Embodiment Construction

[0019] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0020] A construction method of a high-pressure rotary grouting pile enclosed by an underground diaphragm wall of a sluice chamber, comprising the following steps:

[0021] Step 1. Stake out the pile position. According to the control point of the wire and the pile position layout diagram of the design drawing, after completing the stakeout of the sideline of the lock chamber, the distance is determined to determine the pile position, and each pile position is inserted with a wooden pile and sprinkled with white ash for marking;

[0022] Step 2, positioning the drilling rig, moving the pile driver to the marked position of one of the wooden piles, aligning the center of the drill bit with the pile position, and leveling the drilling rig after the drilling rig is...

Abstract

The invention relates to the field of hydraulic engineering construction, in particular to a construction method of a lock chamber underground continuous wall enclosed high pressure jet grouting pile of a lock chamber. The construction method is characterized by comprising the following steps: step 1, pile lofting; step 2, drilling machine positioning; step 3, grout preparing; step 4, drilling and reaming; step 5, jet grouting accelerating; step 6, drilling machine shifting; and step 7, washing. The construction method has the beneficial effects that the underground continuous wall enclosure structure is high in stability, the equipment damage rate is low, the construction period is short, and the cost is low.
