[0018] Hereinafter, the present invention will be further described through embodiments in combination with the drawings.
[0019] Such as Figure 1 to Figure 4 As shown, a pre-treatment method for the pile foundation of a coastal soft foundation sluice. Before the construction of the sluice pile foundation, the soft soil foundation of the sluice is treated first, and the entire sluice area is divided into the upstream connection area 1, the downstream connection area 3, and the left bank connection area 4. , Right bank connection area 5 and gate chamber foundation 2, each area adopts vacuum preloading; vacuum preloading horizontal drainage adopts cushion layer 10 to directly connect drainage filter pipe 12 for drainage; vertical drainage adopts drainage inserts, and the drainage inserts are square. Or triangular arrangement, 0.8m~1.0m apart, and the exposed mud surface is about 50cm. Upstream connection area 1, downstream connection area 3, left bank connection area 4, right ba...
