Heightened construction method for active service stone building bank protecting wall

Abstract

The invention relates to a heightened construction method for an active service stone building bank protecting wall. The heightened construction method includes the following steps that (1) an original bank protecting slope is cleaned and repaired; (2) anchor rod construction is carried out; (3) lattice girder construction is carried out; (4) foam concrete construction is carried out; (5) pavement construction is carried out; (6) newly-increased protection bank construction is carried out; and (7) concrete curing is carried out. A structure related in the heightened construction method comprises angle iron arranged at the top of an original protection bank according to a certain distance, the angle iron and embedded steel bars at the top of the original protection bank are connected in a welded manner, and a foam concrete sea side formwork and a newly-increased protection bank side mold are connected with the angle iron in a fastened manner through screws; prefabricated slabs are evenly inserted and piled on the foam concrete bank side, a foam concrete bank side formwork is arranged to be in a separated manner and is connected with the prefabricated slabs in a fastened manner through box iron, the screws and nuts; and newly-increased protection bank framework reinforcing steel bars and original protection bank embedded steel bars are connected through a direct threaded sleeve. The heightened construction method for the active service stone building bank protecting wall has the beneficial effects of being reliable in structure, convenient to construct, short in time limit for a project, environment-friendly and good in concrete appearance quality.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and relates to a construction method for revetment walls, in particular to a construction method for heightening revetment walls in active service. technical background [0002] A large number of built revetments have low design standards, and have been continuously eroded and scoured by seawater for a long time, and have gradually lost their function of resisting storm tides, waves, and currents, and protecting the inner and outer banks of the port. In the face of such a large number of revetments in active service, it is unscientific and wasteful of people and money to tear them down and rebuild them all. Therefore, it is necessary to heighten and strengthen the revetment wall in active service in order to meet the structural safety and practical requirements. This kind of revetment wall heightening and strengthening projects in active service have shown an increasing trend year by ...

AI Technical Summary

Problems solved by technology

[0003] At present, the treatment of active revetment walls mainly includes in-situ reconstruction method, cast-in-situ pile reinforcement method, micro-pile reinforcement method, etc. When the in-situ reconstruction method is adopted, the original diseased retaining wall is removed, and the revetment wall is rebuilt according to the new norms. Large-scale excavation is required, the excavation depth is large, the construction period is long and the cost is high; the cast-in-place pile reinforcement method, that is, the perforated pile is directly used for reinforcement at the bank side, and the disturbance to the active revetment wall during the punching operation Larger, there are greater safety hazards in construction; the micro-pile reinforcement method is relatively new, and the construction is convenient, but the cost performance is poor
