Description
Technical field
The present invention relates to field of track traffic more particularly to a kind of track foundation construction methods.
Background technology
For track construction operation, pile foundation construction is all more important construction link, in pile foundation construction operation
It is generally difficult to ensure that each pile body height flushes in journey.Also, since track project usually requires several months or time several years, for jelly
The pile foundation construction region of the geological conditions complexity such as native, soft thick soil stratum, even if by each pile body construction to substantially sustained height, it is each to manage
With the variation of natural environment different degrees of sedimentation can occur for stake over time, in order to ensure the ride comfort of rail level to carry
High riding comfort, it is necessary to reduce the subsiding extent of pile foundation as far as possible.
As Chinese utility model patent (204455724 U of CN) discloses a kind of tool of Deep Thick Soft Ground Area roadbed track
Body construction method, including：
Step 1, Soft Soil Area construct span centre prefabricated pile and across end prefabricated pile.
Step 2 is constructed across the plain concrete bed course of end supporting beam lower part.
Step 3 is bound for, across reinforcing bar in end carriage, concreting being used in combination to be formed across end supporting beam across end supporting beam.
Step 4, by reinforcing bar in the plate in reinforcing bar in the span centre beam of span centre supporting beam and the embedded support plate of span centre sleeper into
Row is staggeredly bound.Prefabricated tie block 4 is flowed into bar connecting by anti-fan, and is positioned on the bar construction bound.
Then span centre supporting beam and the embedded support plate formed by integrally casting of sleeper are molded by step 5, accurate adjustment track.After pouring
The embedded support plate of sleeper end set in across end prefabricated pile on.
Step 6, according to same sequence construction second segment, and by the end of the adjacent embedded support plate of two sections of sleeper
Be set to first segment across end prefabricated pile on.The sleeper of the end and second segment of the embedded support plate of sleeper of wherein first segment
There are a deformation joints between the end of embedded support plate.It the end of the embedded support plate of sleeper and is used between holding precast beam
The Bituminous hemp fiber of 5cm thickness is filled.It is laid with each section successively according to above-mentioned steps.
Step 7 is laid with pave-load layer in the embedded support plate of sleeper laid, completes roadbed track.
Although the concrete construction method of above-mentioned Deep Thick Soft Ground Area roadbed track is can to reduce ground to a certain degree heavy
Drop, still, the concrete construction method of above-mentioned Deep Thick Soft Ground Area roadbed track is before accurate adjustment track and adjustment not yet in effect is prefabricated
The mounting height of tie block, irregularity when this will cause rail level to be laid with.And due to only constructing between prefabricated pile and supporting beam
Plain concrete bed course, this just causes to lack enough bonding strengths between prefabricated pile and supporting beam, thus cause entire roadbed track
Resistance to plucking and anti-pressure ability it is not satisfactory.In addition, this construction method also has great in constructing amount, concreting amount is big to lack
It falls into, is unfavorable for energy conservation and environmental protection.
