Problems solved by technology

[0002] Generally, the caisson sinking method is used for the construction of the swirling well, which has relatively high requirements on the geological conditions and the construction site. During the sinking process, the surrounding soil will subside, which poses many safety hazards to the surrounding buildings.

Embodiment Construction

[0031] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0032] The continuous casting machine swirl pool of Hebei Jingye 150t converter phase II project is located between the 13th and 14th lines of the BC span of the newly built main building, close to the main building column foundation, and the depth reaches -18.100m, according to the actual situation on site and the overall progress of the project , it was decided that the outer wall of the shaft should be constructed using the semi-inverted construction method.

[0033] See Figure 1 to Figure 6 .

[0034] The above-mentioned swirl well semi-reverse construction method comprises the following steps:

[0035] 1) Measurement and positioning, determine the position of the center point of the swirl well, the well wall 1 and the position of the ...

Abstract

The invention discloses a semi-inverse construction method of a cyclone well. The method comprises the following steps: 1) measuring, positioning and determining the center and the position of the well wall of the cyclone well; 2) firstly excavating the uppermost joint of well wall foundation pit; 3) performing earth excavation on the second section for forming the second joint of the well wall foundation pit; 4) binding the second joint of well wall steel bars; 5) mounting the second joint of well wall inside formwork; 6) pouring the second joint of well wall concrete; 7) completing the earth taking of the third section for forming the third joint of the well wall foundation pit; 8) binding the third joint of the well wall steel bars; 9) mounting the third joint of the well wall inside formwork; 10) pouring the third joint of well wall; 11) repeating the steps 8)-10) till the construction of the lowermost joint of the well wall is completed; 12) repeating the steps 9)-10) to complete the construction of the uppermost joint of the well wall; and 13) completing the construction of a concrete structure in the well.The method is suitable for construction environments which have better geological conditions and are limited by surrounding conditions.

Description

technical field [0001] The invention relates to a construction method of a swirl well, in particular to a semi-reverse construction method of a swirl well. Background technique [0002] Generally, the caisson sinking method is used for the construction of the swirl well, which has relatively high requirements on the geological conditions and the construction site. The surrounding soil will subside during the sinking process, which poses many safety hazards to the surrounding buildings. At present, reinforced concrete cast-in-situ piles or underground diaphragm walls are often used as supporting structures, and swirl well construction can be carried out in construction areas with poor geological conditions. Successful examples. However, the geological conditions are relatively good, and due to the limitation of the surrounding conditions, the subsidence method cannot be used for construction. Considering the construction technology and engineering cost, it is necessary to ex...
