Description
Technical field
The present invention relates to the weight installation methods that a kind of rigid structure of bridge more particularly to a kind of rigid structure of bridge close up.
Background technology
The rigid structure closure segment of traditional bridge and abutment lapping construction operation, typically use heap earth bag, water tank or water packet into
Row closure segment and abutment lapping construction ballast conversion process；Its ballast method is more original, and the ballast point in work progress is more, makees
Industry is cumbersome and work efficiency is low.Secondly heap earth bag, water tank or the water packet used carries out closure segment and the conversion of abutment lapping construction ballast
The formation of operation is lack of standardization, it is difficult to meet the job requirements of site safety, civilized construction；This be mainly the rigid structure closure segment of bridge and
The ballast conversion process mode and construction technology that abutment lapping construction operation uses need to improve.
Invention content
In view of the above shortcomings of the prior art, the technical problem to be solved by the present invention is to：It is rigid how a kind of bridge is provided
The weight installation method that structure closes up.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions：
A kind of weight installation method that the rigid structure of bridge closes up, which is characterized in that include the following steps：First, it is applied in Hanging Basket
Work process is symmetrically installed ballast flat car temporary track 6 and railcar to after closing up fragment position, in two pier location top bridge floors
Shelves 7 are fixed temporary track 6 on the position of bridge floor longitudinal direction using foundation bolt, are fixed in 6 end of ballast flat car temporary track
Attachment rail car stop 7；Then, the bridge floor right over two bridge piers installs ballast flat car a and ballast flat car b, flat in ballast
6 tip position of wooden handcart temporary track installs draft gear 9；It is segmented connection haulage cable 10, shape through rigid 3 break-through of structure construction hanging basket
The weight constructed at the closure segment of the rigid structure of bridge.
Its main feature is that：Using symmetrical weight form, can after closure segment and the docking of abutment bond end fast debugging, into
It constructs after row configuration ballast.In concrete placings, the closure segment of ballast flat car a and the rigid structure of the above-mentioned bridges of ballast flat car b is constructed
Method uses symmetrical weight form, can be formed after mounting with easily functional device of walking；It may be implemented in concrete placings
When, configuration ballast vehicle can be moved as the increase of concrete placings amount is gradually rear steadily, realize the gradually conversion of ballast；It can ensure that rigid structure closes
The quick formation for holding together section and abutment bond end debugging docking process, can meet the job requirements of site safety, civilized construction；It is easy to
Reach the required construction technology mass effect under general condition.
Further feature is：It refers to the process of when concrete is gradually poured to end, and realization that the ballast, which is gradually converted,
The ballast weight of closure segment or abutment bond end is gradually decreased as the process of O.
Compared with the existing technology compared with the weight installation method that the rigid structure of bridge of the present invention closes up, which has advantage, is：
1, weight can be formed after mounting with easily functional device of walking；
2, rigid structure closure segment can be easily realized in concrete placings, and ballast flat car a and ballast flat car b are with concrete placings amount
Increase gradually steadily after move, realize the gradually conversion of ballast；
3, after can ensure that rigid structure closure segment and the debugging of abutment bond end, rigid structure closes up the quick formation of docking process, can meet existing
Field safety, the job requirements of civilized construction；Easily reach the required construction technology mass effect under general condition.
4, easy to operate, it is convenient to carry out.

Specific implementation mode
The weight installation method of the present invention is made into one with reference to a kind of section constructing method that closes up of the rigid structure of bridge
The detailed description of step.
A kind of technical solution for closing up section constructing method of the rigid structure of bridge includes the following steps：
（1）It prepares：According to production engineering specifications, symmetrical weight is carried out --- ballast flat car a's and ballast flat car b adds
Work prepares and the preparation of ballast flat car temporary track 6, track car stop 7, draft gear 9 and haulage cable 10；
（2）Installation（As technical scheme of the present invention）：First, it constructs according to a kind of closure segment for the rigid structure of bridge accordingly invented
The symmetrical weight form of method, it is symmetrical in two pier location top bridge floors in cradle construction process to after closing up fragment position
Ballast flat car temporary track 6 and track car stop 7 are installed, temporary track 6 is fixed using foundation bolt bridge floor longitudinal direction position
On and attachment rail car stop 7；Installation combination ballast vehicle 8 contains a, b, and installs draft gear 9 at such as positions Fig. 2 both ends（It leads
Draw electric block）；It is segmented connection haulage cable 10 through rigid 3 break-through of structure construction hanging basket（It is being held in ballast flat car temporary track 6
The pulley installed at head is set with haulage cable 10）, form the walking weight of the closure segment construction of rigid structure；
（3）It in work progress, is provided according to arrangement and method for construction, first, the abutment overlap joint end construction of rigid structure is carried out, when ballast tablet
