泰州樁基工程特點、要點及施工工藝(素材)

一、設計要求
1、根據工程地質條件、各建構筑物上部荷載的情況及對沉降的要求，本工程將采用PHC管樁及淺層地基處理方法.
2、主廠房基礎、汽機基礎、鍋爐爐架、集控樓、煙囪基礎、煤系統等荷載較大，對沉降的控制標準較高，采用Φ600PHC130（110）樁；主廠房附屬設備基礎、爐后構筑物、電除塵、煙風道支架、風機基礎、A排外構筑物、干煤棚、化水等采用500×110PHC管樁；循環水管溝、材料庫、油泵房、推煤機庫等輔助、附屬建構筑物將采用水泥攪拌樁.
3、PHC管樁采用錘擊沉樁法。入土深度約為50米和39米左右，達到持力層⑧粉細砂層和⑥層。
4、管樁各部位根據設計要求進行送樁，深度約2-7米。
二、工程特點
1、由于本工程地處長江灘塗地質條件
Taizhou foundations characteristics, elements and construction process (material)

First, the design requirements
1, according to geological conditions, the construction of the upper structure and the settlement of the case load requirements, the project will use the PHC pile and shallow foundations approach.
2, Main Building foundation, based turbine, boiler furnace frame, control building, chimney foundation, a larger coal system load, the higher on the settlement of the control standards, using Φ600PHC130 (110) pile; main plant ancillary equipment foundation, furnace after structures, ESP, Flue bracket, fan base, A xenophobic structures, dry coal shed, of water pipe with 500 × 110PHC; circulating water channel, material warehouse, oil pump, push coal hangar and other auxiliary, subsidiary structures built will use cement mixing pile.
3, PHC pile used Driven Piles. Embedded depth of about 50 meters and 39 meters to reach the bearing layer ⑧ ⑥ layer and layer of fine sand.
4, pipe design requirements for each part sent under the pile, the depth of about 2-7 meters.
Second, the engineering characteristics
1, as the project is located in the geological conditions of the Yangtze River beach
