It's simple. There is nothing difficult about it.

What is the specific content of the small bridge construction organization design plan, the following Zhongda Consulting will answer for you.

Project Overview. The central station of the small bridge is K2+, the bridge is a 1-13m prestressed concrete hollow slab bridge, the full length of the bridge, the bridge is located in a straight section, the vertical curve R 20000m, T 60mThe bridge is wide, and the upper balance structure is a C30 prestressed concrete hollow slab girder, and the whole bridge has a total of 10 girders.

The substructure is a U-shaped abutment with an enlarged foundation.

Preparation for construction. 1. The entry of the construction team.

The construction team has now entered the site and rented a local house as a temporary station, and after entering the site, it has solved the problems of communication, electricity and water, and set up the necessary safety signs. Organize technical personnel to carefully study and verify the construction design drawings, and be familiar with the technical specifications and supervision procedures of the contract text.

2. The setting of the mixing plant.

The mixing yard is planned to be set on the K2+880 K2+900 filled embankment, and the concrete of the bridge is mixed in a centralized manner. After the bridge construction team entered the site, the site was leveled and hardened. From the provincial highway S324 line to the construction site, a construction road was built to ensure smooth transportation during the construction period, and the installed mixing equipment was debugged and calibrated.

See the annex for the layout of the bridge site construction plane rubber barrage).

3. Measurement lofting.

Before expanding the excavation of the foundation pit, measure and loft out the excavation side pile, drive the wooden pile, and locate the center position on the wooden pile with a small iron nail. Then report to the supervising engineer for inspection, and start construction after passing the review.

4. Test. a. The laboratory has tested raw materials such as cement, steel bar, gravel, river sand, etc., and the test results meet the requirements of the specification. The C20 and C25 concrete mix ratio has been supervised and approved, and the C30 concrete is being tested.

b. Conduct sampling inspection of raw materials used for the project. Strictly control the entry of unqualified raw materials into the site. Strictly inspect the materials of important structural parts such as steel and cement to see if they are accompanied by quality inspection marks and factory certificates; And according to the requirements of the corresponding specifications sent to the laboratory of the supervision office for inspection.

c. For the purchased finished materials, there must be a certificate of conformity, and Liang Shen sent a qualified department to pass the inspection before entering the construction site.

5. Material preparation and planning.

a. Sand, pebbles.

The sand is purchased from the moat head sand yard, and the crushed stone is purchased from the suburban material yard. It is transported to the construction site by truck.

b. Cement and steel.

The cement is made of Yizhang County Baishidu Huiliang Qianglong brand cement and Chenwang brand cement; The steel is made of Lianyuan Steel products. It is transported to the construction site by road transport. Materials must be sorted and stacked after entering the site. Finished products and raw materials are marked.

c. After all materials enter the site, they will be self-inspected and qualified, and then reported to the supervision engineer for random inspection, and can only be used after being approved by the supervision engineer.

6. Construction period. The start date is December 28, and the completion date is July 11, a total of 225 days.
