Abstract

The utility model discloses an equipment for the substructure of construction, in particular to an earth absorption device. The device consists of an earth absorber (1), a soft tube (2), and a negative power supply (9) inside an earth barrel (3). The earth is taken to the earth barrel (3) on the ground through the earth absorber (1) and the soft tube (2). The negative power supply (9) is connected with a power via a power lead (5). The earth barrel (3) is vertical in shape. The absorption end of the earth absorber (1) may be any one of rigid round, normal bend, in-line, or flatness. The utility model, compared with prior art, is proved to be fast, clean, and complete at absorbing the earth since a series of technical measures are adopted such as the earth absorber, the soft tube, the earth barrel, and the absorptive negative power supply, thus obviously raising the execution efficiency. The device may be matched with other working procedures so as to facilitate the execution progress as well as save labor and time. Otherwise, the utility model may take dry absorption, moisture absorption, or work alternatively with these two methods. Therefore, the utility model is of wide range for application.

Description

Inhale 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 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 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, reduces labour intensity, improves the suction indigenous equipment that is used for pipe sinking prefabricated steel concrete club-footed pile of execution conditions and accelerating construction progress.

The utility model realizes that the purpose technical scheme is:

Inhale indigenous equipment, it is to be made of soil sucking head, flexible pipe and the negative pressure source that soil sucked in the Sheng soil bucket that is arranged on ground by soil sucking head, flexible pipe, and negative pressure source is connected with power supply by power line, and it is vertical containing native barrel.

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

The utility model compared with prior art, owing to adopted a series of technical measures such as soil sucking head, flexible pipe, Sheng soil bucket and suction-type negative pressure source and had the native speed of suction totally thoroughly, obviously to improve efficiency of construction soon through evidence, and can be complementary with other operation, accelerating construction progress, when the saving of labor saves, do to inhale in addition, 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 1, soil sucking head; 2, flexible pipe; 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 end that Sheng soil bucket 3 is passed in the lower end, link to each other with the upper end of flexible pipe 2, the lower end of flexible pipe 2 links to each other with soil sucking head 1, inhale native passage 6 upper ends and extend to the top of containing soil bucket 3, and fixed with at least one bracing frame 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, and 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.Flexible pipe 2 is located at above ground portion has one section to be stereoplasm tube, and the operator holds during convenient work.

The suction side of described soil sucking head 1 is any one in rigid circular, elbow bend, in-line and the flat; Flexible pipe 2 be in flexible metal conduit and the bellows any one; Negative pressure source 9 also can link to each other with the inlet end of air compressor.

When the utility model uses, flexible pipe 2 and soil sucking head 1 are put into immersed tube up to the bottom, when starting working soil sucking head 1 contact hack for last power supply negative pressure source 9, powerful air-flow is inhaled near the soil body rapidly and contains in the soil bucket 3 by flexible pipe 2, the native passage 6 of suction, 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, inhales indigenous equipment, it is characterized in that it is to be made of soil sucking head (1), flexible pipe (2) and the negative pressure source (9) that soil sucked in the Sheng soil bucket (3) that is arranged on ground by soil sucking head (1), flexible pipe (2), negative pressure source (9) is connected with power supply by power line (5), and it is vertical containing soil bucket (3).
