Embodiment Construction

[0055] Taking a commercial building as an example, the building has three floors underground, including a parking garage, equipment rooms and two floors of commerce, and the seven floors above ground are commercial and commercial management rooms and warehouses. The overall construction technology of this project adopts the full reverse construction method, and the underground diaphragm wall (two walls combined into one) is used as the vertical enclosure structure around the foundation pit. The upside-down construction area utilizes structural beams and slabs as horizontal support members.

[0056] The foundation design grade of this project is Grade A, and the engineering piles are bored concrete pouring piles, with a pile diameter of 1200mm and 1500mm, a total of 131 piles, the bearing layer at the pile end is (5)-2 medium weathered andesite, and the pile length is about 23m. The elevation of the foundation floor is -15.7m, the thickness of the floor is 700mm, and the thickn...

Abstract

The invention discloses a pile column connection precise positioning pouring system and a construction method. The pile column connection precise positioning pouring system comprises a steel stand column, a drilled pile, a control frame connected to a supporting platform, a first jack connected between the control frame and the horizontal direction of the steel stand column, a second jack connected between a protective cylinder and the horizontal direction of the steel stand column, and a feeding pipe inserted into the steel stand column. During construction, by arranging the control frame, the steel stand column can be effectively borne; by arranging the supporting platform, the supporting platform can be fixedly connected through a bearing arm pre-connected to the steel stand column; by arranging the first jack and the second jack, installation is facilitated, and adjustment, clamping and fixing are facilitated; and the first jack and the second jack are jointly controlled through a verticality adjusting controller, so that cooperation and synchronous control are facilitated. Through pouring construction of different grades of concrete, the overall construction of the steel stand column and the drilled pile is guaranteed, and effective construction during concrete grade conversion and precision control in the process are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pile foundation construction, and in particular relates to a pouring system and construction method for precise positioning of pile connection. Background technique [0002] With the development of construction engineering and the improvement of styles, buildings or structures have higher and higher load-bearing requirements for the lower foundation, and pile foundation, as a widely used foundation form, can carry most of the upper buildings and structures load. In the existing construction, in the pile foundation, each frame column is supported by a large-diameter cast-in-situ pile, which is called a construction form of one column and one pile. And the verticality control of the column piles in one column and one pile has always been a difficult point and the focus of technical research. Especially when the verticality requirements are high, the existing adjustment equipment is difficult to meet the a...
