Description
Technical Field
The utility model belongs to the technical field of side slope protection engineering construction, concretely relates to device is squeezed into to air pick of directly beating income formula reinforced soil nail.
Background
In the slope protection project of the soft soil stratum, a reinforced soil nail is directly driven in the construction, and the method generally adopts a manual hammering method, a hydraulic hammer method and a hand-held vibration hammer method. The first manual hammering method has poor driving effect, low construction efficiency and high construction period cost, and is rarely adopted at present; in the second hydraulic hammer method, the hammering force is not easy to control, the reinforced soil nails are easy to deform and scrap, and operators are easy to be injured due to improper operation; in a third method of holding the vibratory hammer, for example, an air pick, the problem that the air pick and the reinforced soil nail are difficult to align and the transmission of the impact force is not easy to control is solved.
Disclosure of Invention
Based on the circumstances, the utility model discloses based on above-mentioned third method, study the improvement to the problem that meets in the pneumatic pick operation, aim at provides the pneumatic pick of the direct formula of beating into reinforcing bar soil nail and squeezes into the device, solves the problem that the impact force effectively transmitted between pneumatic pick and the reinforcing bar soil nail simple and practical.
In order to realize the purpose, the utility model discloses a technical scheme is:
the pneumatic pick driving device for directly driving in the reinforced soil nail comprises a connecting steel plate, wherein two ends of the connecting steel plate are respectively welded with a steel pipe, the reinforced soil nail is inserted into the steel pipe at one end, and the pneumatic pick with a flat head upsetting pick is inserted into the steel pipe at the other end.
The steel pipe should be according to the diameter flexible selection of reinforced bar soil nail and flat head upset pick, should guarantee 2 ~ 3 mm's headroom after emboliaing.
The size of the connecting steel plate is 5-10 mm larger than the outer wall of the steel pipe, and the connecting steel plate is preferably processed by adopting a steel plate with the thickness of more than 2 cm.
The length of the steel pipe is determined according to the exposed lengths of the flat head upsetting pick and the reinforced soil nail, the length of the steel pipe at one end is not more than the length of the flat head upsetting pick, and the length of the steel pipe at the other end is not more than the exposed length of the reinforced soil nail.
The flat head upsetting pick head is formed by cutting off a sharp head and upsetting of a common air pick head.
The utility model has the advantages that:
the structure has the advantages of simple structure, convenient operation and low cost. All parts of the device can be machined and transformed on the site aiming at the reinforced soil nails with different diameters according to actual conditions, and the device has strong adaptability. The operation is convenient and fast, and the operation method can be mastered without professional education and training. Meanwhile, due to the low cost, equipment and personnel are convenient to increase, so that the construction progress is improved.
Drawings
FIG. 1 is a schematic view of the device of the present invention
Wherein 1 is an air pick, 2 is a flat head upsetting pick, 3 is a steel pipe, 4 is a connecting steel plate, 5 is a reinforced soil nail, and 6 is a slope surface.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1, the pneumatic pick driving device for directly driving in the reinforced soil nail comprises a connecting steel plate 4 and is characterized in that two ends of the connecting steel plate 4 are respectively welded with a steel pipe 3, the reinforced soil nail 5 is inserted into the steel pipe 3 at one end, and the pneumatic pick 1 with a flat head upsetting pick head 2 is inserted into the steel pipe 3 at the other end, so that the impact force of the pneumatic pick 1 is more stably and effectively transmitted to the reinforced soil nail 5.
The steel pipe 3 is flexibly selected according to the diameters of the reinforced soil nail and the flat head upsetting pick 2, and a clearance of 2-3 mm is guaranteed after the steel pipe is sleeved in the steel pipe.
The size of the connecting steel plate 4 is larger than 5-10 mm of the outer wall of the steel pipe 3, welding is convenient to carry out on the outside, the connecting steel plate 4 is suitable for being processed by steel plates with the thickness of more than 2cm, and the fact that the connecting steel plate can bear impact force is guaranteed.
The length of the steel pipe 3 is determined according to the exposed lengths of the flat heading upsetting pickaxe 2 and the reinforced soil nail. The length of the steel pipe 3 at one end is not more than that of the flat head upsetting pick 2, and the length of the steel pipe 3 at the other end is not more than the exposed length of the reinforced soil nail.
The flat head upsetting pick 2 is formed by cutting off a sharp head of a common air pick and upsetting.
The utility model discloses a theory of operation.
The operation steps are as follows:
(1) the reinforced soil nails 5 are driven into the slope surface of the side slope at 6 point positions;
(2) sleeving a steel pipe 3 at one end of a connecting steel plate 4 into the end of a reinforced soil nail 6;
(3) a flat head upsetting pick head 2 of the air pick 1 extends into a steel pipe 3 at the other end of the connecting steel plate 4;
(4) the pneumatic pick 1 is started to feed the reinforced soil nails 5 into the soil body.
