Loop ground anchor device and installation method

Abstract

The invention belongs to the field of construction safety and relates to a loop ground anchor device designed for derrick wind cable anchoring on a construction site. The loop ground anchor device is composed of a ground anchor rod, a loop, an anchor post and a screw cap. The ground anchor rod and the anchor post are connected to form a concentric whole. The ground anchor rod is sleeved with the loop. The screw cap penetrates through the anchor post to be connected with the ground anchor rod. The ground anchor rod is composed of a main rod, a thread and a taper rod. The main rod and the taper rod are connected to form a concentric whole. The thread is turned on the main rod and integrated with the main rod. The loop is composed of a loop head, a blooming loop and a barb. The loop head and the blooming loop are concentrically connected to form a whole; the barb is attached to the loop head and the blooming loop. The anchor post is composed of an anchor post rod and an anchor post hole. The anchor post hole is drilled in the anchor post rod. The loop ground anchor device has the beneficial effect that a derrick wind cable is firmly anchored on rock or concrete.

Description

technical field [0001] The invention relates to a looper ground anchor device, which is designed for the anchorage of a derrick wind rope on a construction site, and belongs to the field of construction safety. Background technique [0002] Due to the high erection of the derrick, it is necessary to set up a wind rope to ensure its stable operation. According to the specification, when the height of the derrick is 15 meters, it is necessary to install the first wind rope. Wind rope; however, the connection between the wind rope and the ground often becomes a weak link. In order to solve the connection problem between the wind rope and the ground, people have designed bundled anchors, drill rod anchors, and spiral anchors to strengthen the wind rope. The connection between the rope and the ground; the so-called bundled ground anchor is to bind the wind rope on the sleeper and bury it in the soil, so that the ground anchor has enough tension on the wind rope.

[0002] Due to the high erection of the derrick, it is necessary to set up a wind rope to ensure its stable operation. According to the specification, when the height of the derrick is 15 meters, it is necessary to install the first wind rope. Wind rope; however, the connection between the wind rope and the ground often becomes a weak link. In order to solve the connection problem between the wind rope and the ground, people have designed bundled anchors, drill rod anchors, and spiral anchors to strengthen the wind rope. The connection between the rope and the ground; the so-called bundled ground anchor is to bind the wind rope on the sleeper and bury it in the soil, so that the ground anchor has enough tension on the wind rope. There is generally no problem in normal conditions, but when encountering special wind loads When the derrick or other load acts, the derrick will collapse due to the insufficient anchoring force of the ground anchor; the so-called drill rod type ground anchor means that the metal rod is inserted obliquely into the ground, and the end is tied with the wind rope. There is generally no problem in normal conditions, but When encountering special wind loads or other loads, the derrick will also collapse due to insufficient anchoring force of the ground anchor; the so-called spiral ground anchor is to install a helical blade on the drill rod of the drill rod type ground anchor, and rotate the helical blade It is a kind of ground anchor to tie the wind rope into the soil. This kind of ground anchor has a strong tie force with the ground, but it is difficult to make
