Fig. 1 show the recyclable Foundation Supported with Composite Soil Nailing scheme of installation of assembled based on anchor cable and soil nailing, peace
For dress order first to manufacture Recyclable anchor rope, arrangement is domatic, and the point position of first row soil nailing node 8 is then set according to construction requirement,
Then node 8 is laid, one end of soil nailing 1 is pierced in domatic through node 8, the termination stayed on domatic is solid with soil nailing anchor head 21
It is fixed, it is here formed as soil nailing termination node 22；Then waist rail 9 is set in second row, anchor cable at regular intervals is reserved on waist rail 9
Hole, domatic bore position is determined according to this anchor cable hole, waist rail 9 is then unloaded, is drilled using drilling machine, drilling depth reaches
Mud off is carried out after it is required that, waist rail 9 is fixed on domatic, is put into anchor cable, slip casting, marginal not slurry side is pulled out Grouting Pipe 24, completed
The recovery of Grouting Pipe 24；One end of precast concrete prestressing force panel 14 equipped with single-layer bidirectional bar-mat reinforcement 17 is passed through into welding
The edge of a wing snapping of barb-shaped sheet metal 16 and waist rail 9, the other end of panel 14 by the angular sheet metal 15 of welding with bolt 13 with
Node 8 connects；Backing plate 18, stepped clamping block 19, the tensioning fixation of anchorage 20 are installed after cement mortar reaches design strength, now formed
Anchor cable termination node 20.Continue to excavate next layer after the completion of this layer of supporting, then supporting construction component is installed, until foundation pit construction
Complete.
The specific make step of anchor cable is as follows：Steel strand wires hole 6, injected hole 7 are reserved with the Inner bolt head 5, by the nothing
Bond steel strand wires 2 and make U-shaped, one end is looped around on semi-circular recesses through the steel strand wires hole 6 on Inner bolt head 5, by Inner bolt head 5 with
Fixed between non-bending steel cable 2 by small steel wire 25；By it is above-mentioned by several adjacent Inner bolt heads 5 on same steel strand wires 2 phase
It is different to angle, it is arranged on the Inner bolt head 5 on top and unobstructed so that steel strand wires 2 can pass through, Grouting Pipe 24 is inserted
In the injected hole 7 reserved on each adjacent Inner bolt head 5, locating support 3 is set along long in the anchoring section of steel strand wires 2, locating support 3 is used
Small steel wire 25 is fixed with steel strand wires 2, the small bundled fixed of steel wire 25 of free segment, and guiding cap 4 is finally installed in anchor cable front end, both complete
Made into Recyclable anchor rope.Locating support is as shown in fig. 7, the Recyclable anchor rope is as shown in Figure 2.
Fig. 3 is new recoverable soil nail 1, and this recoverable soil nail is spin soil nailing, straight using mechanical drilling tool without punching
Connect in the spin soil nailing strength precession soil body, then fix the special anchor head 21 of termination soil nailing；Foundation ditch removes soil nailing when backfilling
Special anchor head 21, circulated using rig opposite direction, soil nailing 1 is extracted, realizes the recycling of soil nailing 1.According to design before construction
Tension, anti-pulling capacity require the soil nailing 1 of selection dimension, and the pull-out test at the scene of carrying out, and determine that soil nailing 1 meets design
It is required that.
It is domatic that the end of the soil nailing 1 by cross node is fixed on foundation ditch, and indent in the middle part of the node, the edge of a wing is in
Cross construction, as shown in Figure 6.
Fig. 4 (a), Fig. 4 (b), Fig. 4 (c), Fig. 5 (a) and Fig. 5 (b) are the view that divides of Recyclable anchor rope Inner bolt head, and Fig. 6 is section
Point plan.
Fig. 7 is anchor cable termination and soil nailing termination way and their positions on domatic.
Connection between channel-section steel waist rail 9 and waist rail 9 is using the method shown in Fig. 8 (a), and 9 be channel-section steel waist rail in Fig. 8 (a), waist
Beam 9 uses channel-section steel, and channel-section steel is connected with the first steel plate 10, the second steel plate 11 by bolt 13.Channel-section steel waist rail 9 connects with prefabricated panel 14
Connect way to be attached according to Fig. 8 (b), one end is led to by the barb-shaped sheet metal 16 and the edge of a wing snapping of waist rail 9, the other end of welding
The angular sheet metal 15 for crossing welding is connected with node 8 with bolt 13.Panel 14 uses precast concrete facade panel, such as Fig. 9 (a), 9
(b), 9 (c), shown in 9 (d) and Figure 10, interior to match somebody with somebody single-layer bidirectional bar-mat reinforcement 17, the both ends prepared screw-bolt hole 12 of panel 14, for
Node 8 connects.Sealant sealing is used between two neighboring panel 14, in the junction of the panel 14 and the waist rail 9,
To possess water-proof function.
After Composition Soil Nailing Walls function terminates, successively successively remove backing plate 18, stepped clamping block 19, anchorage 20, panel 14,
Waist rail 9, node 8, steel strand wires 2, special anchor head 21, soil nailing 1, can so realize recycling.
The shape of bracing of soil nailed wall system is such as schemed in the shape that polylith panel is fixed between a plurality of parallel straight line
Shown in 1.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
