Laminar flow pool and construction method thereof

Abstract

The invention relates to a laminar flow pool and a construction method thereof. The laminar flow pool comprises a sand cushion layer, plain concrete cushion layers, a sliding layer, a pool body and a grid box. The method comprises the steps that 1, a construction area is excavated to a designed depth according to a traditional construction mode, a dewatering well is excavated around the pool body, and the sand cushion layer is laid; 2, the lower plain concrete cushion layer, the sliding layer and the upper plain concrete cushion layer are sequentially constructed; 3, steel bar binding and formwork erecting of the pool body and pouring of a concrete body are conducted to form the pool body; 4, steel bar binding and formwork erecting of the grid box and pouring of a concrete body are conducted to form the grid box; 5, the grid box is filled with balance weight filling objects; and 6, trial operation of the pool body is performed, and a body project is finished. According to the characteristic that the operation water level of the top of the laminar flow pool is low, by the adoption of the top water level dead area and the grid box type arrangement mode, the grid box is filled with ordinary soil instead of concrete balance weights, and finally the floating-resistant balanced laminar flow pool arrangement mode is achieved.

Description

technical field [0001] The invention relates to the field of steel rolling cooling facilities, in particular to a laminar flow pool and a construction method thereof. Background technique [0002] Due to the large depth of the existing hot-rolled cold water pool, two methods are generally adopted for anti-floating design: one is to increase the amount of concrete and use a thick bottom plate to increase the overall weight of the pool; the other is to use concrete anti-floating piles at the bottom of the pool. Or add anti-floating piles on the side. [0003] Disadvantages of the prior art: (1) The amount of excavation in civil construction is large, and the work is difficult; (2) The total amount of concrete is large, and the construction cost is high; (3) The water temperature of the pool is poor in fluidity and the temperature is uneven; (4) The heat dissipation of the pool in winter Large, the water temperature fluctuates greatly. SUMMARY OF THE INVENTION [0004] In o...
