【正文】 markets in particular distance near pit, strictly controlling deformation of Foundation pit by the Department for this project, the monitoring of Foundation pit. 3, unearthed in the pit: as the project is located in the city center, excavation of large earthmoving required when shipping, this is subject to reasonable arrangements planned and coordinated work on the outskirts of unearthed. 4, traffic: the project covering 7 traffic organization during construction, the project has been pleted the main structure of a traffic organization and Fengqi road traffic organization work. Transport organizations directly related to the project39。s construction progress.: 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。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。m more interested in is the construction of steel structure of main tower. The perimeter of the main tower made of welded steel plate, after steel plate welded into the rectangle and then pouring concrete. During construction of the main tower, construction unit went out on loan from 31 heavy industry group for hoisting two largetonnage crane machines. Construction of steel structure of main tower is by sections, each segment the weight shown in the table below, we can see the difficulty of construction. Large sections of the Tower weightIn ten Tang Heng bridge watch during our first so directly contact with the bridge in construction State. This allows us to have a deeper feeling. First, as a bridge with the landscape, its design was more brilliant, two tilt Bridge viewed from the distance and rely on each other when the main tower structure, turned out to appear in the scene, we will issue voice of praise. We walked to the nearby looking at more than 80 metres from the main tower, it39。s roads and bridges is a failure, it is frog in the idea! but we don39。s future has a great influence on the development of road and bridge construction, which requires that we now learn professional knowledge, with better expertise at a later time. I can39。s pride of place in road and bridge in the future. It is under the efforts of generations of people in road and bridge, bridge construction in China has been developing by leaps and bounds. Construction of road and bridge engineering in China with large scale, high speed, technical level has been greatly improved, and in some areas they have leading positions in the world. For example the practice seen in Hangzhou Bay CrossSea Bridge and Sutong bridge and other heavyweight works all reflect the strength of bridge engineering. But in spite of this, we would like to see my level of some shortings, such as innovation in bridge design, as in project organization and management, in architecture, for example on the use of new materials, which are in the construction of bridge engineering gap with advanced countries. After this internship, we are national 985 University students as outstanding reserve force of national highway and bridge specialty, our responsibility is great. You can39。 sterilant herbicide, Diuron, and other lawn or lawn weed control of updates. Herbicide use is plicated, effect change over a number of factors, improper use can cause great losses and therefore should be carefully tested before use and preparation, concentration, tools used should be responsible. 5, the pierced holes on the lawn of ventilation holes, aims to improve the ventilation of roots, soil moisture content, to improve the effect of fertilization. The work to improve the quality of turf plays an important role. General requirements for 50 points/m2, 15cmx5cm hole spacing and hole diameter , cave deep 8cm hollow Iron Rod mantie hole available, we can use lawn punching machine (restore root aeration machine) purposes. Root cutting b b the grass on the lawn, remove excess grass, improve the quality of grass growth. Lawn with had larger load or often by load of role, soil harden, can used lawn vertical trim machine, with milling knife dug wide , and spacing for 25cm, and deep about 18cm of ditch, in ditch within fill into more hole material (as sponge soil), put dug of soil turned came, and put remaining soil shipped go, application efficient fertilizer, and fill broadcast grass seed, strengthening fertilizer management, lawn can soon growth plex strong. Six, green cultivation and management of the emergency remedy 1, strengthen of the seedlings increased planting mo
