Abstract
The present invention discloses cement asphalt (CA) mortar vertical formwork type pouring method, and belongs to the field of building construction technology. The pouring method includes the following steps: installing support screws on the pedestal, spreading track boards supported with the support screws, setting vertical formworks outside the track boards, pouring CA mortar, and removing support screws and formworks after 24 hr and reaching strength of 0.1 MPa. The present invention is used for jointing between the track board and the pedestal, and can reach the close jointing and long service life of the track, and produce certain regulating and buffering effect.
Description
Technical field
The present invention relates to a kind of constructional materials, be specifically related to a kind of method for filling of mortar.
Background technology
Along with the development of society, the common target of pursuing in high-speed railway transportation having become countries in the world.For the requirement of the high stationarity that adapts to high-speed railway, high-durability, comfortableness, need to adopt and the ballastless track of the few maintenance of development.The rail that ballastless track adopts is directly installed on the track plate, and track slab pavement is on footing foundation.Because footing foundation and track plate all are steel concrete builds and form, both can not direct closely connected joint, therefore, need add between footing foundation and track plate and adjust layer, makes both closely connected joints.
Summary of the invention
The objective of the invention is to: provide a kind of cement asphalt mortar that will have adjustment, shock-absorbing capacity to be poured into method between footing foundation and the track plate.
Technical scheme of the present invention is: 1, a kind of cement asphalt mortar vertical mould type pouring method mainly contains following steps:
A, carrying bolt is installed in track plate side; Carrying bolt propped up stand on the footing foundation, and the track plate is adjusted to desired location;
B, on footing foundation, be provided with template and surround the track plate outside, and make and form chamber between track plate and the footing foundation, leave the wide eye split of 2～4mm between template and track plate side;
C, the mortar that will mix and stir inject in the described chamber from the cement asphalt mortar perfusing hole on the track plate, reach 70mm up to track edges of boards cement asphalt mortar influx height, and after at the bottom of the complete overlay, perfusion finishes;
The perfusion of d, cement asphalt mortar finish reach 0.1MPa through 24 hours and intensity after, in time remove carrying bolt and template.
The cement injection asphalt mortar, bituminous mortar should carry out under 5～25 ℃ environment temperature.
Cement asphalt mortar if be placed in the buffering perfusion jar, must be maintained to few 10～30 rev/mins mixing speed after mixing and stirring.
After described carrying bolt and the form removable, by designing requirement finishing cement asphalt mortar layer edge.
Paste the section of rubber spacer in track plate bottom, the thickness range of cement asphalt mortar layer is 30～100mm; The thickness range of other section cement asphalt mortar layers at the bottom of the track plate is 40～100mm.
On the lifting nut of carrying bolt mounting rail guidance tape side.
The invention has the beneficial effects as follows: can be so that track plate and footing foundation tightly engage, and have and adjust and the buffering effect, make track have certain elasticity simultaneously, thereby can strengthen the application life of track.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is the vertical view of Fig. 1;
Wherein, Reference numeral is, 1 is footing foundation, and 2 is the track plate, and 3 is the CA screed, and 4 is carrying bolt, and 5 is connecting bolt, and 6 is template, and 7 is eye split, and 8 is CA mortar injection mouth, and 9 are the lifting nut.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of CA mortar formwork erection formula method for filling mainly contains following steps:
A, on the lifting nut of track plate 2 sides, carrying bolts 4 are installed by connecting bolt 5; 4 of carrying bolts are stood on the footing foundation 1, and the track plate is adjusted to desired location;
B, on footing foundation, be provided with template 6 and surround track plates 2 outsides, and make and form chamber between track plate 2 and the footing foundation 1, leave the wide eye split of 2～4mm 7 between template and track plate side;
C, the mortar that will mix and stir inject in the described chamber from the CA mortar injection mouth 8 on the track plate 2, reach 70mm up to track edges of boards CA mortar injection height, and after at the bottom of the complete overlay, perfusion finish;
D, CA mortar injection finish reach 0.1MPa through 24 hours and intensity after, in time remove carrying bolt 4 and template 6.
In addition, perfusion CA mortar should carry out under 5～25 ℃ environment temperature.The CA mortar if be placed in the buffering perfusion jar, must be maintained to few 10～30 rev/mins mixing speed after mixing and stirring.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of CA mortar formwork erection formula method for filling mainly contains following steps:
A, on the lifting nut 9 of track plate 2 sides, carrying bolts 4 are installed by connecting bolt 5; 4 of carrying bolts are stood on the footing foundation 1, and the track plate is adjusted to desired location;
B, on footing foundation, be provided with template 6 and surround track plates 2 outsides, and make and form chamber between track plate 2 and the footing foundation 1, leave the wide eye split of 2～4mm 7 between template and track plate side;
C, the mortar that will mix and stir inject in the described chamber from the CA mortar injection mouth 8 on the track plate 2, reach 70mm up to track edges of boards CA mortar injection height, and after at the bottom of the complete overlay, perfusion finish;
D, CA mortar injection finish reach 0.1MPa through 24 hours and intensity after, in time remove carrying bolt 4 and template 6;
E, by designing requirement finishing CA screed 3 edges.
In addition, perfusion CA mortar should carry out under 5～25 ℃ environment temperature.The CA mortar if be placed in the buffering perfusion jar, must be maintained to few 10～30 rev/mins mixing speed after mixing and stirring.
Because some section of vibration damping type track plate bottom is pasted rubber spacer, pastes the section of rubber spacer in the bottom, the thickness range of CA screed 3 is 30～100mm; The thickness range of other sections CA screed 3 at the bottom of the track plate is 40～100mm.
