Problems solved by technology

[0017] 1. It is difficult to collect the pullout force of each soil layer directly, and the cost is quite high;
[0018] 2. Through drilling, that is, indirect production of steel bars or steel hinge wire bolts, you must wait for a long time. Adding some early-strength agents to make them early-strength will make the heat of hydration too concentrated, making them The inner slurry, water, soil layer, etc. all suddenly heat up and expand greatly, and then shrink due to cooling after hydration, thus weakening the pullout resistance of the formed anchor rod and reducing its reliability and stability

Embodiment Construction

[0042] Below in conjunction with the preferred embodiment shown in accompanying drawing, be described in further detail:

[0043] In the accompanying drawings of the present invention, figure 2 Reference numerals 21, 23, 24, and 25 in the figure are respectively plastic pipes, anchor clamps, anchor tendons, and grouting anchor rods.

[0044] In all drawings, Lf is the free segment, and Lm is the anchor segment.

[0045] image 3 Reference numeral 31 in is the soil layer.

[0046] Figure 4 The reference numerals 42, 43, 44 in are steel bars, steel strands, and center lines respectively, while the reference numeral 41 may be a steel pipe.

[0047] Figure 5 Reference numeral 51 in is the top end of the anchor rod steel pipe.

[0048] The technical problem to be solved by the present invention is to avoid the disadvantages of the above-mentioned prior art and propose a bolt and its rapid construction method.

[0049] Such as figure 1 As shown, it is basically the same a...

Abstract

The invention relates to an anchor quick construction method using steel tube as the anchor bar. The method includes that a hole is prepared in the soil and the jointed steel tube is inserted into the hole; grout is injected through the steel tube hole and stopped when overflowing the anchor hole or the predetermined position; a waist beam is spanned or the anchor is locked firmly on the waist beam by nuts after short time maintenance. With the method of the invention, the anchor bar is tensioned in resistance of drawing after satisfying the corresponding conditions, thereby the time waiting for the anchor bar construction in the side slopes and foundation ditches supporting process is greatly shortened and the construction period is also shortened.

Description

technical field [0001] The invention relates to a construction method in building engineering side slope or foundation pit support, and more specifically relates to a soil layer anchor rod and a rapid construction method thereof. Background technique [0002] The names of soil anchors and rock anchors are similar, but their core purposes and functions are very different. The soil anchors provide pullout resistance for foundation pit or slope support, mostly in the horizontal direction. When the rock formation is relatively complete, it will Stable and safe, so the rock bolt is mainly used to strengthen the cracks, broken zones and weak layers in the rock formation by grouting, so as to realize the stability of the rock mass itself. Appropriately bear the corresponding load, especially the main purpose of the hollow bolt in the rock mass layer is to realize its grouting reinforcement. It is the same bolt, the purpose and function of the soil layer and the rock body are very d...
