Abstract

The invention provides a surrounding and drilling integrated platform construction method. The construction method comprises the following steps that a cofferdam is erected; a quadrangle gauge pile isdriven into water, wire drawing is carried out, a steel sheet pile is driven in along a drawn wire; the cofferdam is strengthened to form a pile driving platform; brackets, H-type steel, box iron anda framing scaffold are installed on the inner side of the steel sheet pile; a cast-in-place pile is poured; a guide frame is arranged in the cofferdam, a protection barrel is embedded according to the guide frame, a pile driver is lifted on the platform to drive the cast-in-place pile, hole drilling and hole cleaning are carried out, and reinforcing steel bars are arranged in the protection barrel for concrete pouring; a bearing table and a stand column in-water part are constructed; after the cast-in-place pile is poured, a platform distributive girder, a bearing beam and the brackets are dismounted, the protection barrel is pulled out, water extraction and leaking stoppage are carried out in the cofferdam, the framing scaffold and supports are additionally arranged, a foundation trenchis dug, a pile head of the cast-in-place pile is removed through chiseling, and formwork erecting is carried out to pour the bearing table and the stand column in-water part; the cofferdam is removed;and the steel supports and the framing scaffold are dismounted, and the steel sheet pile is pulled out. The surrounding and drilling integrated platform construction method solves the problems that the process is relatively complex, and the economical input is large.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction method for an integrated platform surrounding a drill. Background technique [0002] Most of the bridge projects are river-crossing bridges, so it is inevitable to carry out piling in deep water, pouring caps and columns. This is a difficult point in the construction of bridges spanning deep water rivers, which is related to the cost, progress, safety and quality of construction. [0003] The usual method is to set up a temporary piling platform first, which is composed of steel pipe piles and section steel, then bury the underwater casing, set up a pile driver on it to erect the cast-in-place piles in the water, and then remove the piling platform, according to the size of the pile cap (plus the working width) and water depth to choose an appropriate method for cofferdam in water (single-layer, double-layer Larsen steel sheet pile, double-wall steel c...
