Open cut cable tunnel sealing structure suitable for large deformation and construction method
According to the cable tunnel sealing structure suitable for large deformation, the geomembrane laid on the outer side of the connector of the cable tunnel body is used for sealing and water stopping, the extension belt pre-buried in the joint is used for bearing external loads, and the inner side of the geomembrane is prevented from being disengaged and damaged; therefore, the cable tunnel interface can be effectively sealed and water can be effectively stopped under the condition of large deformation of the cable tunnel interface. The invention further provides a construction method of the cable tunnel sealing structure suitable for large deformation, after a groove allowing the geomembrane to penetrate through is excavated below the connector position of the cable tunnel, the cable tunnel is poured, the extension belt is pre-buried in the joint in the circumferential direction of the cross section of the cable tunnel, the joint is filled with the filler, and the cable tunnel is formed. According to the method, the geomembrane is laid on the outer side of the connector of the cable tunnel and fixed, finally, grouting filling is conducted on the groove, the cable tunnel connector sealing structure suitable for large deformation can be formed, and therefore the leakage phenomenon caused by large deformation of the cable tunnel connector is effectively avoided.
本发明提出一种适用于大变形的电缆隧道密封结构，使用敷设在电缆隧道本体接口外侧的土工膜进行密封止水，并通过预埋在接缝内的延展带承受外部荷载，防止土工膜内侧发生脱空破坏，从而能够在电缆隧道接口发生大变形的情况下有效密封止水；本发明还提供一种适用于大变形的电缆隧道密封结构的施工方法，在电缆隧道接口位置下方开挖用于使土工膜穿过的沟槽后，浇筑电缆隧道，将延展带沿电缆隧道的横截面周向预埋在接缝内，并在接缝内填充填料，在电缆隧道的接口外侧敷设土工膜并固定，最后对沟槽进行灌浆填充，该方法能够形成适用于大变形的电缆隧道接口密封结构，从而有效避免电缆隧道接口因大变形而产生的渗漏现象。
