Method for reinforcing deep backfill foundation through deep grouting and steel pipe piles
The invention belongs to the technical field of deep backfill soil reinforcement, discloses a method for reinforcing a deep backfill foundation by using deep grouting and steel pipe piles, and aims to solve the problem of settlement caused by the fact that deep backfill soil below cannot be reinforced through the steel pipe piles due to the fact that the steel pipe piles cannot transmit loads to deep backfill soil bodies below 9m. The method comprises the following steps: (1) measuring and setting out to determine the position of a pile hole; (2) a drilling machine is in place; (3) drilling a hole by a drilling machine to form a pile hole; (4) a grouting pipe is lowered into the pile hole; (5) steel pipe piles are implanted into the pile holes; (6) filling the steel pipe pile with granite; (7) pouring to the lower pile hole through a grouting pipe; and (8) pouring the steel pipe pile. According to the deep backfill soil reinforcement device, deep backfill soil located on the lower portion can be reinforced, the problem that the steel pipe pile cannot reinforce the deep backfill soil located on the lower portion is solved, and therefore it is ensured that the backfill soil at all the depth positions of the deep backfill soil can be reinforced, and the reinforcement requirement of a deep backfill foundation is met.
本发明属于深厚回填土加固技术领域，公开了一种利用深部注浆和钢管桩加固深厚回填地基的方法，为了解决钢管桩无法将荷载传递到9m以下的深厚回填土体导致下方的深厚回填土无法通过钢管桩进行加固而出现沉降的问题。本发明包括(1)测量放线确定桩孔位置；(2)钻机就位；(3)钻机钻进成孔形成桩孔；(4)向桩孔内下放注浆管；(5)向桩孔内植入钢管桩；(6)向钢管桩内填充米石；(7)通过注浆管向下部桩孔浇筑；(8)浇筑钢管桩。本发明能够对位于下部的深厚回填土进行加固，解决了钢管桩无法对下部的深厚回填土进行加固的难题，从而确保深厚回填土各个深度位置的回填土都能够进行加固，从而满足深厚回填地基的加固需求。
