Abstract

The utility model relates to a soil-receiving device used in building construction, which is the preferred soil-borrowing device of a sunk pipe precast steel concrete pedestal pile, and can be used for borrowing the soil of other type piles. The soil-receiving device consists of a soil-collecting channel (6) and a negative pressure source (9) used for collecting and positioning the soil in a soil-filling barrel (3) on the ground. The soil-collecting channel (6) is fixed by three carriages (8), the negative pressure source (9) is connected with a reversible cell (7), and the negative pressure source (9) and the reversible cell (7) are arranged in a soil-filling barrel hat (4). Compared with the prior art, a soil-collecting head and a flexible pipe are removed, and only the soil-collecting channel, and the soil-filling barrel and the suction negative pressure source are arranged, thereby simplifying the structure and reducing the production cost, and a small amount of joints makes little blockage approved by the test. The soil-receiving device used in building construction 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, and saving labors and time; and dry adsorption and wet adsorption or the both methods can be alternately or jointly used with wide applicability.

Description

A kind of novel building construction soil collection device

Technical field

The utility model relates to a kind of equipment of building foundation engineering, and particularly a kind of building operations soil collection device that relates to 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 a kind of building operations with soil collection device for this reason, this device fetches earth totally, efficient is high, can reduce labour intensity, improve execution conditions and accelerating construction progress, but the junction of finding flexible pipe and soil sucking head in actual use and inhaling native passage is stopped up easily, is unfavorable for inhaling soil.

The utility model content

The problem that the utility model exists at prior art and provide a kind of structure simple more, inhale the building operations soil collection device of native better effects if.

The utility model realizes that the purpose technical scheme is:

A kind of novel building construction soil collection device, it is to be made of the negative pressure source of inhaling native passage and soil is sucked in the Sheng soil bucket that is arranged on ground, inhale native passage and fixed by three bracing frames, negative pressure source is connected with battery, and negative pressure source and battery are arranged in the soil-containing bucket cap.

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, only is provided with and inhales native passage, Sheng soil bucket and suction-type negative pressure source, simplifies the structure, and has reduced cost of production.And, be not easy to stop up because the junction is few.Because it is fixing by three bracing frames to inhale native passage, has increased fastness.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, 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, 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 negative pressure source 9 links to each other with power supply by power line, negative pressure source 9 can also be connected with battery 7, and battery 7 also is arranged in the soil-containing bucket cap 4.Negative pressure source 9 also can link to each other with the inlet end of air compressor.

When the utility model uses, the native passage 6 of suction is stretched out an end of containing soil bucket 3 put into immersed tube up to the bottom, when the end of starting working Sheng soil bucket 3 for last power supply negative pressure source 9 contacts hack, 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. a novel building is constructed and is used soil collection device, it is characterized in that it is to be made of the negative pressure source (9) of inhaling native passage (6) and soil is sucked in the Sheng soil bucket (3) that is arranged on ground, inhaling native passage (6) is fixed by three bracing frames (8), negative pressure source (9) is connected with battery (7), and negative pressure source (9) is arranged in the soil-containing bucket cap (4) with battery (7).
