Price for one set of Guangxi Hechi settlement board roadbed settlement board

Description :

　　The use and observation methods of settlement plates and roadbed settlement plates

　　1. Burial of settlement plate

　　The settlement plate is composed of steel plates, measuring rods, and protective sleeves. The size of the base plate can be customized according to customer requirements. The measuring rod and the base plate are fixed in a vertical position, and the protective sleeve is made of steel pipe sleeve. The sleeve size is suitable to cover the measuring rod and allow the ruler to enter the measuring head. As the filling height increases, the measuring rod and sleeve are also correspondingly raised, with each section not exceeding 55cm in length. After raising, the top surface of the measuring rod should be slightly higher than the upper opening of the sleeve. When not measuring, seal the upper opening of the casing with a cap to prevent the filler from falling into the pipe and affecting the free sinking of the measuring rod.

　　Before installation, the roadbed surface must be compacted, and the installation position must be measured. Once the position is fixed, the bottom elevation of the slab should be measured immediately, and this value should be recorded as the initial value.

　　After filling the height beyond 20cm of the observation rod mouth, compact the entire section, and then extend the measuring rod and protective sleeve of the settlement plate. The extension method can be threaded connection or welding connection (measuring rod welding, protective sleeve connection with adhesive tape). After connection, immediately measure the elevation and calculate the actual connection length.

　　(1) Dig a soil pit of about 500 × 500 × 500mm at the burial site, and level and compact the pit with 30-50mm thick yellow sand.

　　(2) Place the settlement plate flat in the pit, fill the surrounding area with yellow sand and calibrate the level with a level, and then backfill the soil to level and compact it.

　　(3) When filling, the filling should be compacted around the settlement plate first to protect the settlement. The protective sleeve should be buried 30cm away from the bottom plate.

　　(4) After the previous layer of filling material is compacted, excavate the filling material to the protective sleeve at the pre embedded position, open the pipe plug to measure the elevation of the pipe head, and the difference between the two elevations is the settlement between observations. Then connect the previous section of connecting pipe and protective sleeve, measure the elevation of the pipe head, install the pipe plug, backfill and compact, and so on. The height of the pipe head with a good pipe plug should be 3-5cm lower than the formed filling surface.

　　The total PMI index for the steel circulation industry in January 2022, released by the Lange Steel Cloud Platform, was 47.6%, up 0.7 percentage points from the previous month. From the perspective of classification indices, the 10 sub indices that make up the PMI for the steel circulation industry have risen and fallen, with sales volume, delivery speed, inventory level, trend judgment, and purchase intention rising, while sales price, total order volume, procurement cost, environment, and enterprise employees falling.

　　The sales volume index of steel circulation enterprises in January was 45.2%, an increase of 0.9 percentage points from the previous month, and rebounded within the contraction range; The order index is 43.7%, a decrease of 0.8 percentage points from last month, and has fallen slightly within the contraction range. Affected by the traditional off-season demand and some regions, the domestic steel market procurement demand is gradually weakening.

　　The inventory index of steel circulation enterprises in January was 50.3%, an increase of 5.9 percentage points from the previous month. From a regional perspective, all six major regions have rebounded, with the central southern and northwestern regions rebounding, with inventory indices increasing by 11.4 and 10.9 percentage points respectively compared to the previous month. The Northeast, North China, Southwest, and East China regions are the next, with inventory indices rebounding by 6.9, 4.6, 4.5, and 4.1 percentage points respectively compared to the previous month. In terms of scale, the inventory of sample steel circulation enterprises with annual sales exceeding 1 million tons, 500000 to 1 million tons, 100000 to 500000 tons, and below 100000 tons has also rebounded. This indicates that the domestic steel market has officially entered the traditional off-season of demand, and the domestic steel market has also entered the stage of accumulating inventory.
