Construction Scheme for Foundation Pit Drawdown of VATTANAC

Park

一、降水设计方案

I. Drawdown design scheme

1.1、设计参数

1.1. Design data

本工程降水井采用直径300mm波纹管滤管，管井共20根井深22米，井口外露500mm。

300mm corrugated filter pipe is adopted as the drawdown well and there are total 20 wells of 22m deep each. The wellhead exposes by 500mm.

1.2、降水井平面布置

1.2. Layout of drawdown well

降水井布置详见降水管井平面布置图。

The arrangement of drawdown well is shown on the layout of drawdown well.

二、施工准备

II. Construction preparation

2.1、测量放线

2.1. Surveying and setting out

测量放线依据现场测量控制点，标高采用水准仪，并根据井点布置图采用全站仪放线定位。放线经复核后报管理公司确认方可进行施工。

The surveying and setting out shall be based on the field survey control points and optical level shall be used for measuring the elevation. In addition, the total station instrument shall be used for the setting out and positioning according to the layout of well points. Setting out shall be performed after re-recheck and being reported to the management company for confirmation.

2.2、施工用电、用水配置

2.2 Electricity and water for construction

1、施工用电直接从配电房接入，50kVA能完全满足降水用电负荷。

1. The electricity for construction shall be directly connected from the switchgear room, and 50kVA can fully meet the drawdown load requirements.

2、依据用水设备和施工经验，需用水量10m3/h直径50mm

管，就能满足施工用水。

2. Depending on the water equipment and based on the construction experience, the pipe of diameter 50mm with a water flow rate of 10m3/h can meet the construction requirements.

2.3、打井机械及井点设备

2.3. Well drilling rig and well point equipment

打井机械可根据工期要求变更。井点设备是由井点管、连接管、排水主管及抽水设备等组成。具体如下:

The well drilling rig may very according to the schedule requirement. The well point equipment consists of well point pipe, connecting pipe, drain header and pumping equipment. The details are as follows:
