Description

Bank revetment heightening construction method is refuted in active service
Technical field
The present invention relates to reinforcing, heightening construction methods that bank revetment is refuted in a kind of active service.
Background technique
River waterway revetment engineering is to protect river bank from water flow, stormy waves invasion and wash away taken engineering measure. A large amount of built Shore protection design standards are low, and constantly corroding and washing away by seawater for a long time, lose its enforcement gradually and support Imperial sudden and violent tide, wave, water flow invasion, protect the effect of seashore inside and outside harbour.The active service shore protection so huge in face of quantity, all pushes away It rebuilds neither science and wastes man power and money.Therefore, it is necessary to be increased active service revetment, reinforced, structure safety can be met And real requirement, such active service revetment is increased, reinforcing engineering is in growth trend year by year in recent years.
Mainly there are reconstruction method in situ, bored concrete pile method for strengthening, mini pile method for strengthening etc. to the processing of active service revetment at present, when When taking reconstruction method in situ, original disease barricade is removed, revetment is built again according to new specification, needs to carry out large area Excavation, cutting depth is big, long construction period and cost is high;Bored concrete pile method for strengthening directlys adopt punching in bank side position Bored concrete pile is reinforced, and larger to the disturbance of active service revetment in its punching operation, there are biggish security risks in construction;It is miniature Stake method for strengthening is relatively new, and it is convenient to construct, but sexual valence is poor.
Summary of the invention
The purpose of the present invention is to provide a kind of regulations of combination active service revetment bar planting veneer to increase and add prefabricated anti-slop serrations Wall refutes bank revetment to status using integrally-lifting sliding punching block and is widened, increases, and by presstressed reinforcing steel by revetment Body and the cellular concrete of bank side backfill are linked to be the construction method of an entirety, can be refuted with active service the Defects Treatment of bank revetment with And in transformation and upgrade construction.
To realize the above-mentioned technical purpose, the invention adopts the following technical scheme:
Bank revetment heightening construction method is refuted in a kind of active service, comprising the following steps:
1) preparation of construction: machinery, material, personnel's that organizing construction needs etc. marches into the arena, and carries out to former revetment surface scarce Detection is fallen into, and uses the cementation of fissures, the modes such as outsourcing carbon cloth repair former shore protection crack.
2) antiskid pile driving construction: the injection precast square pile before status revetment is installed by the way of planting stake.Precast square pile top Prefabricated anti-skidding key-wall is set, is connected between prefabricated anti-skidding key-wall by tongue and groove;Install reinforced mesh, and with precast square pile top The connection of portion's reserving rib, concreting are integral.When pouring, in the sliding rail of design position Slip-reserved punching block.
3) former shore protection bar planting, drainpipe spreading: former shore protection includes bottom plate, former revetment, drainpipe etc., with spreading drainpipe Spreading is carried out to former shore protection drainpipe, and bar planting and the newly-increased part reinforcing bar binding connection of shore protection are carried out to former revetment.
4) increase bank protection construction newly: side template is pressed in installation, is connect by screw rod with former revetment;It is subsequently mounted the side form that borders on the river Plate is made of sizing tripod, operating platform, steel plate etc.;It borders on the river after side template is installed and rotates collapsible form, with bank side form Plate is connected by screw rod;Casting concrete after the completion of formwork erection forms shore protection and increases part newly.Demoulding Shi Xiansong collapsible form screw rod, Bank side template is removed again, jacks the side template that borders on the river, demolition template finally by plate jacking device, template is slid onto down after unclamping One construction section.The newly-increased part of shore protection is conserved in time after demoulding.
5) foam concrete is constructed: the prefabricated ribbed plate stake (26) of elder generation's injection, sheet pile at design position on rear side of the status revetment Floor is set, preformed hole is reserved on rib of slab, the soil body is excavated in classification, excavates one layer with one layer of steel pipe support supporting, excavates and complete Variable diameter Grouting Pipe is installed through preformed hole afterwards, presstressed reinforcing steel is reserved to newly-increased shore protection and carries out spreading, installs foam concrete steel Pouring for foam concrete is carried out after muscle mesh sheet.Slip casting then is carried out to variable diameter Grouting Pipe, and tensioning, envelope are carried out to presstressed reinforcing steel Anchor.It finally pours and newly pours road surface.
Further, in step 4) plate jacking device by fashioned iron reaction beam, steel shoe, the groups such as jack, running gear At running gear includes bearing and idler wheel composition, and lift steel pulley is fixed on fashioned iron reaction beam, and fashioned iron reaction beam is fixed In sizing the horizontal channel steel of tripod on and be linked as entirety, while be arranged auxiliary jack auxiliary provide top lift.
The present invention is that bank revetment rebuilding construction technology is refuted in comprehensive active service, is added in conjunction with the regulation of active service revetment bar planting veneer It is high with add prefabricated anti-skidding key-wall, bank revetment is refuted to status using integrally-lifting sliding punching block and widened, increase, and is led to It crosses presstressed reinforcing steel and the cellular concrete that wall body for revetment and bank side backfill is linked to be an entirety.The present invention have the characteristics that it is following and The utility model has the advantages that
(1) prefabricated anti-skidding key-wall is increased and added to this engineering method by the regulation of active service revetment bar planting veneer, and backfills in bank side It is insufficient to solve the problems, such as that bank shore protection wall construction, secure context are refuted in active service for concrete.
(2) prefabricated anti-skidding key-wall is increased and is added in active service revetment bar planting veneer regulation.The prefabricated side of injection before status revetment Stake, precast square pile top are arranged prefabricated anti-skidding key-wall, are connected, antiskid effect is good.
(3) for status revetment wall with after basic bar planting, drainpipe spreading, installation integrally-lifting slides punching block, pours side Face and increase concrete.Sliding system by whole punching block, construct convenient, the duration by tripod of being formed, lift steel pulley composition It is short.
(4) design position first breaks sheet pile with ribbing after former status revetment, and sheet pile bottom pours bent cap and is linked as entirety, plate Stake embedded steel tube, newly pour and former revetment wall on bar planting, pilot hole built-in connection install stay bolt lever when excavating, excavation Grouting Pipe, and casting concrete are set after the completion, improve the bearing capacity and globality of structure.
(5) using foam concrete to backfilling after wall, have the characteristics that light weight, intensity are high, speed of application is fast, it is real Border application effect is good.
(6) increasing shore protection template, screw rod, nut etc. newly can sufficiently reuse, and greatly improve construction efficiency, saved and applied Work cost.
