Description
Technical field
The present invention relates to the method for construction of a kind of bridge, be specifically related to a kind of bridge construction method adopting bridge prefabrication cushion cap.
Background technology
Cushion cap refers to as bearing, be distributed the load transmitted by pier shaft, the reinforced concrete platform connecting each stake top arranged at pile foundation top.Cushion cap is that stake contacts part with post or pier.Cushion cap is several, and even tens piles link together formation pile foundation.Cushion cap is divided into high-rise pile cap and low pile cap: low pile cap is generally embedded in soil or part is nuzzled in soil, and high-rise pile cap generally bassets or the water surface.
Along with us national economy, scientific and technological and social development, the science of bridge building project of increasing marine environment is implemented, but owing to off-lying sea built environment is complicated, inclement condition, construction cost is high, causes that bridge construction difficulty of construction is big.In this context, in order to avoid the hydraulic pressure excessive compression to the cross-section of river, it is necessary to marine bridge bearing platform is imbedded sea bed, thus buries bed process and arise at the historic moment.Bed process bridge prefabrication cushion cap is buried in employing, it is possible to suspended deck structure embedment sea bed big for current obstruction area is reduced water blocking rate, and prefabricated main force structure guarantees construction quality on the coast simultaneously.Scene forms dry working environment by antipriming, effectively connects prefabricated cushion cap and pile foundation, implements main muscle spreading, colligation distributing bar, build the concrete of connecting portion, it is ensured that the two effectively connects.
But, implement so simple in not imagining.Owing to provide dry working environment, this is for implement science of bridge building project across the sea, difficulty is quite big, even if providing dry working environment, also quickly to construct bury the prefabricated cushion cap of bed process and and pile foundation between connecting structure, the most important quality being to ensure that bridge so that it is can guarantee that normal traffic quality.
Summary of the invention
It is an object of the invention to provide a kind of beam prefabricated cushion cap of quick, efficient and easy cross structure and pile foundation, and ensure that bridge intensity and then ensure that the bridge construction method of bridge quality.
Technical scheme is as follows:
A kind of bridge construction method adopting bridge prefabrication cushion cap, it is characterised in that comprise the following steps:
Step 1: build the pile foundation of required bridge；
Step 2: after treating pile foundation construction, lifts sinking by bridge prefabrication cushion cap and puts in place, enables the sealing capsule being arranged in the default groove in described bridge prefabrication cushion cap base plate place, forms dry working environment in the back pouring hole of described bridge prefabrication cushion cap；
Step 3: be welded and fixed described pile foundation and described bridge prefabrication cushion cap, and by the main muscle spreading in described bridge prefabrication cushion cap back pouring hole, colligation distributing bar, casting concrete；
Bridge prefabrication cushion cap of the present invention, is provided with back pouring hole in the position corresponding with pile foundation, and described back pouring hole sidewall is provided with shearing resistance groove；And the base plate place of described bridge prefabrication cushion cap is provided with preformed groove, in groove, it is provided with sealing capsule, after enabling described sealing capsule, dry working environment can be formed in funnel in the rear.Wherein, in described back pouring hole, it is provided with main muscle, for when being welded and fixed with pile foundation by described bridge prefabrication cushion cap, by main ribs spreading, colligation distributing bar casting concrete, so that described bridge prefabrication cushion cap is effectively connected with pile foundation.
Main ribs is by reinforcing bar 70-76 part of following weight, 3-alpha-hydroxyl-5-androstene-17-ketone 11-17 part, cholesteryl linolenate 9-13 part, 1-[(1-pyrrolidine formyl) methyl]-4-(3, 4, 5-trimethoxy cinnamoyl) piperazine maleate 3-5 part, 3, 4-dimethoxy-acetophenone 7-13 part, PhosphorodichloridicAcid Acid Phenyl Ester 2-4 part, NO free radical piperidine alcohols 6-10 part, 16a, 17a-epoxy-3b-monohydric pregnant-5-alkene-20-ketone 15-19 part, dimethyl [(E)-4-methylamino-4-oxo but-2-ene-2-base] phosphate ester 4-6 part, S-carboxyethyl isothiouronium chloride 3-5 part is by rolling, extrusion, casting technique is made.
Preferably, in order to make bridge have higher intensity, the parts by weight of raw materials proportioning of main ribs is: reinforcing bar 73 parts, 3-alpha-hydroxyl-5-androstene-17-ketone 14 parts, cholesteryl linolenate 9 parts, 1-[(1-pyrrolidine formyl) methyl]-4-(3, 4, 5-trimethoxy cinnamoyl) piperazine maleate 5 parts, 3, 4-dimethoxy-acetophenone 10 parts, PhosphorodichloridicAcid Acid Phenyl Ester 2 parts, NO free radical piperidine alcohols 10 parts, 16a, 17a-epoxy-3b-monohydric pregnant-5-alkene-20-ketone 17 parts, dimethyl [(E)-4-methylamino-4-oxo but-2-ene-2-base] phosphate ester 4 parts, S-carboxyethyl isothiouronium chloride 5 parts.
