Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an integrated machine for mixing and conveying precast square pile concrete. Background Technology

[0002] Precast square piles are square-section concrete piles that are prefabricated in a factory or prefabrication site. The main functions of precast square piles include:

[0003] Enhancing Foundation Bearing Capacity: Piles transfer building loads to deep, stable soil layers, suitable for soft foundations or reclaimed areas. Controlling Foundation Settlement: Reduces total and differential settlement. In one industrial plant, the uneven settlement decreased from 5cm to less than 1.2cm after using square piles. Enhancing Seismic Performance: The pile-soil interaction system can dissipate seismic energy. In 2021, a project in an area with a seismic fortification intensity of 8 degrees saw a 40% reduction in structural seismic damage index after using square piles. Optimizing Construction Efficiency: Compared to cast-in-place piles, the construction cycle is shortened by approximately 50%. A commercial complex project using static pressure square piles achieved a maximum daily pile driving volume of 80 piles. Reducing Environmental Impact:

[0004] No mud discharge, and noise levels are reduced by 30 dB compared to cast-in-place piles. A hospital renovation and expansion project used square piles, successfully avoiding interference with the medical area. Cost savings: The overall construction cost is 15%–20% lower than cast-in-place piles, and subsequent maintenance costs are reduced by 60%. A residential project using square piles reduced its total life-cycle cost by 18%.

[0005] However, in practical applications of existing technologies, especially in the manufacturing process of precast square piles, concrete mixing and transportation are two key links. Traditional construction methods often require the separate use of concrete mixers and concrete pumps, which not only increases the procurement cost of equipment but also reduces construction efficiency.
