Chapter5 Construction scheme 第五章 施工技术方案

一、Construction process flow施工工序流程图

PHC pile sinking process PHC管桩沉桩工艺流程

二、PHC piling route PHC管桩打桩线路

Bitmap according to the design of pile, the engineering pile foundation

according to decorate a pile machine, 3 root pile test it first, after the play,

according to the total floor plan, location close to the building of engineering pile

construction first, try to reduce the vibration and compaction pile due to the

negative impact of the surrounding facilities arrangement principles for piling

process根据设计桩位图,本工程基础桩施打布置1台桩机,3根试桩先施打,

施打完毕后,根据总平面图,靠近建筑物位置的工程桩先施工,尽量减少因

打桩产生的震动和挤土对周围设施的不利影响为打桩流程安排原则。

三、Transportation, hoisting, storage of PHC pile PHC PHC管桩的运输及吊装、

堆放

This foundation piling engineering of the main component is: choose jiashan

county new suitable prefabricated company production of PHC pipe piles, models for

PHC - 500 (100), AB, as shown in the pile construction drawing, the number for 89.本

基础打桩工程的主要构件是:选用嘉善县新顺预制构件公司制作的PHC管桩,

型号为PHC-500(100)AB,详见桩位施工图,数量为89根。

Pile of lifting, transport and storage requirements to meet the technical specification

for the building pile foundation JGJ94-2008 and the pre-stressed concrete pipe pile

"atlas of the 10 g409 regulation. Because of PHC pipe piles for the factory, the

manufacturer in supply transportation and pile driving construction schedule and

supply plan, must work closely, ensure supply quantity and quality of pipe pile.桩的

起吊、运输及堆放的要求要满足《建筑桩基技术规范》JGJ94-2008及《预应力混

凝土管桩》图集10G409中的规定。因PHC管桩为工厂预制,厂方在供应运输

方面与打桩公司的施工进度及供应计划相吻合,必须密切配合,保证管桩的供应

数量及质量。

1、Requirements进桩要求:

Pile driving unit materials and plant materials, both sides must be opened

according to the driving unit into a pile of schedules, strictly implement for pile and

ensure timely supply of pipe pile. Construction personnel to engage in serious

appearance to approach the pile quality check and inspection of quality information,

nonconforming product shall be determined to return.打桩单位材料员与桩厂材料

员,双方必须按打桩单位开出的进桩计划表,严格执行供桩,保证管桩的及时供

应。施工人员要对进场的桩质量进行认真的外观检查及质量资料的检查,不合格

品应坚决退回。

2、Pile inspection requirements管桩验收资料要求:

? Material Certificate and material test report原材料质量合格证和材料复试证

明。

? Quality certificate shall be with the truck管桩出厂应有随车附带管桩出厂合格

证。

? Inspect the outlook and documents of piles根据随车材料单,检验管桩的外观

15

质量及质量文件。

? Provide QA information when necessary提供需方单位要求的有关质量保证资

料。

四、Construction technology of PHC pile PHC管桩的施工技术

1、Site formation and preparation施工场地平整和施工前准备:

Planned area of space and underground obstacles and underground pipeline

should find out and eliminate, there are filled soil region, such as site application of

powder line marked boundaries. To ensure the safety of the pile machine endurance

requirements. For backfill should hold people accountable for monitoring, it is strictly

prohibited to interfuse boulders or obstacles, to ensure the accuracy of pile position.

Before pile driving equipment comes into play, scope of backfill soil with lime

powder marked boundaries warning shots.拟建区域的空间和地下障碍物及地下管

线应查明并清除,如场地有填土区域,应用白粉线标明界限。地耐力要求确保桩

机的安全。如需回填土应派专人负责监护,严禁混入大石块或障碍物,确保打桩

桩位的精度。打桩设备进场前,应将回填土范围用石灰粉标明界限示警。

Water low areas in addition to the drainage, laying crushed stone or construction

waste.积水低洼处除排水外,铺设碎石或建筑垃圾。

Pile driving regional field should be solid level off, the slope is less than 1%.沉

桩区域场地应坚实平整,坡度小于1%。

Pile area should be clearly without water, the lower part of the ground should be

set up open trench and blind ditch drainage.沉桩区域应无明显积水,地势较低处应

设明沟及盲沟排水。

According to GC to provide the control points out of the pile, the site

supervision, check and confirm根据总包单位提供的控制点放出桩位,并由现场监

理复核确认。
