[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-5 The utility model provides a technical solution: a device for treating water leakage of a steel casing box in an underwater foundation, comprising a foundation 1, a bottom cover 2 located at the bottom of the foundation 1, a leveling layer 3 arranged on the foundation 1, a steel strand 4 for tensioning is arranged on the leveling layer 3, anchor pads 5 are arranged around the foundation 1, a working anchor 6 is arranged on the anchor pad 5, a jack 7 is arranged on the working anchor 6, a tool anchor 8 is arranged on the upper end of the jack 7, both ends of the steel strand 4 pass through the anchor pad 5, the working anchor 6, the jack 7 and the tool anchor 8 in sequence, a drainage ditch 9 is arranged around the leveling layer 3, a sump 10 is arranged diagonally on the leveling layer 3, the cross-sections of the drainage ditch 9 and the sump 10 are both rectangular, a waterproof membrane 11 is arranged between the foundation 1 and the bottom cover 2, and the waterproof membrane 11 is connected to the foundation 1 and the bottom cover 2 by hot-melt welding.
[0026] Specifically, the sump 10 is provided with a pump 12, and a water level sensor 13 is also provided inside the sump 10. By providing the pump 12 and the water level sensor 13, when the water level sensor 13 detects that the water level in the drainage ditch 9 and the sump 10 reaches a preset threshold, the pump 12 will be automatically started to drain the water. This intelligent design not only improves the efficiency of leakage water treatment, but also reduces the frequency of manual inspections, providing a strong guarantee for construction quality and progress. Ensure that the internal environment of the steel casing of the foundation 1 is always kept dry.
[0027] Specifically, a tool anchor washer 14 is further provided at the bottom of the tool anchor 8. By providing the tool anchor washer 14, the tool anchor 8 can be more stable during installation to prevent loosening due to uneven force or vibration, thereby further enhancing the stability and reliability of the entire tensioning system.
[0028] Specifically, working anchor clips 15 are provided on both sides of the working anchor 6 to ensure that the fastening connection between the working anchor 6 and the steel strand 4 will not fail due to wear or looseness during a long-term, high-intensity tensioning process.
[0029] Specifically, the specification of the drainage ditch 9 is 40*20 cm.
[0030] Specifically, the size of the sump 10 is 40*40*50 cm.
[0031] Specifically, the steel plate 16 is covered on the upper part of the drainage ditch 9 and the sump 10. By covering the steel plate 16 on the upper part of the drainage ditch 9 and the sump 10, the structural strength of the drainage ditch 9 and the sump 10 is increased, ensuring their stability and durability during the construction process. In addition, the smooth surface of the steel plate 16 can also reduce water flow resistance, improve drainage efficiency, so that the leaking water can be quickly collected and discharged, further ensuring the dry environment inside the steel casing of the foundation 1.
[0032] Specifically, the steel strand 4 is a 5-φs15.2 steel strand.
[0033] A specific application example of this embodiment is:
[0034] Prepare the construction of the platform 1, ensure that the bottom cover 2 of the platform 1 has been firmly laid, and the waterproof membrane 11 has been tightly fitted between the platform 1 and the bottom cover 2 through hot-melt welding technology, install the anchor plate 5 around the platform 1, ensure that the position is accurate and fixed firmly. Install the working anchor 6 on the anchor plate 5, and install the working anchor clip 15 to enhance the stability and safety of the anchor. Then, place the jack 7 on the working anchor 6, and install the tool anchor 8 and the tool anchor washer 14 at the bottom to complete the assembly of the tensioning system.
[0035] On the leveling layer 3, the steel strand 4 is arranged according to the design requirements, and the two ends are ensured to pass through the anchor pad 5, the working anchor 6, the jack 7 and the tool anchor 8 to form a complete tensioning system. The steel strand 4 is selected: 50% of the theoretical tensioning force of the steel strand 4 is used as the upper limit of the actual force control, and the number of strands 4 in each bundle is determined according to the concrete strength. The cutting length of the steel strand 4 is the sum of the horizontal or longitudinal length of the steel cofferdam and the length of the tensioning end of the steel strand. The length of the tensioning end is determined according to the anchor pad 5, the working anchor 6, the jack 7 and the tool anchor 8.
[0036] In order to deal with possible water leakage, drainage ditches 9 are carefully designed around the leveling layer 3, and sump pits 10 are set at diagonal positions. The cross-sections of the drainage ditch 9 and the sump pit 10 are both rectangular, which facilitates the smooth collection and discharge of water. Among them, the specifications of the drainage ditch 9 are set to 40*20cm, which not only ensures sufficient drainage capacity, but also avoids excessive encroachment on the structure of the platform 1. The specifications of the sump pit 10 are set to 40*40*50cm, ensuring that a certain amount of accumulated water can be accommodated and quickly discharged through the pump 12 when necessary.
[0037] In order to monitor the water level in the drainage ditch 9 and the sump 10 in real time, a water level sensor 13 is also provided. Once the water level exceeds the preset threshold, an alarm will be automatically triggered and the pump 12 will be started to drain the water, ensuring the dryness and safety of the internal environment of the platform 1.
