What are the contents of the bridge appearance survey?

1.Bridge deck pavement: whether there are potholes, cracks, ruts, loose, uneven, bridgehead jumping and other phenomena.

2.Anti-collision guardrail: whether there is looseness, damage, rust and deformation, etc.

3.Expansion joints: whether there is damage, falling off, silting, packing bumps, jumping, water leakage, etc.

4.Drainage facilities: whether the cross slope and longitudinal slope of the bridge deck are suitable and whether there is stagnant water; Whether the drain pipe is damaged or blocked, and whether the discharge capacity is suitable for needs; Whether the waterproof layer is working normally, whether there is water seepage, etc.

5.Upper bridge structure: whether there is cracking at the fulcrum of the main beam and the middle of the span, and what is the maximum crack value; Whether there are cavities, honeycombs, hemp surfaces, peeling off, and exposed ribs on the surface of the beam; There is no local water seepage.

6.Bearing: whether the displacement is normal, whether there is voiding and deformation.

7.Bridge piers: whether the pier body is cracked, local external drum, surface peeling, cavities, exposed ribs, etc.; Whether there is deformation, tilting, settlement, erosion, slippage, etc.

8.Abutment: whether the platform body is cracked or damaged; Whether there are cracks in the back of the table filling, extrusion, etc.

9.Cone slope: whether there is damage, subsidence, cracking, erosion, slippage, etc.

10.Conditioning structure: whether it is functioning normally, whether there is damage, water damage, etc.

Methods and steps of visual inspection:

1. Collect the design and completion data of the bridge, and fully grasp the relevant situation of the bridge.

2. Use detection and measurement tools to visually inspect the technical condition of the bridge, and record the inspection results into the table. The specific survey methodology is as follows:

1) Measurement. Leather tape measure, steel tape measure of different lengths, with vertical ball and level, etc., are used to measure the size and span.

2) Bridge deck flatness. A three-meter ruler was used to measure the depth of the deck grooves on the main lanes on both sides of the bridge.

3) The investigation of pier erosion, bridge head subsidence, bridge deck drainage, anti-collision guardrails, bearings, etc., mainly relies on field observation and analysis.

4) Take pictures of the diseased parts of the bridge.

The appearance mainly depends on the quality, color and integrity of the concrete appearance of the box girder.

In addition, the overall alignment of the bridge is smooth.

Summary. Hello, to conduct a bridge design data survey to do a data survey, the main thing is to provide evidence, for example, we have to do some investigations, that is, to provide arguments for your arguments, so as to make your article more convincing.

The main contents of the investigation are;

1.Determine the span of the beam, estimate the cross-sectional size preliminarily, and establish a calculation diagram.

2.Determine the strength grade of concrete and rebar. Determine the seismic rating.

3.Calculation of various loads, e.g. dead load, live load, etc.

4.The internal forces are analyzed, the bending moment diagram and the shear force diagram are drawn, and the support reaction force is obtained.

5.The cross-section design is equipped with longitudinal stressed steel bars, stirrups, etc., and structural steel bars are selected. At the same time, attention should be paid to meeting the construction requirements.

6.If necessary, check whether the deflection and crack width meet the requirements.

7.Draw structural construction drawings.
