Ring prevents dropping situations by the plug-in hanging point to quartering hammer end of safety rope.
A kind of earth-filling method, follows the steps below:
Step 1: the backfill material for being used to fill out sinkhole is poured into construction site by dumper；
Step 2: the soil body is elapsed to backfill position by the stress transfer conehead 3 of excavator end, then passes through stress
The stress plate that transmitting conehead 3 connects carries out layering to the backfill material in backfill hole and hits reality, up and down poor position compacting；Make to backfill in hole
The compactness of backfill material reaches 95%；
Step 3: in the case where the later period is by flood season and rainfall larger situation, road pavement backfill point is investigated, if any hair
Heavy situation is given birth to, continues to be backfilling and compacted, until backfilling surface without ponding and pavement strength hardly happens variation.
In the step 2 when being tamped to backfill material, according to upper offline position movement acting, left and right overlap joint, overlapped points
Spacing is tamped in blossom type and taking exercises.
Earth's surface originates to 30m the sinkhole for vertically handling depth, including shallow-layer goaf, the backfill of 2m or more strip footing,
City planting ductwork existing structure body nearby backfills, without being limited by topography variation.
Uniform geology section, is handled using board-like tup.Uneven geology section uses, and spherical conehead is handled.It is broken
Stone soil and the gravel soil body, are handled using bevel-type tup.Backfill is expanded to coffin pit or inclined gallery, using vibration rod is adjusted, is carried out
Processing.
Using the original state soil body, conehead is placed on backfill medium by machinery operator, is pushed in the soil body to cavity, is reached
Acting end is placed at the top of the backfill soil body by 50cm or so, is carried out acting and is hit reality.Reach pre-control index to settling amount and deflection
When, next layer of backfill operation can be carried out.
Feature: overturning traditional processing method, not by regional impact, backfills in the treatment process of paragraph position, utilizes original state
The soil body while save the cost, can use compactness and deformation quantity, and two-way index carry out compacting control.
Above embodiments are only to of the invention for example, do not constitute the limitation to protection scope of the present invention,
Within the same or similar design of all and present invention all belongs to the scope of protection of the present invention.
