Problems solved by technology

From the perspective of engineering practice, due to the influence of construction technology, the waterproof effect of construction joints is often unsatisfactory, and it is impossible to prevent the water flow in the culvert from seeping into the subgrade, resulting in uneven settlement of the filled subgrade, and even af

Example Embodiment

[0027] Examples of the present invention:

[0028] First, use a cutting machine to cut both sides of the original culvert settlement joint, then use an electric impact drill to pick out the groove, and then artificially refine it into groove 6; groove 6 is 5cm wide and 8cm deep.

[0029] Second, use an electric drill to drill a hole in the settlement joint of the original culvert, install the grouting pipe 1 and grouting; the interval of the grouting pipe 1 is 25cm, the hole depth is 10cm, and the hole diameter is 15mm; the high-pressure grouting pump is used for grouting water-soluble polyurethane The mixture of plugging agent and acetone is poured from the bottom of the culvert to the top of the culvert at one time. The grouting is stopped after the grouting pressure reaches 0.5MPa. After the grouting solution has solidified for 1 to 2 days, the grouting nails are removed and the leakage is stopped. Wang blocked the grouting hole.

[0030] Third, clean the gaps and grooves 6, inst...

Abstract

The invention discloses a reinforced concrete culvert settlement joint water seepage treatment method and a repair structure thereof. The two sides of a settlement joint are cut to form a groove (6);the settlement joint is drilled, a grouting pipe (1) is mounted, and grouting is conducted; a water conduit (2) is laid along the portion, inside the groove (6), of the settlement joint; the water conduit (2) is provided with a drainage hole (5) and a drainage pipe; the groove (6) is packed with a packing layer (3); and a water-proof layer (4) is arranged on the surface of the groove (6). By meansof the reinforced concrete culvert settlement joint water seepage treatment method and the repair structure thereof, the water seepage problem of the culvert settlement joint is effectively solved; the anti-seepage effect is obvious; and operation is easy to conduct, and economic efficiency and practicability are achieved.

Description

Technical field [0001] The invention relates to a treatment method for defects of engineering quality, in particular to a treatment method for the settlement joint seepage of reinforced concrete culverts. Background technique [0002] When highways and railways cross gullies and remove water flow from the side ditch on the inner side of the roadbed, culverts are often built to meet the safety and continuity of the roadbed. Reinforced concrete slab culverts are widely used in engineering because they have low requirements for the filling height of the top of the cave, and low requirements for foundation stress, and are convenient for construction. [0003] In order to prevent uneven settlement, culverts are generally constructed in sections, with settlement joints between the sections, and the settlement joints are filled with asphalt batt or other impervious materials. From the perspective of engineering practice, due to the influence of construction technology, the waterproof eff...
