Abstract

The invention discloses a reverse construction method for a pebble foundation swirling well. The construction method comprises the following steps: 1), measuring and positioning to determine the positions of a center, a well wall and a top beam of the swirling well; 2), excavating earthwork to form foundation pits of first section of well wall and the top beam; 3), binding top beam reinforcement and the first section of well wall reinforcement; 4), installing the top beam and an inner side mould board of the first section of well wall; casting concrete, so that the top beam and the first section of well wall form an integer; 5), forming a foundation pit of the second section of well wall; 6), binding second section of well wall reinforcement, connecting the upper end of a vertical reinforcement in the second section of the well wall reinforcement with a lower vertical preserved reinforcement of the first section of well wall reinforcement; 7), installing the inner side mould board of the second section of well wall, and casting the second section of well wall; 8), repeating the steps 5) to 7), until the construction for all well walls is completed; and 9), finishing the construction of a concrete structure inside the well. The reverse construction method is simple and easy, high in efficiency, convenient to control engineering quality, safe and reliable.

Description

technical field [0001] The invention relates to a reverse construction method of a swirl well, in particular to a reverse construction method of a pebble foundation swirl well. Background technique [0002] Usually, the caisson sinking method is used for the construction of the swirl well, which has strict requirements on the geological conditions and the construction site, and it is difficult to guarantee the quality requirements, and there are many potential safety hazards. Especially under the conditions of pebble foundation, the bearing capacity of the foundation is relatively high, and the caisson cannot sink. Therefore, it is necessary to study a new construction method of the swirl well. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides a pebble foundation swirl well reverse construction method which is convenient for engineering quality control. [0004] The technical solution adopte...
