The biggest immediate challenge for the EU will be replenishing its depleted gas inventories. While the EU could still increase LNG imports from countries such as the US, such purchases would be more expensive.
Refilling natural gas storage space to historical average levels this year could cost 70 billion euros, a sevenfold increase, compared to 10 billion euros in previous years. "
A complete replacement for Russian gas is not only very expensive, but it also may not be possible.
In the next 12 months, there is little way to meet the demand for a "normal" year in the absence of Gazprom, which also includes Foam Lightweight.
The filling elevation of the foam light soil with different strengths shall be constructed in strict accordance with the design requirements. The anti-seepage geomembrane on the top of the foam light soil subgrade shall be laid under the metal mesh, and the lap joint shall be thermally welded, and the lap width shall not be less than 10cm.
When laying, it should be flattened and tightened to avoid local rolling up. If necessary, U-shaped nails can be used for anchoring. When laying the metal mesh, U-shaped nails should be used for anchoring, the longitudinal anchorage spacing is 2m, and the transverse anchorage spacing is 1.0m. The plane position of the metal mesh should be overlapped and overlapped, the width of the overlap should not be less than 5cm, and the overlap should be bound with plastic buckles and anchored with U-shaped nails.
Before the light soil is poured, according to the boundary conditions of the construction site, the pouring area and the pouring layer are first divided, and the base is checked to ensure that the base is free of debris and water, and that the base elevation meets the design requirements and should meet the following requirements:
1) The top surface area of a single pouring area should not exceed 400m2.
2) The length in the long axis direction of a single pouring area should not exceed 20m.
3) 1.8cm thick wooden plywood is used to support the spacing and joints in the adjacent pouring area. The wooden plywood is a temporary support template and is also used as a deformation joint filling and must not be removed.
4) The thickness of the single-layer pouring layer should be controlled within the range of 0.3-1.0m.
5) The thickness of 0.8m at the top of the light soil subgrade must be used as an independent single-layer pouring layer, and the layer should be poured at one time in each pouring area.
Construction Control Points
1) For the adjacent pouring layers in the same section, when the temperature during the construction period is not lower than 15℃, the shortest pouring interval can be controlled by 8 hours; otherwise, the pouring interval should not be less than 12 hours.
2) The pouring construction time of the pouring layer in a single pouring area of foam light soil should be controlled within 2 hours.
3) It should be poured from one end to the other end along the long axis of the pouring area; if more than one pouring pipe is used for pouring, it can be poured side by side from one end, or the diagonal pouring method can be used.
4) During the pouring process, when the pouring pipe needs to be moved, it should be moved back and forth along the direction in which the pouring pipe is placed, and it is not appropriate to move the pouring pipe left and right; Move to the soil surface.
5) During the pouring process, the discharge port of the pouring pipe should be placed below the current pouring surface as much as possible; in other cases such as the surface being smoothed, the distance between the discharge port of the pouring pipe and the current pouring surface should not be higher than 1.5m.
Care and Maintenance
After the top surface of the light soil pouring area is poured to the design elevation, the surface should be covered with plastic film to moisturise and maintain the light soil roadbed; or non-woven geotextile covering and watering should be used for maintenance. The curing time is not less than 7 days.
Before the top of the light soil subgrade is filled with soil, it is strictly forbidden to drive construction machinery on it; if it is unavoidable in some areas, a temporary protective layer with a thickness of not less than 50cm should be laid at a suitable position or covered with steel plates as a temporary access road for Construction machinery travels.
Connection with other processes
The top improved soil must be constructed when the maintenance strength of the light soil under the same conditions reaches 1.5MPa. During construction, it is strictly forbidden for large machinery such as dump trucks, road rollers, and bulldozers to directly walk on the top surface of the light soil. Paving and rolling are carried out in the forward way of leveling and rolling, that is, unloading trucks and road rollers should unload and walk at the rear end of the leveling machine.
During the rainy season, special measures should be taken to prevent and drain the water and soil, especially to prevent water and soil loss. Measures such as film covering and setting of temporary drainage ditches should be adopted to avoid slope erosion and prevent a large amount of water and soil from flowing to the lower light soil pouring surface for pollution. Light soil.

Recently, the Turkish government announced that the Turkish President has signed a presidential decree to provide incentives for its Black Sea gas field development projects, including tax exemptions and other preferential measures.
With a fixed investment of 145.1 billion Turkish lira ($10 billion), the project will employ 1,018 people and produce 14 billion standard cubic meters of gas per year, the decree reads. The incentives involved include tariff and VAT exemptions, as well as a range of tax cuts.
In June 2021, Turkish drill ships discovered 135 billion cubic meters of natural gas in the Sakaria field in the Black Sea, bringing Turkey's total gas discoveries in the region to 540 billion cubic meters.
Turkey imports almost all of its annual gas consumption of about 50 billion cubic meters.
Except for natural gas, the supply and prices of many other Foam Lightweight will continue to be influenced by international situations.
