【正文】 s second task is to watch the new intersection of Tang Lu Jingfang road connection of underground space engineering. Underground space connection project of xintang Lu Jingfang road intersection in new pond road intersects with Fengqi road junction road, Fengqi road along the new road direction setting. Construction of engineering structures using opencut method. Works for the underground twolayer doubleor twostory threeBay rectangular frame structure, retaining structure with diaphragm wall, wall thickness 800mm. Support standard first line of concrete support + 4 steel support, first concrete support the shield section + 4 steel support (the 5th double steel backing for support). Main standard pit depth 16m depth of end well in Foundation pit of . Subsidiary structure in total 9 entrance and 3 Wind Pavilion. According to this there is a project of urban underground space engineering features and difficulties. I are as follows: 1 the pipeline: the works surrounding the main gas, electricity, light current, water supply and other important pipelines, pipeline Manager Basic and parallel to the pit, part of a pipeline crossing the pit needs to be protected. 2, pit monitoring: this works on both sides of the Community traffic, and many surrounding buildings, five farmers 39。s tall and stands in contrast to our small and. I was for the first time this kind of bridgebuilding technology, both design and the construction of tracks! : the first task of the day is to go to Hangzhou subway tunnel excavation site. We walked about a kilometer from the tunnel into the distance to the under construction section. Because only a temporary erection of the access tunnel is a narrow way, so we are basically does not go without interruption all the way. We never made much. Today39。t say this bridge we are failing, that our nation39。s resistance. Autumn fertilization must be stopped as soon as possible, so as to avoid long, shoot too late lignification, antifreeze. 2, protected crowns and roots. Filling pile of dirt at the root Crown after cold winter water is very effective, usually 2030 cm tall pile of dirt and solid. 3, package. Before the winter with straw or rope ... The following points: ① to select agents, prevent plants from harm. II in the valid range should use low concentrations of pesticides. Should pay attention to using different medicaments to prevent pest resistance. ③ may use high pollution, high residues of drugs and interfere with each other, improve control. ④ plant protection practice must be performed to ensure that human and animal safety. Seven, plant maintenance and management standards (a), pruning standards: 1, hedge trimmer, plastic plants: plants with plastic requirements should be carried out in a shoot out 15cm trim, hedgerow should ensure the smooth, clear, distinct. After the summer, we finally look forward to short term bridge engineering practice. This practice is an essential part of the learning process. While, we will in internship of process in the on reality in the of bridge has more directly of contact and study, such on we of courses of learning certainly is favourable of, on the, through this internship everyone on yihou of work environment, and work content also has has deeper of understand, this on is careers employment of we for, undoubtedly will produced is big effect, we then of select will more of rational carefully. After the internship is over, I am very satisfied. This internship I learned as a people39。 fulltime mechanical maintenance group (responsible for watering, cooling, spray during the day), lawn maintenance groups and plant groups. Section with garden plant professional engineer 1, each equipped with the professional technician 1, 2 technicians, carry out their duties. By the Resident Engineer of the conservation section chiefs and marketing grasp work and coordination. After five, lawn maintenance and management of plant construction, often with a 12 lawn maintenance can grow into the fullness of the week. After the lawn grow, but also to carry out regular maintenance and management, to ensure the lawn landscape continues for a long time. Lawn maintenance management including: irrigation, fertilization, pruning, weeding and other links. 1, irrigate irrigation lawn fertility environments can be improved, adding water plant the lawn, is a guarantee of normal lawn. In view of the lawn during the growth season, lawn and the environment is in a State of flux, coordination of water and soil and improving the microclimate of the Center, water cannot be implemented according to a fixed pattern, following a number of technical points for reference. (1) the irrigation time growing season, according to the different periods of precipitation is extremely important and timely irrigation of different grass species. Can generally be divided into three periods: ① turned green before the rainy season. High temperatures during this period, transpiration, water requirements, and is one of the most crucial irrigation under soil water retention properties of strength and rainy periods during which Bush 24. ② largely ceased during the rainy season irrigation. Air humidity during this period, grass transpiration decreased soil moisture content has increased to a level sufficient to meet the needs of lawn growth. ③ to yellowing of the leaf after this period before the rainy season precipitation, evaporation is greater, while the lawn is still in a great stage of life activities, pared with the previous two periods, lawn water requirements increase at this stage, if not timely irrigation, not only affect the growth of grass, also causes yellow. At this stage, according to 45 of irrigation. In short, grass types, water requirements are different, you mustAccording to the climate conditions and plant species to determine irrigation of the lawn. About a day, when irrigation is better depends on irrigation. In theory, the same period as long as the amount o
