Embodiment 1

[0028] Embodiment 1: as figure 1 As shown, a swirl pool is provided with an external cantilever ring beam 1 at the junction of the inclined cone 2 and the outer cylinder 3 . This swirl pool is constructed according to the following steps: (1) Excavate the foundation pit to the bottom of the outer cylinder 3; (2) construct the outer ring beam 1; (3) the outer ring beam 1 is the foundation of the outer cylinder 3 construction stage , construction outer cylinder 3; (4) cut water and support soil retaining body 4, construct inclined cone 2 and bottom plate 10; (5) construct pillar 5, inner cylinder 6, pump room layer 7 and roof layer 8 from bottom to top.

[0029] Such as figure 2 As shown, when the present invention is working, the earth pressure acts vertically on the lower surface of the inclined cone 2 and the bottom plate 10, and the outer hanging ring beam 1 constrains the top of the inclined cone 2, and the top of the inclined cone 2 generates an outward thrust, and the o...

Embodiment 2

[0030] Embodiment 2: as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the lower part of the inclined cone 2 and the bottom plate 10 is provided with a group of bolts 9 anchored in the rock and soil. The bolt groups 9 are manufactured by high-pressure grouting technology. Other structures and construction methods of this embodiment are the same as those of Embodiment 1.

Abstract

The invention relates to a swirl pool, comprising an inclined cone (2) and an outer cylinder (3), the key point of which is that the inclined cone (2) and / or the outer cylinder (3) are additionally provided with at least one protruding ring beam (1). The present invention also relates to the construction method of the swirl pool. The invention has strong anti-floating ability, low investment, and can exert the force transmission effect of the arch body of the inclined cone, reduce the thickness of the outer cylinder and the inclined cone, and the whole structural system has reasonable layout, simple force transmission, and coordinated rigidity; at the same time, The invention can reduce the earthwork excavation operation surface of the foundation pit, reduce the difficulty of precipitation, and provide conditions for slope stability.

Description

technical field [0001] The invention relates to a swirl pool structure system and a construction method for the swirl pool, and belongs to the technical field of structural engineering mainly constructed of concrete. Background technique [0002] In the construction of iron and steel enterprises, the swirl pool is an important part of the water treatment system. It has the characteristics of large diameter, deep embedding, difficult precipitation, difficult anti-floating design, large concrete volume, high cost, and long construction period. [0003] The structural system of the swirl pool includes an outer cylinder, an inner cylinder, a roof layer, a pump room layer, pillars, inclined cones, and a bottom plate. The pump room layer and the roof layer are supported between the inner and outer cylinders, the former places the water pump equipment, and the latter seals the swirl pool. The vertical loads of the inner cylinder, the pump house floor and the roof floor are transmi...
