Abstract
The present invention relates to deep basal pit soft soil foundation construction, more particularly to deep basal pit soft soil foundation manual digging pile construction.A kind of deep basal pit soft soil foundation steel pile casting manual digging pile construction method, it includes：Step one, the steel reinforcement cage of outside Large-diameter Steel casing and the inside steel bushing with bellend is made；Step 2, vibration hammer or steel sheet pile manipulator vibration dip set outside steel pile casting；Step 3, sets steel pile casting inner bottom part blotter；Step 4, installs the steel reinforcement cage with bellend with internal steel bushing；Step 5, one-time-concreting bottom concrete；Step 6, it is secondary to pour top concrete；Step 7, backfill between outer steel pile casting and interior firm sleeve；Step 8, pulls out interior steel bushing and outer steel pile casting；Step 9, pile top reinforcing bar cleaning is normally carried out structure construction after being connected with basic bottom reinforced slab.The method of the present invention can form the pile foundation that pile foundation bottom carries bellend, be effectively improved its weight capacity, it is ensured that safety and the surrounding enviroment adverse effect of construction period.
Description
Technical field
The present invention relates to deep basal pit soft soil foundation construction, more particularly to deep basal pit soft soil foundation manual digging pile construction.
Background technology
In deep foundation pit of soft soil foundation engineering, the application of pile foundation is relatively broad, but when carrying out pile foundation construction in such region, using common pile tube or cast-in-situ bored pile because its diameter is smaller, because load-bearing requirements need the quantity and length of the pile foundation set than larger, and soft soil foundation engineering property is poor, common pile foundation equipment construction is limited, and difficulty of construction is higher.If piling is more difficult in the soft base deep basal pit after excavation.
The content of the invention
It is contemplated that overcoming the defect of prior art, there is provided a kind of deep basal pit soft soil foundation steel pile casting manual digging pile construction method.The method of the present invention can form the pile foundation that pile foundation bottom carries bellend, be effectively improved its weight capacity, it is ensured that the safety and surrounding enviroment of construction period is unaffected.
A kind of deep basal pit soft soil foundation steel pile casting manual digging pile construction method of the present invention, it includes：
Step one, the steel reinforcement cage of outside Large-diameter Steel casing and the inside steel bushing with bellend is made；
Step 2, vibration hammer or steel sheet pile manipulator vibration dip set outside steel pile casting；
Step 3, sets steel pile casting inner bottom part blotter；
Step 4, installs the steel reinforcement cage with bellend with internal steel bushing；
Step 5, one-time-concreting bottom concrete；
Step 6, it is secondary to pour top concrete；
Step 7, backfill between outer steel pile casting and interior firm sleeve；
Step 8, pulls out interior steel bushing and outer steel pile casting；
Step 9, pile top reinforcing bar cleaning is normally carried out structure construction after being connected with basic bottom reinforced slab.
The present invention can form the pile foundation that pile foundation bottom carries bellend, be effectively improved its weight capacity, reduce soft soil foundation pile foundation consumption.Present invention process principle is simple, safe and reliable, influences small to surrounding enviroment, is easy to operation.The steel bushing of the present invention is repeatable to be used in turn, and advantageously reduces cost.
Embodiment
A kind of deep basal pit soft soil foundation steel pile casting manual digging pile construction method of the present invention, first by the steel pile casting of major diameter（Outer casing）Set using vibration hammer or steel sheet pile manipulator vibration dip to precalculated position, then manually, small-sized machine coordinate etc. measure the earthwork in steel pile casting is excavated, the earthwork of steel pile casting bottom should reserve certain thickness when excavating, it is ensured that the soil stabilization of steel pile casting inner bottom part, then lay blotter；Again bellend is carried by what is made（Steel reinforcement cage lower end）With steel bushing（Inner sleeve）Steel reinforcement cage be attached in Large-diameter Steel casing, then pour a steel reinforcement cage lower end（Bellend）Concrete；It is secondary when one-time-concreting concrete is pre-hardening to pour steel bushing（Inner sleeve）Interior concrete；Pour after the completion of concrete the backfill between outer steel pile casting and interior steel bushing；Pull out internal steel bushing；Pull out outside steel pile casting.The pile foundation that pile foundation bottom carries bellend can be thus formed, is effectively improved its weight capacity, it is ensured that the safety and surrounding enviroment of construction period is unaffected.
