Problems solved by technology
[0003] In order to solve the above-mentioned problems that the prefabricated concrete pile has a large soil squeezing effect and the cost of the steel pipe pile is relatively high, the present invention provides a steel pipe pile that is more economical in cost, has the same soil squeezing effect as the steel pipe pile, and is smaller than the prefabricated concrete pile. , low environmental pollution, good bearing capacity and quality, suitable for the underpinning and strengthening of existing building foundations. And use the static pressure anchor bolt construction technology pile sinking

The invention discloses a combined anchor-rod static pressure pile which has the advantages of a precast concrete pile and a steel pipe pile. The combined anchor rod static pressure pile is characterized in that a pile body is composed of an upper precast concrete pile and a lower steel pipe pile; and in the process of preparing the combined anchor rod static pressure pile, a pile sinking construction process is implemented by using an anchor rod static pressure method, and comprises the following steps: pressing the steel pipe pile part of the combined pile, carrying out construction on a joint of the precast concrete pile and the steel pipe pile; and pressing the precast concrete pile part of the combined pile. The combined anchor rod static pressure pile provided by the invention has the advantages of high bearing capacity of single pile, good quality of pile body, economical cost of construction, and small compaction effect and environmental hazard in the process of pile sinking construction, and the like, therefore, the combined anchor rod static pressure pile is suitable for the underpinning and reinforcement of foundations of the existing buildings.
Description
technical field [0001] The present invention relates to the field of civil construction engineering, and in particular to an anchor static pressure composite pile suitable for underpinning and strengthening of existing building foundations. The pile body is formed by connecting an upper prefabricated concrete pile with a lower steel pipe pile. And adopt the bolt static pressure method construction technology pile sinking. Background technique [0002] Anchor static pressure piles have the advantages of light and simple construction equipment, small operating space, no vibration, no noise, and clear force during construction, and are widely used in existing building foundation underpinning projects. Anchor static pressure piles generally adopt prefabricated concrete piles or steel pipe piles. Prefabricated concrete piles have high bearing capacity, good pile body quality, and relatively low cost, but the soil squeezing effect is more obvious during construction, which has a ...
