Embodiment 1

[0040] A pile plate anchor cable.

[0041] Such as figure 1 As shown, the pile-slab anchor cable of the present invention is composed of an outer anchor head, a free section B, and an anchor section D. The anchor cable has two outer anchor heads of a pile-slab anchor head A and a slope anchor head C. All steel strands The anchorage section is formed through the anchor head C of the slope body. A part of the steel strand is anchored on the anchor head A of the pile plate, and a part of the steel strand is anchored on the anchor head C of the slope body. Through the steel strand wire and each outer anchor head The number of connected bearing bodies can be equal or unequal. There are m bearing bodies connected to the anchor head A of the pile plate, and n bearing bodies connected to the anchor head C of the slope body. The total sum of the two is m +n, where: 1≤m≤4, 1≤n≤10, n≥m, 2≤m+n≤12;

[0042] In this embodiment, the bearing body connected to the anchor head A of the pile p...

Embodiment 2

[0055] A pile plate anchor cable.

[0056] Such as figure 2 As shown, the pile-slab anchor cable is still composed of an outer anchor head, a free section B, and an anchor section D. The anchor cable has two outer anchor heads, the pile-slab anchor head A and the slope body anchor head C. The pile-slab anchor cables are the same; the difference is that the positions of the bearing bodies connected to the pile-slab anchor head A through the steel strands are different. In the pile-slab anchor cables of this embodiment, the The bearing body connected to the anchor head A is the 1st to m ones farthest from the anchor head of the slope in turn, and 1≤m≤4.

Embodiment 3

[0057] Embodiment 3: A construction method using the pile plate anchor cable support and backfill roadbed slope reinforcement technology described in Embodiment 1.

[0058] The construction method includes the following main process:

[0059] (1) Hole making:

[0060] (2) Production and installation of anchor cables: Calculate the length of the steel strands of the anchor cable according to the drilling depth and the structure diagram, remove 10-20cm of PE layer from the end of each steel strand, and thread the longest two steel strands of equal length Pass through the topmost first layer of bearing plate, install the elastic gasket, put the extrusion sleeve on the steel strand close to the elastic gasket, squeeze the extrusion sleeve with a through-core extruder and lock it, and then put the second The second-layer bearing plate is set on the longest two steel strands, and the second longest two equal-length steel strands are inserted into the second-layer bearing plate, and...

Abstract

The invention is pile-plate anchroage cable, including external anchor head, free segment and anchor fixing segment. The cable has slope external anchor head A and pile-plate external anchor head B. The external anchor head comprises clamp piece, anchor plate and backling plate. All the steel strands pass through A to compose the anchor fixing segment; the internal support and the external support 8 is covered on the non-binding steel strand, and there are 2-12 load bearing bodies distributed on the anchor fixing segment and each load-bearing body consists of the steel strand, load bearing plate, spring shim and extrusion cover and these is guide cap on the longest steel strand. The construction method includes the main steps of making holes, making and installing anchorage cable, slip casting, thrice spreading-dragging locking and twice closing the anchor and so on.

Description

Technical field: [0001] The invention relates to an anchor cable for rock-soil anchorage and a construction method of backfill roadbed slope reinforcement technology. Background technique: [0002] At present, in the geotechnical anchoring project——backfill embankment slope reinforcement technology construction, the pressure-concentrated or tension-concentrated ground anchor construction method is mostly used, and the tension-concentrated anchor cable is widely used. Anchored as a whole, all the steel strands of the anchor cable pass through the backfill soil and are anchored on the pile sheet structure supporting the backfill roadbed. The pile sheet bears a large force. Moreover, due to the difference in the physical and mechanical properties of the backfill and the rock and soil, the slope and the backfill are anchored as a whole, and the stress on the slope and the pile is unreasonable, and the force on the two parts is uneven, which is not conducive to the permanent anch...
