Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] Such as figure 1 As shown, a bridge grouting pipe includes a pre-embedded pipe 1 reserved inside the wall for concrete pouring. The inner movable sleeve of the pre-embedded pipe 1 is equipped with an inner liner 2, and one end of the inner liner 2 is located outside the wall. The limited protrusion is formed, and the outer end diameter of the limited protrusion is larger than the inner cavity diameter of the embedded pipe 1, and the end threaded sleeve ...

Abstract

The invention relates to the technical field of traffic bridge construction, and discloses a bridge grouting tube. The bridge grouting tube comprises a pre-embedded tube which is concrete-cast and reserved inside a wall body, wherein a liner tube is movably arranged inside the pre-embedded tube in a sleeving mode; and one end, outside a wall body, of the liner tube is equipped with a limiting bump. According to the bridge grouting tube disclosed by the invention, a grouting head is in blocking connection with the pre-embedded tube, and a grouting hole is directly formed in the end part of thegrouting head, so that during grouting, slurry is filled up outwards from the most distant position of a bridge gap; when slurry flows to the end surface of a bridge along the gap, the gap can be judged to be completely filled up with the slurry, so that a condition that people wrongly thinks that the gap is filled up as slurry, injected from the grouting hole in the front end of the grouting tube, flows out from the gap of the bridge in advance is avoided; and a wrong region for grouting is stopped, so that grouting quality is improved.

Description

technical field [0001] The invention relates to the technical field of traffic bridge construction, in particular to a bridge grouting pipe. Background technique [0002] At present, when the bridge is poured, the grouting pipe (a long pipe with through holes on the pipe wall and the pipe end) is often embedded inside it. The function of the pre-embedded grouting pipe is to use the grouting pipe as the skeleton of the bridge on the one hand. , improve the overall compression resistance of the bridge, on the other hand, after the bridge concrete is poured, the grout can be poured into the grouting pipe through the grouting pump, and the grout will flow to the bridge through the grouting hole opened on the grouting pipe under the action of pressure. Fill the gap between the wall and the pipe due to air bubbles in the concrete to improve the compactness of concrete pouring, and then fill the grouting pipe with grout to improve the pouring quality of the bridge.
