Problems solved by technology
However, due to the complex geological structure in various regions, the design and construction are difficult, and it is difficult to do it once and for all. Waterproofing and water control have always been one of the major problems in tunnel engineering construction. At present, many tunnels in my country still have the disadvantage of water leakage during operation. To some extent, it affects the safety operation
The cost of rework and maintenance for plugging and leaking water is very high. According to relevant information: per square meter of underground concrete components, the water seepage volume is 10 milliliters. The larger the tunnel section, the more water seepage. Waterproof measures, due to the stretching effect of concrete shrinkage cracks, the waterproof layer will be partially broken and damaged, causing dripping and freezing of railway tunnels, often causing electrical system failures and affecting the normal operation of trains; water leakage in highway tunnels causes water accumulation on the road, Freezing in winter causes frequent car accidents, causing unsafe hazards

Abstract
The invention belongs to a flow guide channel type ductile cast iron tunnel wallboard with high strength and toughness. The flow guide channel type ductile cast iron tunnel wallboard comprises multiple gridding reinforcing ribs (3) uniformly arranged on the inner side of a ductile cast iron wallboard (2) and borders (5) arranged on the periphery, and is characterized in that a flow guide channel (4) is formed in the circumference of the upper end of the border (5) located on the right side; multiple siphon hard-plastic pipes (1) are uniformly mounted between the borders (5) at the two ends, and multiple siphon holes (11) are formed in the siphon hard-plastic pipes (1); the right ends of the siphon hard-plastic pipes (1) are communicated with the flow guide channel (4); a flow guide channel mesh cover (6) is mounted on the flow guide channel (4). The flow guide channel type ductile cast iron tunnel wallboard has water collecting and flow guiding functions, and trains and vehicles operate in a tunnel safely and reliably; the tunnel maintenance cost is low, the service life is long, and the ductile cast iron wallboard is high in tensile strength and the elongation, good in corrosion resistance, simple in structure and convenient and fast to construct.
Description
technical field [0001] The invention belongs to an underground tunnel support and protection component, in particular to a diversion groove type high-strength ductile iron tunnel wall plate used in railways, highways, rivers underwater and subsea tunnels. Background technique [0002] At present, in the construction and construction of underground tunnels in my country, the design and construction of tunnels are mainly based on the basic principles of the New Austrian Method, especially for underground, underwater, urban subway and subsea tunnels, etc., which are designed and constructed by shallow buried excavation. Its core technology is to first use various auxiliary technical measures to strengthen the surrounding rock mass during construction, fully mobilize the self-supporting capacity of the surrounding rock, support it in time after formal excavation, close it into a ring, and perform a lining arch wall as the main bearing structure. After a few days of curing and soli...
