Description
Technical Field
The utility model relates to an electric power construction technical field specifically relates to an anchor and construction method of acting as go-between temporarily.
Background
At present, most of temporary stay wires in electric power construction or overhaul adopt a steel chisel or a stay wire coil foundation as anchoring. When encountering the geological condition of soft soil, the steel chisel can not anchor, can not provide enough tension and has great safety risk. The guy plate is a common foundation form of tower guy wires, however, the guy plate foundation has the defects of large foundation pit excavation difficulty, low construction efficiency, poor economy and the like, and can also cause great damage to the ecological environment of a construction site.
Disclosure of Invention
In order to overcome the defects existing in the prior art, the utility model provides a temporary stay wire anchoring device and a construction method. The construction method has the advantages of simple structure, convenience in operation, high construction efficiency, low cost and the like.
The utility model provides an anchor of acting as go-between temporarily, stay wire (4) are connected with the link on main anchor (6) through activity snak link (5), connecting rod A (2) and connecting rod B (3) both ends all set up fixed snak link (1), the link of main anchor (6) and auxiliary anchor A (8) upper end is connected respectively in fixed snak link (1) at connecting rod A (2) both ends, the link of main anchor (6) and auxiliary anchor B (9) upper end is connected respectively in fixed snak link (1) at connecting rod B (3) both ends.
The main anchor (6) and the two auxiliary anchors are arranged in a triangular mode, the included angle between the connecting rod A (2) and the connecting rod B (3) is 45 degrees, the connecting rod A (2) and the connecting rod B (3) are in axial symmetry in the opposite directions of the stay wires (4), the main anchor can disperse a part of force when stressed, the tensile force borne by the whole anchor is increased, the anchor is not easy to separate, and the safety of constructors is greatly guaranteed.
The lower part of the main anchor (6) is provided with a rotary digging mechanism (7), the rotary digging mechanism can be easily screwed into the ground, meanwhile, the contact area between the spiral and soil can be increased, and the anchoring firmness is increased. The rotary digging structure for anchoring the main anchor is only designed with 4 layers, and the pressure above the main anchor can be ensured to be enough after the rotary digging structure is screwed into the ground.
The length of the main anchor (6) and the auxiliary anchor is 160 cm; the pull wire (4) is a steel wire rope;
the construction method of the anchoring device comprises the following steps:
firstly, selecting a proper anchoring position according to topographic and geological features, and determining the installation position of a main anchor (6);
secondly, screwing the main anchor (6) into the ground according to the determined position, determining the installation position of the auxiliary anchor according to the angle and the distance, and nailing the auxiliary anchor into the ground, wherein the distance between the auxiliary anchor and the main anchor (6) is 60-80 cm, the main anchor (6) is 8-10cm higher than the auxiliary anchor, and the included angle between the connecting lines of the two auxiliary anchors and the main anchor is 45 degrees;
thirdly, connecting the main anchor (6) with the auxiliary anchor by using a connecting rod A (2) and a connecting rod B (3), wherein the connecting rod A (2) and the connecting rod B (3) are axisymmetric in the opposite direction of the stay wire (4);
and fourthly, connecting the stay wire with the main anchor.
And (3) effect analysis: in principle, the smaller the angle, the greater the tension, the less easy the ground anchor is to be pulled out, but the smaller the angle, the longer the pull line is needed to fix the electric pole at the same height, the longer the distance is needed, therefore, the smaller angle is usually not selected;
usually according to place characteristic on every side, select suitable position, act as go-between and the contained angle increase on ground, the earth anchor can be corresponding to reducing to the pulling force of acting as go-between, takes place the not hard up danger of earth anchor easily, adopts the utility model provides a device and construction method, vice anchor can share the ascending pulling force in slant that comes from acting as go-between that the main anchor received, all share more including vertical direction and horizontal direction.
And (3) analyzing the pulling force borne by the point A by taking the position of the main anchor as the point A:
F1is perpendicular to= F1×sinα；F1Level of= F1×cosα；
And analyzing the tension force from the connecting rod on the point A:
F2is perpendicular to= F2×sinβ；F2Level of= F2×cosβ
F2 is opposite to F1, therefore, the pulling force from the connecting rod shares the pulling force of A, including horizontal direction and vertical direction.
When the angles α and β are equal to 45 °, the theoretical analysis is optimal, but in practice this is not advisable, and in practice this situation leads to too much stress on the secondary anchor and too little contribution from the primary anchor. Therefore, the optimal state of actual construction is as follows: angle beta < angle alpha < 45 deg.
The main anchor and the auxiliary anchor are distributed in a triangular mode, the included angle between the two connecting rods is 45 degrees, the pulling force applied to the main anchor can be dispersed to two sides, not only can the pulling force be dispersed linearly, but also three ground anchors driven downwards form a three-dimensional stress, and the anchoring effect is enhanced.
The beneficial effects of the utility model reside in that: the design of the main anchor head rotary digging mechanism enables the anchor to be directly screwed into soil, and the anchor is safe and reliable. The main anchor and the two auxiliary anchors are arranged to enable the anchoring to be more stable, and the main anchor is slightly higher than the auxiliary anchors during installation, so that the stress stability is guaranteed. After the installation targets in place, firm reliable compares the anchor disc and can provide bigger pulling force in the region that geological conditions is not good, and the installation is swift simple, can save time greatly, as long as take off the connecting rod of main anchor and vice anchor after the construction finishes simultaneously, the anchor of taking off that just can relax, convenient to carry is little to the environmental destruction. Simple structure also makes the utility model discloses a preparation use cost is low, and economic nature is good.
