Abstract
The utility model relates to the technical field of finishing of groove sections of an underground continuous wall, in particular to a novel square drilling hammer. Circular drilling hammers are arranged in parallel. Large steel plates and small steel plates are arranged at intervals and surround side surfaces of the circular drilling hammers. A cuboid structure is formed below the large steel plates and the small steel plates. Bottom edges of the large steel plates are provided with pointed claws in an outwardly-extending mode. The novel square drilling hammer is not easily stuck during groove trimming and has high efficiency of groove trimming.
Description
Technical field
The utility model relates to the groove section dressing technique field of diaphragm wall, is specifically related to a kind of Novel square and bores hammer.
Background technology
In the construction of diaphragm wall, first adopt gripping-type groover or percussive drill work to form groove section, but groove section can exist cell wall to have the wedge angle of local crowning or cell wall thickness not to reach the problems such as designing requirement.In order to address these problems, conventionally take to be welded with four road steel plates in the surrounding of circle brill hammer and form easy square diamond hammer, coordinate this square diamond hammer to repair groove section with percussive drill again, but hammer deadweight is less owing to boring, while repairing groove, easily block at the position of cell wall thickness deficiency, therefore repair groove efficiency lower.
Utility model content
For the defect existing in prior art, the purpose of this utility model is to provide a kind of Novel square to bore hammer, and it should not be stuck in the time repairing groove, and it is high to repair groove efficiency.
For reaching above object, the technical scheme that the utility model is taked is: a kind of Novel square bores hammer, comprise two circular hammer, two blocks of large steel plates and two blocks of little steel plates of boring, the described circular hammer that bores is set up in parallel, described large steel plate and little steel plate interval arrange and are surrounded on described circular side of boring hammer, the below of described large steel plate and little steel plate forms rectangular structure jointly, and the base of described large steel plate stretches out sharp pawl is set.
On the basis of technique scheme, described large steel plate and little steel plate and circular boring between hammer are connected and fixed by auxiliary steel plate.
On the basis of technique scheme, the thickness of described large steel plate and little steel plate is 65mm, and the thickness of described auxiliary steel plate is 30mm.
On the basis of technique scheme, described circular top of boring hammer arranges extension lifting hole(eyelet).
On the basis of technique scheme, described circular bottom of boring hammer is flower shape, and on every petal, is equipped with the hammer tooth of protrusion.
On the basis of technique scheme, described sharp pawl is welded on large steel plate.
The beneficial effects of the utility model are:
1, the utility model square diamond hammer is difficult for being stuck, and adopts two brill hammers to be arranged side by side and to be connected to form by steel plate, and the more former brill hammer of conducting oneself with dignity is difficult for while repairing groove being stuck more than improving twice.
2, to repair groove efficiency high for the utility model square diamond hammer, and the bottom of large steel plate is provided with sharp pawl, and cell wall boss is had to good finishing effect.
3, to repair groove quality high for the utility model square diamond hammer, and Novel square bores hammer from great, and impact force is large, is difficult for deflection occurs while repairing groove, higher to the dressing quality of groove section.
Brief description of the drawings
Fig. 1 is the front elevation drawing that this Novel square bores hammer.
Fig. 2 is the left view that this Novel square bores hammer.
Fig. 3 is the upward view that this Novel square bores hammer.
Reference numeral: the circular hammer 1 that bores, hang lifting hole(eyelet) 11, hammer tooth 12, large steel plate 2, little steel plate 3, rectangular structure 4, sharp pawl 5, auxiliary steel plate 6.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of Novel square bores hammer, comprise two circular hammer 1, two blocks of large steel plates 2 and two blocks of little steel plates 3 of boring, the described circular hammer 1 that bores is set up in parallel, described large steel plate 2 and little steel plate 3 intervals arrange and are surrounded on described circular side of boring hammer 1, the below of described large steel plate 2 and little steel plate 3 forms rectangular structure 4 jointly, and described large steel plate 2 and little steel plate 3 and circular boring between hammer 1 are connected and fixed by auxiliary steel plate 6, for keeping circular stability of boring hammer.In the present embodiment, the thickness of described large steel plate 2 and little steel plate 3 is 65mm, and the thickness of described auxiliary steel plate 6 is 30mm.The base of described large steel plate 2 stretches out and is welded with sharp pawl 5.At the weak geological stratification of intensity, as soil layer, severely-weathered sand layers etc., sharp pawl 5 can directly excise the position of cell wall projection, repaiies groove effect thereby reach; At the stronger geological stratification of intensity, as gentle breeze sand layers etc., sharp pawl 5 can be by repeated stock the rock with broken projection, and less to the disturbance of cell wall, meet when repairing groove effect and can prevent landslip of the sides of the trench.Described circular top of boring hammer 1 arranges and hangs lifting hole(eyelet) 11, described circular bottom of boring hammer 1 is flower shape, and on every petal, be equipped with the hammer tooth 12 of protrusion, for broken rock, described hammer tooth 12 is consumable accessorys, activity is assemblied in the circular hammer 1 that bores, and is convenient for changing, thereby extends the whole service life that this square diamond is hammered into shape.
In the groove section build process of diaphragm wall, adopt percussive drill boring to form groove section to be trimmed, after having holed, adopt percussive drill to promote this square diamond hammer trim slots section, little stroke impacts the groove section between adjacent two borings, and the hammer tooth 12 of this square diamond hammer bottom is for smooth bottom land, and sharp pawl 5 is for removing the wedge angle of cell wall projection, thereby the planeness that ensures cell wall meets the requirement of specification and design, form groove section and be used for building diaphragm wall.
The utility model is not only confined to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a utility model or akin technical scheme, all within its protection domain.
