Abstract
The utility model discloses a plugging structure for a diversion tunnel with a shorter choke plug length. The plugging structure for the diversion tunnel comprises a diversion tunnel with a plugging area, wherein a choke plug for plugging the diversion tunnel is poured in the plugging area of the diversion tunnel, and at least one site of the cross sectional areas of the choke plug is greater than the cross sectional areas of the diversion tunnel at two ends of the plugging area. According to the plugging structure, the choke plug can be clamped in the diversion tunnel, so that the stability of the choke plug can be effectively guaranteed, therefore, a diversion culvert can be plugged by the plugging structure only with a very short choke plug, the temperature of the choke plug is easily controlled when the choke plug is poured, the plugging structure is convenient to construct, the construction period can be shortened, and the cost can be further saved. The longitudinal section shape of the diversion tunnel of the plugging area is set to be wedge-shaped, so that the stability of the choke plug can be greatly improved. The plugging structure can be popularized and used in the field of hydraulic and hydro-power engineering.
Description
Technical field
The utility model relates to the Hydraulic and Hydro-Power Engineering field, especially a kind of Diversion Tunnel plugging structure.
Background technology
The water conservancy diversion outlet structure escape works are meant in the work progress of Hydraulic and Hydro-Power Engineering the lead provisional outlet structure escape works in downstream of river.Water conservancy diversion outlet structure escape works commonly used have diversion canal, diversion tunnel, water conservancy diversion bottom outlet, diversion culvert etc., also can adopt aqueduct or utilize the factory building draft tube as the water conservancy diversion outlet structure escape works.The water conservancy diversion outlet structure escape works are after accomplishing water conservancy diversion sluicing task; Usually need be with the shutoff of water conservancy diversion outlet structure escape works; The shutoff of general Diversion Tunnel adopts the mode of concreting plug to carry out shutoff usually; Said Diversion Tunnel can be diversion tunnel or diversion culvert, and the concrete plug of promptly in Diversion Tunnel, building certain-length forms described plug with the Diversion Tunnel shutoff.At present, employed Diversion Tunnel plugging structure comprises the Diversion Tunnel that is provided with the shutoff zone, builds the plug that is useful on the shutoff Diversion Tunnel in the shutoff zone of Diversion Tunnel; The cross-sectional area of said plug is identical with the Diversion Tunnel cross-sectional area at two ends, shutoff zone, because plug and the contact surface of Diversion Tunnel and the axis parallel of Diversion Tunnel, plug is receiving after the external force effect of Diversion Tunnel axial direction; Plug structure stress condition is relatively poor, and plug stability is bad, the way of taking usually be with plug do very long; Though it is stable that this mode can guarantee plug; But in the practice of construction process, if plug length is longer, the plug temperature control requirement is higher in building the process of plug; And the long construction that also is unfavorable for plug of plug, cause the construction period longer.
The utility model content
The utility model technical problem to be solved provides the short Diversion Tunnel plugging structure of a kind of plug length.
The utility model solves the technical scheme that its technical problem adopted: this Diversion Tunnel plugging structure; Comprise the Diversion Tunnel that is provided with the shutoff zone; Build the plug that is useful on the shutoff Diversion Tunnel in the shutoff zone of Diversion Tunnel, the cross-sectional area of said plug has the Diversion Tunnel cross-sectional area of a place greater than two ends, shutoff zone at least.
Further be that the vertical sectional shape of the Diversion Tunnel in said shutoff zone is a wedge shape.
The beneficial effect of the utility model is: because the cross-sectional area of plug has the Diversion Tunnel cross-sectional area of a place greater than two ends, shutoff zone at least, can plug be stuck in the Diversion Tunnel, thereby effectively guarantee the stable of plug; Thereby this plugging structure only needs very short plug can realize the shutoff of diversion culvert; In building the process of plug, control the temperature of plug easily, and easy construction, can shorten the construction period; In addition, can also practice thrift cost.The vertical sectional shape of the Diversion Tunnel in shutoff zone is set to wedge shape, can improve the stability of plug greatly.
Description of drawings
Fig. 1 is the sketch map of the utility model Diversion Tunnel plugging structure;
Description of symbols among the figure: Diversion Tunnel 1, shutoff zone 2, plug 3.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1; This Diversion Tunnel plugging structure; Comprise the Diversion Tunnel 1 that is provided with shutoff zone 2, build the plug 3 that is useful on shutoff Diversion Tunnel 1 in the shutoff zone 2 of Diversion Tunnel 1, the cross-sectional area of said plug 3 has Diversion Tunnel 1 cross-sectional area of a place greater than 2 two ends, shutoff zone at least.Because the cross-sectional area of plug 3 has Diversion Tunnel 1 cross-sectional area of a place greater than 2 two ends, shutoff zone at least, can plug 3 be stuck in the Diversion Tunnel 1, thereby guarantee that plug 3 is stable; Thereby this plugging structure only needs very short plug 3 can realize the shutoff of Diversion Tunnel 1; In the process of building plug 3, control the temperature of plug 3 easily, and easy construction, can shorten the construction period; In addition, can also practice thrift cost.The vertical sectional shape of the Diversion Tunnel 1 in said shutoff zone 2 can have any shape; As long as plug 3 cross-sectional areas have Diversion Tunnel 1 cross-sectional area of a place greater than 2 two ends, shutoff zone at least; As preferred mode be: the vertical sectional shape of the Diversion Tunnel 1 in said shutoff zone 2 is a wedge shape; Can guarantee effectively that plug 3 is stable; Cross section after the longitudinal section of said Diversion Tunnel 1 is meant and with any tangent plane of crossing Diversion Tunnel 1 axial line Diversion Tunnel 1 is cut, the cross section of said Diversion Tunnel 1 are meant with the cross section after perpendicular to the tangent plane of Diversion Tunnel 1 axial line Diversion Tunnel 1 being cut arbitrarily.
The work progress of this Diversion Tunnel plugging structure is following: at first, confirm shutoff zone 2 according to the relation of plug and water conservancy project curtain; Secondly, confirm the length of plug 3, when confirming the length of plug 3, need take into full account the performance of the disconnected cohesive force of shearing resistance at Diversion Tunnel 1 position that contacts with plug 3; Then Diversion Tunnel 1 expansion in shutoff zone 2 is dug, making diversion culvert 1 vertical sectional shape in shutoff zone 2 is wedge shape, expands the degree of depth of digging and decides according to the cross section size of Diversion Tunnel 1; In shutoff zone 2, form plug 3 with concreting at last, thereby form whole Diversion Tunnel plugging structure, said Diversion Tunnel 1 can be diversion culvert, diversion tunnel etc.
Claims (2)
1. Diversion Tunnel plugging structure; Comprise the Diversion Tunnel (1) that is provided with shutoff zone (2); Build the plug (3) that is useful on shutoff Diversion Tunnel (1) in the shutoff zone (2) of Diversion Tunnel (1), it is characterized in that: the cross-sectional area of said plug (3) has Diversion Tunnel (1) cross-sectional area of a place greater than (2) two ends, shutoff zone at least.
2. Diversion Tunnel plugging structure as claimed in claim 1 is characterized in that: the vertical sectional shape of the Diversion Tunnel (1) in said shutoff zone (2) is a wedge shape.
