✅ هفت نکته طلایی برای نظارت و اجرای فونداسیون بتنی :

1. ابعاد و موقعیت دقیق فونداسیون باید طبق نقشه‌ها و با کنترل دوربین نقشه‌برداری پیاده‌سازی شود.

2. زیرسازی و بستر خاک باید کاملاً متراکم، تراز و عاری از مواد آلی یا آب ایستا باشد.

3. قالب‌بندی باید مستحکم، نفوذناپذیر و با ابعاد دقیق انجام شود تا از تغییر شکل بتن جلوگیری شود.

4. میلگردگذاری باید طبق نقشه‌های اجرایی و با رعایت کاور بتنی مناسب (حداقل 5 سانتی‌متر) صورت گیرد.

5. بستن آرماتورها با سیم، نصب اسپیسر و رعایت فواصل آرماتورها الزامی است.

6. بتن‌ریزی باید پیوسته، بدون وقفه طولانی و با ویبره مناسب جهت حذف هوای محبوس انجام شود.

7. عمل‌آوری بتن (کیورینگ) پس از بتن‌ریزی با آب‌دهی یا پوشش مرطوب حداقل به مدت 7 روز ضروری است.

Telegram Auto-Delete Messages in Any Chat

Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
