Grouting method using rift pack in construction of underground continuous wall

摘要

The invention thumb pile and jibogong of the installed lift the clearance of the check valve internal inlet to occur between the wale pack material files and the wale and stretching by providing the (RIFT PACK) in the gap and enforce the cement grouting method as construction the toryubyeok rigidly binding and so as to lift pack to fill the concrete pre-cast in the space portion of the H section steel in the wale of the H beams so that the foot hold the ring is installed to the lift pack so as to be securely fixed thereto buried strap to wale receiving the earth pressure of the side wall to provide a grouting method using the lift-pack in toryubyeok construction that allow smoothly pass the horizontal load of the file in the re-wale and stretching.; Grouting method using the lift-pack in toryubyeok construction according to the present invention comprises the steps of irradiating the gap size of the construction site of the construction target toryubyeok; Determining the type and specification of the lift pack for grouting, depending on the size of the survey niche; Installing determined grouting lift pack for grouting in the construction site and step making a loop in wale; Injecting a grouting material through the inlet check valve is built in the installed lift pack; After completion of the injection in accordance with a predetermined time grout material lift pack is sealed automatically by a check valve comprising: curing for a predetermined time; And it is configured to include the steps of: installing a pre-cast concrete to the space portion of the strip-shaped steel H artisan.; Thus, according as the present invention, the soil, and by using a constant magnitude lift pack manufactured to meet a wide range of field conditions, such as the gap size it underwent grouting, workability is simple, cost-effective and to maintain the structural stability there is an advantage in that.
