Abstract
The utility model relates to a tool for tamping, in particular to a quartering hammer type tamping device which solves the problems that labor intensity is high, construction process is slow, work efficiency is low and the vibration to human bodies is large when backfill tamping construction is conducted by adopting a frog hammer and a vibratory impulse tamping machine. The quartering hammer type tamping device comprises a quartering hammer and a steel tamping plate, wherein a locating hole is formed in the middle of the steel tamping plate, a drill rod of the quartering hammer is inserted into the locating hole, one end of the drill rod of the quartering hammer is fixedly arranged inside the locating hole of the steel tamping plate, the other end of the drill rod of the quartering hammer is connected with the quartering hammer, and reinforcing steel bars are welded around the steel tamping plate. Efficiency is high, constructors are few, structure is simple, manufacturing cost is low, operation is easy, construction quality can be guaranteed, and thus certain popularization value and use value are achieved.
Description
Technical field
The utility model relates to a kind of ramming instrument, is specially a kind of broken hammer roller-compactor.
Background technology
Often can use rammer in the construction of construction work backfill, can only tamp with small-sized rammer after the position backfill that foundation trench backfill or other are limited by site condition, small-sized rammer commonly used has breast-stroke, vibratory impulse tamping machine etc., if tamp with frog hammer or vibratory impulse tamping machine, the one, carry out repeatedly manual zoning's compacting, the method labour intensity is high, construction speed is slow, inefficiency; The 2nd, above-mentioned two kinds of rammers vibrations are larger, and the workman can cause uncomfortable because of long-time operation machinery.
Summary of the invention
The utility model is existing when adopting frog hammer, vibratory impulse type rammer to carry out backfill compacting construction in order to solve, have that labour intensity is high, construction speed slow, inefficiency, the problem large to human body vibration, a kind of broken hammer roller-compactor is provided.
The utility model is to adopt following technical scheme to realize: broken hammer roller-compactor, comprise the quartering hammer, the steel compacting plate that are installed on the excavator, offer locating hole in the middle of the steel compacting plate, plug crushing hammar drill rod in the locating hole, crushing hammar drill rod one end is fixed in the locating hole of steel compacting plate, and the other end is connected with quartering hammer.
Be welded with stiffener around the described steel compacting plate, play the effect of reinforcing steel compacting plate.
Adopt structure design of the present utility model, weld crushing hammar drill rod in the locating hole in the middle of steel compacting plate, thereby form " compacting plate ", then " compacting plate " is installed on the hydraulic crawler excavator, just can carry out the backfill compacting.The utility model instrument is compared with HCR80 type vibratory impulse rammer, and efficient is high, the constructor is few, and simple in structure, cost of manufacture low (about 100 yuan of all material and manufacturing cost), simple to operate, and can guarantee construction quality, have certain promotional value and use value.Concrete contrast situation is as follows:
HCR80 type vibratory impulse rammer tamping plate is of a size of 300 * 310mm, pace is 8-12m/min, 100 meters long, 0.8 meter wide, 1.0 meters dark grooves are carried out backfilling compaction, definite through testing, needing to divide four layers tamps, will tamp 2 times for every layer, compactness just can meet design requirement, and will divide 3 compactings in the width range.Every rammer is wanted three workman's coordinative constructions, and finishing this work probably needs 3-5 hour;
Roller-compactor described in the utility model, its steel compacting board size is 400 * 400mm, consider the Mechanical Moving time, compacting speed is 5m/min, definite through testing, this work only tamped needs minutes two layers to carry out, every layer of compacting 1 time, compactness can meet design requirement, and carries out the secondary compacting in the width range and gets final product.A repacking rammer needs a mini-excavator coordinative construction, and finishing this work probably needs 1.3 hours.
Description of drawings
Fig. 1 is perspective view of the present utility model;
Fig. 2 is lateral view of the present utility model;
Among the figure: 1-steel compacting plate; The 2-locating hole; The 3-crushing hammar drill rod; The 4-stiffener.
The specific embodiment
Broken hammer roller-compactor, as shown in Figure 1, 2, comprise the quartering hammer, the steel compacting plate 1 that are installed on the excavator, offer locating hole 2 in the middle of the steel compacting plate, plug crushing hammar drill rod 3 in the locating hole, crushing hammar drill rod 3 one ends are fixed in the locating hole 2 of steel compacting plate 1, and the other end is connected with quartering hammer.Be welded with stiffener 4 around the steel compacting plate 1.According to actual needs also through test of many times, the long 40cm of steel compacting edges of boards, thick 3cm, and the periphery that will be welded on the stiffener of 25mm steel compacting plate is strengthened, guarantee steel compacting plate is indeformable in a long time, and (mechanical model is different, the impact force size is also different, required " compacting plate " length of side, thickness, strengthening measure can be not identical yet, so want concrete condition specifically to treat).
During concrete the making, the steel plate that 30mm is thick is made into the steel compacting plate of 400*400mm size; In the middle of steel compacting plate, drive locating hole (aperture is slightly larger than the crushing hammar drill rod diameter); Reinforcing bar and steel compacting plate firm welding with diameter 25mm; Crushing hammar drill rod penetrates in the steel compacting plate locating hole and firm welding with it; Steel is tamped plate to be installed on the quartering hammer (excavator) and to tamp construction.Should note following problem when carrying out the backfilling compaction construction with the method:
To there be the special messenger to command when 1, compacting is constructed, in order to avoid will destroy with complete engineering;
2, the commanding will observe the situation with complete engineering at any time, avoids that impact force is excessive, same point is rammed overlong time and caused with complete engineering destroyed;
3, different because of machinery, impact force is different, so lift height wants site inspection, test to determine, in order to avoid the blocked up compacting compactness of layering does not meet excessively thin causing damage of designing requirement or layering;
4, in machinery when walking above project completed, will be taked reliable safeguard measure (such as this engineering construction time carry out the piecemeal compacting, backfilling compaction fills up the soil protection, and then advances to grade beam, when the brick wall surface is concordant at grade beam, above the brick wall).
