　　Shanxi Lucheng Production Observation Standard Settlement Observation Point Specification Complete

　　Settlement observation points should be comprehensively considered based on factors such as the shape, structure, geological conditions, and pile shape of the building, and should be placed in locations that can sensitively reflect changes in building settlement. It is generally installed at the corners of buildings, in locations with significant differential settlement, in sections with significantly different geological conditions, and on both sides of settlement cracks. When burying, pay attention to the reliable connection between the observation point and the building, so that the changes in the observation point can truly reflect the changes in the building. And based on the floor plan design drawings of the building, draw a settlement observation point layout diagram to determine the location of the settlement observation points. A fixed observation route should be established between the working point and the settlement observation point, and marker posts should be made at the instrument installation station and transfer point to ensure that each observation follows a unified route.

　　The cycle and measurement process of settlement observation

　　The period of settlement observation should reflect the settlement deformation law of buildings. Settlement observation of buildings (structures) has strict time constraints, especially observation must be carried out on time, otherwise the original data of settlement observation cannot be obtained, resulting in incomplete observation results. The retesting of other stages must be carried out regularly according to the progress of the project, without missing or supplementing the measurement, only in this way can accurate settlement conditions or patterns be obtained. It is generally believed that buildings built on sandy soil layers have mostly completed their settlement during construction, while buildings built on clay soil layers have only a partial settlement during construction, and therefore, the settlement period is variable. Based on work experience, during the construction phase, the frequency of observation should be higher. Generally, the observation period is determined by 3 days, 7 days, or 15 days, or by increasing the number of layers and loads. The specific observation period should depend on the foundation and loading during the construction process. When temporarily suspending work, observation should be conducted once during the suspension and once again during the resumption of work to check the changes in building settlement during the suspension period. This serves as a basis for determining whether the method and frequency of settlement observation should be adjusted after resuming work. After completion, the frequency of observation can be reduced, depending on the type of foundation soil and the magnitude of settlement rate. Generally, there are different periods such as one month, two months, three months, six months, and one year. Whether the settlement has entered a stable stage should be determined by the relationship curve between settlement amount and time. For key observation and scientific research projects, if the settlement in each of the last three observation cycles is not more than twice the measurement error, it can be considered as entering the stable stage. For settlement observation in general engineering, if the settlement rate is less than 0.01-0.04mm/d, it can be considered as entering the stable stage, and the specific value should be determined according to the compressibility of the foundation soil in each region.

　　Returning from the Spring Festival holiday, the steel market is facing a weak supply-demand situation: there is a risk of tightening production restrictions in North China steel mills in February, and the resumption of work in electric furnace factories will be limited by the squeeze of high priced scrap steel on profits. Although the resumption of production by southern steel mills is expected to offset the reduction, overall output is still expected to slightly decline.

　　February is the usual off-season for demand, and at the same time, there is some suppression of demand in the north during this year's Spring Festival. But with the improvement of the funding situation, the speed of converting existing projects into completion will also accelerate, accelerating construction or forming effective peak season demand in March.

　　Basic Overview of Snails

　　After the futures contract 2205 opened around 45 points high during the day, the morning bearish candlestick fell back due to increased volume. Although there was a surge of 4879 in the afternoon, due to insufficient momentum, the double volume shadow line returned to the negative and fluctuated around the lower edge of the pressure range at 4842. The daily chart formed a false bearish candlestick and closed at 4847, with a 1.74% increase of 48794801.

　　The pressure range of the Thread 2205 contract is 4842-5096, and the support level is temporarily at the one hour cycle MA13 line. The indicator has slightly risen, but the volume is insufficient to follow up. The strong KDJ area is overbought and blunted, and the price may continue to fluctuate to some extent. In the short term, after MA13 breaks the high point of the one hour cycle indicator, it further forms the ability to support the price. The price has not fallen below the high point of MA13, and the bullish trend of retracement is maintained. Pay attention to the pressure near the top 5096 of the pressure range.

　　During the Spring Festival holiday, most markets are closed, and the overall upstream and downstream of steel are basically in a closed state, with light trading; A few steel mills have raised prices by 50-100; Over the past five and a half days, the external market has shown a general upward trend, with crude oil reaching an 88 month high and pushing towards $100. This has boosted the formation of fossil fuels. On January 29th, Singapore's iron ore market fell by more than 2% first, and later rose by 7% during the Chinese New Year period, but still has a gap of 1% compared to the high spread on January 29th.

　　Today, the price of snail 2205 has risen significantly, with a general increase in finished products nationwide and some increasing by over 100%. Reasonable and sufficient liquidity after the Spring Festival; The Ministry of Industry and Information Technology and three other departments have issued guidance to promote the high-quality development of the steel industry, strictly prohibiting the addition of steel production capacity and implementing capacity replacement. In addition, the current strong expectations for infrastructure investment have boosted market sentiment. Merchants are gradually returning, and the market sentiment is relatively optimistic, but there are few substantive shipment operations at the moment. Downstream terminals have not started working normally, demand needs to recover, and transactions are average; In the short term, there is an expectation of an increase or decrease in coke production. Therefore, it is recommended that merchants still need to pay attention to risk prevention and control.
