Abstract

In the present invention, when the pipeline is buried in a complex urban area, the first oscillation tool and the final arrival tool for tunnel installation are installed in the method of laying the pipeline by using the tunnel without fixing the ground due to traffic impairment. I use it.

Since these work areas are essential for tunnel installation and work areas should be installed in a complex place in the city center, the work area should be minimized and should be installed in a short time so as to minimize the inconvenience in traffic or traffic, and also the noise generated by the work. The present invention relates to a method of constructing a work tool by injecting circular steel into the ground to reduce vibration dust and the like to have a minimal impact on the surrounding environment.

According to the present invention, ① When mounting the work tool on the sub-land, the indenter is mounted at the press position of the round steel work tool and ② the pinned steel is precisely mounted to the inside of the presser. Fix it. ③ Excavate the soil in the circular steel working zone by the excavator and operate the indenter to press the circular steel into the ground and install the circular steel to the planned depth. ④ The indentation and construction method of the work tool using the indenter is provided, which consists of the process of completing the work by the circular steel reaching the planned depth, excavating the internal soil, laying the underwater concrete on the bottom, and pumping the water after curing. .

Description

Clamp-build a method for temporary-facility and structure using pressure machine}

In the present invention, the conduit is installed on a public road, but due to noise, vibration, etc., the influence of the surrounding area, traffic restrictions, construction cost, etc. must be fully considered, and in recent years, many non-opening methods for laying conduits have been adopted.

These facilities are often installed in complex urban centers, so they should be able to work in as narrow a place as possible, the construction should be simple and economical.

Even if the non-opening method for laying the conduit is adopted, the oscillating and reaching tools must be installed within 50m ~ 300m to excavate underground tunnels. For the installation of these tools, H-pile, In case of using liner plate and supporting ground method, seat pile, liner plate and injection of chemical solution are used in areas with high groundwater level, but it takes long construction period, wide working space is required, There were many disadvantages such as groundwater contamination by chemical injection and increase of construction cost.

The purpose of the present invention is to solve the disadvantages of the prior art, by using the indentation reaction force and rotational force of the indenter by press-installing the steel facilities fabricated to the desired size in the ground to increase the simplicity and safety of construction, and to solve the traffic obstacles and In order to reduce construction costs, it is to provide a press-fitting construction method for various facilities using a press-fit machine.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in FIG. 1, when the work tool is to be installed in the local class or less, an indenter is installed outside the circular steel facility so that the indentation reaction force of the facility can be supported by the indenter weight.

Next, as shown in FIG. 2 fixedly mounted to the inside of the indenter made of steel, etc. for the temporary object of the construction, and as shown in FIG. At the same time, earth and sand are excavated and excavated by an excavator such as a grab bucket or a Kremsel, and when the facility is located to the planned depth as shown in Fig. 4, the underwater concrete is poured.

The construction is completed when the press-fitting of the facility is completed in the above process and the water inside the facility is pumped.

As described above, the present invention is a method of injecting the facilities into the ground using the self-weight and rotational force of the indenter when constructing various facilities in the city center adjacent to the existing structure, so that the construction of various facilities can be very simple and widely applied. Unlike the construction method that installs the facility in the ground by self or reloading, it is indented by the indenter, so that the influence of surrounding ground is small and does not adversely affect the existing structure. As a result of indentation, it is possible to reduce the occurrence of inclination and facilitate the correction, as well as to remove the auxiliary method for the provision of construction equipment or the order when installing work tools as in the prior art.

In particular, as shown in the figure, if the indenter is simply mounted and settled at the location where the facility is to be built, the construction of the object of construction is completed when the facility is driven and excavated by the usual supporting indentation device, so the construction can be easily performed even in a narrow place. Not only is it less expensive, there are fewer noise, vibrations and traffic obstacles, and there is an advantage in the safety of hebbing and Boley because it performs underwater excavation, which makes the groundwater level unchanged in the process of indenting facilities.

As described above, the present invention is very simple in construction by installing excavation while pressing the construction object by the press-in reaction force of the supporting press-in device in the construction of facilities in the complex city with many constraints. It is not necessary, and it can be installed in a narrow place, and it is possible to build various types of facilities without adversely affecting existing structures due to the drastically reduced occurrence of noise and vibration, which are the targets of residents near construction sites, and no change in groundwater. Compared with the conventional structure construction method, it is an excellent invention that provides various advantages.
