Description
Technical field
The present invention relates to technical field of bridge construction, and in particular to a kind of construction method of bottom bridge pile foundation.
Background technology
At present, it when pile foundation construction is carried out in muck soil environment coastal, riverine, along the lake, is mostly stirred using soil cement
Mix pile-making method construction.Cement mixing method be by the use of cement as curing agent, by Mixing Machine, ground depths by weak soil and
Curing agent action of forced stirring is chemically reacted using a series of physical generated between curing agent and weak soil, makes weak soil scleroma into tool
There is the high-quality ground of globality, water stability and some strength.
The basic principle of soil-cement is the physical-chemical reaction process based on soil-cement, it and concrete hardening
Mechanism is different, and since cement mixing content is few, cement is with certain active medium -- and native is reacted under, setting rate
It is relatively slow, and complexity is acted on, after cement hydrolysis generates various hydrates with aquation, ion exchange occurs again for some and granule is turned into
With and pozzolanic reaction, greatly improve soil-cement body intensity.But due to cement soil material itself, energy is carried
Power is subject to certain restrictions, and its durability is also not as good as other pile-type, and intensity is met the requirements during construction, but as the time pushes away
It moves, is particularly subject to the influence of sulfate ion, magnesium ion and calcium ion etc. in surrounding seawater, intensity can greatly be beaten with the time
Discount brings hidden danger to the engineering in pile foundation.
Invention content
The purpose of the present invention is to provide a kind of construction methods of water-bed bridge pile foundation, can effectively solve background technology
In the technical issues of being previously mentioned.
To achieve the above object, the present invention provides following technical solution：
A kind of construction method of bottom bridge pile foundation, which is characterized in that include the following steps：
(1) water-bed Bridge Pile basal plane leveling, cleaning and water-bed bridge pile foundation planar survey operation：It is clear using underwater diver
Reason and the method for underwater demolition form work surface after excavation cleaning, as water-bed Bridge Pile basal plane, and complete water-bed bridge pile foundation
Planar survey operation；
(2) it using jet drill rig construction cement mixing method, and is carried out using cement mortar spray regime, the density of cement mortar
It controls as 1.1-1.2kg/cm3；
(3) pile pile stake holes is formed using steel pile casting is squeezed to cement mixing method center, later to pile pile stake holes
Inner wall is tamped, and the steel pile casting uses thickness to be made for the steel plate of 0.8-1mm；
(4) stake will be sunk to using the pile sinking casing static pressure or hammering for being set to its inside with the pile pile of annular steel pile tip
In hole and reach design position, extract and pile pile is obtained after pile sinking casing, the verticality of pile pile is within 0.5% and its position deviation
15cm is not greater than, the pile sinking casing is made of stainless steel；
(5) hard engineering plastic heavy wall Grouting Pipe in the cement mixing method of pile pile side is set, and is led to foundation pit
Except, lateral surface 3-4cm of the Grouting Pipe apart from cement mixing method.
Preferably, lateral surface 4cm of the Grouting Pipe apart from cement mixing method.
Preferably, the steel pile casting uses thickness to be made for the steel plate of 1mm.
Compared with prior art, the beneficial effects of the invention are as follows：
The water-bed bridge pile foundation made using the construction method of bridge pile foundation water-bed in the present invention is with safety and reliably
Property it is high, and greatly improve its durability under seawater eroding, compared to traditional cement mixing method, the water in the present invention
Bottom bridge pile foundation service life can be longer.
Specific embodiment
With reference to the embodiment technical solution that the present invention will be described in detail, but protection domain is not limited thereto.
Embodiment one：
A kind of construction method of bottom bridge pile foundation, includes the following steps：
(1) water-bed Bridge Pile basal plane leveling, cleaning and water-bed bridge pile foundation planar survey operation：It is clear using underwater diver
Reason and the method for underwater demolition form work surface after excavation cleaning, as water-bed Bridge Pile basal plane, and complete water-bed bridge pile foundation
Planar survey operation；
(2) it using jet drill rig construction cement mixing method, and is carried out using cement mortar spray regime, the density of cement mortar
It controls as 1.1-1.2kg/cm3；
(3) pile pile stake holes is formed using steel pile casting is squeezed to cement mixing method center, later to pile pile stake holes
Inner wall is tamped, and the steel pile casting uses thickness to be made for the steel plate of 0.8-1mm；
(4) stake will be sunk to using the pile sinking casing static pressure or hammering for being set to its inside with the pile pile of annular steel pile tip
In hole and reach design position, extract and pile pile is obtained after pile sinking casing, the verticality of pile pile is within 0.5% and its position deviation
15cm is not greater than, the pile sinking casing is made of stainless steel；
(5) hard engineering plastic heavy wall Grouting Pipe in the cement mixing method of pile pile side is set, and is led to foundation pit
Except, lateral surface 3-4cm of the Grouting Pipe apart from cement mixing method, between Grouting Pipe and the lateral surface of cement mixing method
