The present invention relates to a complete drainage gabion-reinforced soil retaining wall and a construction method thereof, the complete drainage gabion-reinforced soil retaining wall enabling complete drainage by means of forming a front member of the reinforced soil retaining wall by vertically stacking gabion units, and preventing horizontal displacement and breaking of the front member due to the horizontal earth pressure and enabling easy and economical construction by setting one end of a reinforcement in a fixing member between upper and lower gabion units. The complete drainage gabion-reinforced soil retaining wall of the present invention comprises: the front member formed by stacking a plurality of gabion units, having gabion rocks filled inside a metal gabion, so as to come in close contact with one another; backfill soil provided on the back side of the front member; a fixing member which is cast-in-place concrete and covers and integrates the metal gabion of the upper and lower gabion units and the reinforcement on the rear side between the stacked gabion units; and the reinforcement of which one end is set inside the fixing member and the other end is embedded inside the backfill soil.

The present invention relates to: a cast-in-place top pile base, in which a top pile structure is directly formed on an aggregate-tampered layer by using a cast-in-place concrete and all top pile bases can be integrated into one continuous structure, thereby easily enhancing a bearing capacity of a structure base; and a construction method therefor. The cast-in-place top pile base of the present invention comprises: an aggregate-tampered layer laid on the ground and having a plurality of top spaces which are formed at the upper part thereof by a conical space formation member having a wide upper portion and a narrow lower portion, and are identical in shape to the space formation member; an impermeable cover arranged on the inner peripheral surface of each of the top spaces; and a cast-in-place concrete which is cast inside the impermeable cover, wherein the cast-in-place concrete is directly formed, without a space formation member, inside each of the top spaces of the aggregate-tampered layer.

The present invention relates to: a cast-in-place integrated top pile base having a lower pile, wherein the vertical stress in the base is distributed between a lower pile, a top pile, and an upper connecting layer such that the pile base can simultaneously have the advantage of a deep pile that is supported on stratum that is harder than the ground near the surface, and the advantage of a top pile base that minimizes the impact to a building during an earthquake; and a construction method thereof. The cast-in-place integrated top pile base having a lower pile of the present invention includes: a lower pile, which is embedded in the ground and of which the upper end partially protrudes from the ground; an aggregate hardening layer that is spread on the ground to cover the upper portion of the lower pile; and a top pile coupled to the upper portion of the lower pile and provided in the aggregate hardening layer. The top pile has a cone shape having a wide top and narrow bottom and an open top portion, and includes: a stiffener that has a net shape in which net holes are formed to allow the external discharge of a paste-containing portion of the cast-in-place concrete filled therein, the stiffener being disposed on the lower pile and provided in the aggregate hardening layer so that the top surface is exposed above the aggregate hardening layer; a core part that is formed by casting and hardening concrete in the stiffener; and an outer stiffening part that is formed by mixing and hardening the paste-containing portion of the concrete with the aggregate hardening layer disposed outside the stiffener, said portion being a portion that has been discharged to the outside from the stiffener.

The present invention relates to a cast-in-situ reinforcing top pile base and a construction method therefor, the top pile base being capable of directly forming, in a compacted aggregate layer with cast-in-situ concrete, a top pile structure having a wide upper side and a narrow lower side and a reinforced core part and integrating the entire top piles into one continuous structure so as to enable the bearing power of a structure base to be simply and greatly improved. The cast-in-situ reinforcing top pile base of the present invention comprises: the compacted aggregate layer paved on the ground; a plurality of reinforcements provided to be spaced apart from each other in the compacted aggregate layer such that the upper surfaces thereof are exposed on the compacted aggregate layer, and are net-shaped members formed in a cone shape having an open and wide upper side and a narrow lower side, and having meshes formed by crossing a plurality of rows of wire rods; the core part formed by pouring concrete into an inner space of the reinforcement; an outer reinforcing part formed at the outer side of the reinforcement while the concrete poured into the inner space of the reinforcement flows out through the meshes of the reinforcement and is spread and injected into the outer compacted aggregate layer; and leveling concrete provided on the compacted aggregate layer, the reinforcements, and the core part, and poured simultaneously with the concrete for forming the core part and the outer reinforcing part, wherein the total area of the meshes of the reinforcements is greater than 40% of the total area of the reinforcements.
