Problems solved by technology

However, due to the unequal service life of the waterproof membrane, and the maintenance cost of the arch bridge in the later stage is relatively high, help how to adopt special construction methods and process improvements in the construction, so as to meet the requirements of the later stage of the arch bridge to prevent water from seeping into the belly arch, forming At the same time, because there is a concave groove between the abdominal arches, it is easy to accumulate water and form a corrosion-prone area

Embodiment 1

[0026] A construction method for preventing corrosion of an arch bridge, comprising the following construction steps:

[0027] S1, construct the pile foundation of the arch bridge according to the drawings;

[0028] S2, then the pile cap, set up a full house of scaffolding;

[0029] S3, carry out the construction of main arch ring 1 according to the drawings;

[0030] S4. After the concrete strength of the main arch ring 1 meets the design requirements, the concrete construction of the pier cap 5 is carried out after the steel bars of the pier cap 5 are bound;

[0031] S5, carry out the construction of pier column 6 according to drawing;

[0032] S6, after the construction of the pier column 6, set up a support on the main arch ring 1, and carry out the construction of the abdominal arch ring 2;

[0033] S7. After the construction of the belly arch ring 2 is completed, a concrete layer with the same strength as the main body of the bridge is poured between the two belly arc...

Abstract

The invention discloses a construction method for preventing corrosion of an arch bridge; the method comprises the steps that a concrete layer with the same strength as a bridge body is poured betweentwo web arch rings, and transverse slopes are arranged on two sides of the cross section of the concrete layer; sheets with holes are paved on the upper surfaces of the web arch rings and a main archring according to a plurality of longitudinal sections, and a hot melt adhesive is injected into the holes of the sheets; after demodulation is finished, backfill materials are added above the sheetsaccording to the drawing requirements until the bottom elevation of the pavement is reached; finally, the pavement construction is carried out. According to the method, water seepage between the webarches can be effectively removed, and the effect of corroding concrete on the upper surface layers of the web arches can be effectively avoided; by using the method, the operability is high, field manufacturing is simple, economy and applicability effects are achieved, the later maintenance cost can be effectively reduced, and potential quality hazards are effectively eradicated.

Description

technical field [0001] The invention belongs to the field of civil engineering building construction, and in particular relates to a construction method for anticorrosion of arch bridge construction. Background technique [0002] Arch bridges are mostly used in urban and landscape design in my country, and are also used when crossing canyons and mountain rafting. The upward arch bridge adopts the main arch ring, upper column and abdominal arch structure, and the water flow under the bridge is diverted by using the main abdominal arch structure. The force on the bridge is uniform, and the arch bridge is mostly constructed with inclined piles and vertical piles to break down the lateral pressure of the arch ring. [0003] After the construction of the belly arch of the upward arch bridge, it is backfilled with limestone gravel until the bottom elevation of the road surface is reached, and then the road surface project is constructed, that is, all the main constructions are comp...
