Problems solved by technology

Once the landslide disaster is triggered by the earthquake, it will directly block traffic, destroy buildings, and form a barrier lake, causing heavy casualties and property losses
[0003] Today's slope reinforcement technology is mainly based on the traditional rigid support method, which is widely used and has a good reinforcement effect in non-seismic areas, but there are the following problems in earthquake action: 1. The support system is too rigid, and the internal accumulation of the slope under earthquake action The energy cannot be released, and it is easy to cause brittle failure of the support system and landslides; 2. The internal force of the anchor increases sharply under the action of the earthquake and the rigidity of the anchor cap is too large, which can easily cause the anchor to be damaged or the anchor cap to be crushed, causing the anchor to collapse. Anchorage failure; 3. It is difficult to judge the damage of the structure itself with the existing support technology, especially after the earthquake, the support structure looks good but the internal damage is serious, the support capacity is lost, and there are great safety hazards

Embodiment 1

[0042] like Figure 1-8 As shown in the figure, a support method for an intelligentized seismic-resistant rubber concrete flexible support structure for a slope, the intelligentized seismic-resistant rubber-concrete flexible supporting structure for a slope includes a seismic flexible support structure 1 for a side slope and an intelligent monitoring of the flexible support structure. System 2 ; the slope seismic flexible support structure 1 includes a flexible concrete support frame 3 and a seismic bolt 4 .

[0043] The anti-seismic anchor rod 4 includes an anchor head and a rod body 45, the anchor head includes an anchor 41, a backing plate 43, a protective shell 44 and an anti-vibration device 42 located on the backing plate 43, and the anti-vibration device 42 includes a self-aligning roller Bearing 421, arc-shaped limb claws 422 and spherical base 423, the spherical roller bearing 421 is a high-stress spherical roller bearing that can bear axial load, the inner edge of th...

Embodiment 2

[0058] The construction method of the intelligentized slope anti-seismic rubber concrete flexible support structure is the same as that of Embodiment 1. Further, the number of the rod bodies 45 is 3, but in step 5, when the bolt is synchronously tensioned and locked, due to the construction technology or construction Due to the influence of quality, there is a small difference in the prestress loss of each rod body 45 during prestress tensioning or locking, resulting in unbalanced prestress on each rod body 45, such as Figure 9 As shown, when the prestress of the rod body 45 is unbalanced, the anchor 41 is slightly inverted, and one end of the larger prestressed rod body 45 sinks, realizing partial prestress release, while one end of the smaller prestressed rod body 45 is lifted, which is equivalent to applying Part of the prestress is removed, and when the prestress of the rod bodies 45 on both sides is the same, the anchor 41 will no longer be turned over, and a new state of...

Abstract

The invention discloses a support method for an intelligent slope anti-seismic rubber concrete flexible support structure. The intelligent slope anti-seismic rubber concrete flexible support structure includes a slope anti-seismic flexible support structure and an intelligent monitoring system for the flexible support structure. The anti-seismic flexible support structure of the slope includes a flexible concrete support frame and an anti-seismic anchor. Supporting methods include: 1 slope repair; 2 stakeout; 3 bolt construction; 4 support frame construction; 5 installation of anchor head, tensioning and locking of anchor bolts; The invention effectively solves the problems that under the action of an earthquake, the traditional rigid support structure cannot release energy, is prone to brittle failure, the anchor rod in the rigid support system is damaged or fails to anchor, and the damage of the support system after the earthquake cannot be evaluated. Provided is an intelligent anti-seismic rubber concrete flexible support method for slopes with advanced anti-seismic concept, excellent anti-seismic performance, and self-monitoring and self-inspection functions, which has broad application prospects and significant economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of slope reinforcement, and in particular relates to a support method for an intelligent anti-seismic rubber concrete flexible support structure for a slope. Background technique [0002] my country is a country with frequent earthquake disasters. According to statistics, the average number of earthquakes of magnitude 5 or above in mainland my country is as high as 20 each year, and these moderate and strong earthquake areas are widely distributed in various slopes, including railway slopes, highway side slopes. slopes, water conservancy slopes, etc. Once the earthquake action triggers the landslide disaster, it will directly block traffic, destroy buildings, and form a dammed lake, causing heavy casualties and property losses. [0003] The current slope reinforcement technology is mainly based on the traditional rigid support method, which is widely used and has good reinforcement effect in non-seismic area...
