Description

The method of con struction and apparatus (KY-2 pipejacking and propulsion method) for propulsion lage diameter steel pipe}

The present invention relates to a large-diameter steel pipe pressurization propulsion method (KY-2 propulsion method) and the device, which will be described in detail, by pushing the large-diameter steel pipe into the forwarding device and at the same time the self-propelled skid loader inside and outside the large-diameter steel pipe into the skid loader. The present invention relates to an eco-friendly large-diameter steel pipe press-fitting method (KY-2 propulsion method) and a device for installing a excavator and a soil extraction device to quickly take out the soil generated during excavation and excavation, and to treat it with a soil treatment device installed at the rear.

In recent years, the concentration of population and economic centers has accelerated around large cities, and the classification of administrative districts in Korea has become widespread. The necessity of three-dimensional use of underground space is rapidly increasing for various pipelines directly related to economic life such as sewerage, communication, electricity, and city gas.

In the case of domestic, so far. Most of pipeline construction such as sewer, communication, electric power, city gas performed by open construction method. However, in order to bury pipelines by using excavation methods in urban areas, traffic obstacles are not only large, but also easy access and excavation of roads due to various civil complaints are increasingly severely regulated. In particular, there are strict regulations on the method of excavation and burial widely in roads, busy streets, dense housing and neighboring areas, as well as pipeline construction such as vehicle-only roads, highways, railroads, dikes and river crossings. It is true. In the case of pipeline construction, which is newly constructed due to the increase of underground buried materials, the construction of deep underground underground is required. Due to the change of construction environment, pipeline construction by propulsion drilling method is occupying a lot of market share in Korea.

However, in Korea, where the introduction of the propulsion method is short, the recognition level of the propulsion method is still very low, and the propulsion method is not recognized as a completed method in the geotechnical field such as the existing tunnel method. At present, however, Japan, the forerunner of the propulsion method, is setting up the propulsion method as an independent field different from the large-diameter tunnel method, and is making great efforts to develop new propulsion technologies.

If you look at the general soil excavation method of foreign countries, the method of sequentially propelling the propulsion pipe from 800mm to 3300mm by the hydraulic jack installed in the forward device is divided into manpower excavation propulsion method and semi-shield method (mechanical combined propulsion method). Can be.

The manpower excavation propulsion method is a method of attaching a blade or shield blade to the tip of the propulsion pipe, and excavating the earth and sand by manpower and injecting the propulsion pipe into the hydraulic jack to bury the pipe body in the ground. One of them is the open (round) type propulsion method, after attaching a blade to the tip of the pipe, and excavation work of the soil is carried out by manpower. The excavated soil is transported in a pipe by a truck and taken out of the forwarding device. The propulsion system is equipped with a hydraulic jack, reaction wall, rail, and square rod to propel the tube body. The ground of the excavation target is open because the end of the pipe is open. If the ground is difficult to stabilize, the auxiliary method such as chemical injection method is used in parallel, but this method is not applicable to aquifer fluid sand. This construction method is applied to construction sites of 30m to 70m, which has a relatively short driving distance (see Fig. 1).

The medium pressure jack propulsion method, which is another public corporation, has been developed. This is limited to the axial resistance of the pipe to be pushed by the open hydraulic propulsion facility and the allowable reaction force of the reaction wall, while the propulsion resistance increases as the propulsion distance is increased. At the driving distance of more than this, a medium pressure jack is installed in the middle of the propulsion pipe to reduce the pressure of the jack pressure of the open hydraulic propulsion facility (see Fig. 2).

The curve propulsion method, which is another method, has been inevitably required to perform curve propulsion with the increase in the ratio of long-distance propulsion as the propulsion technology is developed. The difference between the straight line propagation and the straight line propagation is that it is difficult to survey (it is necessary to carry out the surveying equipment inside the pipe), and it is easy to damage the pipe due to the unbalanced load on the connection surface of the pipe. It is necessary to stabilize the ground excavated larger than the outer diameter during the propulsion, and it is difficult to change the direction of the blade of the tip of the propulsion pipe and it is easy to be zigzag-propelled (see Fig. 4).

Semi-shield method includes mud water pressurization method and earth pressure balance propulsion method, and water pressurization pressurization method is a closed mechanical excavation shield method and has a bulkhead between the excavation shield and excavation. Mud water is charged to the shield side, the water pressure higher than natural water pressure and the action of the Mud-film are excavated to independence of the shield, and the earth and sand are sent to the water treatment facility through the pipe together with the mud water to separate the soil and water. The water containing the separated fine particles is sent to the shield and circulated for use (see Fig. 5).

The earth pressure balanced propulsion method is a method of excavating the machine while preventing the collapse of the ground by generating earth pressure in the bulkhead with the shield and the bulkhead like the mud water pressurized propulsion method. Xantry is discharged with a screw convayor and discharged out of the forwarding device by a carriage (see Fig. 6).

Although there are various construction methods as described above, there are many difficulties in introducing domestic advanced propulsion techniques in various conditions.In Korea, the basic ground construction of domestic roads is very irregular and there are many poorly constructed roads. Due to the lack of awareness of the propulsion method, the construction cost of this field is excessively low to construct by adopting the Japanese advanced propulsion method, and the regular continuity of the domestic geological soil is low.

In order to solve the problems described above, in the present invention, the large-diameter steel pipe is propelled and pressed at the same time as the self-propelled skid loader in and out of the large-diameter steel pipe to install an excavator, earth and sand extraction device in the skid loader is generated during excavation and excavation It is an object of the present invention to provide an eco-friendly large-diameter steel pipe indentation and propulsion method (KY-2 propulsion method) and a device for quickly discharging soil and treating it with a soil treatment apparatus installed at the rear.

In order to achieve the above object, the present invention is a skid steer loader by inserting a skid loader into and out of a large diameter steel pipe at the same time to push-in the large diameter steel pipe for a diameter of 2100mm or more and 3400mm in the steel pipe pressurization method for the soil It is related with the eco-friendly large-diameter steel pipe press-injection method (KY-2 propulsion method) and the device which installs an excavator and a soil extraction device on the ground, and quickly removes the soil produced during excavation and excavation, and processes it with the soil treatment device installed at the rear. .

The skid steer loader used in the present invention performs work while moving quickly and effectively in a narrow space of a construction site, and the driving power is equipped with various equipment using a hydraulic pump and a hydraulic motor based on the rotational force generated by the mounted engine. It is a common construction equipment used for construction.

The following six characteristics are mentioned as a characteristic of this invention.

First, the excavation speed is high and the working efficiency is high compared to the conventional manpower excavation or skid loader only excavation method by mechanical excavation by high pressure water (water) injection and excavator.

Second, by devising a self-propelled excavation system equipped with an electric drive excavation system on the skidder arm, the excavation of the upper and lower parts of the soil in the propulsion pipe as well as the left and right part excavation were possible, and the work efficiency was also improved.

Third, as the driving system of the excavator, electricity was used to eliminate the air pollution in the propulsion pipe and reduce the noise.

Fourth, by installing a screw conveyor for earth and sand discharge on both sides of the skid steer loader, Nisu mixed soil discharged by the excavator is moved to the earth and sand discharge device connected to the rear of the skid steer loader at high speed. The barrier wall was installed to descend to the bottom of the pipe when the soil was discharged, and as the skid loader moved, the skid loader was free to move and the soil was not leaked to the rear of the skid loader.

Fifth, the earth and sand discharged from the upper part of the earth and sand discharge screw conveyor were moved to the part of the earth and sand discharging device installed with the vibrating screen conveyor first. Was allowed to separate. Also, the gravel was moved to the top of the gravel loading box by moving upward along the vibrating screen conveyor. Nisu and Tosa, which passed through the vibrating screen conveyor, were discharged out of the forwarding system through the Tosai convey pump and the earth and sand discharge pipe. And when a certain amount of gravel is accumulated in the gravel loading box, the lift door is opened and transferred to the transport vehicle and discharged out of the forward device.

Sixth, the soil discharge device was manufactured in the form of a trolley for good operation and connected to the linkage of the latter part of the skid loader.

The present invention can be broadly classified into four types: an excavation device, a skid loader and a screw conveyor device for soil discharge, a soil discharge device, and a soil treatment device.

First, the excavation device is composed of electric drive device, excavation shaft, excavation blade, excavation bit and high pressure water pipe and spray nozzle attached to the front part of the arm of the skid loader and air pollution prevention and noise reduction in propulsion pipe. For this purpose, an electric motor using three-phase 220V electricity as a power source was used as a driver, and a pipe with high-pressure water flows inside the excavation shaft. And the tip of the excavation blade was equipped with an excavation bit to minimize the damage of the excavator and to maximize the excavation efficiency. In addition, the high pressure water injection nozzle is installed in the center of the excavation bit, and the high pressure water injected through the excavation bit allows the excavation and collapse of ordinary soil to be made at a high speed. By attaching the electric drive excavation system to the arm of the skid loader, it is possible to effectively excavate the upper and lower partial soil in the large diameter steel pipe, and to effectively excavate the soil of the left and right parts by driving the wheel of the skid loader left and right. I could do it.

Second, as a skid loader and a screw conveyor device for earth and sand discharge, the skid loader method is adopted for quick excavation work and movement in large diameter steel pipe, and the screw conveyor for soil discharge is inclined at the upper end of the rear side of the skid loader. The device was installed so that the mixed mixed soil was smoothly moved to the soil discharge device connected to the rear of the skid steer loader. In addition, earth and sand adjustable walls are mounted on the front of the skid loader to prevent the earth and sand from the front of the skid loader from moving to the rear of the skid loader, and the screw conveyor for soil discharge is also adopted by the electric system.

Third, the earth and sand discharge device, the earth and sand that has been moved to the earth and sand discharge device through the screw conveyor for earth and sand discharge is separated into the soil and gravel, and the mixed mixed soil is the forwarding device through the earth and sand transfer pump and the earth and sand discharge pipe, the gravel is transported by manpower It was loaded in the car and discharged out of the forward device. The earth and sand, which is moved to the earth and sand discharge device through the screw conveyor for earth and sand discharge, is first moved to the vibrating screen conveyor with the soil and gravel separated by the water pressure sprayed from the sprinkling pipe, and the gravel failed to pass through the vibrating screen conveyor of a certain mesh size. Was moved upwards along the vibrating screen conveyor to the gravel loading. When gravel is full in gravel loading, lift door of gravel discharge port is opened and transferred to manpower transport vehicle and discharged to outside. The earth and sand passing through the vibration mesh with the needle water are discharged to the forwarding device through the soil pump and the soil discharge pipe. In addition, this soil discharge device is manufactured in the form of bogie, which makes it easy to operate and is connected to the latter part of the skid steer loader.

Fourth, the earth and sand treatment system is mainly composed of soil sediment and sewage separation device, filtration device, and filter water storage tank, and the sediment and sedimentation device is used for the natural sediment and sewage transported from the earth and sand discharge device in the propulsion pipeline. It is a device for sedimentation and primary separation. The material is manufactured using FRP (reinforced plastic) for easy transportation and installation, and a fixed connection device is attached for easy connection with the filtration device.

The box is 5m long, 1m high and 2.5m wide, and has a sloped bulkhead with a lower slope in the middle of the other side so that the soil discharged from the nis and sewage discharge pipes is naturally deposited on one corner. At the beginning, a nisu connection passage connected to the filtration device was installed so that the sewage water separated after sedimentation was naturally introduced into the filtration device. On the other side of the sedimentary sediment, the sediment discharge passage was installed so that the sediment separated from the filtration device was discharged to the sedimentation sedimentation site. In addition, a ladder-type external soil discharge conveyor was installed to facilitate the discharge of the deposited soil.

Filtration device is a device that filters more cleanly (except earth and sand over 0.02mm) in order to recycle and circulate the sewage separated from sedimentation and sewage water separation device. In order to increase durability, it is assembled with steel plate and steel of 1m width. Inside the device, there is a driving device of 0.02mm mesh wire mesh, a storage tank for filtered nisu, and a submersible pump and connecting pipe for smooth movement to the filtered water storage tank. There is a soil discharge passage to smoothly flow into the soil sedimentation tank. In addition, a cleaning outlet for cleaning the water tank, and a sedimentation and sewage separation device, and a fixed connection device for smooth connection with the filtrate storage device were installed.

The filtrate storage tank is a device to store the water used for excavation work in the propulsion lead pipe. It is made of FRP (reinforced plastic) of 5m in length, 1m in height and 1.5m in width. In this device, a connecting passage was installed so that the recycled water flowed smoothly into the filtered water storage tank through the filtration device. A filtrate fill inlet was installed. In addition, a cleaning outlet was installed at the bottom for cleaning the filtrate storage tank, and a fixed connection device was attached for smooth connection with the filtration device.
