Prefabricated comprehensive pipe gallery joint waterproof connecting structure
The invention discloses a prefabricated comprehensive pipe gallery joint waterproof connecting structure. The joint waterproof connecting structure comprises an inner sealing rubber strip groove, an outer sealing rubber strip groove, a grouting groove, a grouting hole, exhaust grooves, a prestress tensioning anchorage body and prestress tendons. For one end face of a pipe gallery, the inner edge and the outer edge of the end face are provided with an inner chamfered edge and an outer chamfered edge respectively. After two adjacent pipe galleries are spliced, the spliced portions of the two outer chamfered edges and the two inner chamfered edges are filled with mortar or sealant for smoothing, the two inner sealing rubber strip grooves and the two outer sealing rubber strip grooves are provided with water-swelling water stopping strips, and a grouting cavity formed by splicing the two grouting grooves is internally provided with an annular inflatable rubber ring or filled with concrete.According to the structure, sealing is achieved through smoothing of the inner and outer chamfered edges, sealing of the two water-swelling water stopping strips and concrete grouting of the groutingcavities, five waterproof sealing structures can be formed at the joint part of the pipe gallery from outside to inside, the waterproof and water-stopping effects are good, connection is firm, the service life is long, and the installation is convenient.
本发明公开了一种预制综合管廊接头防水连接结构，该接头防水连接结构包括内密封胶条槽、外密封胶条槽、灌浆槽、注浆孔、排气槽、预应力张拉锚固体和预应力筋，对于管廊的其中一个端面而言，该端面的内边缘和外边缘分别设置内倒角边和外倒角边；相邻两管廊拼接后，两外倒角边和两内倒角边的拼接处均填充砂浆或密封胶来抹平，并且两内密封胶条槽和两外密封胶条槽设置遇水膨胀止水条，两灌浆槽拼合成的灌浆腔内设置有环形的可充气橡胶圈或灌注混凝土。本发明通过内、外倒角边抹平、两道遇水膨胀止水条密封及灌浆腔灌注混凝土来进行密封，在管廊的接头部位由外至内共可形成五道防水密封构造，防水、止水效果好、连接牢固、使用寿命长、安装便捷。
