[0002] In production and construction, water supply and drainage are needed, so water pool is needed. Traditional cast-in-place pool is gradually faced with elimination due to long maintenance cycle, low construction efficiency and other shortcomings, and relatively, prefabricated assembly pool is more and more popular and applied due to high construction quality, short construction period, green environmental protection and other advantages.
[0003] The prefabricated assembly pool of prior art generally includes a plurality of prefabricated side plates, each prefabricated side plate is provided with an outwardly protruding transverse connecting reinforcement on both sides, and a wet joint is formed between every two adjacent prefabricated side plates. Workers place each prefabricated side plate on a concrete cushion, set up side formwork on both sides of each wet joint, pour wet joint concrete, and anchor the connecting reinforcements of adjacent two prefabricated side plates, to form a whole side wall structure of the pool after drying. In addition, the concrete bottom plate of the pool needs to be poured on the concrete cushion, and the top cover of the pool is placed on the upper edge of the whole side wall.
[0004] The prefabricated assembly pool still has a series of defects. First, to ensure strength and bearing capacity, especially to support the pool top cover plate, the prefabricated side plate wall thickness needs to be increased, which increases the self-weight of the prefabricated component, leading to difficulty in carrying and lifting, and construction difficulty. In addition, the thickened pool side wall occupies more water storage area and reduces the water storage capacity of the pool. Moreover, the wet joint still needs to be set up inside and outside the side formwork for pouring, which is time-consuming and laborious. In addition, the wet joint is poured after the prefabricated side plate, and the waterproof and anti-seepage effect between the prefabricated side plate is general, which has the risk of water leakage. Furthermore, the joint position between the pool cast-in-place bottom plate and the prefabricated side plate also has the risk of water leakage. In addition, to ensure the firmness of the butt joint of each side plate and the adjacent side plate, a plurality of connecting reinforcements are arranged on the side edge of each side plate from bottom to top, which increases the difficulty of transportation and lifting. UTILITY MODEL CONTENTS

[0007] Compared with the prior art, the UHPC prefabricated assembly type pool with the above structure has the following advantages.
[0008] Firstly, the adjacent prefabricated side plates are butted by the post-cast connecting columns, and the two clamping strip mouths of the adjacent prefabricated side plates are closed to form a wet joint cavity, without the need to support the mold inside and outside the post-cast joint as in the prior art, which simplifies the construction steps of supporting the mold, shortens the construction period, reduces the labor cost, saves the operation space outside the pool, and reduces the excavation workload of the pool foundation pit; moreover, the hardened column just clamps the mouths of the two prefabricated side plates to form a mortise and tenon structure, which provides strong and stable support for each prefabricated side plate, so that it can resist the water pressure of the pool and not fall down, so it is not necessary to fully fill a row of connecting ribs from top to bottom on each side edge of the prefabricated side plate as in the prior art to ensure firm connection, but only a few protruding connecting cross ribs are arranged in the range of the top beam height, so the operation difficulty of the prefabricated component transportation and hoisting butt joint is reduced; moreover, the butt joint of each section of the top beam is realized at the same time as the connecting column is cast, so that it forms a ring beam on the top of the pool, and the butt joint of the connecting column and the ring beam is also completed at the same time, forming an overall beam-column frame structure, thereby providing stable support for the cover plate on the top; due to the strength surplus of the beam-column frame structure formed by the side wall of the present application, the back plate can be made thin, thereby further strengthening the advantages of the UHPC material component, such as good quality, high strength, thin wall thickness, and light weight, so that the light weight leads to convenient transportation and assembly, the thin wall thickness leads to low material consumption cost and large water storage capacity, and cost reduction and efficiency increase are realized; in addition, the waterproof effect of the above-mentioned prefabricated side plates after butt joint is also good, the waterproof and anti-seepage performance of the UHPC material itself is relatively superior, and the winding and tortuous connection between the prefabricated C-shaped clamping mouth and the post-cast connecting column effectively prolongs the water seepage path, further enhancing the anti-seepage effect. Due to the advantages of light and thin and good anti-seepage effect of the pool of the present application, it is especially suitable for harsh environments such as mountain agricultural irrigation water storage pools, mountain industrial breeding pools, mountain highway tunnel and bridge fire-fighting water storage pools.
