Anti-overturning simple temporary bridge pier construction method and anti-overturning simple temporary bridge construction method

Abstract

The invention relates to an anti-overturning simple temporary bridge pier construction method which comprises the following steps: 1, excavating a foundation pit, and treating the foundation in the foundation pit; 2, sequentially superposing and fixing a plurality of gabion units on the foundation from bottom to top to form a bridge pier structure. According to the construction method, the construction cost of the temporary bridge is low; compared with a reinforced concrete bridge pier, the method has the advantages that formwork erecting and concrete pouring processes can be omitted, the processes are effectively optimized, and the cost is reduced; the process is simple and convenient, the operation is simple, so large-scale construction can be rapidly and efficiently carried out, and thetime can be effectively saved; by using the method, the safety coefficient is effectively improved, and the problem that a traditional temporary steel temporary bridge pier is poor in anti-overturning capacity is effectively solved; the method is ecologically friendly, and later dismounting is convenient. In addition, the invention further relates to an anti-overturning simple temporary bridge construction method.

Problems solved by technology

[0002] During the construction of highway bridges and culverts, in order to ensure that construction personnel, materials, and machinery enter the site, the temporary access bridge must first be opened. The bridge piers of the temporary steel access bridge are traditionally made of reinforced concrete cast-in-situ piers or prefabricated piers, which requires high initial investment costs and long time. High difficulty

And the bridge pier has the effect of resisting the active earth pressure of the backfill soil on the abutment back, especially when the vehicle passes through the abutment back to generate horizontal braking force, this active earth pressure effect is strengthened, which can easily cause the pier to slip and overturn, and induce safety accidents, especially in the This destructive effect is especially severe in areas with complex geology or shallow groundwater levels

[0003] Therefore, in the actual construction, it is necessary to calculate the anti-overturning moment of the bridge pier. The calculation process is complicated and difficult. For the sake of safety, the bridge pier often needs to go deeper into the riverbed, which makes the construction more difficult and the amount of work increases.
