Embodiment Construction

[0011] figure 1 As shown, the deep water exposed bedrock rock-socketed pile construction artificial foundation pile stabilization technology refers to using bagged gravel 1 and bagged sand or soil 2 to form an artificial foundation with thickness Y and slope X. After the pile foundation (steel pile or other prefabricated pile or casing) is laid, the water flow and waves have a great influence on the stability of the pile foundation, so it is necessary to carry out stability calculation first to solve the minimum depth h of the pile into the soil, so as to determine the Artificial bed thickness Y.

[0012] The shape of the artificial foundation bed has a small top surface and a large bottom. The distance B between the top edge line of the artificial foundation bed and the pile center line should be greater than 2 to 2.5 times the pile diameter, and the slope X around the foundation bed is 1:2 to 1:3. The top layer, the bottom layer and the periphery of the throwing material ar...

Abstract

The invention relates to an artificial base stabilizing technique of deep-water expose base rock embedded post, wherein said stabilizing technique comprises: it forms artificial base at the thickness as Y and the edge slope as X via packing sands and stones with bags at the exposed base rock, while Y should be higher than the minimum soil-embed depth of post base; then pouring bagged stones at its bottom, top and around edge, at 1-3m thickness; and the thickness of bagged sand or soil at the middle layer, S=Y-the thickness of around bagged stone as 2-6m; the incline degree of slope is 1:2-1:3. Compared with present technique, the invention has short time, lower cost and high quality.

Description

technical field [0001] The invention belongs to the pile foundation engineering technology in the field of construction, in particular to a pile stabilization technology using an artificial foundation bed during the construction of pile foundations such as wharves and bridges in the deep-water exposed bedrock environment. Background technique [0002] Building foundation engineering is the foundation of buildings, and pile foundations are the foundation forms often used in various buildings. For major engineering projects such as wharves and bridges, due to the influence of seabed topography, the bedrock is buried shallow or basically exposed, which is not enough to form Stable geological conditions for pile foundations. To carry out rock-socketed pile construction in the above-mentioned exposed bedrock, pile stabilizing measures must be adopted to meet the conditions for the self-stabilization of the pile foundation (pile or casing) and subsequent construction. The referen...
