Background
Along with the high-speed development of economy and the continuous improvement of the technical level of engineering construction, diversion tunnel construction projects in ecologically sensitive areas with complex conditions are more and more. The ecological sensitive area engineering construction has high requirements on environmental protection, the diversion project Kunming 7-mark kunming tunnel in the Yunnan has an average distance of only about 6km from the Yunnan pond, and the protection and recovery standards on the surrounding environment during the project construction are high. The influence of the tunnel engineering construction on the environment is shown as the influence of the construction on surface groundwater, the influence of waste slag on the environment, the influence of construction wastewater and domestic sewage on the environment and the like. At present, domestic and foreign researches are mostly based on the aspects of underground water environment negative effect evaluation systems and mutual influence mechanisms of tunnels and underground water environments. The research on predicting the characteristics of underground water and protecting the underground water environment in construction is still insufficient, and the research on the protection and recovery of underground water resources in sensitive areas is still weak. The influence of the abandoned tunnel slag on the environment and the comprehensive utilization technology research of the abandoned tunnel slag are not systematic, and the method is particularly suitable for the detection method of the abandoned slag quality, the reduction treatment measures and the like. Therefore, the research on the construction environment protection and restoration technology of diversion tunnels in ecological sensitive areas needs to be carried out by relying on diversion projects in the Yunnan, and the research on the influence and restoration technology of tunnel construction on the peripheral environment, the influence and protection measure of tunnel construction on underground water, the influence and protection measure of tunnel waste slag on the environment, and the treatment and utilization technology of production and living wastewater of tunnel construction are mainly researched. The research is significant. In the tunnel construction process, due to the reasons of geological loosening and the like, the inclined shaft branch hole needs to be grouted, and a grouting valve can be used in a grouting passage.
However, in actual production practice, the following problems exist:
1. the valve in the prior art is generally fixed in position, however, the position of the valve for construction is changed frequently, and the problem of fixing the valve which is changed frequently is still solved.
2. In the prior art, the universal demand of variable flow grouting exists. The solution is often to adjust the flow through the size of rotary valve adjustment aperture, and nevertheless the rotary adjustment aperture is not a linear regulation mode, and very high to the control accuracy requirement, therefore prior art has following solution:
1) the two channels in the rotary valve form a cross channel, one channel hole is large, the other channel hole is small, so that two different flows are realized, however, the grouting is viscous substance, when one channel is through-flow, the other channel is over against the inner wall of the valve cavity, and the viscous substance is in contact with the inner wall of the valve cavity for a long time, so that the impurities on the inner wall are remained.
2) The flow rate is adjusted by using the combined valve core, however, the adjustment usually needs two driving modes, which greatly increases the cost and the volume.
3. In the prior art, the rotary driving structure is usually provided with a protrusion on the driving part, and the driven part provided with a groove matched with the protrusion bears the risk of reduction of structural strength.
4. The valve of prior art often has sampling sensing module, however to the construction valve, because the removal of needs nature is often dismantled, sampling sensing module need be dismantled alone transportation, reinstallation, has consumed a large amount of manpower and materials.
5. In order to realize multifunctional regulation, such as multi-section flow regulation, the prior art can adopt a series valve, and the series valve is actually two valves, so that the cost and the occupied space are large.
6. The prior art flashboard structure is often arranged above, the flashboard is not suitable for being arranged below because the stroke of the flashboard is long, and the adjusting and supporting structure is difficult to arrange and is often complex in structure.
