Abstract

PURPOSE:To eliminate the need for external supporting mechanism while making an anchor device compact by a method in which an oil-pressure power is used and the pressing and developing reaction of anchor is absorbed by the anchor itself. CONSTITUTION:Under a condition that the cylinder rod 12 of an oil-pressure cylinder tool is fully expanded, a pipe 11 is fitted on the upper end of a supporting lever 1, and the supporting lever receiver 18 of an oil-pressure cylinder 13 is screwed with the threaded portion (not illustrated) of the supporting lever 1 for connection. These thus connected are penetrated and set in an excavated hole 20 by using the crane boom 21 of a pillar erector car. The oil- pressure pipes 22 and 23 of oil-pressure generating units are connected with the oil-pressure couplers 14 and 15 of the oil-pressure cylinder 13. Afterwards, when an oil pressure is applied in the direction of arrow, the connection between the supporting lever receiver 18 and the supporting lever 1 serves as a force point, and a resistance plate 3 is pressed from above by a pressing and developing force to cause the pipe 11 to be directed downwards. The resistance plate 13 is then opened bilaterally under the guidance of the inductive slope (not illustrated) of a base plate 2 and buried under the ground. Since the pressing of developing reaction of the anchor is absorbed by the connecting point between the oil-pressure cylinder 13 and the supporting lever 1, the need for external supporting mechanism for the pressing and developing reaction can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a branch line anchor, and more specifically, a branch line anchor in which a resistance plate is expanded from side to side along a guide slope of a board provided at the lower end of a support frame, and is buried underground. Concerning improvements to burial methods.

Conventionally, as a means of burying this kind of branch line anchor, the upper part of the vibrator inserted into the support frame is applied with a hammer equipment or the like to apply an impact against the resistance plate aligned with the guiding slope of the board. Either deploying and burying the resistance plate underground, or applying pressure to the pipe with a boom such as a pole-erecting vehicle,
The resistance plate was spread out and embedded along the guiding slope of the board.

In this type of burying method, the suppressing development reaction force applied to the pipe is
Since it acts on a structure other than the anchor (1!!i), there is a problem in that an external support aE is required to support this suppression/deployment reaction force.

Let alone near 11. '), intelligence, telephone, etc. overhead line work,
Due to increased capacity and centralized wiring, the utility poles used are becoming larger and stronger, and underground anchors for branch line foundations used for these are also required to be of large capacity, and accordingly jJ14 construction lJ
In order to cope with the increase in labor costs, construction using a tumbler has become an essential condition.

The present invention was made in view of the above circumstances, and it is simple and easy to use.
The existing problems are solved by the L construction method, and by using hydraulic power, the suppression and deployment reaction force of the anchor is absorbed within the anchor itself, supporting the suppression and deployment reaction force. The objective is to make the device more compact by eliminating the need for an external holding mechanism, and to provide a buried construction method that enables quiet and safe construction.
