In above-mentioned tumping rummer, above-mentioned exhaustion plate end face is fixed with bar, and this bar extends to along the steam vent in the hammer body in the chamber that is arranged in the hammer body, and the top of this bar is fixed with catch, be provided with compression spring between the surface in this catch and above-mentioned chamber, this spring encapsulation is on this bar.
In above-mentioned tumping rummer, it comprises the parts of ramming that are positioned at the bottom, this end face of ramming parts is along being vertically fixed with the positioning and fixing bar, near this ram parts above be stacked with the removable hammer piece of ramming, this is rammed in the hammer piece and offers through hole, by this through hole, this is rammed the hammer piece and is placed on the above-mentioned positioning and fixing bar, is stacked with standard hammer piece on this rams the hammer piece, offers through hole in this standard hammer piece, by this through hole, this standard hammer piece is placed on the above-mentioned positioning and fixing bar.
In above-mentioned tumping rummer, it is stacked with a plurality of standard hammer pieces above-mentioned ramming along the vertical direction above hammer piece, and these hammer pieces are all offered through hole, and by this through hole, these standard hammer pieces are placed on the above-mentioned positioning and fixing bar.
In above-mentioned tumping rummer, the external surface of above-mentioned positioning and fixing bar offers screw thread, is fixed with the nut of twisting on this positioning and fixing bar on the standard hammer piece at top.
In above-mentioned tumping rummer, above-mentioned exhaust passage is formed at the inside of above-mentioned positioning and fixing bar, offer groove in the above-mentioned bottom of ramming parts, one end of above-mentioned exhaust passage is communicated with this groove, the other end of this exhaust passage is communicated with the exhaust opening that is arranged at above-mentioned positioning and fixing masthead end, above-mentioned exhaustion plate embeds in the above-mentioned groove of ramming in the parts, between the end face of this plate and the above-mentioned groove floor compression spring is set.
In above-mentioned tumping rummer, it is for ramming the hammer of usefulness to cast-in-place concrete pile end ground stabilization material.
In above-mentioned tumping rummer, its for the filler in the compaction pile hole is rammed so that form the hammer of ramming that compaction pile uses.
The advantage of the tumping rummer that bore forming of the present utility model is used is that this tumping rummer inside is formed with the exhaust passage that is communicated with atmosphere, the bottom of this exhaust passage is communicated with the hammer bottom, when hammer is mentioned, exhaustion plate ejects downwards under pressure, thereby the hammer bottom space is communicated with atmosphere, can't form vacuum state, can avoid like this foundation soil body is picked up, produce the unfavorable phenomenon of stake hole undergauge.
With reference to the accompanying drawings, the tumping rummer of bore forming of the present utility model being used by the mode of embodiment specifically describes.
The elevational schematic view of the tumping rummer that Fig. 1 uses for bore forming of the present utility model;
Fig. 2 is the enlarged diagram of ramming parts in the tumping rummer shown in Figure 1.
As shown in Figure 1, the tumping rummer of using as the bore forming of an embodiment of the present utility model comprises rams parts 4, it is taper, promptly up big and down small, become overall fixed that positioning and fixing bar 3 is arranged at this central part of ramming the end face of parts 4, it extends along vertical, this bar 3 is a hollow stem, have exhaust passage 8 in it, this is rammed to be stacked with above the parts 4 and rams hammer piece 1, offer through hole in the middle of it, thereby it is set on the above-mentioned positioning and fixing bar 3, hammers piece 2a into shape along being stacked with a plurality of standards up and down on ram hammer piece 1,2b, 2c, 2d, 2e, the pars intermedia of these standard hammer pieces equally also offers through hole, thereby these standard hammer pieces are set on the above-mentioned positioning and fixing bar 3, and folded putting down together, the external surface of above-mentioned positioning and fixing bar 3 is threaded, like this by nut 6 being tightened against the top of above-mentioned positioning and fixing bar 3, just above-mentioned parts can be fixed together, and assembling forms tumping rummer.As shown in Figure 2, the above-mentioned bottom of ramming parts 4 offers groove 9, is provided with exhaustion plate 5 in it, is fixed with compression spring 10 between the bottom surface of the end face of exhaustion plate 5 and groove 9.The bottom of the exhaust passage 8 in the above-mentioned positioning and fixing bar 3 is communicated with above-mentioned groove 9, and its top is communicated with the exhaust opening 7 at positioning and fixing bar 3 tops.
Be provided with spring 10 and exhaustion plate 5 owing to ram the bottom of parts 4, be provided with the exhaust passage 8 that is communicated with groove 9 in addition in the positioning and fixing bar 3, like this in the process of carrying out impact holing, when mentioning tumping rummer, exhaustion plate 5 extrudes downwards under the elastic force effect of spring 10, thereby make the tumping rummer bottom surface keep being communicated with, and (vacuum) state that do not form negative pressure can avoid putting forward the undergauge phenomenon that causes when hammering into shape like this with atmosphere.
During fabrication, can only make ramming of a plurality of different-diameters and hammer piece 1 into shape, just can satisfy the construction requirement in piles with different footpath, thereby can obtain the tumping rummer of different-diameter by only changing the mode of fewer parts (ramming the hammer piece).In addition, also can the change standard quantity of hammer piece, the weight of tumping rummer is changed, so that increase or reduce the impact energy of ramming the ground stabilization material.
