Example Embodiment

[0024] As the present invention figure 1 The main purpose of the first embodiment shown is to introduce the construction method of pouring small-diameter pile-hole concrete in bags. In the first step of the first embodiment of the present invention, the pile position is determined according to the design and construction drawing, and the pile hole (1) is completed by digging or drilling construction, such as figure 1 Shown. Thus, the first step of the first embodiment of the present invention is completed, and the second step is entered. Due to the small diameter of the pile hole (1), it is difficult to use the conduit method for concrete pouring, and the small-diameter pile hole concrete bag pouring construction method of the present invention can be used for concrete pouring construction. In this step, load the uncured concrete (2) into figure 1 In the bag (3) shown, the bag (3) can be made of dense wire mesh. The cross-sectional size of the bag (3) should be smaller than the...

Abstract

The invention relates to a construction method for concrete bagged pouring in a small-diameter pile hole in the field of pile foundation engineering. The construction method comprises the following steps of: a) determining a pile position and finishing the construction of the pile hole (1); b) filling immature concrete (2) into a bag (3) of which the section is smaller than that of the pile hole (1); c) placing the immature concrete (2) bagged into the bag (3) in the step b) into the pile hole (1) together with the bag (3); d) determining whether to repeat the step b) and the step c) according to the amount of the concrete required to be poured, if the one-time pouring quantity satisfies the requirements, the step is not required; and e) compactly filling the immature concrete (2) poured into the pile hole (1) into the pile hole (1). The invention also provides a prefabricated extrusion and expansion pile construction method for concrete bagged pouring by utilizing a hollow part of a hollow prefabricated pile (6) taken as the pile hole (1). The invention has the beneficial effects that the pouring construction of the cast-in-place concrete in the small-diameter pile hole (1) can be smoothly finished; the construction method is simple; and the quality is reliable.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to the field of pile foundation engineering. Background technique [0002] Pile foundation engineering is one of the important components in the field of civil engineering. At present, the commonly used engineering pile forms mainly include prefabricated piles and cast-in-situ piles. Prefabricated piles include steel pipe piles, prefabricated square piles, PHC pipe piles, prestressed hollow Square piles and other forms, which are characterized by prefabricating engineering piles and placing them into the soil, and using the joint action of piles and soil to provide compression, pullout, bending or horizontal bearing capacity. For the underwater pouring of concrete in the pile body, such as bored piles, the diameter of the borehole is required to be large enough, and the pouring method is used for pouring, but when the pile diameter is small, such as the diameter of the pile hole is ...
