Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a pile foundation with a shear-resistant structure and a pile foundation engineering construction method. BACKGROUND

[0002] Large equipment is usually installed on an equipment foundation, which should meet the requirements of bearing capacity and normal use. In the case that natural foundation and other foundation treatment schemes cannot meet the design requirements, using a pile foundation is a reliable method. The pile foundation generally uses a concrete precast square pile or a prestressed reinforced concrete pipe pile, which has higher vertical bearing capacity and lower horizontal bearing capacity. For equipment foundations that bear large horizontal loads, such as wind tunnel equipment foundations, which often bear several hundred tons of horizontal loads, a pile foundation alone cannot meet the horizontal stress requirements. Moreover, the shear resistance of the pile foundation is usually low, and the efficiency of the pile foundation in bearing the bending moment effect of the foundation is relatively low.

[0003] In view of the problems in the related art, no effective solution has been proposed so far. SUMMARY
