the cylindrical lining to structurally reinforce the underground deep diving area; brushing cement-based permeable crystalline coating on the outer surfaces of the main structure side wall and the cylindrical lining, and setting a water stop at the junction between the underground medium diving area and the underground deep diving area to waterproof the temporary working well of the tunnel; building a support and a wall on the ground of the temporary working well of the tunnel, and enclosing a shallow water area on the ground by using the support and the wall to expand the temporary working well of the tunnel.

[0028] Specifically, as shown in Figure 1 , an embodiment of the present application further provides a method for reconstructing a deep diving space based on a temporary working well of a tunnel, the method comprising:

[0029] Step 102, laying a reinforced concrete bottom plate at the bottom of the existing tunnel temporary working well, blocking the translation channel between the tunnel temporary working well and the main line tunnel, and safely isolating the tunnel temporary working well;

[0030] Step 104, dividing the tunnel temporary working well into an underground medium submersible area and an underground deep submersible area along the depth direction of the tunnel temporary working well;

[0031] Step 106, laying a main structure side wall in the underground medium submersible area to structurally reinforce the underground medium submersible area;

[0032] Step 108, laying a cylindrical lining in the underground deep submersible area and backfilling and reinforcing outside the cylindrical lining to structurally reinforce the underground deep submersible area;

[0033] Step 110, brushing cement-based permeable crystalline coating on the outer surface of the main structure side wall and the cylindrical lining, and setting a water stop strip at the junction of the underground medium submersible area and the underground deep submersible area to waterproof the tunnel temporary working well;

[0034] Step 112, building a support and a wall on the ground of the tunnel temporary working well, and enclosing an above-ground shallow water area with the support and the wall to expand the tunnel temporary working well.

[0035] Specifically, in step 102, the reinforced concrete bottom plate with a thickness of ≥1.5m is laid to block the translation channel and cut off the physical connection between the tunnel temporary working well and the operating tunnel, eliminate the risk of water leakage into the main line tunnel, and achieve structural safety isolation. In step 104, the well body is divided into an underground medium submersible area and an underground deep submersible area according to the depth to provide a partition basis for subsequent differential reinforcement. In step 106, a main structure side wall with a thickness of ≥0.6m is laid in the underground medium submersible area to enhance the shallow well wall's lateral pressure resistance and prevent water and soil pressure from causing well body deformation. In step 108, a cylindrical lining with an outer diameter of 8.6m and an inner diameter of 7.6m is constructed in the underground deep submersible area using the slip form method, and the cylindrical lining is backfilled with fluidized solidified soil to form a concentric circular bearing structure, improving the stability and impermeability of the deep structure. In step 110, the cement-based permeable crystalline coating forms an outer waterproof layer, combined with the water stop strip at the junction, to form a double barrier of "structural waterproofing + node sealing", reducing the probability of leakage. In step 112, a steel structure support and a retaining wall are built on the ground to quickly build an above-ground shallow water area retaining system and expand the usable water area. The above steps combine layered reinforcement, zoned waterproofing, and ground expansion to convert the abandoned tunnel temporary working well into a safe and reliable multi-level deep submersible space, reducing construction costs and improving space utilization.

[0036] Specifically, after the construction of the traditional intercity railway shield tunnel is completed, the disposal method of the temporary working well generally adopts the backfilling and abandonment scheme, which leads to the permanent waste of the underground space resources with high construction cost in the early stage. In recent years, the construction of indoor deep diving halls mainly relies on two new construction modes: shield machine underground excavation forming or ground pouring deep water pool, both of which have the following problems: first, resource waste, the working well backfilling treatment leads to the waste of the early investment, the simple abandonment of the underground structure with high construction cost, and the resource saving and asset value increase cannot be realized, and the repeated construction of similar spaces also causes significant resource waste. Second, high cost, the newly built deep diving facilities need to build ultra-deep water structure from scratch, involving shield excavation and structure pouring engineering, the overall cost is high, much higher than the cost of the reconstruction of the existing working well structure, this high investment mode not only raises the entry threshold of the deep diving industry, but also limits the popularization and promotion of the deep diving industry in the urban core area. Third, low space efficiency, the existing diving pool generally lacks scientific zoning design, cannot accurately match the depth and function according to the diving demand, and leads to low space use efficiency, high energy consumption and other problems.

[0037] To solve the problems of the prior art, such as Figure 1 、 Figure 2 and Figure 4As shown, the method for reconstructing a deep diving space based on a tunnel temporary working well provided by the present application realizes the upgrading of the abandoned tunnel temporary working well to a multifunctional deep diving space structure through the reconstruction of several major technologies such as structural transformation, functional partitioning, and safety guarantee, and specifically includes: structural reinforcement and isolation, well bottom masonry of a 1.5m thick reinforced concrete bottom plate, and plugging of the original shield translation channel; underground medium diving area with a depth of 7m-24m, relying on well wall masonry of a 0.6m thick reinforced side wall; underground deep diving area with a depth of 24m-66m, adopting a slip-form method to construct a cylindrical lining with an outer diameter of 8.6m and an inner diameter of 7.6m, backfilling the outside with fluidized solidified soil, and brushing cement-based permeable crystalline paint for waterproofing. Vertical functional partitioning, ground steel structure support and acrylic material wall body are built to enclose the above-ground shallow water area, which is arranged from top to bottom, the first stage area with a depth of 1.2m serving as a water playing pool and a novice training area; the second stage area and the third stage area with a depth of 1.2m-7m serving as mermaid and water dance training and competition areas; the underground space is divided into the fourth stage area with a depth of 7m-12m serving as a free diving and scuba diving area, the fifth stage area with a depth of 12m-24m serving as a three-star free diving area, and the sixth stage area with a depth of more than 24m serving as a professional competition area. In addition, the method for reconstructing a deep diving space based on a tunnel temporary working well also sets up a waterproof system, specifically a self-waterproofing deep diving space structure, a cement-based coating, and a water stop strip at the junction of the underground deep diving area, to realize the waterproof function of the deep diving space structure; a constant temperature control system, specifically a source heat pump to maintain constant water temperature; and a safety protection system, including a retractable protective net at a depth of 40m, full-coverage underwater monitoring equipment, and an underwater emergency lifting device. Through the innovative design of "resource utilization of abandoned structures, modularization of functional scenes, and globalization of safety protection", the present application breaks through the cost and space constraints of deep diving facility construction, and provides a standardized path for low-carbon regeneration of urban underground space.

[0038] In specific applications, the method for reconstructing a deep diving space based on a tunnel temporary working well can be specifically a method for reconstructing a deep diving space based on an intercity railway shield tunnel temporary working well or a method for reconstructing a deep diving space based on an existing working well. The purpose of the present application is to utilize the spatial basis of the existing tunnel temporary working well, realize low-cost and high-efficiency super deep diving space construction through innovative reconstruction, and at the same time meet the requirements of structural safety and multifunctional utilization, that is, through the reconstruction of the existing working well structure, the railway operation safety and the expansion of the deep diving function are considered, and finally a new mode of deep diving space construction of "resource activation + cost optimization + functional composition" is formed.

[0039] In some embodiments, optionally, as Figure 1 and Figure 4As shown, the above-ground shallow water area is enclosed by the support and the wall, the ground of the temporary working well of the tunnel is expanded, and specifically, the above-ground shallow water area is divided into a first stage area, a second stage area and a third stage area along the depth direction of the temporary working well of the tunnel, wherein the first stage area is arranged on the upper side of the second stage area and is used as a splashing pool and an entry training site, and the second stage area and the third stage area are arranged on the lower side of the first stage area and are used as mermaid and water dance training sites.

[0040] Specifically, as shown in Figure 4 , the ground expansion area corresponds to the first stage area to the third stage area, a circular pool is newly built above the ground of the temporary working well of the tunnel, a combination of a steel structure support and an acrylic wall is adopted, the first stage area has a depth of 1.2 m and is used as a splashing pool and an entry training site, and the second stage area and the third stage area have a depth of 1.2 m to 7 m and are used for mermaid and water dance training and competition and are equipped with a liftable viewing stand to meet the experience and teaching requirements of the shallow water area.

[0041] Specifically, the first stage area is located on the uppermost side and has a depth of 0 to 1.2 m from the ground and directly bears the functions of splashing and novice training, the second stage area and the third stage area extend downward by 1.2 m to 7 m in depth and are connected through a ladder-shaped platform, the 1.2 m shallow water depth of the first stage area avoids panic of beginners and reduces the teaching risk, the maximum depth of 7 m of the second and third stage areas meets the requirements of the jumping and diving depth of mermaid performance and the space requirement of water dance training, the stage areas are supported by a steel structure support and an acrylic transparent wall to form an open water area without columns, the second and third stage areas share the same plane space and flexibly adjust the area of the training area and the competition area through a detachable partition. The zoning design improves the space utilization rate of the shallow water area and reduces the construction cost of the wall through depth progression and function correlation layout.

[0042] In some embodiments, as shown in Figure 1 and Figure 4 , the temporary working well of the tunnel is divided into an underground medium diving area and an underground deep diving area along the depth direction of the temporary working well of the tunnel, and specifically, the underground medium diving area is divided into a fourth stage area and a fifth stage area along the depth direction of the temporary working well of the tunnel, wherein the fourth stage area is arranged on the lower side of the third stage area and is used as a free diving and scuba diving site, and the fifth stage area is arranged on the lower side of the fourth stage area and is used as a three-star free diving site; the underground deep diving area is used as a sixth stage area and is arranged on the lower side of the fifth stage area and is used as a professional deep diving training site.

[0043] Specifically, as shown in Figure 4As shown, the underground renovation area, corresponding to zones four through six, utilizes the original temporary tunnel working shafts for tiered renovation of the underground space. Zone four has a water depth of 7m-12m, meeting the needs of two-star freediving and scuba diving certifications; zone five has a minimum depth of 12m-24m, targeting three-star freediving certifications; and zone six, with a depth of 24m-66m, forms the "Deep Blue Hole" competition zone, suitable for professional deep-sea diving training. By dividing the temporary tunnel working shafts into underground mid-diving and deep-diving zones, precise depth matching is achieved, improving the efficiency of underground space training and reducing energy consumption.

[0044] In some embodiments, optionally, such as Figure 1 As shown, a cylindrical lining is constructed in the underground deep-sea area, and backfilling and reinforcement are carried out on the outside of the cylindrical lining. The underground deep-sea area of ​​the temporary working shaft of the tunnel is structurally reinforced, specifically including: the cylindrical lining is constructed using the slipform method, and the backfilling and reinforcement are carried out using fluidized solidified soil.

[0045] Specifically, such as Figure 2 As shown, the cylindrical lining constructed using the slipform method provides radial structural resistance and withstands water pressure without deformation; the fluidized solidified soil forms a flexible buffer layer, absorbing ground deformation stress and reducing the lining load. This method, through a combination of efficient forming and adaptive backfilling, shortens the construction cycle of deep structures, reduces costs, and lowers the lining leakage rate. The use of specific processes for constructing cylindrical linings in deep underground areas, combined with backfilling measures, enables the transformation and reconstruction of existing tunnel temporary working shafts into deep-sea spatial structures.

[0046] In some embodiments, optionally, such as Figure 1 and Figure 9 As shown, a framework and walls are erected on the ground of the temporary working shaft in the tunnel to enclose a shallow water area. After expanding the temporary working shaft on the ground, the method for converting it into a deep-sea submersible space also includes: installing a constant temperature control system in the deep-sea submersible space to control the water temperature; installing a water circulation and filtration system in the deep-sea submersible space to purify the water quality; installing a retractable protective net in the underground deep-sea submersible area to protect the water area; installing underwater monitoring equipment in the underground deep-sea submersible area to monitor the water conditions in the deep-sea submersible space in real time; and installing an underwater emergency lifting device in the deep-sea submersible space for emergency rescue in case of accidents.

[0047] Specifically, such as Figure 9 As shown, the constant temperature control system uses a ground source heat pump connected to the heat exchange pipe at the bottom of the well to eliminate temperature stratification in deep water by dynamically adjusting the water temperature; the water circulation filtration system filters the water quality in the deep diving space; the retractable protective net is set at a depth of 40m to achieve physical isolation of the professional training area; underwater monitoring equipment is deployed on the side wall of the sixth stage area to capture abnormal diver postures in real time; the emergency lifting device includes a winch and a pressure-resistant rescue capsule to ensure that personnel at a depth of 66m can be rescued within 30 seconds.

[0055] like Figure 4 and Figure 8 As shown, the underground deep-sea diving area 216 includes a sixth-level area 218, which is located below the fifth-level area 215 and serves as a professional deep-sea diving training ground. Through vertical functional zoning and space optimization design, following the principles of "increasing depth, functional adaptation, and reasonable area reduction," the deep-sea diving space structure 200 is divided into functional areas of different depths. The surface expansion area increases the shallow water area to meet the needs of experience and teaching, while the underground area shrinks its cross-section with depth to optimize structural economy, adapting to the needs of all scenarios from beginner to professional competition.

By arranging the constant temperature control system 270 and the water circulation and filtration system 272, the functional applicability of the deep diving space structure 200 is improved.

[0058] In some embodiments, optionally, as shown in Figure 9 The deep diving space structure 200 further comprises: a retractable protective net 274 arranged in the underground diving area 216, used for protecting the water area of the underground diving area 216; and an underwater monitoring device 276 arranged in the underground diving area 216, used for monitoring the water area in the deep diving space structure 200.

The retractable protective net 274 is arranged in the underground diving area 216, used for protecting the water area of the underground diving area 216; and the underwater monitoring device 276 is arranged in the underground diving area 216, used for monitoring the water area in the deep diving space structure 200. By arranging the retractable protective net 274 and the underwater monitoring device 276, the safety of the deep diving space structure 200 is improved.

[0060] In some embodiments, optionally, as shown in Figure 9 The deep diving space structure 200 further comprises: an underwater emergency lifting device 280 comprising a ground fixed end 282 and a water area movable end 284, used for emergency rescue.

[0061] Specifically, as shown in Figure 9 The deep diving space structure 200 further comprises the underwater emergency lifting device 280. The underwater emergency lifting device 280 comprises the ground fixed end 282 and the water area movable end 284. The ground fixed end 282 is fixed on the ground, and the water area movable end 284 is movably arranged in the water area of the deep diving space structure 200, used for emergency rescue in case of danger.

[0062] In a specific application, the deep diving space structure 200 is reconstructed from the temporary working well of the tunnel, and in terms of structure and waterproofing, adaptive measures are adopted for different areas above and below ground. In the area with water depth of 0-7m above ground, a steel support 262 and wall 264 are used to construct the main body of the shallow water area and good sealing treatment is done. In the area with water depth of 7-24m below ground, the existing temporary working well 210 of the tunnel is relied on, and a 0.6m thick main structure side wall is constructed on the inside through the enclosure structure 230. In the area with water depth of 24-66m below ground, a circular cylindrical lining is constructed by slip-form method, the cylindrical lining has an outer diameter of 8.6m, an inner diameter of 7.6m, and a thickness of 0.5m, the outside is backfilled with fluidized solidified soil, and an additional waterproof layer is added outside the cylindrical lining, and cement-based permeable crystalline coating is applied to the outside of the structure to meet the three waterproof requirements. The bottom plate is made of 1.5m thick reinforced concrete, and a ring beam is used to connect the variable cross-section.

[0063] In terms of safety isolation between sections, the deep diving space structure 200 and the main structure of the section main line tunnel 300 have a horizontal clear distance of about 30m, and the pool bottom plate of the deep diving space structure 200 is located above the top plate elevation of the tunnel main structure. The pool bottom plate is made of 1.5m thick reinforced concrete, and the original shield translation passage between the intercity tunnel is sealed by a 1m thick reinforced concrete wall, and the side wall of the intercity tunnel main structure is 1.2m thick reinforced concrete, both of which adopt 3 waterproof measures. At the same time, the main structure of the intercity tunnel is in the weakly permeable layer of the medium weathered granite, which ensures that the thickness of the rock layer covering layer is greater than 5m. In summary, the design of the main structure of the intercity tunnel has considered the working condition under full water head, and the design of the deep diving space structure 200 has fully considered the characteristics of the water storage pool to avoid leakage, and there is no waterway between the two structures. The possibility of water gushing in the intercity railway tunnel is low, and the waterproof problem is safe and controllable.

[0064] In addition, the waterproof structure 250 uses impermeable concrete to achieve self-waterproofing of the structure, and the outside is coated with cement-based permeable crystalline coating as an outer waterproof layer. Water-swelling water stop 254 is set at the junction of deep and shallow water areas as an additional waterproof measure, and multiple safeguards reduce the risk of leakage.

[0065] In addition, a constant temperature control system 270, i.e. a ground source heat pump system, is configured to maintain the stability of the water temperature in the pool, and a water circulation and filtration system 272 is also provided to periodically complete the water circulation of the whole pool to ensure clean water quality and comfortable diving environment.

[0066] In addition, a retractable protective net 274 is set at a depth of 40m to implement hierarchical management of the super-deep water area, and only personnel with professional qualifications are allowed to enter; a full-coverage underwater monitoring device 276 is deployed, and an underwater emergency lifting device 280 is also provided to ensure real-time monitoring and rapid disposal of emergencies during diving.
