Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] Such as Figure 2-14 As shown, an anti-overturning assembled pile structure includes a cast-in-place cement concrete pile 1 poured in the pile hole, and the top of the cast-in-place cement concrete pile 1 is provided with a locking assembly for anti-overturning. The cast-in-place cement concrete pile 1 is located at the lower part of the entire pile structure, and its function is to bear the upper load and transfer the load to the soil foundation. The cement concrete pile 1 is made in the form of cast-in-place...

Abstract

The invention discloses an anti-overturning fabricated pile structure and a construction method thereof, and relate to the field of buildings. The structure comprise a locking assembly, the locking assembly comprises a variable cross-section joint and an anti-overturning plate, the variable cross-section joint is of a circular truncated cone structure with a upper part narrower than a lower part,a hollow part allowing the variable cross-section joint to pass through and forming a locking state with the variable cross-section joint is arranged in the middle of the anti-overturning plate, and in a mounting state, the outer surface inclined plane of the variable cross-section joint is tightly connected with the inner surface inclined plane of the hollow part of the anti-overturning plate toform self-locking. The construction method comprises the steps of variable cross-section joint prefabrication, steel sleeve installation, concrete pouring of the variable cross-section joint, anti-overturning plate prefabrication, pile hole excavation, cement concrete pouring, steel bar pre-burying, variable cross-section joint installation, cement mortar pouring, anti-overturning plate installation and soil covering. According to the structure and the method, a cement concrete pile is well connected with the anti-overturning structure by designing a steel sleeve, pre-burying steel bars and pouring cement mortar, so that the situation that the anti-overturning capacity is improved by means of the mode of increasing the diameter and the length of the pile is avoided.

Description

technical field [0001] The invention relates to the field of construction, in particular to an anti-overturning assembled pile structure and a construction method thereof. Background technique [0002] The existing technology mainly focuses on increasing the pile diameter and pile length to improve the anti-overturning ability of piles, as shown in the accompanying drawings figure 1 However, improving the anti-overturning ability of piles by increasing pile diameter and pile length will lead to waste of materials and increase construction costs, especially for projects such as factory buildings and portal frames that have anti-overturning requirements, and these projects are less investment. and some of them may be only temporary projects, which will be dismantled after the use is completed, so it is not economical to improve the anti-overturning ability of piles by increasing the pile diameter and pile length in the existing technology, which is also one of the shortcomings...
