Embodiment Construction

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0034] see figure 1 , figure 2 , image 3 , Figure 4 As shown, the embodiment of the present invention provides a construction method for small-angle (14°) inclined pile concrete pouring, including the following specific implementation aspects:

[0035] 1. Design the mix ratio of concrete according to relevant specifications and regulations, so that the concrete has high fluidity and long initial setting time. According to the construction needs, the initial setting time of concrete is designed to be more than 18 hours, and the slump loss is not more than 20mm for 2 hours. , to ensure that the inclined pile concrete has good working performance;

[0036] 2. Use the φ48*3.5mm welded pipe 6 with a length of 6m to lengthen the vibrating rod 7, so that the vibrating rod 7 has the ability to vibrate laterally, and carry ...

Description

technical field [0001] The invention relates to the technical field of bridge engineering construction, in particular to a construction method for concrete pouring of small-angle (14°) inclined piles. Background technique [0002] With the take-off of the national economy, the improvement of bridge construction and design technology, and the extensive use of new processes, new materials and new technologies, bridge design has become more creative. The design of small-angle inclined piles for roads, municipalities, railway bridges or other structures is gradually increasing. The inclined pile generally adopts the drilling and blasting excavation process, and the concrete is poured after the hole is formed. Because the angle of the inclined pile is small, the horizontal plane is long after the concrete is flattened, the top surface is triangular, and the space is narrow. A big problem. Therefore, it is necessary to study a construction method of concrete pouring with small a...
