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.

Description

technical field

[0001] The invention relates to the technical field of bridges, and more specifically, relates to a construction method for piers of an anti-overturning simple access bridge and a construction method for an anti-overturning simple access bridge. Background technique

[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 easi...

Embodiment Construction

[0041] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0042] The present invention provides a construction method for the pier 1 of a simple anti-overturning portable bridge. The simple portable bridge can be, for example, a steel temporary bridge. The construction method for the pier 1 of the simple anti-overturning portable bridge includes multiple steps. For details, please refer to step 1 to step 2.

[0043] Step 1: Excavating a foundation pit, and processing the foundation 11 in the foundation pit;

[0044] In this step, steps S01)-S04) are also included:

[0045] S011), excavating the foundation pit;

[0046] Specifically, a foundation pit (not shown in the figure) is excavated at the place where the anti-overturn...
