Combined type foundation pit supporting pile structure
The invention discloses a combined type foundation pit supporting pile structure. The combined type foundation pit supporting pile structure is composed of high-pressure jet grouting piles, cast-in-situ bored piles and a top beam. The high-pressure jet grouting piles which are engaged with one another and have large diameters are taken as a foundation pit waterproof curtain. The cast-in-situ bored piles are used as foundation pit supporting piles. The high-pressure jet grouting piles are constructed firstly, so that the waterproof curtain is formed; after the quality of the high-pressure jet grouting piles is almost stable, the cast-in-situ bored piles with small diameters are constructed again at the same positions as the high-pressure jet grouting piles, and it is guaranteed that the cast-in-situ bored piles are internally tangent to the high-pressure jet grouting piles on the sides close to a foundation pit on the premise that the portions, engaged with one another, of adjacent high-pressure jet grouting piles are not occupied during construction of the cast-in-situ bored piles; and finally, the top beam is arranged at the tops of the piles, and thus the purpose of supporting the foundation pit and the waterstop purpose are achieved. By the adoption of the combined type foundation pit supporting pile structure, the construction space of the foundation pit supporting structure can be effectively reduced. The combined type foundation pit supporting pile structure is particularly suitable for a foundation pit supporting project under the land shortage condition; due to the fact that the cast-in-situ bored piles with the small diameters are internally tangent to the high-pressure jet grouting piles with the large diameters, the combined effect of the two kinds of piles can be brought into full play.
