The specific use mode and function of the embodiment are as follows:

when the device is used, 1, the slide-resistant pile 102 is constructed: excavating the anti-slide pile 102 by subsection jump holes, sealing the bottom in time after the excavation is in place to prevent a foundation bearing layer from being damaged, constructing the support pile 101 and the anti-slide pile 102 at the same time, pouring concrete to a position 14m above the road pavement elevation, and constructing the upper part when horizontal support construction is carried out; two difficulties exist in pile foundation construction:

constructing an ultra-close pile foundation, wherein the minimum distance between a support pile 101 and an anti-slide pile 102 is 0.3cm, the minimum distance between the anti-slide pile 102 is 1m, the support pile 101 and the anti-slide pile 102 are in a finished product shape, and the construction process adopts a jumping excavation mode of firstly lengthening, then shortening, firstly enlarging, then reducing and separating holes, namely firstly constructing the anti-slide pile 102, then jumping excavation construction, then constructing an adjacent anti-slide pile 102, and finally constructing the support pile 101, so that the construction safety and the pile forming quality are ensured;

and secondly, constructing an overlength half pile, wherein the supporting pile 101 is only constructed to the position with the pavement elevation of 14m, a longer empty pile exists in the supporting pile 101, the maximum empty pile length is more than 10m, and the elevation of the pile top is controlled by adopting a pressure sensor on the engineering site, so that the effective pile length and the over-poured concrete amount are ensured.

2. And (3) side slope support construction: slope excavation, anchor cables 202 and inter-pile plates are alternately and circularly performed, the grading height is 0.5m below the anchor cables 202, and next-level slope excavation can be performed after the anchor cables 202 are supported; the anchor cable 202 adopts pressure grouting, the prestressed anchor cable 202 tensioning can be carried out after the strength of cement mortar reaches 85 percent, and the prestressed anchor cable 202 tensioning is carried out according to secondary four-level cluster tensioning; before the side slope is excavated to the road surface elevation, all anchor cables 202 are not required to be anchored; after the slope excavation is finished, unified anchor sealing can be carried out; in the construction and operation period of the side slope, the internal force of the anchor cable 202 is monitored regularly, and abnormal conditions are found and fed back in time

3. Internal stay, couple roof beam, waist rail 301, stand construction: when the road surface is excavated to the position with the elevation of 14m, the excavation operation is suspended, the first inner support, the longitudinal connecting beam, the upright post, the oblique beam, the waist beam 301 and the second inner support are constructed, a special construction scheme is compiled before construction, and expert demonstration is organized, so that the lower slope construction can be carried out when the strength of the member reaches more than 90% of the design strength.

The construction technology of the vertical high slope pile anchor and internal support composite system comprises the following process flows: surveying and paying off → field leveling → construction of slope top water intercepting ditch → anti-slide pile 102 and support pile 101 construction → crown beam construction → excavation of earth and stone (layering, 50cm below anchor rope 202) above 14m of road surface elevation → construction of anchor rope 202 → construction of inter-pile plate → excavation, anchor rope 202 and inter-pile plate are circularly constructed to 14m above road surface elevation → construction of inner support, connecting beam, waist beam 301, column construction of second (top) inner support, connecting beam, waist beam 301 and column construction → excavation of earth and stone below 14m of road surface elevation → construction of inter-pile plate (excavation and alternate construction of inter-pile plate).
