And in the excavation process of the exploration flat tunnel on the same layer, all the generated tunnel slag is firstly transported to the corresponding slag outlet 3 in the tunnel slag outlet for slag discharge. More specifically, the excavation sequence of each layer of exploration open cut is different according to the different arrangement modes of the slag hole openings 3; referring to the arrangement shown in fig. 4 to 6, the excavation sequence can be performed along the direction of the arrows shown in fig. 4 to 6 for different selected positions of the slag hole 3, and the corresponding conveying direction of the hole slag inside the hole slag is opposite to the direction of the arrows in the drawings. For example, taking the example shown in fig. 4, the slag hole 3 is excavated into the side slope from the position, when the slag hole is excavated to the position connected with the down-the-river adit 1, the slag hole can be continuously excavated towards both ends along the direction of the down-the-river adit 1, when the slag hole is excavated to the position connected with a certain cross-river adit 2 along the direction of the down-the-river adit 1, the cross-river adit 2 is excavated, and in order to ensure that the ventilation effect of the whole-layer exploration adit is good, one end of the cross-river adit 2 can be directly penetrated from the surface of the side slope to form the hole, thereby facilitating ventilation.
Additionally, because the utility model discloses in set up the slag notch 3 of each layer exploration concora crush into the setting of staggering of the incline direction along the side slope, can avoid the influence of different layers exploration concora crush excavation construction like this, consequently in the above-mentioned step two of construction method, can carry out the construction of different layers exploration concora crush simultaneously. The hole slag of each layer of exploration flat hole is transported out from different positions in the inclination direction of the side slope, so that the influence of the slag discharge of the upper layer of exploration flat hole on the slag discharge of the lower layer of exploration flat hole and other constructions is avoided, the construction efficiency can be further improved, and the construction period is shortened.
More specifically, in the third step of the construction method, if the down-the-river adit 1 is short, the ventilation effect of the whole exploration adit can be ensured, so that theoretically, the down-the-river adit 2 can be excavated and constructed in the same layer of exploration adit 1 after the construction of the down-the-river adit 1 is completed; or the excavation construction of the horizontal river flat tunnel 2 and the further excavation construction of the horizontal river flat tunnel 1 can be simultaneously carried out after the horizontal river flat tunnel 1 is excavated to the position communicated with the corresponding horizontal river flat tunnel 2 along the direction.
