Description
Technical field
The present invention relates to the realm of building construction, more specifically to a kind of construction backfill rammed earth auxiliary with advance
Bury rod.
Background technology
In construction, foundation ditch（Groove）Backfill is sunk and backfill percolating water causes the common manifestation of setting of ground to be
Ground part or sheet is caused hollowing, crack occur, deform, collapse and wall body slit.
It is common technological difficulties in construction that backfill, which is sunk, causes the reason for backfill is sunk more, substantially has
The earth material moisture content that backfill is selected is big, and clay soil property into " spongy soil ", backfill during compacting into not making the originals such as compaction in layers
Cause.In the inspection soil property technique of backfill, whether backfill particle diameter meets regulation, and whether examines backfill soil's water content
In control range, such as moisture content is higher, can be using measures such as scarifying, drying or uniform incorporation dry ground；Such as containing for backfill
Water is relatively low, can be using measures such as watering wettings in advance.But in practical operation, due to external environment change and construction when
Between difference, examine place Min layers soil after soil property technique, backfill soil's water content changes in technique of raking, then influence
It is ensuing to pound densification process and levelling acceptance checking technology.Cause final backfill sinkage.
The content of the invention
1. the technical problem to be solved
For problems of the prior art, used it is an object of the invention to provide a kind of construction backfill rammed earth auxiliary
