Abstract
The utility model relates to a kind of for the shaft structure of slagging tap in Excavation of High And Steep Slopes engineering.The purpose of this utility model is to provide a kind of for the shaft structure of slagging tap in Excavation of High And Steep Slopes engineering, is intended to the problem solving difficult deslagging in high gradient slope construction, the mode of slagging tap is fixed relatively, reduces and other mutual interference of constructing.The technical solution of the utility model is: a kind of for the shaft structure of slagging tap in Excavation of High And Steep Slopes engineering, comprise the drainage tunnel that high gradient slope is close with the some layers of lower planes position be arranged in this side slope, it is characterized in that: at the deslagging vertical shaft of a periphery up/down perforation of described each layer drainage tunnel, this silo bottom is provided with hole of slagging tap; Described deslagging vertical shaft is connected hole with arranging between drainage tunnel, and this connection is propped up slagging tray smooth connection the utility model excavate near the employing oblique angle, side of deslagging vertical shaft in hole and is applicable to hydroelectric project.
Description
Technical field
The utility model relates to a kind of for the shaft structure of slagging tap in Excavation of High And Steep Slopes engineering, is applicable to hydroelectric project.
Background technology
In hydroelectric project, often run into high gradient slope, in design, normal employing arranges multilayer drainage tunnel in the side slope of water retaining structure downstream, forms the groundwater table that multilayer slope drainage curtain reduces two sides side slope, thus improves side slope permanent stability.In this type of Excavation of High And Steep Slopes Bracing Process, often there is side slope thin layer excavation, the construction Difficulties that transport routes are difficult to arrange is slagged tap in construction.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned existing problems, there is provided a kind of for the shaft structure of slagging tap in Excavation of High And Steep Slopes engineering, be intended to the problem solving difficult deslagging in high gradient slope construction, the mode of slagging tap fixed relatively, reduces and other mutual interference of constructing.
The technical scheme that the utility model adopts is: a kind of for the shaft structure of slagging tap in Excavation of High And Steep Slopes engineering, comprise the drainage tunnel that high gradient slope is close with the some layers of lower planes position be arranged in this side slope, it is characterized in that: at the deslagging vertical shaft of a periphery up/down perforation of described each layer drainage tunnel, this silo bottom is provided with hole of slagging tap; Described deslagging vertical shaft is connected hole with arranging between drainage tunnel, and the slagging tray smooth connection of excavate near the employing oblique angle, side of deslagging vertical shaft in hole is propped up in this connection.
Described hole of slagging tap is arranged in the bottom of high gradient slope and is excavated to the axial location of deslagging vertical shaft.
The beneficial effect of this patent is: the utility model utilizes the multilayer drainage tunnel arranged in high gradient slope, adopt raise boring machine to bore one and drainage tunnel is carried out the vertical vertical shaft of slagging tap connected, and to be transported by drainage tunnel by the rock ballast of each slope excavation and down to the hole of slagging tap of silo bottom of slagging tap, thus transport slag field to by hole of slagging tap; Solve the problem of slagging tap in high gradient slope construction, and mode of slagging tap relatively is fixed, can be reduced and other interference of constructing.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the present embodiment comprises the high gradient slope 1 of System drainage curtain, the multilayer drainage tunnel 2 be arranged in high gradient slope, connects the vertical shaft 3 of slagging tap of levels (horizontal direction) drainage tunnel, is arranged on the hole 4 and be arranged on drainage tunnel 2 and hole 5 and slagging tray 6 are propped up in the connection of slagging tap between vertical shaft 3 of slagging tap of silo bottom of slagging tap.
The specific implementation method of the present embodiment is as follows:
The axis of a, vertical shaft 3 of determining to slag tap according to the axial location of each layer drainage tunnel 2 in high gradient slope 1, and hole 4 of slagging tap bottom side slope is excavated to the axial location of vertical shaft 3 of slagging tap, utilize on domatic raise boring machine to carry out slagging tap the Rapid Excavation (as shown in Figure 5) of vertical shaft 3.
B, when after elevation higher than certain layer of drainage tunnel 2 in high gradient slope 1 of the excavation elevation of vertical shaft 3 of slagging tap, connect a hole 5 from drainage tunnel 2 side excavation, and in this hole near employing oblique angle, vertical shaft 3 side excavation of slagging tap as slagging tray 6 (as shown in Figure 3, Figure 4).
C, above-mentioned drainage tunnel 2 is communicated with vertical shaft 3 of slagging tap after, can slope excavation tap cinder construction be carried out.
Claims (2)
1. one kind for the shaft structure of slagging tap in Excavation of High And Steep Slopes engineering, comprise high gradient slope (1) and be arranged on the close drainage tunnel (2) in some layers of lower planes position in this side slope, it is characterized in that: at the deslagging vertical shaft (3) of a periphery up/down perforation of described each layer drainage tunnel (2), this silo bottom is provided with hole of slagging tap (4); Described deslagging vertical shaft (3) is connected hole (5) with arranging between drainage tunnel (2), and slagging tray (6) smooth connection of excavate near the employing oblique angle, side of deslagging vertical shaft (3) in hole is propped up in this connection.
2. according to claim 1 for the shaft structure of slagging tap in Excavation of High And Steep Slopes engineering, it is characterized in that: described in hole (4) of slagging tap be arranged in the bottom of high gradient slope (1) and be excavated to the axial location of deslagging vertical shaft (3).
