Construction adit with bifurcation tunnel
The invention discloses a construction adit with the bifurcation tunnel. The construction adit comprises a construction adit body and a bifurcation tunnel body, wherein the construction adit body comprises a skew tunnel section, an adit section, a plugging section and a low tunnel portal; and the bifurcation tunnel body comprises a skew tunnel section, an adit section and a high tunnel portal. Oneend of the construction adit body is connected with a water conveyance tunnel, and the other end of the construction adit body is an outlet, namely the low tunnel portal, and the low tunnel portal communicates with a ground surface connecting road. One end of the bifurcation tunnel body is connected with the construction adit body, the other end of the bifurcation tunnel body is an outlet, namelythe high tunnel portal, and the elevation of the high tunnel portal is higher than the highest water level possibly reached in the water conveyance tunnel. And the bifurcation tunnel body is connected with the construction adit body at the adit section. The construction adit is high in utilization efficiency and good in terrain adaptability, the high tunnel portal of the bifurcation tunnel can beused as a surge shaft in the operation period and a access tunnel in the overhaul period, the low tunnel portal is used for deslagging and drainage in the construction period, and the requirement forconstruction convenience can be met.
本发明一种带岔洞的施工支洞，包括施工支洞、岔洞，所述施工支洞包括斜洞段、平洞段、封堵段和低洞口；所述岔洞包括斜洞段、平洞段和高洞口。所述施工支洞一端连接输水隧洞，另一端为其出口即低洞口，低洞口与地表连接道路连通。所述岔洞一端连接施工支洞，另一端为其出口即高洞口，高洞口的高程高于输水隧洞内可能达到的最高水位。所述岔洞与施工支洞在平洞段连接。本发明施工支洞利用效率高、地形适应能力强，岔洞高洞口可满足运行期作为调压井及检修期检修交通洞通道的要求，施工期低洞口用于出渣及排水，可兼顾施工便利要求。
