Technical field
The present invention relates to a kind of subterranean wall that is suitable for offal treatment field, building, road retaining wall etc. needs the manufacture method of steel plate wall in the place of water proof.
Background technology
In interim embankment when retaining wall in the construction of underground structure and waters, bay Facilities Construction etc., adopt steel sheet pile more.Its reason is that the high rigidity body of wall that utilizes this high quality material of steel to make except that can building up, also has better water-resisting property in the short construction period.
Though the steel of steel sheet pile main body self not water flowing fully certainly,, under chimerism, because the gap portion that exists in connector portions passes through water, so there is very big influence in the gap of this blank area to the water-resisting property of steel sheet pile.
Generally speaking, even the connector portions after squeezing under than the state that is easier to water flowing, after a while, because grogs etc. are blocked in joint inside with current, also can improve water-resisting property.But, in the time can not expecting that packed joint such as grogs is inner, and, also considering a kind of scheme that as far as possible reduces the gap of this joint inside in order further to improve water-resisting property.
But,, exist in the very large problem of driving resistance of blank area if the gap is too small, because water-resisting property and application property are conflicting performance requirements, so, can not reduce the gap of blank area entirely or increase the gap, and the water-resisting property that how to improve connector portions is a big problem.
For example, the water proof method as in the past offal treatment field etc. has when adopting steel sheet-pile wall, is reaching the last, and applies the dilatancy water proof material of ormal weight in connector portions, after squeezing into, utilizes the method for this water proof material because of water proofs that expands such as seawater.
In addition, in Japanese publication communique 2001-026925 (patent documentation 1), put down in writing a kind of " core wall ", as shown in figure 45, by welding the joint 62 of a plurality of U font steel sheet piles 61, form the core wall constituting body 63 of one, on one side the joint 64 of chimeric this side edge to each other, on one side a plurality of core wall constituting bodies 63 connected be arranged in the ground, simultaneously, around the core wall constituting body 63 that adjoins each other joint 64 to each other, implement foundation improvement 65.
In addition, in Japanese publication communique 07-324329 (patent documentation 2), put down in writing the method for a kind of " utilizing the construction method of the core wall of steel pipe colonnade ", as shown in figure 46, one side's the female joint material 73 of the joint of steel pipe sheet pile 71 is set, at a pair of alar part 74, the outward extending edge 75a of portion is set on the side's alar part 75 in 75, link a plurality of these steel pipe sheet piles 71 by mutual chimeric male joint material 72 and female joint material 73, after forming the steel pipe plate piling wall, excavate the ground of constructing side one side of building, expose connector portions, by welding 76, the front end of the 75a of edge portion of female joint material 73 is connected waterproofly the steel pipe external side of main body face of the other side's steel pipe sheet pile 71.
In addition, as technology in the past, the invention of putting down in writing is arranged in the open communique 01-168766 of Japan Patent, the open communique 2000-192446 of Japan Patent, the open communique 2000-192451 of Japan Patent, the open communique 2000-073361 of Japan Patent, the open communique 2000-234330 of Japan Patent, the open communique 2001-214435 of Japan Patent, the open communique 2001-248152 of Japan Patent, the open communique 2002-146772 of Japan Patent.
In the steel plate wall that construction is made of steel sheet pile etc., adopt the method for dilatancy water proof material to be subjected to the environmental safety of dilatancy water proof material self and the restriction of durability, simultaneously, when from the coating of steel sheet pile etc. or installation, to steel sheet pile etc. squeeze into during when longer, worry that the water proof material expands because of rain or dew, moisture etc., make squeezing into of steel sheet pile etc. bothersome, or the water proof material peels off when squeezing into steel sheet pile, or because of the heat charing etc., this just needs to confirm the water-resisting property of the core wall that forms.
At this moment, for example, need to check whether flow out water from the offal treatment field side direction core wall outside, or for guaranteeing abundant water-resisting property, and need improve leakage area ground on every side etc. in the not so good part of water proof, also there is the problem that can not erase the uneasy sense of leaking in this except that increasing man-hour and prolonging the duration.
And when adopting U shaped steel sheet pile, because the water proof material is positioned at the neutral axis place, cross section that connects steel sheet-pile wall, in work progress, the water proof material produces the dislocation repeatedly that the dislocation shearing force causes because of being subjected to wave external force, worries to destroy the water proof material.
In addition, in the invention of in the open communique 2001-026925 (patent documentation 1) of Japan Patent, putting down in writing, except that heavy-duty machinery and instrument that the weight of selecting with incorporate core wall constituting body 63 is complementary, also need near the joint 64 by core wall constituting body 63 foundation improvements 65 to guarantee water-resisting property and guarantee to be used for the environmental safety of the material of foundation improvement.
In addition, in the invention of Japanese publication communique 07-324329 (patent documentation 2) record, the butt joint head welds, but owing to be that water proof with respect to building is the phreatic water proof of ground, so be different from water proof with respect to offal treatment field etc., as long as the degree of water-resisting property is the degree for being complementary with the drainage of common building side setting, and the objective of the invention is to seek higher water-resisting property and reliable function is inequality.
