Abstract
Description
The present invention relates to a high-strength dry construction method using inverted T-type expansion excavation and concrete placement of expansion excavation in the case of mechanized dry construction using an expansion crane of an auger crane, and more specifically, an electric pole using an expansion excavator of an auger crane. Excavation of embedded poles to be embedded and forming an inverted T-type expansion excavation part, by placing the steel concrete on the expansion excavation and supporting the pole using the concrete foundation structure of the inverted T-type expansion excavation, Inverted T-type expansion excavation and concrete placement of expansion excavation using auger-crane excavation screw, which secures strong vertical support of the pole without installation, as well as improve workability and support strength by simple work process. It relates to the high strength dry construction method used.
In general, when constructing transmission poles and telecommunication cables in the construction of transmission and distribution lines and communication lines, etc., a method of installing poles and ground wires to reinforce the unbalanced tension of the wires and communication cables to prevent the poles from tilting or falling down. You are choosing.
Such general branch line and branch line construction method is disclosed by Patent No. 710649, Patent No. 727279, Patent No. 740013, and Patent No. 761778, which are devised by the present applicant.
The ground roots used in modern ground roots construction methods are rectangular roots of 0.7 m and 1.2 m, and round roots of 43 cm in diameter and 62 cm in diameter corresponding to the above values.
Here, the reason for the difference between the standard and the shape of the branch line as described above is for the construction of a facility having an appropriate strength according to the tension according to the design load of the facility installed in Jeonju. This is rapidly increasing, and as the population increases, the power supply facilities are also becoming larger.
In other words, the current distribution system in Korea is equipped with a distribution voltage of 22.9kV, but due to the current flow of expansion of the large-capacity distribution supply capacity, research is being conducted to increase the distribution voltage.
For this reason, in the past, the construction of boosting voltage from 110V to 220V was implemented nationwide. At this time, the distribution voltage of Korea was changed from 6.6kV to 22.9kV.
Here, if power demand increases or the distribution voltage is changed, all the equipment necessary for constructing a power facility is changed, and the supporting capacity of the poles supporting the power facility is a very important part.
In addition, in terms of the transition point of the distribution line, all the equipment and other related equipment installed on the electric pole are all derived from the design load, and the facility is installed in consideration of the load capacity within the range that the branch line can overcome the tension of the line so that the electric pole is not damaged. Because of this, if these problems are solved, it will be possible to accumulate and install more power equipment-related equipment on one track.
For example, if there are areas where electric poles are erected on both sides of the road and the distribution lines are used, it means that heavy load facilities on both sides can be accumulated by using only one side of the road if high-strength branch construction is possible. In addition, the installation of large-capacity power lines to expand the power supply capacity as power demand increases, and the power facilities become more abundant at the point where various problems such as damage to the surrounding environment are brought about by the land occupancy and land occupancy. When reflecting the trend of increasing power facilities, solid support capacity of the previous week is required.
Accordingly, the applicant of the present invention newly manufactured circular branch roots having a diameter of at least 72 cm as shown in Korean Patent No. 0903054, and an excavation unit for embedding the circular branch roots is equipped with a hydraulic expansion drilling screw on the auger crane through hydraulic pressure. The expansion and contraction of the expansion and contraction blades enables the excavation of the ground root buried portion and the ground rod interfering portion to be effectively excavated, and the enlarged circular ground root edge greatly increases the opposing surface area with the landfill soil and improves pull resistance. Excavation process can be mechanized without manual operation by the excavation screw with the hydraulic expansion and contracting blade, so it can be applied to the existing method of circular branch line using manual expander, and it has fast construction time and high quality construction completion. Round branch line and hydraulic expandable features to achieve Hanba complex has proposed a high strength branch geunga construction method using a screw.
However, in general, the pole is divided into general purpose, heavy load, and high strength pole according to the design load (total weight of the installed pole) .The construction method according to the pole's strength is not provided separately. It was only to install additionally or to install branch lines.
Therefore, in the poles of heavy load or more, even if the poles or branches were properly installed due to the weight and tension of the wires, the poles were inclined frequently.
In addition, depending on the site conditions, there is a problem that often occurs when the branch line installation is impossible or can not be properly installed according to the tension, it is not only difficult to omit the branch line construction, but also requires multiple excavation processes to construct the ground roots It also had problems that brought about the hassle of construction.
The present invention has been made in order to solve the above problems, when forming a pole insertion hole for embedding the pole poles, but forming an inverted T-type expansion excavation in the pole insertion hole and the pole insertion hole, the expansion excavation portion By placing the crude steel in the concrete and supporting the pole using the concrete foundation structure of the inverted T-type expansion, it secures strong vertical support force that acts the same on the outer circumference of the pole without the need for separate pole poles, and increases the supporting load. It is possible to omit the branch line, and in particular, the reverse T-type expansion excavation and expansion excavation part using the auger-crane excavation screw that can greatly improve the workability and support strength of the dry construction work by the simple work process. It is an object of the present invention to provide a high-strength dry construction method using concrete pouring. .
As a specific means for achieving the above object, by using an auger-crane-mounted drilling screw having a spiral drilling blade and a spiral screw oozing in the transverse direction by hydraulic pressure in the state that the expansion drilling blade of the drilling screw is reduced Using the screw only, the ground where the pole is embedded is vertically excavated to have a diameter larger than the outer diameter of the pole, thereby forming the pole insertion.
After excavating the pole insert, the expansion and contraction of the excavation screw in the state in which the drilling screw expansion and expansion by hydraulic pressure to expand the excavation of the expansion excavation portion in which the steel concrete is poured in communication with the insertion of the pole,
The pole pole is inserted into the pole pole, and the expansion can be achieved by placing the steel bar in the concrete.
As described above, the high-strength dry construction method using reverse T-type expansion excavation using the excavation screw for auger crane and concrete placing of the expansion excavation, forms an electric pole insertion hole when excavating the ground in which the electric pole is embedded and the insertion of the electric pole insertion hole. Form an inverted T-type expansion excavation inside, and cast the steel concrete with fast hardening speed in the expansion excavation to support the concrete foundation structure of the inverted T-type expansion on the outer circumferential surface of the pole. In addition, the strong vertical support of the pole is secured, it is possible to increase the support load and to omit the branch line, and in particular, to achieve a significant improvement in the workability by simplifying the work process due to the simplified excavation work.
