Embodiment Construction

[0017] Such as figure 1 As shown, figure 1 It is a structural schematic diagram of an anchor rod construction method for civil engineering proposed by the present invention.

[0018] Reference figure 1 , The construction method of an anchor rod for civil engineering proposed by the present invention includes the following steps:

[0019] S1: According to the design spacing of bolts and the actual situation of surrounding rock bedding and joint distribution, mark the eye position with paint;

[0020] S2: Transfer the drill to a predetermined position, level the base of the drill, adjust the angle of the drill rod, and drive the drill bit into the above-mentioned eye position through the drill rod;

[0021] S3: Rotate the drill bit with the drill rod to stir and drill forward. When it is found that the drill is difficult to drill, remove the slag sample in time, distinguish the slag sample, adjust the air pressure and the drilling speed to ensure that the drill bit enters the holding ...

Abstract

The invention provides a construction method for an anchor rod for civil engineering. The construction efficiency is high, mud and vibration are avoided, the stability performance of anchor holes is high, the strength of the anchor rod is high, and the anti-puling bearing capability of the anchor rod is high. The construction method comprises the following steps that an eye position is marked through paint; a drilling machine is moved to the preset position, and a drill bit is driven by a drill rod to drill into the eye position; when it is found that drilling is difficult for the drilling machine, the air pressure and the drilling speed are adjusted in time; in the rotating process of the drill rod, the perpendicularity of the drill rod is observed in real time; after the drill bit drills into the position by the preset depth, whether underground water exists in an anchor hole or not is observed, and when a large amount of underground water exists, clean water is injected in the anchor hole, and when no underground water or a small amount of underground water exists in the anchor hole, cleaning is carried out through an air compressor air pipe; quality detection is carried out on a steel bar, and the steel bar is placed into the bottom of the anchor hole in a manual stacking manner; and a grouting pipe is inserted into the anchor hole, grouting is carried out through a grouting pump and the grouting pipe communicated with the grouting pump, and when the grout reaches the designed height, the grouting pipe is pulled out, and the grout and the steel bar are solidified and form the anchor rod.

Description

Technical field [0001] The invention relates to the field of anchor rod construction, in particular to an anchor rod construction method for civil engineering. Background technique [0002] All the involved buildings are developing towards high-rise, deep, large-area, and heavy-duty. The application of anchor rods in rock-soil reinforcement and support engineering is also increasing and the scope of application is becoming more and more extensive. The innovation or beneficial improvement of this engineering technology field and construction technology method has important engineering significance and economic value. At this stage, the anchor rod construction methods and procedures are relatively cumbersome and the construction efficiency is low. The anchor rod is prone to vibration during the construction process, which affects the stability of the anchor hole. In addition, the anchor rod has low strength and weak pull-out resistance. The above-mentioned problems need to be solv...
