Description

Deep dynamic compaction composite foundation in rocket hammer hole

Technical Field

The utility model belongs to the technical field of composite foundation, especially, relate to a deep dynamic compaction composite foundation in rocket hammer hole.

Background

The dynamic compaction method is generally adopted for processing loose backfill soil and soft soil foundations, a rammer above ten tons needs to be lifted for a certain height, the foundation is tamped by means of free falling of the rammer, the backfill material of 2.

The existing rocket hammer hole deep dynamic compaction composite foundation adopts backfill materials of 2.

Therefore, the deep dynamic compaction composite foundation in the rocket hammer hole is very necessary to be invented.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a deep dynamic compaction composite foundation in rocket hammer hole to solve the backfill material of the downthehole deep dynamic compaction composite foundation of current rocket hammer and adopt 2. A deep dynamic compaction composite foundation in a rocket hammer hole comprises a soil layer, a plurality of pile holes and a backfill layer, wherein the pile holes are formed in the soil layer, and the upper ends of the pile holes penetrate through the upper layer of the soil layer; the backfill material layer is multiple and is arranged inside the pile hole.

Preferably, the soil layer comprises various soil base layers such as miscellaneous fill, weak soil, liquefaction, wet collapse and the like.

Preferably, the pile holes are uniformly distributed on the soil layer and are arranged in a square or quincunx shape, the diameter d of each pile hole is 0.6-1.2 m, and the distance a between the pile holes is 2-3 times of the diameter d of each pile hole.

Preferably, the diameter of the backfill layer is equal to that of the pile hole, and the backfill of the backfill layer is a mixture of broken bricks and tiles, concrete blocks, broken stones, lime soil, building residue soil, industrial residue and the like.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses a setting on backfill layer, backfill layer's backfill adopts mixtures such as broken brick tile, concrete piece, rubble, lime-soil, building dregs, industrial waste residue, realizes the recycle of building rubbish, inorganic solid waste material, reduces composite foundation's cost, accords with energy-concerving and environment-protective requirement.

The utility model discloses a setting in stake hole, the lower extreme in stake hole adopt the backfill layer to fill, have that the crowded dense effectual of stake hole week soil, the processing degree of depth is big, and composite foundation rigidity advantage such as even improves composite foundation's bearing capacity.
