Key Points Of Construction Of Buried stones Concrete Foundation Of River Embankment !

1. The structural form of buried stone concrete foundation of river embankment

The buried stone concrete foundation of river embankment is a common structural form of river embankment engineering, which is mainly composed of C15 stone concrete. Among them, the height of the schist concrete foundation is 1.5 meters, while the width is between 2.47 meters and 4.48 meters, the specific width value can refer to the construction profile. In the construction process, it is necessary to follow certain construction procedures and technological processes !

2. The construction procedures and technological flow of buried stone concrete foundation of river embankment

(1). Measurement lofting:
Before construction, it is necessary to measure lofting to determine the location and size of the foundation.

(2). Mold building: According to the lofting results, the template is built.

(3). Concrete pouring: Pour C15 concrete in the formwork.

(4). Stone in: before the concrete is completely set, the stone is put into the concrete.

(5). Vibration: After the stone is put in, vibration is carried out to make the concrete and stone fully combined.

(6). Leveling: After the vibration is completed, leveling is carried out to make the surface of the foundation smooth.

(7). Maintenance: After the foundation is completed, maintenance is carried out to ensure the strength and stability of concrete.

3. The technical indicators and acceptance requirements that need to be paid attention to in the construction of buried stone concrete foundation of river embankmenT !

(1). The spacing between the stone and the template should not be less than 15 cm, and it needs to be vibrated tightly.

(2). The amount of stone should not exceed 15% of the base volume, and the strength grade of stone should not be less than MU40.

(3). Strictly control the width, thickness, strength of the foundation and the proportion of the volume of the stone and other technical indicators.

(4). After the acceptance of the foundation, it is necessary to remove debris, soil and loose rocks on the rock foundation, and then pour concrete after the treatment is completed !

(5). Before pouring the bedrock surface, lay a layer of cement mortar 2-3 cm thick before pouring the first layer of concrete. The water-cement ratio of mortar should be adapted to the pouring strength of concrete to ensure a good combination of concrete and base rock !

(6). After the completion of pouring, it is necessary to carry out inspection, and only after passing can the construction of the next process be carried out !

In general, the embankment buried stone concrete foundation is an important structural form, and its construction needs to follow strict procedures and technological requirements to ensure the quality and safety of the project. In the construction process, it is necessary to pay attention to technical indicators and acceptance requirements to ensure the stability and strength of the Foundation !
