Pipe gallery joint gap waterproof structure and waterproof method prefabricated by pipe-jacking method
The invention provides a pipe gallery joint gap waterproof structure and a waterproof method prefabricated by a pipe-jacking method. The pipe gallery joint gap waterproof structure comprises a water stop steel ring, a connector steel lantern ring, a water swelling water stop glue, a water swelling rubber water stop ring and a liner; the water stop steel ring is arranged on a joint of a first pipejoint in a sleeving mode; the first end of the connector steel lantern ring is arranged on the connector of the first pipe joint in a sleeving mode, and the water stop steel ring is arranged in the connector steel lantern ring in a sleeved mode; the water swelling water stop glue is filled in a gap between the inner side wall of the connector steel lantern ring and the outer side wall of the jointof the first pipe joint; the water swelling rubber water stop ring is arranged on the joint of a second pipe joint in a sleeving mode; and the liner is arranged in the seam between the first pipe joint and the second pipe joint. According to the pipe gallery joint gap waterproof structure and the waterproof method prefabricated by the pipe-jacking method, construction can be synchronously carriedout along with pipe gallery segment prefabrication, and the work efficiency is improved; accumulated errors in the pipe gallery jacking process are eliminated, and the structural strength and the shear resistance are improved; through tongue-and-groove connection, the rainwater permeation path at the joint from outside to inside is prolonged; and after the pipe gallery sections are jacked in place, grouting plugging at the section gaps is facilitated, water leakage of the pipe gallery is effectively prevented, the pipe gallery environment is kept dry, the service life of equipment in the pipegallery is prolonged, maintenance is reduced, and investment is saved.
本发明提出了一种顶管法预制管廊接头缝隙防水结构，包括：止水钢环，套设在第一管节的接头上；接口钢套环，其第一端套设在第一管节的接头上，并将止水钢环套设其中；遇水膨胀止水胶，填充在接口钢套环的内侧壁与第一管节的接头外侧壁之间的缝隙内；遇水膨胀橡胶止水圈，套设在第二管节的接头上；衬垫，设置在第一管节和第二管节之间的接缝内。本发明可随管廊节段预制同步进行，提高工效；消除了管廊顶进过程中的累计误差，提高了结构强度和抗剪性能；通过企口相接，延长了接头处由外而内的雨水渗透路径；在管廊节段顶进就位后，便于节段缝隙处灌浆封堵，有效防止管廊渗漏水，保持管廊环境干燥，提高管廊内设备的使用寿命，减少维修、节约投资。
