Rock-socketed steel dock structure and construction method thereof

Abstract

The invention discloses a rock embedded steel frame dock structure. The structure comprises an upper structure (5) of the dock and a plurality of tubular upright posts (11) arranged under the upper structure (5) of the dock, wherein the lower ends of the upright posts are fixedly connected with a rock matrix through rock-embedded piles(2). Horizontal supports (13) and oblique supports (14) are arranged between the upright posts (11). The invention also discloses a method for constructing the rock embedded steel frame dock structure. The method comprises the following steps: firstly, making a steel frame (1) in a proper field, and welding and fixing the upright posts (11) with the horizontal supports (13) or the oblique supports (14); secondly, placing the steel frame (1) on a flattened leveling course (33); thirdly, taking the steel frame (1) as a construction platform and mounting a drilling machine to drill the rock matrix; fourthly, inserting the rock-embedded piles (2) with the upright posts (11) serving as sleeves for the rock-embedded piles (2). The dock structure constructed by the method has the advantages of strong adaptability to horizontal load, high entire rigidity, and quick construction speed.

Description

technical field [0001] The invention relates to a pile foundation engineering technology in the field of construction, in particular to a pile stabilization technology and a construction method used in the construction of pile foundations such as wharves and bridges in the deep-water exposed bedrock environment. Background technique [0002] When the construction of a large-scale open wharf in the open sea encounters a geological environment with exposed bedrock or a shallow bedrock overlay, the gravity caisson structure is generally preferred, but this structure has a high wharf surface, a large amount of underwater engineering, and mooring There are disadvantages such as poor stability conditions and influence on the flow state of the water area. If the high-piled rock-socketed wharf structure is used, although the gravity-type caisson structure has high wharf surface, poor mooring stability conditions, and influence on the flow state of the water area, it is necessary to ...

Problems solved by technology

[0002] When the construction of a large-scale open wharf in the open sea encounters a geological environment with exposed bedrock or a shallow bedrock overlay, the gravity caisson structure is generally preferred, but this structure has a high wharf surface, a large amount of underwater engineering, and mooring Disadvantages such as poor stability conditions and influence on the flow regime of the water area

If the high-piled rock-socketed wharf structure is used, although the gravity-type caisson structure has high wharf surface, poor mooring stability conditions, and influence on the flow state of the water area, it is necessary to install pile stabilization measures during the construction period, and the structural level changes. Large site, large amount of underwater engineering and other deficiencies, the typical structural section see figure 1
