Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an underground pipe burying device.

The conventional underground pipe burying method will be explained with reference to Figs. 1 to 4. First, as shown in Fig. 1, the pavement is cut and crushed using a road cutter, hydraulic breaker, or road crusher a, and then as shown in Fig. 2. As shown in Figure 2, the underground structure at the sheet pile driving position c is investigated using a probe rod or a metal detector b to determine the pipe burial position and the sheet pile driving position, and then a pile driving machine or a sheet pile pressing machine is used to investigate the underground structure at the sheet pile driving position c. Driving the retaining sheet pile (pile), then using human power (scop) and mechanical power (column shell, backhoe, hydraulic shovel) as shown in Figure 3.
Excavation is carried out using a hydraulic excavator d or a belt conveyor, and the dump truck e is used for subsequent transportation.While the earth retaining sheet pile f that has already been driven is erected with support g, In order to restore the pipe by burying it, and during non-working hours, a crane vehicle h is used to lay down iron plates (reconstruction plates) i, as shown in Fig. 4.

In the underground pipe burying method, (2) many steps are dependent on human labor, making it difficult to improve construction efficiency and construction accuracy, and the construction unit cost tends to be high. () There is a lot of dangerous work involved, such as digging in deep holes, working with cranes, and working near traffic jams. Also, because most of the work is done at night, the working environment is poor and safety is low. () In areas where there are many underground structures, the only option is to rely on manual labor, which dramatically reduces construction efficiency. (2) In order to allow vehicular traffic to pass outside of working hours, an extra step of lining, shown in Figure 4, is required. () Vehicle traffic will be severely restricted during the work. () Sediment produced by injecting the chemical solution must be treated as waste soil. (2) There were problems with negative impacts on local residents due to noise, vibration, dust, etc.

The present invention addresses the above-mentioned problems, and includes a work machine body that forms a gently sloping road surface that can be passed by general vehicles on the upper part and a traveling device on the lower part. The machine is equipped with a pavement crushing device that collects and carries out crushed paving materials, and a guide rail installed from the front to the rear of the work machine body excavates and drains the ground after the pavement has been crushed. Excavation and soil removal equipment,
movably supporting an earth retaining device for erecting sheet pile supports and a lining device for laying restoration boards on top of the excavated portion;
This underground pipe burying device is characterized in that a sheet pile press-in device for press-fitting sheet piles is movably supported by another guide rail provided from the front to the rear side of the work machine body, and its purpose is The purpose of this invention is to provide an underground pipe burying device that can efficiently bury underground pipes without being affected by underground objects and without interfering with traffic.

Next, the underground pipe burying work device of the present invention will be explained with reference to an embodiment shown in FIGS. A road surface a with a gentle slope is formed, and a traveling device 7 is provided at the bottom. Further, within the working machine main body A, various devices are suspended and supported in order from the front part (see F) to the rear part. Next, to explain these devices in detail, 1 is a pavement crushing device, which is composed of cutters, scarifiers, etc., and cuts and crushes road pavement. Further, 2 is a crushed material transport device, which collects and transports crushed paving materials. Reference numeral 3 denotes a sheet pile press-in device, which consists of a device for continuously feeding sheet piles and a device for press-fitting them into predetermined positions, and can be moved by a guide rail on the side of the main body.
4 is the excavation and earth removal equipment, which includes a water jet excavator that excavates with high pressure water, a mud water pump,
It consists of muddy water treatment equipment and a workbench for workers who monitor and direct the work. Further, 5 is an earth retaining device (a device for installing sheet pile supports), which consists of a crane for transporting support materials and a workbench. Also, 6 is a lining device (a device for lining), which consists of a crane for transporting lining plates and a workbench. Note that each of the above devices can be moved along a guide rail together with an attached workbench (a workbench on which a worker remotely controls monitoring and commands of the device). In addition, for curve execution, work body A should be made into a center-folding type.

Next, the operation of the underground pipe burying work device will be explained. After the pavement crushing device 1 and the crushed material carrying out device 2 crush and carry out the paved road surface, the excavation/earth removal device 4 and the earth retaining device 5 perform the excavation necessary for burying the underground pipe. This excavation is performed using high-pressure water that does not damage buried objects, and soil removal is performed by continuously sucking in and treating muddy water. In addition, sheet pile press-in will be carried out in parallel with excavation. This work is carried out while being monitored by workers using underground radar, TV cameras, or the naked eye, but the excavators and press-in equipment themselves are also equipped with safety devices to prevent accidents during the work. . Carrying in necessary materials, buried pipes, lining boards, etc. using the earth retaining device 5 and lining device 6;
During the installation and the above-mentioned series of operations, vehicles on the work equipment can pass through the road surface a.

As described above, the underground pipe burying work device of the present invention uses the pavement crushing device and the crushed material transport device to crush and transport the paved road surface, and then crushes the pavement using the excavation and earth removal device that can be moved forward and backward using the guide rail. At the same time as the ground is excavated and removed, sheet piles are pressed in using a sheet pile press-in device, and then necessary materials, buried pipes, lining boards, etc. are brought in using an earth retaining device and a soil covering device that can be moved forward and backward using guide rails. , perform the installation. In other words, underground pipe burying work is carried out continuously. Since the above-mentioned sheet pile press-in work is performed under the full supervision of workers and preparatory work (cloth digging, etc.) is unnecessary, underground pipe burying work can be carried out efficiently.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to these embodiments, and can be modified in various ways without departing from the spirit of the invention. be.
