Abstract

【課題】従来、電柱の支線のアンカーは強風、地震等に対して、又は地盤が緩い場所において、電柱が倒れることがあります。そのため、アンカーの支持強度をもっと上げなければならない必要性がありました。【解決手段】従来のアンカー埋設は、アンカーをただ埋設するだけでした。本発明のアンカー埋設は、ケーシングを使用して、ケーシングの回転によりアンカーを回転させ、地中を掘削、推進して目的の深さに定着させ、ケーシング上端内よりセメントミルクを流し込み、定着したアンカー及び、アンカー上部周りの土もセメントミルクにより強固に固める装置の発明です。【選択図】図１[Problem] Conventionally, the utility pole anchors may fall against strong winds, earthquakes, etc., or in places where the ground is loose. Therefore, there was a need to increase the anchor support strength. [Solution] The conventional anchor burial was just burying the anchor. The anchor embedment of the present invention uses a casing, rotates the anchor by rotating the casing, excavates and propels the ground, fixes it to a desired depth, and then flows cement milk from the upper end of the casing to fix the anchor. And it is an invention of a device that firmly solidifies the soil around the top of the anchor with cement milk. [Selection] Figure 1

Description

本発明は、アンカーを地中に確実に定着させる装置に関するものです。 The present invention relates to a device for securely anchoring an anchor in the ground.

従来、電柱の支線のアンカーに使用されているアンカーは、強風、地震等に対して、又は地盤が緩い場所において電柱が倒れる事があります。
本発明は、アンカーの支持強度を強化する装置に関するものです。 Conventionally, anchors used for anchors of utility poles can fall down due to strong winds, earthquakes, etc., or in places where the ground is loose.
The present invention relates to a device for enhancing anchor support strength.

特願２０１３−０７０７１５ Japanese Patent Application No. 2013-070715

従来、電柱の支線に使用されているアンカーは、簡単に埋設出来る物や、ただ埋設しただけの物が多くあります。そのため、月日が経つと雨や風、地震等で地盤が弱くなり、アンカーの支持力も落ちてしまいます。 Conventionally, there are many anchors used for the branch lines of utility poles that can be easily embedded or simply embedded. Therefore, when the moon passes, the ground becomes weak due to rain, wind, earthquake, etc., and the support capacity of the anchor also falls.

従来のアンカーは、アンカーをただ埋設するだけですが、埋設したアンカーは元よりアンカーの周りの土までセメントミルクで撹拌して固めてしまえば、アンカーの支持力が増してきます。
そして、本発明の目的は、ケーシングで掘削推進出来る深さまでアンカーをセメントミルクで固めることが出来る装置と埋設方法です。 Conventional anchors simply embed the anchors, but if the embedded anchors are stirred and hardened with cement milk from the beginning to the soil around the anchors, the anchor's bearing capacity will increase.
The object of the present invention is an apparatus and a burying method that can harden an anchor with cement milk to a depth that can be excavated by a casing.

本発明を、図と共に説明すれば、図１のアンカー（１）の円筒体の下端、又は円筒体の外周に支持部（２）が設けられ、アンカー（１）の下端に、又は円筒体の下端に蓋板（４）を設け、下端側の蓋板（４）の底面に、又は２ヶ所共に土を掘削する掘削部（３）を設け、アンカー（１）の円筒体の上部を閉塞する蓋板（４）を設け、上部側の蓋板（４）の中央部上部にアイボルト（５）又はユーボルトを設け、アイボルト（５）又はユーボルトに脱着可能な、アンカーボルト（６）を揺動可能に接続し、アンカー（１）の円筒体の外周に、ケーシング（７）の下端に設けられたアタッチメント（８）と脱着可能に係合する凸部材（９）を設ける。
アンカー埋設機械（１０）のブーム（１１）の先端に垂下された鉛直回転軸を備えた回転駆動機構（１２）の下端に、ケーシング（７）の係合用のアタッチメント（１３)を設ける。 If this invention is demonstrated with a figure, the support part (2) will be provided in the lower end of the cylindrical body of the anchor (1) of FIG. 1 or the outer periphery of the cylindrical body, and the lower end of the anchor (1) or A cover plate (4) is provided at the lower end , and an excavation part (3) for excavating soil is provided on the bottom surface of the cover plate (4) on the lower end side or at two locations to close the upper part of the cylindrical body of the anchor (1). the lid plate (4) is provided, the upper side of the cover plate a central portion upper eye bolt (5) or Yuboruto of (4) is provided, eye bolts (5) or Yuboruto removable, the swingable anchor bolts (6) connected to the outer circumference of the cylindrical body of the anchor (1), Ru provided casing attachment provided at the lower end of (7) (8) and protruding member (9) for desorption engage.
An attachment (13) for engaging the casing (7) is provided at the lower end of the rotation drive mechanism (12) having a vertical rotation shaft suspended from the tip of the boom (11) of the anchor burying machine (10).

アンカー（１）をケーシング（７）内にセットする場合は、ケーシング（７）を地上に寝かせ、ケーシング（７）内に掘削の深さ分の長さのアンカーボルト（６）を入れ、アンカーボルト（６）とアンカー（１）を接続させた後、アンカー（１）をケーシング（７）の下端に設けたアンカー（１）の係合用のアタッチメント（８）に係合させる。
そして、図２の様に、ケーシング（７)を縦吊りにアンカー埋設機械（１０）により吊り上げ、回転駆動機構（１２）の下端のアタッチメント（１３）にケーシング（７）を係合させる。
そして、掘削地点にアンカー（１）の先端を持って行き、回転駆動機構（１２）を回転させることにより、アンカー（１）が地中を掘削して推進して、目的の深さまで掘削したら回転駆動機構（１２）の回転を止める。
そして、アンカー（１）とケーシング（７）のアタッチメント（８）との係合を外し、そして回転駆動機構（１２）の下端のアタッチメント（１３）とケーシング（７）の係合を外す。
そして、ケーシング（７）の上端内より、図３の様に、セメントミルク（１４）又は、モルタル、又は各種土壌固化材を流し込み、ケーシング（７）の下端よりセメントミルク（１４）があふれ出し、ケーシング(７）を回転駆動機構（１２）で回転させながら引き抜くことにより、ケーシング（７)の下端の撹拌装置（１５）により、土とセメントミルク（１４）が撹拌してアンカー（１）とアンカー（１）の周りの土が、セメントミルク（１４）で固まり、強固なアンカー（１）の埋設が出来ます。 When the anchor (1) is set in the casing (7), the casing (7) is laid on the ground, and an anchor bolt (6) having a length corresponding to the depth of excavation is placed in the casing (7). After connecting (6) and the anchor (1), the anchor (1) is engaged with the attachment (8) for engaging the anchor (1) provided at the lower end of the casing (7).
Then , as shown in FIG. 2, the casing (7) is lifted vertically by the anchor embedding machine (10), and the casing (7) is engaged with the attachment (13) at the lower end of the rotational drive mechanism (12).
Then , the tip of the anchor (1) is brought to the excavation point, and the rotation drive mechanism (12) is rotated, so that the anchor (1) excavates and propels in the ground, and rotates when excavating to the target depth. The rotation of the drive mechanism (12) is stopped.
Then , the engagement between the anchor (1) and the attachment (8) of the casing (7) is disengaged, and the engagement between the lower end attachment (13) and the casing (7) of the rotation drive mechanism (12) is disengaged.
Then , as shown in FIG. 3 , the cement milk (14) , the mortar, or various soil-solidifying materials are poured from the upper end of the casing (7), and the cement milk (14) overflows from the lower end of the casing (7). By pulling out the casing (7) while being rotated by the rotation drive mechanism (12), the soil and the cement milk (14) are stirred by the stirring device (15) at the lower end of the casing (7), and the anchor (1) and the anchor are fixed. The soil around (1) is solidified with cement milk (14), and a strong anchor (1) can be buried.

この発明の効果は、アンカーをケーシングにより、回転、掘削、推進し、目的の深さに定着させます。
そして、ケーシングの上端内よりセメントミルクを流し込みます。セメントミルク等は、ケーシング内を下部へ降りて行き、ケーシングとアンカーとの係合を外した隙間よりケーシング外にあふれ出て、アンカーの周りの土に染み込み、そしてケーシングの外周の土とまざり合い、ケーシングの回転及び撹拌装置の回転により、ケーシングの外周の土とセメントミルクが撹拌され、アンカーと、アンカーの上部の土がセメントミルクにより強固に固定される。 The effect of this invention is that the anchor is rotated, excavated and propelled by the casing, and fixed at the desired depth.
Then , cement milk is poured from the upper end of the casing. Cement milk, etc. descends to the bottom of the casing, overflows the casing from the gap where the casing and the anchor are disengaged, soaks into the soil around the anchor, and collides with the soil on the outer periphery of the casing The rotation of the casing and the rotation of the stirring device stir the soil on the outer periphery of the casing and the cement milk, and the anchor and the soil above the anchor are firmly fixed by the cement milk.

この発明装置を使用することにより、電柱の支線のアンカーが強固になり、電柱の倒れの防止になります。 By using this device, the anchors of the utility poles become stronger and prevent the utility poles from falling.
