Abstract
The utility model discloses a pass through impact stake machine tup on cobble layer fast, including the hammer block, the head of hammer block be provided with hammer point portion, the afterbody is provided with steady fin in the middle of. The utility model discloses simple structure increases the penetrating power of tup, stability when having increased the tup whereabouts.
Description
Technical Field
The utility model relates to a building engineering machinery specifically is a pass through impact stake machine tup on cobble layer fast.
Background
The pile foundation is a foundation form which is widely applied, and is widely applied to house construction, bridges and port engineering. Especially under complex geological conditions such as soft soil, sandy soil and the like, the pile foundation is almost an irreplaceable foundation form. With the continuous development of modern building engineering, the structural requirements of height, weight, bearing capacity and the like of a building are continuously improved. The depth of the foundation pile is also continuously deepened. The foundation pile will encounter more and more complex geological conditions in the process of extending downwards. Crossing the pebble layer is one of the great difficulties encountered in extending the foundation pile downwards.
The pile can be divided into two categories, namely a precast pile and a cast-in-place pile according to the construction method, wherein the precast pile is manufactured in a precast plant or on site before a pile body is put into a foundation. The cast-in-place pile is formed by drilling, punching, digging and the like directly at a specified position, and then concrete is cast in the hole.
Due to the characteristics of the sand pebbles, the obvious problems of slow footage, hole collapse, overlarge filling coefficient and the like during hole forming are determined.
The existing literature retrieval shows that the project has no simple and effective scheme for solving the problems, and only can increase the operation time and tolerate the loss caused by a huge filling coefficient.
SUMMERY OF THE UTILITY MODEL
The utility model provides a pass through impact stake machine tup on cobble layer fast, simple structure increases the penetrating power of tup, has increased the stability when tup whereabouts.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a strike stake machine tup that passes through cobble layer fast, includes the hammer block, the head of hammer block be provided with hammer tip portion, the afterbody is provided with steady fin in the middle.
Preferably, the stable tail wing is formed by vertically arranging four tail wing plates into a cross shape, and has a good stabilizing effect.
Preferably, the lower end of the stable tail wing is connected with the hammer body through the connecting column, so that the installation of the stable tail wing is convenient, and the stability of the hammer head can be improved.
As another preferred, the outer side edge of the stable tail wing is a bevel edge, which is beneficial to improving the stability of the hammer head.
Preferably, the taper of the hammer tip is 15-20 degrees, and the angle is reasonable.
Compared with the prior art, the beneficial effects of the utility model are that:
the original hammer is improved, the rigidity of the hammer is increased, and the top stress area is reduced, so that the stress form of the hammer is changed, the penetrating power of the hammer is increased, and meanwhile, the tail wing is added at the tail of the hammer, the stability of the hammer when falling is kept, and hole deviation is prevented; through on-site practical application, the average advancing speed is 1.5 times of that of the traditional hammer head, the average filling coefficient is basically controlled to be about 1.15, and the average filling coefficient of the traditional hammer head is 1.3-1.4 under the same condition, so that the economic effect is obvious.

fig. 2 is a schematic top view of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, the utility model provides a strike stake machine tup that passes through cobble layer fast, including hammer block 1, the head of hammer block 1 be provided with hammer point portion 4, the afterbody is provided with steady fin 3 between two parties.
According to the basic physics knowledge, the thinner the hammer, the lower the resistance. Therefore, the stress area of the hammer head is reduced. The resistance is reduced, and the hammer can enter the soil body more easily. Meanwhile, in order to ensure the stability and the precision of the slender hammer body in the falling process, when the hammer body is improved, four tail wings are arranged at the tail part and arranged in a cross shape, so that the stability of the hammer body is improved.
After the form of the hammer head is changed, the hammer head is broken when meeting pebbles, and meanwhile, partial gravels can be squeezed into the surrounding soil body, so that the compactness of the surrounding soil body is increased. Preventing collapse. And the filling coefficient of the concrete is reduced.
As an embodiment of the utility model, steady fin 3 vertically arrange into the cross by four tail pterygoid laminas and form, have better stable effect, the lower extreme of steady fin 3 link to each other with hammer block 1 through spliced pole 2, make things convenient for steady fin 3 to install, can improve the stationarity of tup moreover, wherein, the outside limit of steady fin 3 be the hypotenuse, be favorable to improving the stationarity of tup, the tapering of hammer point 4 be 15-20, this angle is more reasonable, the penetrating power is strong.
While the invention has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, as long as there is no structural conflict, the various features of the disclosed embodiments of the present invention can be used in any combination with each other, and the description of such combinations is not exhaustive in the present specification only for the sake of brevity and resource conservation. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
