Steel sheet piles require soft soil layers with abundant water, and are suitable for clay, silt, sandy soil, silt and other soil layers. Steel sheet piles are less affected by soil during construction, so they can also be used in foundation excavation and soil replacement projects in civil engineering to provide protection for the smooth progress of the project. However, steel sheet piles are not suitable for particularly hard soil layers, such as hard soil layers containing pebbles, gravel, boulder soil layers and rocks. These soil layers are characterized by hard soil and are not easy to be driven in or out. Therefore, when using steel sheet piles, special attention should be paid to avoid using them in these types of soil layers.
Applicable conditions for steel sheet piles:
1. Soil conditions
Steel sheet piles are mainly suitable for places with soft soil and easy collapse, such as soft soil, silt, sand wells, silt, etc. They are also suitable for foundation construction of temporary roads, oil fields, reservoirs, etc. For soil layers with more sediment and high porosity, steel sheet piles can also be installed by pumping water.
2. Groundwater level
When constructing steel sheet piles, it is necessary to pay attention to the height of the groundwater level. It is usually suitable for construction sites where the groundwater level is more than 1.5m deeper than the bottom of the foundation. If the groundwater depth is shallow, the pile body needs to be reinforced or other foundation construction methods need to be adopted.
3. Topographic conditions
Before construction, the topographic conditions of steel sheet piles need to be considered. They cannot be constructed in areas with obvious elevation differences and large soil heterogeneity. They need to be constructed in relatively flat and stable areas.
4. Construction technology
Steel sheet pile construction generally adopts self-dig hole construction method. Before construction, it is necessary to conduct topographic survey and engineering measurement, formulate a reasonable construction plan, ensure good construction quality, and also pay attention to safety protection during construction.
5. Environmental conditions
During steel sheet pile construction, it is necessary to pay attention to the influence of the surrounding environment and avoid construction in polluted and humid environments. At the same time, with the increasing awareness of environmental protection, it is necessary to use environmentally friendly materials to ensure less environmental pollution.
Application areas of steel sheet piles:
(1) Civil engineering: commercial and residential buildings, hospitals, schools, industrial plants and other buildings with basements that require foundation pit support;
(2) Municipal engineering: underground pipelines, integrated pipeline corridors, bridge piers, etc.;
(3) Hydraulic engineering: bridge piers, river regulation (relocation), docks, pump stations, docks and other projects that require cofferdams;
(4) Others: other foundation pit projects that require soil and water retaining and have a certain excavation depth.
The above is an introduction to the applicable conditions of steel sheet piles. It is necessary to choose according to the actual situation and pay attention to construction quality and safety issues. When purchasing steel sheet pile materials, you also need to pay attention to the selection of materials, specifications, etc. to meet engineering requirements.
