Abstract

The utility model relates to a soil-receiving device, which comprises a soil-filling barrel (3); a soil-collecting channel (6) is arranged in the soil-filling barrel (3), the soil-collecting channel (6) is fixed by three carriages (8), a negative pressure source (9) is used for collecting the soil into the soil-filling barrel (3) through the soil-collecting channel (6), the negative pressure source (9) is connected with a reversible cell (7), the negative pressure source (9) and the reversible cell (7) are arranged in a soil-filling barrel hat (4), the bottom end of the soil-collecting channel (6) passes through the soil-filling barrel (3), while the other end extends to the upper part of the barrel body, and the soil-filling barrel hat (4) is buckled on the soil-filling barrel (3). Compared with the prior art, a soil-collecting head and a flexible pipe are removed, thereby reducing the blockage due to the accumulated soil at joints; approved by the test, the soil-receiving device provided by the utility model has the advantages of collecting the soil fast, cleanly and thoroughly, obviously increasing the construction efficiency, being able to match with other procedures, quickening the construction speed, as well as saving labors and time; and dry adsorption and wet adsorption or the both methods can be alternately or jointly used with wide applicability.

Description

Novel borrow equipment

Technical field

The utility model relates to a kind of equipment of building foundation engineering, particularly relates to a kind of 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 regrettably for order better solution not arranged as yet up till now, 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 utility model patent of borrow equipment for this reason, but found this device structure complexity in practice, and flexible pipe and soil sucking head and the long-pending soil of inhaling the junction between the native passage stop up easily.

The utility model content

The problem that the utility model exists at prior art and provide that a kind of structure is simpler, easy to operate, clean borrow equipment fetches earth.

The utility model realizes that the purpose technical scheme is:

Novel borrow equipment, be provided with to inhale and contain the soil bucket, contain to be provided with in the soil bucket and inhale native passage, inhale native passage and fix by three bracing frames, negative pressure source sucks soil in the Sheng soil bucket by inhaling native passage, and negative pressure source is connected with battery, negative pressure source and battery are arranged in the soil-containing bucket cap, inhale the bottom of native passage and pass Sheng soil bucket, the other end extends to staving top, and the soil-containing bucket cap spiral-lock is in containing on native barrel.

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 because the obstruction that the long-pending soil of junction causes.And, increased fastness because the native passage of suction is fixed 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; 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 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, and the powerful negative pressure source of being located in the soil-containing bucket cap 49 has the structure similar to vacuum cleaner, and 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 5 that is wrapped on iron chains or the wire rope simultaneously.

When the utility model uses, the borrow equipment of slinging is 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 rapidly will near the soil body be inhaled into and contains in the soil barrels 3 by inhaling native passage 6, and equipment begins to promote repeatedly decline, be accompanied by and do 360 degree rotations back and forth, 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.Powered-down hangs out borrow equipment after the exhaustion, outwells a barrel interior inhalation (inhalatio), prepares operation next time.

Claims

1. novel borrow equipment, it is characterized in that being provided with Sheng 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) by inhaling native passage (6), negative pressure source (9) is connected with battery (7), negative pressure source (9) is arranged in the soil-containing bucket cap (4) with battery (7), inhale the bottom of native passage (6) and pass Sheng soil bucket (3), the other end extends to staving top, and soil-containing bucket cap (4) spiral-lock is in containing on the soil bucket (3).
