Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of arch type pool anti-floating structure, belong to pool anti-floating technical field. BACKGROUND

[0002] When building pool in underground or high water level area, pool structure faces significant buoyancy pressure in initial stage that has not been put into operation and has not been filled with water inside. If this buoyancy pressure cannot be effectively controlled and managed, it may lead to the floating of pool structure, and even cause structural damage, thereby bringing serious safety hazards. Therefore, anti-floating technology becomes the key technical means to ensure that pool structure remains stable during construction and operation.

[0003] Currently, for pool anti-floating problem, two traditional methods of counterweight method and anchor rod fixing method are mainly used to achieve anti-floating effect. Counterweight method adds additional weight in pool structure to offset the buoyancy exerted by water. The principle of this method is relatively simple, and it is also relatively convenient to implement, so it has been widely used in actual engineering. However, counterweight method has the problem of high cost. In order to achieve sufficient anti-floating effect, a large amount of materials such as concrete, steel, etc. are usually needed, which not only increases the construction cost of the project, but also may adversely affect the construction period and transportation. In addition, counterweight method has high requirements for the design and construction of pool structure, and precise calculation and reasonable counterweight arrangement must be carried out to avoid instability of structure due to uneven counterweight or improper design.

[0004] Another commonly used anti-floating method is anchor rod fixing method. This method fixes pool firmly on the ground by driving anchor rod between pool structure and foundation, so as to prevent it from floating due to buoyancy. Anchor rod fixing method has strong tensile capacity and stability, which can ensure the safety of pool structure to a large extent. However, anchor rod fixing method also faces the problem of high cost. The construction of anchor rod needs professional equipment and technology, and the construction process is complex and time-consuming, especially in areas with complex geological conditions or high underground water level, the construction difficulty and cost are further increased. In addition, the long-term durability and maintenance of anchor rod are also important factors to be considered. If the material selection of anchor rod is improper or the construction quality is not high, it may affect its anti-floating effect, and even cause structural safety problems.

[0005] In addition to the above cost and construction difficulty problems, the existing counterweight method and anchor rod fixing method also have other many deficiencies in practical application. First, these methods need detailed planning and design at the initial stage of pool construction, and cannot be supplemented or adjusted after the pool is built. This means that once the pool construction is completed, if additional anti-floating measures are needed, there will be greater technical and economic challenges. Second, once the counterweight and anchor rod materials are installed, they are usually not reusable, leading to waste of resources and increased environmental burden. In addition, these methods usually require construction in the foundation pit, which is complex and has high technical requirements, increasing the difficulty and risk of the project. Finally, if errors occur in the early design stage, it is difficult to effectively remedy them later, which may result in the failure of the anti-floating measures and threaten the safety of the entire pool structure.

[0006] In summary, although the existing pool anti-floating methods can effectively prevent the pool from floating to some extent, their high cost, complex construction, non-reusable materials, need for early planning, and difficulty in remedying design errors limit their widespread application and promotion. In view of this, there is an urgent need to develop a new type of pool anti-floating method that is lower in cost, simpler in construction, and more adaptable. This new method should be able to ensure anti-floating effect while reducing material and construction costs, improving construction efficiency, and having good flexibility to be suitable for different types and sizes of pool structures. In addition, the new method should also consider the reusability and environmental friendliness of materials to ensure its sustainability and economy in practical application. Therefore, in view of the shortcomings of existing anti-floating technology, it is of great practical significance and broad application prospect to research and develop an innovative, economical and efficient pool anti-floating method that is easy to implement.

[0022] Embodiment 1: Reference Figures 1-4 The embodiment introduces a specific embodiment of the arch type pool anti-floating structure applied to the power plant pool. In a certain large-scale thermal power plant project, a pool with a capacity of 5000 cubic meters needs to be built. Since the underground water level of the power plant is high, the pool faces significant buoyancy pressure in the initial stage without water injection, so the anti-floating structure of the utility model needs to be used to ensure the stability and safety of the pool. The utility model is implemented mainly including the following parts:

[0023] 1) The setting of the support rod, the upper surface of the side wall around the opening of the cooling pool is uniformly arranged with 4 support rods 4, and the initial length of each support rod is 15 meters. The support rod 4 is a telescopic rod with adjustable length, including a rod body 4-2 and a hydraulic telescopic cylinder 4-1. The rod body 4-2 is made of high-strength steel material to ensure that it has sufficient carrying capacity. The hydraulic telescopic cylinder 4-1 is installed at the lower end of the rod body 4-2, which is convenient for adjusting the length of the support rod and thus adjusting the prestress of the steel cable according to the actual situation.

[0024] 2) Connection of anchor rod and steel cable, each support rod 4 corresponds to 2 anchor rods 2 and 1 steel cable. Taking one of the support rods as an example, the steel cable is fixedly connected to the ground through the corresponding anchor rod 2 at both ends. The steel cable passes through the perforation 4-2-1 at the upper end of the support rod 4 and is connected perpendicularly to the central axis of the support rod. The steel cable forms an inverted V-shaped structure at the middle part in contact with the support rod, ensuring that the steel cable is tight and exerts prestress.

[0025] 3) Construction of anchor rod, the anchor rod 2 is made of prestressed steel material with a length of 20 meters. The depth of the anchor rod is determined according to the geological survey results. During construction, professional anchor rod driving equipment is used to vertically drive the anchor rod into the foundation, and it is fixed by pouring cement slurry to ensure the firm connection between the anchor rod and the foundation.

[0026] 4) Tensioning of steel cable, after installation, the length of the support rod 4 is controlled by adjusting the hydraulic telescopic cylinder 4-1 to control the prestress effect of the steel cable. The application of prestress makes the steel cable present an inverted V shape, which can effectively offset the buoyancy of the cooling pool structure.

[0027] The parts not described in the utility model are the known technology of the technical personnel in the technical field. Finally, it is pointed out that the above embodiments are only used to illustrate the technical scheme of the utility model and not to limit it.
