Description
Technical field
The present invention relates to a kind of compacting method for backfilling foundation pit, specifically with the compacting side of rock drill backfill foundation pit
Method.
Background technology
In the engineering constructions such as previous architectural engineering, municipal works, foundation pit backfill construction quality is often difficult to control, especially
It is not easy to the space of operation in narrow, dangerous and personnel, and backfill quality is even more to be difficult to ensure that construction of structures throwing often occur
After entering use, there is soil body sedimentation, the affiliated facilities such as its step, ramp is caused to open due to backfilling leakiness in the foundation pit on periphery
Phenomena such as splitting, sinking；What is more in Municipal Road Engineering construction, the pipeline, inspection shaft and the structure that are arranged under road
Object since its groove space is narrow, dangerous, is not easy to construction personnel's operation, and backfill construction especially compaction in layers is frequently present of
Carelessness carries out, and road is caused to be open to the traffic using soon, road surface differential settlement occur in well lid periphery and pipeline position, to vehicle
It is current to cause some potential safety problems.
The content of the invention
It is contemplated that the defects of overcoming the prior art, provides a kind of compacting method with rock drill backfill foundation pit, solves
The problem of effect is poor can not be tamped or be tamped to narrow and hazard space, it is ensured that narrow space tamps quality.
In order to solve the above-mentioned technical problem, the present invention is realized in：
A kind of compacting method with rock drill backfill foundation pit, it is characterised in that it includes the following steps：
Step 1：Foundation pit backfilling material is inserted in foundation pit narrow space, when filling thickness is inconsistent, backfilling material is spread out；
Step 2：Tamping plate is installed on the bore bit of rock drill；
Step 3：Rock drill is started shooting, and backfilling material is rammed with rock drill, is rammed and is stacked when ramming, and overlapping area is no less than 1/3,
Each tamping point is rammed no less than 6-8 and is hit, while ramming using the mechanical large arm of rock drill be downwardly applied to pressure for aid in rammer
Real, each tamping operation face is rammed no less than twice；
Step 4：Symmetrical backfill construction is carried out, one layer is rammed in structure both sides or the symmetrical back-filling in layers compacting of surrounding, backfill and finishes
Afterwards, compactness detection is carried out in time, and after meeting design requirement, record, which is rammed, hits number and pass；
Step 5：Above each layer backfill is rammed, and is operated by the pass of record, until design altitude is backfilled to, it is tight during ramming
Taboo rams plate touching underground structure.
The compacting method with rock drill backfill foundation pit, it is characterised in that：The tamping plate includes one block of steel plate, the steel
Four angle kerve of plate, hot-working make its four side bend downward 10 °, and corner incision is closed up and welded, piece steel of steel plate lower weld
Stick, the steel plate lower end diameter is identical with rock drill bit diameter, and reinforcement steel plate is welded between steel plate and rod iron.
The compacting method with rock drill backfill foundation pit, it is characterised in that：Back-filling in layers thickness is 500-600mm.
The beneficial effects of the invention are as follows：By installing tamping plate additional in rock drill fibre head, and generated using it in operation process
Impact energy and large arm can flexibly and comfortably into narrow, hazard space the characteristics of, with successfully solving in engineering construction
Under narrow, hazard space back-filling in layers compacting quality it is bad the problem of.
This method practicality simply is easy to grasp, and good application effect, operating efficiency is high, improves underground narrow space backfilling working
Efficiency and earthwork compacting construction quality, can effectively eliminate the danger that underground is narrow, hazard space is brought to operating personnel's operation,
It is simple in structure, it is operated convenient for grasping, is easy to materials processing, processing cost is low, and popularizing application prospect is wide.
Description of the drawings
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the structure diagram of four angle kerve of steel plate of tamping plate of the present invention.
Fig. 2 is the structure diagram after four angle kerve of the steel plate welding of tamping plate of the present invention.
Fig. 3 is the structure diagram of tamping plate of the present invention.
Specific embodiment
As shown in Figure 1：A kind of compacting method with rock drill backfill foundation pit, it includes the following steps：
Step 1：By foundation pit backfilling material（Usually element soil）It inserts in foundation pit narrow space, when filling thickness is inconsistent, will return
Filling chock material, which is spread out, makes its basically identical；
Step 2：Tamping plate is installed on the bore bit of rock drill；The tamping plate includes one block of steel plate 1, four angle kerve 2 of steel plate, heat
Processing makes its four side bend downward 10 °, and corner incision is closed up and welded, piece rod iron 3 of steel plate lower weld, the steel plate lower end
Diameter is identical with rock drill bit diameter, and reinforcement steel plate 4 is welded between steel plate and rod iron；
Step 3：Rock drill is started shooting, and backfilling material is rammed with rock drill, is rammed and is stacked when ramming, and overlapping area is no less than 1/3,
Each tamping point is rammed no less than 6-8 and is hit, while ramming using the mechanical large arm of rock drill be downwardly applied to pressure for aid in rammer
Real, each tamping operation face is rammed no less than twice；
Step 4：Symmetrical backfill construction is carried out, one layer is rammed in structure both sides or the symmetrical back-filling in layers compacting of surrounding, backfill and finishes
Afterwards, compactness detection is carried out in time, and after meeting design requirement, record, which is rammed, hits number and pass；
Step 5：Above each layer backfill is rammed, and is operated by the pass of record, until design altitude is backfilled to, it is tight during ramming
Taboo rams plate touching underground structure.
Since the method for the present invention tamping energy derives from the pressure of mechanical large arm application, while rushing for rock drill has been superimposed again
It hits, heavy tamping energy is larger, and therefore, back-filling in layers thickness can increase to 500-600mm.
