Description

Small-section long-slow inclined hole bidirectional excavation multi-winch grading relay conveying device

Technical Field

The application relates to the technical field of engineering construction, in particular to a small-section grading relay conveying device for a plurality of windlasses in bidirectional excavation of long and slow inclined tunnels.

Background

The diversion type hydropower station is more and more favored by the market because of no reservoir submerging loss or small submerging loss due to the fact that a medium-low dam is arranged to form a reservoir, the project amount is relatively small, and the unit cost is usually low. When diversion type hydropower stations adopt tunnels for diversion, in order to obtain an optimal water head, reduce the length of the tunnels and reduce the degree of bends, small-flow mountain rivers generally adopt an inclined tunnel diversion mode. Whether the inclined holes can be safely communicated or not is the basis for success or failure of the whole project, and the excavation and slag discharging efficiency is a key factor for restricting the construction progress. The solution to the excavation construction of the inclined hole mainly comprises: (1) adopting a 'pilot well method + drilling, blasting, expanding and excavating' method or a conventional drilling and blasting method, and enabling the stone slag to slide to the downstream end of the inclined hole by self weight; (2) additionally arranging a construction branch hole to increase a working surface and shorten the material transportation distance, and discharging slag and transporting materials by using a small-sized self-discharging vehicle; (3) and (5) adopting a customized TBM tunneling machine to tunnel and a belt conveyor to discharge slag. At present, the 'pilot shaft method + drilling, blasting, expanding and excavating' method of the gentle dip angle inclined hole is technically difficult to break through the length limit of the inclined hole of 300m, and is only suitable for one-way excavation, the dip angle of a sliding and unloading channel is less than 45 degrees, and the natural channel surface does not have enough flatness, so that the stone slag with different sizes is difficult to slide automatically; the construction branch tunnel needs smaller buried depth and reasonable internal and external traffic conditions, the construction cost is greatly increased, and the air in the tunnel is seriously polluted by transportation of a dump truck when the road gradient exceeds 15%; the third scheme needs investment of huge purchase equipment and training, the time consumption is long, the third scheme can only be used in the excavation stage, and the investment equipment cannot serve for subsequent transportation work.

The head sheave is a pulley which is positioned in the center of the main rail and is tightly suspended on the tunnel roof.

And a lower tunneling first winch U21 rewinds the steel wire rope, a lower tunneling full-slag heavy truck U4 is dragged to transport the stone slag upwards along a lower tunneling main rail U71, the stone slag reaches a discharging conversion platform at the upstream end, the stone slag is turned over to a lower tunneling dump truck U80, and the dump truck transports the stone slag to an out-of-tunnel slag discharging point. And the transportation operation is repeated until the excavation of the lower tunneling second auxiliary hole U12 and the lower tunneling second staggered hole U32 is completed, namely the excavation of the U1 section of the inclined hole is completed. The positions of the lower tunneling second auxiliary hole U12 and the lower tunneling second staggered hole U32 depend on the limit length of a steel wire rope of the lower tunneling first winch U21 after the safety turns of the winding drum are met.

The functions of the lower tunneling second winch U22, the winches U23 and … … are similar to that of the lower tunneling first winch U21, and the subsequent description is omitted.

3. Before the lower tunneling second winch U22 lifts the lower tunneling full-slag heavy vehicle U4 to the position of the lower tunneling locking anchor pile U62, the lower tunneling first winch U21 is used for sliding the empty vehicle U41 to be loaded with slag to the lower tunneling second staggered tunnel U32, and the lower tunneling second winch U22 and the lower tunneling first winch U21 are relayed to complete the excavation of the U2 section of the inclined tunnel.

And a locking anchor pile D61 is arranged at a position about 2m downstream of the head sheave D81 and serves as a temporary fixing point of the full slag truck when the first tunneling winch D21 and the second tunneling winch D22 are in relay. The locking anchor pile D63 has the same function as the locking anchor pile D61, and the excavation of the deviated hole D31 and the auxiliary hole D13 is completed through repeated relay operation of the second hoisting machine D22 and the first hoisting machine D21, so that the excavation of the inclined hole D1-2 section is completed.

Similarly, the inclined hole excavation is completed in a manner that the winding engine is added or transferred in stages according to the embodiment 1 and the embodiment 2 until the inclined hole excavation is completed.

Referring to the attached figure 4, the concrete way of meeting relay between a full slag heavy vehicle and an empty vehicle to be charged is as follows:
