白蚁屏障密封
摘要：
在此披露一种白蚁屏障密封，包括：一个空心密封本体，该空心密封本体具有环绕从一个插入末端延伸到一个表面末端的一个轴向钻孔的一个壁；一个闭合形成物，该闭合形成物围绕该表面末端用于与一个闭合件接合；该闭合件，用于当与该闭合形成物接合时闭合在该密封本体的该表面末端处的该钻孔的孔口；单向阀门装置，该单向阀门装置位于该插入末端处或围绕该插入末端，或介于该密封本体的该插入末端与该表面末端之间，这个单向阀门装置被安排成允许液体穿过该轴向钻孔从该表面末端流动到该插入末端，但是防止液体穿过该轴向钻孔从该插入末端流动到该表面末端；外部密封装置，该外部密封装置围绕该密封本体的该壁的一个外表面，用于使该密封本体的该壁相对于钻穿一个混凝土板的一个孔的内表面密封；以及内部密封装置，该内部密封装置围绕该密封本体的该壁的一个内表面，用于当一个注射器被插入到该密封本体的该钻孔中时使该密封本体的该壁相对于该注射器的一个外面密封。
摘要（英）：

A termite barrier seal including: a hollow seal body having a wall surrounding an axial bore extending from an insertion end to a surface end; a closure formation about the surface end for engagement with a closure; the closure for closing the orifice of the bore at the surface end of the seal body when engaged with the closure formation; one-way valving means at or about the insertion or intermediate the insertion end and the surface end of the seal body, the one-way valve means being arranged to permit liquid flow through the axial bore from the surface end to the insertion end, but to prevent liquid flow through the axial bore from the insertion end to the surface end; external seal means about an external surface of the wall of the seal body for sealing the wall of the seal body against the internal surface of a hole drilled through a concrete slab; and internal seal means about an internal surface of the wall of the seal body for sealing the wall of the seal body against an external face of an injector when inserted into the bore of the seal body.
