Abstract

The utility model relates to an earth receiving device of prefabricated reinforces enlarged toe piles, which comprises an earth containing barrel (3) which is in horizontal type, an earth absorbing passage (6) is arranged in the earth containing barrel (3) and three supporting frames (8) are used for fixing the earth absorbing passage (6). Earth is absorbed into the earth containing barrel (3) which is arranged on the ground by a negative pressure source (9) through the earth absorbing passage (6). The negative pressure source (9) is connected with an electrical source by power cords (5). The absorbing end of the earth absorbing passage (6) is in the shape of flat section. Compared with the prior art, the utility model reduces many connecting parts and effectively prevents sedentary earth from jamming in the connecting part due to getting rid of an earth absorbing head and a flexible tube. After proving by experiment, the utility model has the advantages that the earth is absorbed rapidly, cleanly and completely, the construction efficiency is improved obviously, the construction schedule is quickened by matching with other working procedures, the labor and the time are saved, and the dry absorption and the wet absorption are combined to use or the two ways are used alternatively, and the application range is wide.

Description

The receipts indigenous equipment of novel precast reinforced concrete pile

Technical field

The utility model relates to the receipts indigenous equipment of a kind of equipment of building foundation engineering, particularly a kind of precast reinforced concrete pile, is the borrow equipment that immersed tube prefabricated steel concrete expands end first-selection, also can be used for fetching earth of other type stake.

Background technology

Along with the fast development of builing industry, especially the high building of each big and medium-sized cities stands in great numbers, and is seen everywhere and becomes one beautiful view in city, place and landmark building.Well-known these grand magnificent piles are to lean on the Foundation Design of more stable and stronger to support, thereby visible Foundation Design quality is good with bad, quality to building plays crucial effects, each unit in charge of construction especially pays attention to the quality of Foundation Design when paying attention to the superstructure quality for these reasons, expands the Foundation Design at the end for the supporting capacity that improves single pile generally adopts immersed tube prefabricated steel concrete in recent years.After the immersed tube that will have the prefabricated metal pile crown during construction is pressed into the hardpan of design elevation, take out metal pile head, bottom-expanding equipment with expanded bore pile is lowered to immersed tube location back start formation expansion base cavity pocket again, and the soil body pulverized, hang out bottom-expanding equipment, then be that people with waist tether rope is lowered to tens meters dark immersed tube bottom cleanings and expands diffusing soil in the end cavity, because narrow space, put to good use not open, the very low single pile cleaning task of fetching earth of generally finishing of operating efficiency got 24-30 hour, it is consuming time to take a lot of work, and has become the bottleneck operation of Foundation Design, has a strong impact on programming, cause the concern of some related scientific research units already, can up to the present better solution not arranged as yet regrettably, unit in charge of construction has no way out day by day, and adhering to old ways year after year constructed so far.The applicant once applied for the Chinese utility model patent of the receipts indigenous equipment of precast reinforced concrete pile for this reason, and this equipment fetches earth totally, but found this equipment in practice owing to exist too much junction, the long-pending soil of junction to cause easily stopping up.

The utility model content

The problem that the utility model exists at prior art and provide a kind of simple in structure, easy to operate, fetch earth clean, efficient is high, the not susceptible to plugging receipts indigenous equipment that is used for pipe sinking prefabricated steel concrete club-footed pile.

The utility model realizes that the purpose technical scheme is:

The receipts indigenous equipment of novel precast reinforced concrete pile, comprise and contain the soil bucket, it is horizontal containing the soil bucket, contain to be provided with in the soil bucket and inhale native passage, inhaling native passage fixes by three bracing frames, negative pressure source sucks soil in the Sheng soil bucket that is arranged on ground by inhaling native passage, and negative pressure source is connected with power supply by power line, and the suction side of inhaling native passage is a flat.

Advantage of the present utility model and effect are as follows:

The utility model compared with prior art owing to removed soil sucking head and flexible pipe, has reduced a lot of junctions, has effectively controlled because the obstruction that the long-pending soil of junction causes.And inhale native passage and fix, increased fastness by three bracing frames.Have through evidence and to inhale native speed and totally thoroughly, obviously improve efficiency of construction soon, and can be complementary with other operation, accelerating construction progress, when the saving of labor saves, do in addition inhale, wet inhale or two kinds of methods are alternately united and used all rightly, be applied widely.

Description of drawings

Fig. 1 is the utility model master TV structure schematic diagram.

Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.

Among the figure 3, contain the soil bucket; 4, soil-containing bucket cap; 5, power line; 6, inhale native passage; 7, battery; 8, bracing frame; 9, negative pressure source.

The specific embodiment

Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings, but protection domain of the present utility model is not limit by embodiment.

The utility model master TV structure schematic diagram as shown in Figure 1, its structure is as follows:

Containing soil bucket 3 is through the welding processing moulding by steel plate, for making them under normal conditions can all hacks that are absorbed into from base of splendid attire, do the volume of containing the staving of soil bucket 3 enough big, it is horizontal containing and being arranged on ground for native barrel 3, contain the suction soil passage 6 that is provided with a rigid tubular in the soil bucket 3, the lower end of inhaling native passage 6 is a flat, pass the bottom of containing soil bucket 3, inhale native passage 6 upper ends and extend to the top of containing soil bucket 3, and fixed with three bracing frames 8, fall into smoothly in the Sheng soil bucket 3 for ease of the hack that sucks, inhale the upper end of native passage 6 and make the elbow shape, soil-containing bucket cap 4 spiral-locks are in the upper end of containing soil bucket 3 and keep airtight, the powerful negative pressure source of being located in the soil-containing bucket cap 49 has the structure similar to vacuum cleaner, negative pressure source 9 links to each other with power supply by power line 5, and negative pressure source 9 can also be connected with battery 7, and battery 7 also is arranged in the soil-containing bucket cap 4.

When the utility model uses, immersed tube is put into up to the bottom in the suction side of inhaling native passage 6, when starting working for last power supply negative pressure source 9 to inhale native passage 6 contact hacks, powerful air-flow is inhaled near the soil body in the Sheng soil bucket 3 by inhaling native passage 6 rapidly, use the rear base hack will be blotted only, for the very big base of base diameter, after sopping up most of soil body, water filling in the immersed tube sopped up mud then in the past.The inhalation (inhalatio)s that powered-down will be provided with in the Sheng soil bucket 3 on ground again after the exhaustion are outwelled, and prepare operation next time.

Claims (1)

1. the receipts indigenous equipment of novel precast reinforced concrete pile, it is characterized in that comprising Sheng soil bucket (3), it is horizontal containing soil bucket (3), contain to be provided with in the soil bucket (3) and inhale native passage (6), inhaling native passage (6) fixes by three bracing frames (8), negative pressure source (9) sucks soil in the Sheng soil bucket (3) that is arranged on ground by inhaling native passage (6), and negative pressure source (9) is connected with power supply by power line (5), and the suction side of inhaling native passage (6) is a flat.
