The difference between a hidden ditch and an open ditch lay in their meaning, function, and the vertical slope at the bottom of the ditch. A hidden ditch was a ditch that guided water below the ground. It was mainly used for underground drainage and did not have the function of seeping or collecting water. The open ditch referred to the drainage ditch without a ditch cover outside the outer wall of the house. Its function was to quickly and systematically guide the surface water and rainwater into the sewer to prevent the foundation of the house from being soaked in water and permeating, so as to ensure the stability and durability of the house. In addition, the vertical slope at the bottom of the hidden ditch should be greater than 0.5%, while the slope at the bottom of the open ditch should be about 0.3~0.5%.

Open ditch drainage and underground ditch drainage were two different drainage methods. Open ditch drainage referred to the digging of open ditches on the surface to guide water to the water outlet. It was suitable for draining accumulated water after heavy rain or for green areas with uneven terrain. Open ditches had the advantage of easy drainage, easy flushing, and anti-blockage, but there might be problems with odors and pests, and it would also make the ground uneven. Underground ditch drainage was used to draw water out by burying pipes or building underground ditches. It was suitable for narrow sites and large underground water. Underground ditches could keep the terrain neat and save land, but the cost was higher. There were differences in drainage methods, cover materials, and functions between open ditches and underground ditches.

Open ditches and drainage ditches were used for drainage, and there were some differences between them. The open ditch was an open drainage facility, usually made of concrete or stone, used to collect and discharge rainwater and sewage. Open ditches were usually located on both sides of the road or around the buildings. They could effectively discharge rainwater and sewage to prevent water from soaking the buildings or roads. The advantage of open ditches was that they were easy to clean and maintain, but the disadvantage was that they were easily blocked by garbage and debris. The drainage ditch was a facility used to discharge rainwater and sewage. It was usually built with concrete or plastic pipes to collect and discharge rainwater and sewage. The advantage of the drainage ditch was that it had a large drainage capacity and high drainage efficiency, but the disadvantage was that it was easy to block and pollute, and it needed to be cleaned and maintained frequently. Generally speaking, open ditches and drainage ditches were both used for drainage, but open ditches were open while drainage ditches were closed.

Open ditch drainage and underground ditch drainage were two different drainage methods. Open ditch drainage referred to the drainage of water through the excavated open ditch channel. Water could flow directly from various positions in the ditch. The cover was usually a comb, which could pass water. The comb or grill was used to intercept debris. Underground ditch drainage meant that water could not flow in directly. The cover was usually steel plate or concrete. The drainage ditch of the underground ditch was inclined to the water collecting well. When digging, the drainage ditch was first dug, and as it was dug, it deepened to form a underground ditch system connecting the inside and outside of the foundation pit to control the underground water level. Finally, the underground water was pumped away by a pump. Open ditch drainage was suitable for irrigation in areas with water infiltration, and it had a good effect on rainwater drainage. Dark ditch drainage was suitable for the foundation pit drainage of structures with large foundation pit depth, narrow site, and strong underground water.

In the twenty-fifth episode of the celebration, the chain locked a box. The contents of the box were a Barrett sniper rifle and two letters. The first letter was written to Wu Zhu, expressing his longing for Wu Zhu and hoping that he would destroy the box after reading the letter to prevent it from falling into the hands of someone with ill intentions. The second letter was for the descendant Fan Xian. It mentioned Fan Xian's background and Ye Qingmei's origins.

Open ditch drainage was a commonly used method of drainage. It was suitable for the removal of a small amount of underground water, surface water, and rainwater in the foundation pit. Open ditch drainage is composed of open drainage ditch, water collecting well, water intake, horizontal support, vertical support plate, etc. The conditions for the use of open ditch drainage include geological conditions and aquatic conditions. The geological conditions were suitable for denser soil layers, especially soil layers with a certain degree of cohesion or stickiness, as well as hard clay mixed with sand lenses or thin layers without water supply. The water condition is suitable for the situation where the flow of underground water is small. The construction plan of open ditch drainage included the arrangement of the drainage line, the number and location of the water collecting wells, the excavation of the open ditch and the setting of the water collecting wells. The open ditch drainage method had the advantages of low cost, simple construction, and obvious effect. It was widely used in fields such as farmland, urban roads, and gardens.

Open ditch drainage was a method of lowering water. By setting up open drainage ditches or infiltration channels and collecting wells in the foundation pit, water was pumped out of the foundation pit. The open ditch drainage system was composed of a water collecting well, a water intake, a horizontal brace, a vertical brace, and a drainage ditch. It is suitable for drainage projects where the foundation pit is shallow, the depth of drainage is not large, and there is no quicksand and piping at the bottom of the pit. Open ditch drainage was a commonly used and simple method of rainfall. It was suitable for the drainage of a small amount of underground water, surface water, and rainwater in the trench.

The iron lock was a type of mountaineering equipment that was commonly used for activities such as forming groups, protecting, crossing rivers, climbing, rescuing, and transporting the wounded. There were many models, including D, Alan, O, and hybrid. The iron lock was mostly made of steel or aluminum alloy, and its resistance to tension reached 1800 kg. In addition to being used in mountaineering, iron locks could also be used to connect equipment, such as ascenders and wheels. In addition, Tiesuo was also the pen name of an outstanding novelist. He had created many wonderful novels.
