Abstract
The invention relates to the field of water conservancy and hydropower, in particular to a structure for monitoring the pass-through condition during diversion tunnel blocking construction. According to the structure for monitoring the pass-through condition during diversion tunnel blocking construction, the construction way is simple, and the pass-through condition during diversion tunnel blocking construction can be monitored effectively in real time. The structure for monitoring the pass-through condition during diversion tunnel blocking construction comprises a reservoir and a diversion tunnel communicated with the reservoir, wherein the diversion tunnel is divided into a front plug tunnel section and a plug section, an osmometer is fixedly arranged in the front plug tunnel section, and the plug section is completely blocked through concrete. According to the structure, construction processes are simple and can be executed easily, an original structure is slightly changed, and the structure can be widely popularized quite easily; meanwhile, the dredging state of the diversion tunnel can be monitored in real time, and the structure is particularly suitable for construction detection of hydroelectric diversion tunnels.
Description
Technical field
The present invention relates to field of water conservancy, especially a kind of Diversion Tunnel plugging construction phase through condition monitoring structure.
Background technology
Hydroelectric project commonly uses the osmotic pressure at position such as engineering such as osmometer monitoring dam body, tunnel etc.For monitoring the shutoff quality of Diversion tunnel plug, generally using osmometer to monitor the osmotic pressure of plug between bulkhead concrete and lining concrete or basement rock, but the through situation of plug front hole section and reservoir cannot be reflected.Traditional practice is indirectly judged by osmometer, seepage discharge, joint meter and dislocation meter etc., and the Monitoring Design as the Diversion tunnel plug of the hydroelectric projects such as Pubugou Project, dark small stream ditch all have employed osmometer.The shortcoming of this determination methods is that the promptness of the through situation judging plug front hole section and reservoir and accuracy are poor.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of form of construction work, and the Diversion Tunnel plugging construction phase that Diversion Tunnel plugging construction phase through situation can be monitored effectively in real time through condition monitoring structure.
The technical solution adopted for the present invention to solve the technical problems is: Diversion Tunnel plugging construction phase through condition monitoring structure, the Diversion Tunnel comprising reservoir and communicate with reservoir, described Diversion Tunnel is divided into plug front hole section and plug section, described plug front hole section internal fixtion is provided with osmometer, and described plug section is by the complete shutoff of concrete.
Further, another osmotic pressure device is provided with in described plug section.
Further, the concrete of described plug section carries out shutoff by backfill grouting or joint grouting.
The invention has the beneficial effects as follows: when reality uses, if the osmometer reading in the section of plug front hole is zero, illustrates in hole and do not have water or water level not to exceed this position; If the osmometer reading in the section of plug front hole and in good time reservoir level contrast have a long way to go, illustrate that connectivity is poor.If osmometer reading and in good time reservoir level contrast differences, apart from less even identical, illustrate that connectivity is good, need to cause the vigilant of construction department, but, if now plug has been constructed, be then safe from harm.According to the through situation of tunnel and reservoir, if necessary, engineering measure can be taked in time, ensure construction quality and the construction safety of Diversion tunnel plug.Working procedure of the present invention is simple, little to the change of original structure, is extremely beneficial to and promotes widely, simultaneously, also real-time monitoring is served to the dredging state of Diversion Tunnel, be particularly useful in the construction detection of water power Diversion Tunnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Be labeled as in figure: reservoir level 1, reservoir 11, Diversion Tunnel 12, plug front hole section 2, osmometer 3, plug section 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
The through condition monitoring structure of Diversion Tunnel plugging construction phase as shown in Figure 1, the Diversion Tunnel 12 comprising reservoir 11 and communicate with reservoir 11, described Diversion Tunnel 12 is divided into plug front hole section 2 and plug section 4, described plug front hole section 2 internal fixtion is provided with osmometer 3, and described plug section 4 is by the complete shutoff of concrete.The present invention is when practical application, and the through situation judgment mode carried out is such: if osmometer 3 reading is zero, illustrates in hole and does not have water or water level not to exceed this position.If the reading of osmometer 3 and in good time reservoir level 1 contrast have a long way to go, illustrate that connectivity is poor.If osmometer 3 reading and in good time reservoir level 1 contrast differences are apart from less even identical, illustrate that connectivity is good, need to cause vigilant, certainly, if now plug section 4 has been constructed, be then safe from harm.General, in order to improve the concrete intensity of back segment plug section 4, preferably carrying out backfill grouting or joint grouting construction, and improving its grouting pressure, thus ensureing the grouting quality of plug.General, also can select to arrange another osmotic pressure device in plug section 4, and judge in conjunction with the integrality of the osmometer 3 pairs of Diversion Tunnels 12 in plug front hole section 2.
When Specific construction, osmometer 3 generally should ponding in Diversion Tunnel 12 and mud drained after, plug section 4 is installed before starting formwork erection.
