Description

Horizontal excavator to gather underground water

The present invention relates to a horizontal excavator for underground rock water harvesting, and more particularly, by allowing only the fixed bed to be rotated in a state where the horizontal excavator is located in the underground catchment, even if the horizontal excavator is not lifted again, the position of the excavating shaft can be easily moved. A horizontal excavator for underground rockwater harvesting that can be modified.

In general, a horizontal excavator for underground rockwater harvesting is a device for harvesting high quality groundwater from aquifers existing in underground hard rock layers.It is installed in underground wells and excavated to the hard rock side around the wells. It is used.

That is, before using the horizontal excavator, the ground surface is vertically excavated through various heavy equipment to form the underground catchment, and the horizontal excavation work is carried out under the condition that the horizontal excavator is installed inside the underground catchment.

Therefore, the following describes the configuration of the horizontal excavator is already filed as follows.

Figure 6 shows a "horizontal excavator for underground rock catchment" (hereinafter referred to as a conventional invention) of the Republic of Korea Patent No. 250580 registered by the applicant of the present application, and is supported on the inner wall of the excavated underground water collection wells horizontal It is made of a predetermined width and length to be installed so as to have a fixed bed 200 having a pair of guide rails 201 installed in parallel with the upper, and disposed on the guide rails 201 of the fixed bed 200 The conveying frame 203 is installed to be movable in the front-rear direction by the operating means 202, and the compressed air is supplied to the inside at high pressure while being reversed by the driving means 204 in the center of the conveying frame 203 Excavation and propulsion shaft 205 is installed so as to be ventilated, and excavation unit to be excavated while hitting the hard rock layer as the main force and compressed air transmitted in succession to the tip of the excavation and propulsion shaft 205 It is configured as a 206.

Therefore, the operation of the horizontal excavator configured as described above is as follows.

First, the fixed bed 200 is supported in the work space secured to the lower part of the basement well, which has been excavated vertically up to the hard rock layer, and is installed horizontally, thereby preparing the work by connecting the excavation unit to the tip of the excavation propulsion shaft 205. do.

After the work preparation is completed, the external air compressor is operated to supply the compressed air to the excavation unit via the excavation propulsion shaft 205 along the compressed air supply pipe connected to the air supply hose.

At the same time, the transfer frame 203 rotates the excavation propulsion shaft 205 with the drive means 204 while advancing to the forward and backward operation means 202 and compresses the air to the excavation unit 206 connected to the excavation propulsion shaft 205. With propulsion.

When compressed air and propulsion force transmitted from the excavation propulsion shaft 205 are transmitted to the excavation pipe via the connecting rod of the excavation unit 206, the hammer bit at the tip of the excavation pipe is moved forward and backward to drill a horizontal body water hole. To dig.

However, when radially digging around the underground catchment through the horizontal excavator, the existing horizontal excavator should be lifted again to change its position, thereby reducing the efficiency of the excavation work and of course the cost of the excavation. There was a problem such as wasted.

In addition, the horizontal excavator is fixed only to the inner wall of the underground water collection well, but as the horizontal excavator is easily inclined due to the vibration generated during the excavation, it also has a problem that it is not possible to perform precise excavation.

In addition, the complexity of the configuration of the means for rotating the excavation and propulsion shaft has a problem that the unit price of the product increases.

Accordingly, the present invention has been invented to solve the conventional problems as described above, by allowing only the fixed bed to be rotated in a state where the horizontal excavator is located in the underground catchment, the position of the excavation propulsion shaft can be easily changed. It is.

In addition, by fixing the horizontal excavator at the same time as well as the side wall of the basement well, it also has the purpose of preventing the horizontal degree during the excavation operation.

It is also intended to rotate the excavation propulsion shaft with a hydraulic motor to maximize the output of the propulsion shaft.

The present invention for achieving the above object, in the horizontal excavator equipped with a transfer frame that is moved back and forth in the upper portion of the fixed bed, the lower portion of the fixed bed is fixed to enable the rotation of the fixed bed, the fixed Each vertical edge of the bed is equipped with a plurality of vertical extension, fixed horizontally on both front and rear sides of the fixed bed is equipped with a plurality of horizontal extension to be in close contact with the side wall of the underground collection well, the upper part of the transfer frame through a hydraulic motor It is characterized in that the driving propulsion shaft drive unit is mounted.
