The present invention discloses a combined support structure and a construction method for a deep buried tunnel in a clastic schist stratum. The combined support structure comprises an advance support, a tunnel steel arch frame and an anchor-sprayed mesh joint support; the advance support comprises a plurality of face fiber anchor rods vertically driven on the face, a plurality of sections of advance small conduit support and a grouting reinforcement area, the plurality of face fiber anchor rods completely cover the face, each section of the advance small conduit support is composed of a plurality of advance small conduits and the overlap length along the tunnel excavation direction is not less than 1m or 1 / 4L 导管 Each section of the advance small pipe support is a plurality of advance small pipes set within 120° on the arch of the tunnel face, and the grouting reinforcement area is the area where the fiber anchor rods and the surrounding rock of the tunnel face in the area where the advance small pipes are set are grouting. The invention effectively ensures the stability of the tunnel face, prevents the excavation face from sliding and collapses, and effectively controls the combined support structure of the support deformation, ensures construction safety, and improves construction efficiency.

The invention discloses a waterproof and drainage construction method for a building foundation pit. The waterproof and drainage construction method comprises the following steps that (1) surveying, setting out and positioning are conducted on a designed foundation pit construction site; (2) a drilling machine is in place, support pile construction is conducted, and a first waterproof structure is formed; (3) constructing a protective layer on the periphery of the first waterproof structure to form a second waterproof structure; (4) foundation pit excavation construction is conducted within the range of the first waterproof structure according to the design drawing, after excavation is completed, top drainage grooves are constructed in the periphery of the top of the foundation pit, and bottom drainage grooves are constructed in the periphery of the inner side of the bottom of the foundation pit; (5) constructing a second drainage well below the bottom of the foundation pit; and (6) waterproof layers are constructed on the bottom face and the inner side face of the foundation pit, and overall waterproof and drainage construction is completed. According to the method, prevention and drainage of accumulated water around the foundation pit are combined, the drainage speed is high, the waterproof effect is good, no accumulated water and water seepage phenomena exist in the foundation pit, the influence of the surrounding accumulated water on the stability of the foundation pit is reduced, the supporting effect on the foundation pit is high, and the safety of the foundation pit is integrally improved.
