Embodiment 1
[0044] Such as figure 1 As shown, a glass fiber anchor rod according to the present invention includes an anchor head 1, two rod bodies 2, a grout plug 4, a backing plate 5 and a nut 6, wherein one end of one rod body 2 is connected to the anchor head 1 One end of the other rod body 2 is connected to the grout stopper 4 and the anchor fitting, and the two rod bodies 2 are connected by a coupling sleeve 7, and the grout stopper 4 is located between the coupling sleeve 7 and the anchor fitting Between, the anchor fittings are a backing plate 5 and a nut 6, the rod body 2 is a hollow structure, the materials of the rod body 2, the grout stopper 4, the backing plate 5 and the nut 6 are all glass fibers, and the rod body 2 The outer wall is a threaded structure, and the rod body 2 is provided with several openings 3, all the openings 3 are evenly distributed on the entire rod body 2, in a quincunx shape, and all the openings 3 are circular in shape and size , and the diameter is 5...
Embodiment 2
[0046] The construction method of a kind of glass fiber anchor rod of the present invention comprises using a kind of glass fiber anchor rod as in embodiment 1, as figure 2 , its construction method includes the following steps:
[0047] Step 1, drilling, drilling on the construction work surface according to the construction plan and measurement setting;
[0048] Step 2: Clear the hole, carry out pressure air cleaning on the drilled hole, and remove cuttings;
[0049] Step 3, install the anchor rod, install the anchor head 1 on one end of the rod body 2, install the grout stopper 4 on the other end and insert it into the hole, so that the rod body 2 is located at the center of the hole;
[0050] Step 4, grouting, using a grouting machine to grout the inside of the rod body 2 until the grouting in the hole is full;
[0051] Step 5, anchoring. After the grouted grout reaches the required strength, install the anchoring accessories.
[0052] First, according to the construct...

Abstract
The invention discloses a glass fiber anchor rod and a construction method. The glass fiber anchor rod comprises an anchor head, a rod body, a stop-grouting plug and an anchor accessory, wherein one end of the rod body is connected with the anchor head, and the other end of the rod body is in sliding connection with the stop-grouting plug and the anchor accessory; the stop-grouting plug is located between the anchor head and the anchor accessory; the rod body is of a hollow structure and is made of glass fibers; and the rod body is provided with a plurality of openings, and the openings communicate with the hollow structure of the rod body. The method comprises the steps of drilling, hole cleaning, installation of the anchor rod, grouting, anchorage and the like. By the adoption of the glass fiber anchor rod and the construction method, the bearing capacity and the tensile capacity of the rod body can be improved advantageously, the construction cost is reduced, a whole installation hole and surrounding cracks can easily be densely filled, and overall strength is improved. By the adoption of the method, the filling effect of grout to surrounding rock cracks can be improved, the grouting compaction degree is increased, the probability of corrosion to the rod body is lowered, the service life is prolonged, construction efficiency is improved, and construction safety is improved.
Description
technical field [0001] The invention relates to the construction field of construction engineering, in particular to a glass fiber anchor rod and a construction method. Background technique [0002] The grades of geological conditions can divide the surrounding rocks into grades I, II, III, IV, V, and VI. For surrounding rocks above grade IV, necessary bolt support is required. When there is a broken zone in the surrounding rock, the surrounding rock Poor stability, unable to form a "stress arch" by itself, easy to collapse, difficult to form a hole, and a potential safety hazard. [0003] When the installation holes of ordinary metal grouting bolts are distributed in the broken zone, because the rock mass in the broken zone is extremely unstable, during the process of installing the bolt, the inner wall of the installation hole is vibrated and the broken rock mass is easily dropped, causing the installation hole to be broken. If there is a blockage in the inner part, once ...
