Description
Technical field
The utility model belongs to street lamp engineering technical field, more specifically to a kind of T-shaped floor tubular pile foundation,
Belong to the building structure of foundation engineering.
Background technology
Cement streetlamp foundation is the main flow basis of current urban construction, town and country street lamp installation, in streetlamp foundation engineering
The structure type of use mainly has two kinds, and one kind is cast-in-situ steel reinforced concrete basis, and another is precast hollow pipe pile foundation.Its
In, the manufacturing process on cast-in-situ steel reinforced concrete basis comprises the following steps：
(1) earth and rock works
Foundation pit excavate before should by design path, carry out point hole by position and the depth of design requirement and excavate, it is deep
Error+100.00mm and -50.00mm is spent, hole bottom should be smooth.When the deep error in hole exceedes+100.00mm, ultra-deep part is pressed without exception
Paver grouting treatment, does bed course levelling to designed elevation using C10 grades of fine-stone concretes.When there is underground water on basis, hole should be first excluded
Internal water accumulation, 200mm, thickness 200mm paver C10 grouting pads are gone out per hem width in sole plate lower berth floor space than baseplate width
Layer, basis of then constructing again.
(2) foundation ditch is backfilled
During general earthen backfill, often insert 300mm or so and just tamp once, ram to 200mm or so, and must not mix weeds,
The organic matters such as tree root, forbid mechanical backfill.When backfilling puddle, hole internal water accumulation should be excluded and backfilled again.Backfill should leave depositional gradient
The anti-settling layer of degree, anti-settling layer top area is not less than near coal-mine area；When backfilling general soil, 200mm above ground level is answered.
(3) concrete works
Reinforcement welding joint geometry can use the side bar arc welding of four weld seams, and side strip adoption is identical with soldered reinforcing bar
Steel grade be made with diameter, welding should ensure that two reinforcing bars connect on the same axis.The bottom or side of framework of steel reinforcement are set
Cement mortar bedding block or concrete pad.The foundation bolt relative position on basis, size, absolute altitude are accurate, and take fixation.
Cast-in-place basic template inner surface should be smooth, and seam is tight and ensures the size on basis and casts quality.To ensure concrete
Bulk strength, basic one-time continuous casts completion, is layered vibration compacting, and layer height typically cannot be greater than 25mm, must not stay and apply
Work is stitched.Cast-in-place basic concrete design strength can decompose assembling when reaching 70%, concrete design strength can integral vertical when reaching 100%
Bar.
(4) built-in fitting is embedded
The embedded method using from blinding layer reinforcement placing skeletal support built-in fitting of built-in fitting, first pours base matrix and mixes
Solidifying soil, the method for embedded built-in fitting before initial set, requirement of this method to burying the time is especially high, if embedded too early, by
Certain intensity is not yet reached in concrete, is not enough to bear the gravity of built-in fitting, then built-in fitting will sink；If embedded
Too late, because concrete has solidified, built-in fitting will be unable in Transducers Embedded in Concrete.
(5) triangular stall board is welded
In order to improve basis and the integral rigidity of lamp stand, triangular stall board is welded between basis and lamp stand, so as to improve whole
Body rigidity, meets the ability that structure resists horizontal load.
Cast-in-situ steel reinforced concrete basis has overall performance good, and rigidity is big, shock resistance and good waterproof performance, punches easily
The advantages of, but its operation requires relatively tight, mass of foundation is not easily controlled, and due to needing to consume template, field operation in engineering
Amount is big, and the duration is longer, it is impossible to be immediately subjected to load, and winter construction difficulty is more.Precast hollow pipe pile foundation is first made in factory
Perform, then installed at the construction field (site), have the advantages that easy to make, pile quality is easily controllable, while can save
Template, improves execution conditions when making, raises labour productivity, accelerating construction progress.
But because existing precast hollow pipe pile foundation globality is poor, structure Path of Force Transfer is unreasonable, foundation pile footpath interface
Mismatched with Socket for lamp pole, structure power transmission is unreasonable, reserved skirt mouthful causes basis not reach predetermined strength, therefore is accomplished by
Triangle fixed plate is added above Socket for lamp pole, it is not only dangerous, also unsightly, or even influence pedestrains safety, while the flat horizontal stroke of water resistant
It is poor to load-carrying ability, and streetlamp foundation is mainly just subjected to horizontal cross load, so as to limit precast hollow pipe pile foundation
Promote the use of.Such as, Chinese Patent Application No. discloses basic in a kind of street lamp pole base station for 201620056973.1 patent
Improved structure, this application case includes concrete foundation, lamp stand, cage bar, locating ring, power line penetration pipe and signal wire penetration pipe,
Wherein, lamp stand is hollow columnar structures, and lamp stand is vertically arranged and its lower end is fixedly connected with concrete foundation.Power line penetration pipe
In concrete foundation, concrete foundation upper surface indent, which is constituted, has horizontally disposed and one end open to be located at concrete foundation side
The locating slot of wall, signal wire penetration pipe in the locating slot, power line penetration pipe and signal wire penetration pipe with inside lamp stand
Region is connected.This application is to improve the carrying on basis by setting triangular reinforcing plate between upper flange plate and lamp stand side wall
Ability, but because triangular reinforcing plate is exposed, so that harm is easily produced to pedestrian, and basic lateral load bearing capacity is poor.
Therefore how monolithic reinforced concrete structure streetlamp foundation technology is still generally used in current streetlamp foundation engineering
The above mentioned problem for solving existing precast hollow pipe pile foundation presence is most important for the popularization and application of precast hollow pipe pile foundation.
