Abstract:
PURPOSE: A backfill reinforcement structure of a stiff structure and a construction method thereof are provided to improve the confining pressure about a connection unit by unifying a stiff structure and a connection unit constructed in the back side. CONSTITUTION: A construction method of a backfill reinforcement structure of a stiff structure(30) is composed of the steps of forming an earthwork part(10) in the back side of the location in which the stiff structure is constructed. The earthwork part induces the lineal settlement. A reinforcing member(22) is installed in the front of the earthwork part. The reinforcing member includes a vertical unit and a horizontal unit. The vertical unit is contacted to the back side of the stiff structure. A geotextile(23) is installed on the horizontal unit of the reinforcing member. A connection unit layer(21) is formed by filling up in the upper side of the geotextile with a filler(24).

PURPOSE: A railway reinforced roadbed thickness computing apparatus pressing a packer with fluid pressure is provided to perform water-tightly inspection of a conduit line using correlation of the amount of leakage and air pressure change amount. CONSTITUTION: A railway reinforced roadbed thickness computing apparatus pressing a packer with fluid pressure comprises a packer apparatus, a pressure sensor(20), a signal conversion amplifier(30), a MICOM and a monitor(50). The packer apparatus pressurizes packer by using the fluid pressure and supplies the compressed air to a water-tightly inspection section of a conduit line. The pressure sensor senses the air pressure change of the water-tightly inspection section of the conduit line. The MICOM analyzes the air pressure change amount sensing signal outputted from the pressure sensor. The MICOM outputs the analyzed information in the monitor.

Abstract:
A surface connection type precast reinforced roadbed rigid wall structure and a method for constructing the same are provided to induce the integration of a reinforced roadbed rigid wall and an embankment and to form a load transmission structure by connecting precast concrete panels (PC panels) and backfilling material by a surface connection method and by injecting filling material between the reinforced roadbed rigid wall and the embankment, and are also provided to easily stack the precast concrete panels into the reinforced roadbed rigid wall with flexural rigidity by continuously arranging the reinforcing bars of the reinforced roadbed rigid wall using the flat ducts formed inside the precast concrete panels. The surface connection type precast reinforced roadbed rigid wall structure comprises: the embankment; a foundation part buried in the ground and having a foundation part protruding reinforcing bars vertically formed in the same; a reference frame having a reference connecting plate, used as a welded metal mesh installed when the embankment is formed, preventing verticality and soil leakage on a slope having a severe gradient, and installed to secure the stability of the embankment under and after construction; the precast concrete panels having the flat ducts and embedded plates, assembled to be stacked each other, and forming the reinforced roadbed rigid wall; and the filling material injected between the reinforced roadbed rigid wall and the embankment, wherein the precast concrete panels are connected to the reference frame by the surface connection method.
