Description

The novel building special-purpose borrow equipment of constructing

Technical field

The utility model relates to a kind of equipment of building foundation engineering, particularly relates to a kind of building operations borrow 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 applicant once applied for the Chinese utility model patent of building operations with borrow equipment for this reason, this device fetches earth totally, efficient is high, can reduce labour intensity, improve execution conditions and accelerating construction progress, but this apparatus structure complexity, and owing to the long-pending soil of inhaling between native passage and flexible pipe, the soil sucking head in junction causes stopping up especially easily.

The utility model content

The problem that the utility model exists at prior art and provide a kind of structure simpler, easy to operate, can not amass the building operations borrow equipment that soil fetches earth clean.

The utility model realizes that the purpose technical scheme is:

The novel building special-purpose borrow equipment of constructing, comprise containing to be provided with in soil bucket, the Sheng soil bucket and inhale native passage, inhaling native passage is fixed by three bracing frames, inhale and be connected with soil sucking head after native passage passes Sheng soil bucket bottom, the other end extends to staving top, negative pressure source is contained the soil suction in the soil bucket by inhaling native passage, and negative pressure source is connected with power supply by power line, and the soil-containing bucket cap spiral-lock is in containing on the native bucket.

Described Sheng soil bucket is horizontal.

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

The utility model compared with prior art owing to removed flexible pipe, has reduced the obstruction that the long-pending soil of junction causes.And, increased fastness because it is fixing by three bracing frames to inhale native passage.Inhale native speed through evidence 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 to be inhaled, wet inhale or two kinds of methods are alternately united and used all rightly in addition, is 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; 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, 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, contain the suction soil passage 6 that is provided with a rigid tubular in the soil bucket 3, the lower end is connected with soil sucking head 1 after passing 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, battery 7 is connected with negative pressure source 9, for negative pressure source 9 provides electric energy, battery 7 also is arranged in the soil-containing bucket cap 4.Negative pressure source 9 can also link to each other with power supply by the power line that is wrapped on iron chains or the wire rope simultaneously.Negative pressure source 9 also can link to each other with the inlet end of air compressor.

When the utility model uses, the borrow equipment of slinging is 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 soil sucking head 1, the native passage 6 of suction, the 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.Powered-down hangs out borrow equipment after the exhaustion, outwells a barrel interior inhalation (inhalatio), prepares operation next time.

Claims (2)

1, the novel building special-purpose borrow equipment of constructing, it is characterized in that comprising containing to be provided with in soil bucket (3), the Sheng soil bucket (3) and inhale native passage (6), inhaling native passage (6) is fixed by three bracing frames (8), inhale and be connected with soil sucking head (1) after native passage (6) passes Sheng soil bucket (3) bottom, the other end extends to staving top, negative pressure source (9) sucks soil in the Sheng soil bucket (3) by inhaling native passage (6), negative pressure source (9) is connected with power supply by power line (5), and soil-containing bucket cap (4) spiral-lock is in containing on the soil bucket (3).
