Ⅰ. Mud shielding wall formed piles

Forward and reverse circulation bored piles: Forward circulation is that the flushing fluid is sent to the bottom of the hole by the mud pump through the drilling rod, and then returns to the ground from the bottom of the hole; the reverse circulation flushing fluid is exactly opposite to the forward circulation route.
1 、 Applicable soil conditions: clayey soil, silt, fine sand, medium sand, coarse sand, soil with a small amount of gravel and pebbles (content less than 20%).
2、Application scope: construction engineering; road and bridge engineering; municipal engineering.

Percussive Drilling Hole Filling Pile: Mechanical drilling, steel pipe squeezing or human excavation to form pile holes in

foundation soil.

1、Applicable soil conditions: clayey soil, powder soil, sandy soil, fill soil, gravel soil and weathered rock layers.

2、Application scope: construction engineering; road and bridge engineering; municipal engineering.

1、Applicable soil conditions: clayey soil, powder soil, sandy soil, fill soil, gravel soil and weathered rock layers.

2、Application scope: used in municipal construction, highway and bridge, industrial and civil construction, underground

diaphragm wall, water conservancy, prevent seepage, protect slope and other foundation construction.

2、Application scope: civil and industrial buildings above the water table of the general cohesive soil, sandy soil and artificial landfill foundation.

(2) Bored hole expanding bottom grouting pile: Firstly, use ordinary bored pile drill bit to follow the general drilling method to drill into the designed holding layer according to the diameter of the pile body, then extract the drilling tools and replace the ordinary drill bit with special expanding bottom drill bit to the bottom of the hole to form an expanding head by expanding the diameter of the pile bottom.

First use an ordinary bored pile drill bit to follow the general drilling method to drill according to the diameter of the pile body to the designed bearing layer, then extract the drilling tool, replace the ordinary drill bit with a special bottom-expanding drill bit to the bottom of the hole, and expand the diameter of the pile bottom to form an expansion head.

1、Applicable soil conditions: hard, hard-plastic clayey soil above the water table and sand and gravel weathered rock layers above the middle density.

2、Application scope: civil and industrial buildings above the water table of the general cohesive soil, sandy soil and artificial landfill foundation.
