Basic embedded parts of the Bridge, Channel, and Separation Housewalted Birin Rainers are ended by the bridge construction unit, and the construction of the wave -shaped beam guardrail and the wave -shaped beam board is unanimously ended by the safety guardrail construction unit. Before the wave -shaped beam guardrail equipment, the culverts that should be based on bridges, channels, separation interchange, large -pores, and demand concrete foundations as the basis of control points based on the base or embedded component as the benchmark to measure the distance between the two sides, and use the scheduling section to adjust the column interval.

The columns should avoid the cables, pipes, and horizontal drainage pipes that cross the road. The section of the culvert with a small height and a smaller length on the top surface should be scheduled to avoid entering the pillar on the top surface of the constructor through the interval between the column. If a single orientation conflicts with the orientation of the pipeline, the foundation of cement concrete should be selected.

During construction, it should be paid attention to and shall not damage the embedded pipeline. The column equipment should be sampled according to the distance and vertical line type, and the construction of the plan drawing is strictly followed by the plan drawings.

When the wave -shaped beam board equipment, the top and the wave surface should be used to recognize the rotation between the distance between the distance or the bridge. The connection should be natural and smooth.

Due to the construction of the pavement in two phases, when the column is purchased, you should pay attention to the pillars of the pillar of the pier pores of the construction equipment in the two phases of the construction equipment.

(1) General rules

1. The equipment of the fence column shall be constructed before the soil shoulder reinforcement. It is set in the culvert constructor of bridges, channels and large spans. In the main project, the flange plate and ground foot bolt should be processed in advance.

2. Before the equipment guardrail, a detailed construction organization plan and construction preparation should be made. Commonly used things for guardrails are: pile driver, excavation, compact things, pliers, hammers and latitude and weft meters, standards, tape measures and other measuring things.

3. During the construction of the guardrail, the information of various equipment should be accurately grasped. It is especially the accurate orientation of various pipes buried in the subgrade. During the construction process, any damage to the underground equipment is not allowed.

(2) Langle columns

1. The column should be put on the sample according to the plan map, and the ranging positioning is based on bridges, channels, culverts, interchange, flat diplomatic relations, etc., and the ranging positioning is performed.

2. When the columns are put on sample, you can use the adjustment section scheduling interval, and use the distribution method to process the zero number of the interval.

3. After the columns are sampled, you should query the foundation status of each position of each column. In the case of underground communication pipelines, leakage pipes, etc., or when the depth of the burial depth of the culvert is lacking, the orientation of certain columns should be adjusted, or the basic fixing method of concrete should be selected.

(3) Pillar equipment

1. The column equipment should be consistent with the plan diagram and reconcile with the linear line.

2. The columns should be buried in the soil firmly, the depth of the plan is to be reached, and it is perpendicular to the road.

3. In general roads, the columns can be selected into the construction method. The construction should be accurately located during construction. When it is too deep, the column must not be pulled out and corrected. enter.

4. When the construction of the pillar cannot be selected, the filling height can meet the depth of the column, and the drilling construction process can be selected. Essence

5. After the column equipment is in place, its horizontal and vertical direction should form a smooth line shape.

6. Sudden variable segments and end columns of the guardrail should be equipped according to the seats of the planned rules.

7. ⑦ Due to the construction of the two -stage construction of the road surface, the pillars are reserved in the pillar in the column equipment according to the plan drawing.

(4) Polka beam equipment

1. The waveform beam is spliced with each other through the splicing bolt, and is fixed by the connection bolt on the column or beam. The stitching direction of the waveform beam should meet the plan.

2. The connection bolts and splicing bolts of the waveform beam should not be tightened prematurely so that the long round holes of the waveform beam are used in time during the device process to form a smooth line shape and avoid some unevenness.

3. The top of the waveform beam should be reconciled with the vertical curve of the journey. When the linear of the guardrail is considered to be more satisfying, it can tighten the bolt after all.
