Background technology:
Along with deepening continuously of National Macroscopic economic adjustment, the expressway construction market of China is flourish, and at the end of cut-off 2011, speedway total kilometrage has reached 8.5 ten thousand kilometers, is sure to occupy the second in the world.According to the actual conditions of each department, in expressway construction process, adopt the multiple construction modes such as newly-built, renovating and enlarging, overhaul.At present in reorganization and expansion road event, particularly in major repair project construction, after roadbed, heavy resurfacing, grade elevation is caused to promote, the relative altitude on original guardrail and road surface is caused to reduce, cause larger potential safety hazard to traffic flow, the current safety of vehicle and traffic safety facilities technical specification and national standard cannot be ensured, removed again that construction cost is high, operation is numerous and diverse, loss due to spoiled work in the past.
Summary of the invention:
The object of this invention is to provide a kind of highway extension project and overhaul engineering guardrail pile connection construction method and pile extension component, cost of manufacture reduces, and improves efficiency of construction.
Above-mentioned object is realized by following technical scheme:
A kind of highway extension project and overhaul engineering guardrail pile connection construction method, the method comprises the steps: the column caliber size according to original highway barrier, the steel-pipe welding or cold working that are not less than former column strength are formed the pile extension component that caliber is variable cross-section, variable-section steel pipe is utilized to be connected with former column as pile extension component, with hydraulic pile driver after pile extension, pressure pile sinking is carried out according to design and construction size, in pile driving process, elevation and vertical bury pipe is controlled well, until meet design requirement by level gauge and vertical bury pipe tester, after pile sinking, pile extension component and former upstanding studs hole high-strength bolt are fixed locked, make former column and pile extension part become overall, reach design by force intensity, finally obstruction block or bracket are installed, by high-strength bolt, guardrail board are installed, the described diameter of pile extension component and the determination of wall thickness: the former material as pile extension component should be identical with described former column material, its thickness and diameter are tried one's best equal or are not less than, to ensure its intensity, the determination of the former material length of described pile extension component, be connected for guaranteeing the former leghole position reached described in utilization, and realize guardrail board hang after meet steel guard rail acceptance criteria, former material length should >=road surface increase height+pile extension press down stroke+former leghole distance+pitch-row edge length, after confirmed standard size, intercept corresponding steel pipe length, by mold lathe and special-purpose machinery, be placed between hydraulic pressure utensil and fetal membrane, carry out in variable cross-section cold working process, balanced, slowly afterburning, prevent from causing plastic failure, the pile extension component of described variable cross-section cold working made carries out punching press pore-forming according to the design attitude of drawing, and carries out preservative treatment, the stake bit plane of described pile sinking arranges revision, utilizes transit to carry out linear setting-out demarcation, and level gauge controls elevation, vertical bury pipe tester controls the vertical bury pipe of pile extension, meter ruler controls stake column pitch, is partially worth demarcation, to control in the process of pile sinking in former stake position, described pressure pile sinking is according to direction, position, the hole principle consistent with former column by described pile extension component, small bore stands on concentric position on described former column down, stake machine tup evenly exerts a force by a small margin from heavy in section and presses down, pile extension component is slowly moved down along former column inwall until become large locked by frictional force because of cross section, tup increases pressure, operating personnel are according to the plan-position of setting-out and vertical bury pipe, regulate and control in stake sinking watching, ensure that plan-position and vertical bury pipe meet the demands, according to altitude data, slowing down stroke close to during design altitude 50 ㎜, until design altitude stops piling, tup is mentioned, carry out the pile sinking of next fence upright.
Described highway extension project and overhaul engineering guardrail pile connection construction method, according to the size of design drawing, after pile sinking, the hole that former rail pile column hangs obstruction block just in time overlaps with the lower marginal pore of described pile extension component, be fastenedly connected with standard high-strength bolt, make the pile extension part of pile extension component and described former column become overall.
Beneficial effect:
Make full use of original guardrail facility and engineering material, saved the expense occurred because of old guardrail facility dismounting, transport and storage, particularly saved the significant investment occurred because traffic environment requirement again lays guardrail.
Utilize adapter technology that column entire length is increased, under the effect of hydraulic pile driver, make the corresponding increase of the following buried depth in fence upright road surface, add resistance to overturning and the safety in utilization of guardrail.
Construct simple and practical, be easy to operation, little, the unified batch production of pile extension material profile, safer under the environment be open to traffic; Squeeze into stroke short, save the engineering time; Be easy in construction control elevation and straight degree, what ensure that after construction is linearly attractive in appearance.
The enforcement of guardrail pile connection construction technology and utilization, be embodied directly in every root post saving steel weight.Relatively again construct, pile extension consumes the long 45cm(of steel and raises 11cm calculating by road surface), the long 2150cm(design standard of construction stake again), when caliber wall thickness is identical, every pile saving steel is 80%, and direct cost will reduce by 80%; From indirect angle, same pile column, more than pile pulling expense piling expense, by the equal calculating of expense, is equivalent to piling twice.Pile connection construction takes saving more than 90%.Because pile extension operation is simple, guardrail board can shipped off-site after removing, and cross construction is installed, and saves a large amount of transports and has bad luck expense; From economically total, because the duration is short, blocked for road construction time is short, reduce the probability had an accident in construction, improves road operation ability simultaneously, shortens the haulage time of public vehicles, improve the economic benefit of society greatly.
