Problems solved by technology

During the concrete pouring process of the box girder on the top of the pier, the pre-buried pipes are often blocked due to the carelessness of the workers, which makes the grouting work difficult
[0003] The fixing method between the grouted side panels is fixed by bolts, which is inefficient when it is removed
In a low temperature environment, the grouting material solidifies very slowly, which also reduces the construction efficiency
Moreover, the height of the side panels along the vertical direction cannot be adjusted, which limits the use of grouted side panels

Abstract

The invention discloses a support grouting device and a grouting method thereof. The support grouting device comprises a grouting drum and a grouting pipe for causing the grouting drum to be communicated with a grouting device body. The grouting device body is erected between a box girder and a support. The grouting device body comprises peripheral side plates and a heating device, wherein the peripheral side plates are two pairs of opposite peripheral side plates, the peripheral side plates are opposite, and any peripheral side plate includes an upper layer inversely L-shaped sliding plate, alower layer L-shaped base plate and a pair of screws; and the heating device is closely attached to the outer side of a first base plate. The support grouting device has the advantages of being highin grouting efficiency and good in grouting quality, and can be widely applied to the technical field of bridge construction.

Description

technical field [0001] The invention relates to the technical field of bridge construction. More specifically, the present invention relates to a support grouting device and a grouting method. Background technique [0002] In the construction of short-line method box girder installation, it is first necessary to install the top block of the box girder pier. After the top block of the box girder pier is in place, it is necessary to consolidate and support the permanent support, temporary support and the bottom of the box girder with high-strength grouting materials. When carrying out grouting material construction, the general method is to bury reserved pipes at the inner support of box girder concrete for grouting. The key to this method is that the embedded pipes must be unobstructed. During the concrete pouring process of the box girder on the pier top, the pre-buried pipes are often blocked due to the carelessness of the workers, which makes the grouting work difficult....
