Description

Novel architecture is inhaled indigenous equipment

Technical field

The utility model relates to a kind of equipment of building foundation engineering, and particularly a kind of suction indigenous equipment for building 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.For this reason, the applicant once applied for the Chinese utility model patent of suction indigenous equipment for building, this equipment fetches earth totally, efficient is high, but finds this equipment in practice because at soil sucking head with inhale and have too much junction between native passage and the flexible pipe, the long-pending soil of junction causes stopping up easily.

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, not susceptible to plugging suction indigenous equipment for building.

The utility model realizes that the purpose technical scheme is:

Novel architecture is inhaled indigenous equipment, it comprises the negative pressure source in the Sheng soil bucket of containing the soil bucket and the soil suction being arranged on ground, negative pressure source is connected with power supply by power line, contain to be provided with in the soil bucket and inhale native passage, inhale native passage and fix by three bracing frames, an end of inhaling native passage passes contains the soil bucket, and the other end extends to staving top, the soil-containing bucket cap spiral-lock is in containing on the soil bucket, and it is vertical containing the soil bucket.

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 the junction, has effectively prevented because the long-pending obstruction made from local methods of junction.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; 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 vertical 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 bottom of containing soil bucket 3 is passed in the lower end, 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, and negative pressure source 9 links to each other with power supply by power line 5.

When the utility model uses, to inhale native passage 6 and put into immersed tube up to the bottom, 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, novel architecture is inhaled indigenous equipment, it is characterized in that it comprises contains soil bucket (3) and soil is sucked negative pressure source (9) in the Sheng soil bucket (3) that is arranged on ground, negative pressure source (9) is connected with power supply by power line (5), contain to be provided with in the soil bucket (3) and inhale native passage (6), inhale native passage (6) and fix by three bracing frames (8), an end of inhaling native passage (6) passes contains soil bucket (3), and the other end extends to staving top, soil-containing bucket cap (4) spiral-lock is in containing on the soil bucket (3), and it is vertical containing soil bucket (3).
