Abstract

(57) [Summary] [Purpose] To provide a drainage device for root cutting work that does not take time and effort to install a submersible pump and a drain hose and does not interfere with the work of an operator or is damaged during the work. That is. [Structure] The drainage device 1 for root cutting work is configured by using a horizontal single pipe 4 of a safety handrail 3 which surrounds the circumference of the root cutting part A, and is installed in a cauldron C at the root cutting bottom B. Submersible pump 2
And a horizontal single pipe 4 in the safety handrail 3 and a connection hose 6 connecting the horizontal single pipe 4 and the sand settling tank 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage device for root cutting work that drains spring water during root cutting work.

[0002]

[Prior Art]

 In the root cutting work to build the basement floor of the building, when the root cutting reaches the groundwater level or below, there is spring water.Therefore, this was collected in the cauldron at the bottom of the root cutting and drained by the submersible pump. . Normally, this drainage was carried out by connecting the drainage hose 20 of the submersible pump 10 to a ground sand basin 30 as shown in FIG.

[0003]

[Problems to be solved by the device]

 However, there is a problem in that it takes time and effort to install drainage pumps and drainage hoses when such a drainage has a long distance from the kettle to the sand settling tank. In addition, as for the above drainage, the kettle and the sand settling tank are connected by the drainage hose, and this drainage hose is left undisturbed on the root cutting bottom or the like, which disturbs the work or the drainage hose is stepped on the operator. There was a problem that it was damaged and damaged.

The present invention has been made in view of the above problems, and an object thereof is to install the submersible pump and the drain hose in a trouble-free manner, which hinders the work of an operator, or It is to provide a drainage device for root cutting work that is not damaged inside.

[0005]

[Means for Solving the Problems]

 The gist of the present invention to achieve the above-mentioned problems is the submersible pump installed in the kettle at the root cutting bottom and the horizontal single pipe in the safety handrail that drains the spring water pumped by the submersible pump to the sand settling tank. And a connecting hose connecting the horizontal single pipe and the sand settling tank.

[0006]

[Action]

 According to the drainage device for root cutting work of the present invention, the submersible pump can be easily installed by draining the spring water pumped by the submersible pump to the sand settling tank through the horizontal single pipe in the safety handrail. Since the drain hose is not left undisturbed on the root cutting bottom, etc., safe work can be performed without disturbing the worker's work.

【Example】

 Hereinafter, an embodiment of the drainage device for root cutting work of the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view showing a drainage device 1 for root cutting work of the present invention installed in a root cutting part A. The drainage device 1 for root cutting work is a horizontal unit of a safety handrail 3 surrounding the root cutting part A. The pipe 4 is used, and the submersible pump 2 installed in the cauldron C of the root cutting bottom B, the horizontal single pipe 4 in the safety handrail 3, the horizontal single pipe 4 and the sand settling tank 5 are provided. And a connecting hose 6 for connecting the.

The submersible pump 2 is connected by a drain hose 7 to a horizontal single pipe 4 of a safety handrail 3 provided around the root cutting portion A, and the horizontal single pipe 4 is connected to a sand basin 5 by a connection hose 6, respectively. The spring water is drained. Therefore, when installing a plurality of submersible pumps 2 on the root cutting bottom B, drainage should be performed using the other horizontal single pipe 4 in one safety handrail 3 and the horizontal single pipe in this safety handrail 3 If 4 is not enough, the horizontal single pipe 4a of the other safety handrail 3a can be used.

The drain hose 7 and the horizontal single pipe 4 are connected by an L pipe 8a, the horizontal single pipes 4 are connected by a socket pipe 8b, and the horizontal single pipe 4 and the connection hose 6 are connected by a horizontal single pipe. It is assumed that the pipe 4 is inserted into the connection hose 6 and that the hose clamp 8c tightens the connection. Therefore, the drainage device 1 for root cutting work is extremely easily installed by connecting the submersible pump 2 to the horizontal single pipe 4 by the drainage hose 7 and connecting the connection hose 6 to the horizontal single pipe 4 by the above connection method. It can be dismantled and can be easily dismantled even after the end of drainage.

[0010]

[Effect of the device]

 Since the drainage device for root cutting work of the present invention is constructed by using the horizontal single pipe of the safety handrail which surrounds the periphery of the root cutting part, it can be installed and disassembled extremely easily.

Unlike the conventional case, the drain hose is not left messed up and the minimum necessary piping is required, so that the drain hose does not interfere with the work or the drain hose is not damaged.
