Description

Tubular pile precipitation device

Technical Field

The utility model relates to a precipitation engineering field in the geotechnical engineering field.

Background

The prefabricated pipe piles are popularized all over the country in nearly two decades, the application amount is very large, and a large number of building projects and municipal projects use the pipe piles as anti-pulling or anti-compression bearing structures. The pipe piles are built along with a large amount of underground engineering. In the process of underground engineering construction, precipitation is a problem which needs to be faced by underground engineering construction at places with high underground water level. The tubular pile is characterized in that the tubular pile is of a hollow structure, the elevation of the pile top of the tubular pile is generally positioned at the position of a foundation bottom plate, and the depth of the tubular pile into the ground is generally larger than the depth of a dewatering well of underground engineering. The interval of tubular pile is generally less than the interval of precipitation tube well far away, if can utilize the tubular pile to carry out precipitation, will not need the construction of a large amount of precipitation wells, practices thrift the cost and the time limit for a project of precipitation engineering by a wide margin.

Disclosure of Invention

The utility model aims at providing a tubular pile precipitation device, this tubular pile precipitation device can accomplish precipitation device's construction in the tubular pile construction, has reduced precipitation well's cost by a wide margin, and the quality is reliable, and the cost is low, and the construction is convenient fast.

This tubular pile precipitation device includes tubular pile, groundwater collector, outlet pipe, precipitation power device four bibliographic categories branch, and wherein the tubular pile is buried in the hollow engineering stake in the underground deeply, and groundwater collector buries in the soil body, and groundwater collector includes rivers passageway and filter membrane two parts, and the rivers passageway wherein is connected with the hollow position of tubular pile, and the filter membrane parcel is in the outside of rivers passageway, and the outlet pipe is connected with the hollow position of tubular pile, and precipitation power device is the device of getting rid of the ponding that flows into tubular pile hollow position.

In the above-mentioned tubular pile precipitation device, the precipitation power device may be a combination of an air pipe connected to the hollow portion of the tubular pile and an air transmission device.

In the tubular pile precipitation device, a one-way valve for preventing accumulated water or air in the tubular pile from flowing back to the soil can be arranged at the water flow channel or in the tubular pile.

The utility model discloses a tubular pile precipitation device utilizes the tubular pile as the interim storage container of groundwater, accomplishes precipitation device's construction in the tubular pile construction. The construction cost is low, and is fast, and precipitation ability is strong, and the equipment maintenance cost is low, and the operation process safety of drawing water.

Detailed Description

As an embodiment of the present invention, the mechanism and the implementation method of the pipe pile precipitation device of the present invention are described in detail with reference to fig. 1. Firstly, the structure and the working mechanism of the pipe pile precipitation device are described with reference to fig. 1. As shown in fig. 1, the utility model discloses a tubular pile precipitation device includes tubular pile (1), groundwater collector (2), outlet pipe (3), precipitation power device (4) four bibliographic categories branch, tubular pile (1) wherein is buried in the hollow engineering stake in the underground deeply, groundwater collector (2) are buried in the soil body, groundwater collector (2) include rivers passageway (5) and filter membrane (6) two parts, rivers passageway (5) wherein are connected with the cavity position of tubular pile (1), filter membrane (6) parcel is in the outside of rivers passageway (5), outlet pipe (3) are connected with the cavity position of tubular pile (1), precipitation power device (4) are the device of getting rid of the ponding that will flow in tubular pile (1) cavity position. In the embodiment, the underground water flows into the hollow part of the pipe pile (1) through the filter membrane (6) and the water flow channel (5) and is discharged by the precipitation power device (4). The precipitation power device (4) can be a water pump arranged in the hollow part of the tubular pile (1) or a vacuum pump arranged on the ground and connected with the hollow part of the tubular pile (1). In the embodiment, the precipitation power device (4) can also be a combination of a gas pipe (7) connected with the hollow part of the tubular pile (1) and a gas transmission device (8), and in this case, precipitation is completed according to the following mechanism. Because the density of the gas in the tubular pile (1) is far less than that of water, no matter how large the air pressure in the tubular pile (1) is, in the tubular pile (1), accumulated water is always positioned at the lower part of the tubular pile (1), and the gas is always positioned at the upper part of the tubular pile (1). The air transmission device (8) and the air pipe (7) are used for increasing air pressure to the interior of the tubular pile (1), when the air pressure in the tubular pile (1) minus the atmospheric pressure on the ground surface is large enough, accumulated water in the tubular pile (1) can flow out of the ground surface through the water outlet pipe (3), and the purpose of water drainage is achieved. In the tubular pile precipitation device, a one-way valve (9) for preventing accumulated water or air in the tubular pile (1) from flowing back to the soil can be arranged at the water flow channel (5) or in the tubular pile (1). If the one-way valve (9) is not arranged, after the air pressure in the tubular pile (1) is increased, gas or water can partially flow back to the soil body, but the resistance of the soil body is large, and the water outlet pipe (3) is opened on the ground surface and has small resistance, so that accumulated water in the tubular pile (1) can still be discharged from the ground surface. If a one-way valve (9) is arranged, the precipitation effect is improved by adding a device. In foretell tubular pile precipitation device, can install control valve (10) on foretell outlet pipe (3), control valve (10) are fluid switch, can control the air and flow backward to in tubular pile (1), and the tubular pile (1) evacuation of being convenient for improves the precipitation effect, when evacuation in tubular pile (1), connects trachea (7) on the upper portion of tubular pile (1), and the implementation effect can be better.

This patent includes, but is not limited to, other construction methods that may be substituted by those skilled in the art.
