Pile hammer foundation classification

2020-11-12

Pile cap position of pile hammer

①Pile foundation of high pile cap the bottom edge of pile cap is higher than the ground, and its stress and deformation are different from that of low pile cap pile foundation. It is generally used in road, bridge and wharf engineering.

②Low pile cap pile foundation the bottom edge of pile cap is lower than the ground, which is generally used in housing construction.

Load bearing characteristics

①End bearing pile - refers to passing over the soft soil layer and transferring the load of the building to the hard soil layer or stone layer at the pile end according to the pile. The friction effect of the soft soil on the pile body is small, and the sliding friction force can be ignored.

Friction pile refers to the pile sinking into a certain deep layer of soft soil layer. According to the friction effect of pile side soil, the upper load is transmitted and diffused to the soil near the pile. The soil at the pile tip also acts as a supporting column. When the soil of the supporting column at the pile tip is very compact, and the pile has a certain relative deviation from the soil, it has the function of friction pile.

Raw materials for pile shaft

①Reinforced concrete pile

Reinforced concrete piles can be prefabricated components and cast-in-place floor slabs. According to the scheme design, the pile length and Section specification can be selected at will.

②Steel pile

Generally, there are 250 ~ 1200mm steel sheet piles and wide wing I-shaped steel piles. The bearing capacity of steel pile is very large, lifting, transportation, pile sinking and pile connection are convenient and fast, but the steel consumption is much, and the project budget is high. At present, it is only used in very few top priority projects in China. For example, in the project of Shanghai Baoshan Iron and steel complex, many steel sheet piles with diameters of 914.4mm and 600mm and lengths of about 60cm are used for the important and high-speed running mechanical equipment foundation and column foundation.

③Stump

It has been rarely used, only in some engineering structure reinforcement or temporary engineering projects that can be adapted to local conditions. Under the ground temperature, the wood has good performance index, but in the geographical environment of alternate dry areas, it is easy to corrode.
