河北工業(yè)大學教學實驗主樓
基礎降水工程施工方案

施工單位：河北建設集團

一、 編制依據(jù)（略）
二、 工程概況：
河北工業(yè)大學教學實驗樓位于天津市虹橋區(qū)光榮道8號，河北工業(yè)黨東院
院內(nèi)，是一座寓教學、科研、實驗于一體的綜合性教學樓。主樓為13層鋼筋砼框剪結構，局部14層，地面以下地室一層為整體式鋼筋砼箱形結構，深5.4m。地下室底板平面尺寸89.6×22.1m，設計采用鉆孔灌注樁基礎，在基坑開挖前已施工完畢，現(xiàn)場自然地坪標高－1.2米左右，要求基坑范圍內(nèi)降水至基底以1米，即降至標高－6.4m，地面以下處5.2m。
由天津市勘察院勘察第1999－2－008號地質(zhì)報告得到淺層土土質(zhì)狀況如
下：
　　1．人工填土層：厚度1.5～2.20m由上部雜填土和下部素填組成，層底標高3.55～2.61m。
　　2．新近沖擊層：厚度為4.60～2.20m，頂部標高3.55～2.61m，由上部粉質(zhì)粘土及下部
Hebei University of Technology Teaching Experiment Main
Construction scheme based on precipitation

Construction Unit: Hebei Construction Group

First, the preparation according to (slightly)
Second, project overview:
Hebei University of Technology Laboratory Building is located in Hongqiao District, Tianjin, glorious, 8, Eastern Hospital of Hebei Party
Hospital, is one to put teaching, research, experiment in integrated teaching building. Main building is 13 story reinforced concrete frame structure, the local 14-story, ground floor room as a whole the following way reinforced concrete box structure, depth 5.4m. Basement flat size of 89.6 × 22.1m, with bored pile foundation design, in the excavation before construction is completed, the scene of natural floor elevation -1.2 m, required excavation to the basement to within 1 meter of precipitation that down to elevation-6.4m, below the surface Department 5.2m.
Investigation by the Tianjin Institute of Geological Survey Report No. No. 1999-2-008 soil conditions, such as by shallow soil
Next:
1. Artificial fill: thickness 1.5 ~ 2.20m from the upper and lower fill factor fill mixed composition, bottom elevation 3.55 ~ 2.61m.
2. Recent shock layer: thickness 4.60 ~ 2.20m, the top elevation of 3.55 ~ 2.61m, silty clay from the top and bottom
