Detailed description of the invention
As shown in Figure 1 and Figure 2, the present embodiment is a kind of concrete surface plated construction and construction method of applying High-toe wall, this structure comprises heap rock layers 12 below by concrete slab 6, concrete slab, is arranged in the toe board 10 of concrete slab 6 periphery, and excavates along the toe board 10 that massif side slope is arranged the slope, side 9 forming 1:0.5; The toe wall 1 of load retaining wall is set between concrete slab 6 and slope, side 9, and between heap rock layers 12 and concrete slab 6, arranges bitumen sand cushion 11 near toe wall 1 place.
In the present embodiment, toe wall 1 is that bottom outwards expands by concrete slab 6 side and the gradient connected with heap rock layers 12 is the slope of 1:N, N=0.3 ~ 0.7, and the top on slope should ensure connection orthogonal with concrete slab 6 as far as possible; Toe wall 1 is weight platform by side, slope, side 9, and becomes section to be the groove of inverted trapezoidal shape with side domatic, and it is closely knit that this groove adopts rock ballast material 8 to backfill; Toe wall 1 connects with concrete slab 6 in the connecting sewing that formed and is furnished with water-stopping system; Vertical welding dowel 2 on toe wall 1 base foundation reinforcing bar, the arrangement pitch of this dowel 2 is 1 ~ 2m, and the length going deep into basement rock below toe wall is not less than 5m.
As shown in Figure 3, water-stopping system comprises the base copper sealing 3 be embedded in connecting sewing, middle part rubber bar 4, stitches embedded underfill material 5, and is arranged on the surface watertight seal 7 in this connecting sewing top V-type groove; Surface watertight seal 7 comprises the antiseepage protective cover sheet on SR filler in the rubber bar of V-type trench bottom, V-type groove and top layer.
The Specific construction step of the present embodiment is as follows:
A. the anchoring of toe wall 1: toe wall 1 is set between concrete slab 6 and slope, side 9, for guaranteeing the stability of toe wall 1, dowel 2 zygodactyl wall 1 is adopted to carry out anchoring, dowel 2 should be firm with toe wall 1 base foundation reinforcement welding, generally dowel 2 arrangement pitch is 1 ~ 2m, and the length that dowel 2 gos deep into basement rock below toe wall 1 is not less than 5m;
B. the building of toe wall 1: after toe wall 1 base foundation excavation reaches designing requirement, (design size of toe wall 1 should be determined as calculated to carry out concrete pouring construction according to the design size of toe wall 1, during computational analysis, not only to consider that the stress of self is with stable, also should consider the resistance to overturning of toe wall, concrete slab and toe board etc. simultaneously); Toe wall 1 adopts load retaining wall structure, adopts rock ballast material 8 to backfill closely knit, thus add the stability of toe wall and entirety between its weight platform and slope, side 9; Toe wall 1 should ensure orthogonal with concrete slab 6 by the top of piling slope, rock layers 12 1 side as far as possible, thus make both contact and fully stressed, the bottom on slope, face is connect with heap rock layers 12 and the slope outwards expanded, the gradient is 1:N, N=0.3 ~ 0.7, is convenient to the construction rolling of dam material at toe wall position piling rock layers 12;
C. sealing and caulking material filling: arrange bitumen sand cushion 11 near toe wall 1 place above heap rock layers 12, after the construction of this bitumen sand cushion, install base copper sealing 3, middle part rubber bar 4 and stitch embedded underfill material 5 in the connecting sewing that toe wall 1 and concrete slab 6 are formed, the setting of middle part rubber bar 4 is mainly the stop safe water strengthening toe wall 1 site boundary seam;
D. the building of concrete slab 6: carry out building of concrete slab 6 according to the thickness of design, at base copper sealing 3 position, should strengthen vibrating, guarantee the concrete density in sealing position, the construction technology level of site operation personnel should be strengthened simultaneously, ensure the damage that can not cause base copper sealing 3 in construction;
E. surface watertight seal 7 is constructed: arrange surface watertight seal 7 in the top V-type groove of the connecting sewing formed at toe wall 1 and concrete slab 6, and surface watertight seal 7 comprises the antiseepage protective cover sheet etc. on SR filler in the rubber bar of V-type trench bottom, V-type groove, top layer; Wherein the construction of surface watertight seal 7 should be carried out after bottom concrete strength reaches 70% of design strength, full and closely knit in order to ensure SR filler, and SR plug is filled out and should be adopted mechanical execution.
