وقتي سرسره‌ی بتن به‌كار گرفته مي‌شود، شيب سرسره بايد به حدي باشد كه از جداشدگي جلوگيري شود و نبايد از نسبت 2 عمودي به 3 افقي كمتر باشد. همچنین نباید از 3 عمودی به 2 افقی بيشتر باشد. لوله مي‌تواند صلب و يا انعطاف پذير باشد. حداقل قطر لوله باید در بالای لوله 8 و در پايين 6 برابر حداكثر اندازه‌ی اسمي سنگدانه باشد. محدودیتی در مورد ارتفاع بتن‌ریزی با لوله وجود ندارد. The slope should be constant and steep enough to permit concrete of the required slump to flow continuously down the chute without segregation. The pipe should have a diameter of at least eight times the maximum aggregate size at the top 6 to 8 ft (2 to 3 m) of the chute, but can be tapered to approximately six times the maximum aggregate size below. ✔️@AlirezaeiChannel 🌐www.M-Alirezaei.com

A project of our size needs at least a few hundred million dollars per year to keep going,” Mr. Durov wrote in his public channel on Telegram late last year. “While doing that, we will remain independent and stay true to our values, redefining how a tech company should operate.
The STAR Market, as is implied by the name, is heavily geared toward smaller innovative tech companies, in particular those engaged in strategically important fields, such as biopharmaceuticals, 5G technology, semiconductors, and new energy. The STAR Market currently has 340 listed securities. The STAR Market is seen as important for China’s high-tech and emerging industries, providing a space for smaller companies to raise capital in China. This is especially significant for technology companies that may be viewed with suspicion on overseas stock exchanges.
