Problems solved by technology

The traditional manual removal of the hole-forming pile heads not only wastes a lot of concrete, but at the moment when labor wages are rising day by day, the labor cost is particularly prominent, and the pollution of the environment due to the large amount of broken waste concrete and other construction waste cannot be underestimated.

Embodiment Construction

[0033] Refer to attached picture.

[0034] Exemption of the present invention removes pile head construction method and comprises the following steps:

[0035] Step 1, excavate the earthwork to the level of the bottom of the cap.

[0036] Before the hole is formed, the soil is excavated to the elevation of the bottom of the cap. In order to ensure the quality of the hole, avoid excessive hole drilling and avoid the disturbance of the pile body by the excavation after the pile is poured, the pile should be excavated before the hole is formed. The earthwork in the area will be excavated to the designed cap bottom elevation, and at the same time, a working surface will be provided for the inverted electric suspension rod in-situ stirring reinforcement method without chiseling pile heads.

[0037] Step 2, determine the concrete filling height of the pile body.

[0038] 2.1 Calculation of the rest elevation of the pile body concrete pouring: after the hole is formed, the pile bod...

Abstract

The invention provides a chiseling-free pile head construction method. The chiseling-free pile head construction method includes the steps that earthwork is excavated to the bottom elevation of a bearing platform; the pile body concrete pouring height is determined; a mud pile head reinforcement material is prepared; an inverted type electric suspension rod stirring machine is installed; laitance is removed; the inverted type electric suspension rod stirring machine stirs the in-situ pile head reinforcement material; curing is conducted; and drilled core sampling pressure test acceptance inspection is conducted. Compared with the traditional construction process for manually chiseling pore-forming pouring pile heads, the construction procedure is greatly simplified, the construction cost is reduced, the requirement for the construction technology of constructors is not high, the construction safety is good, and the construction period is shortened.

Description

technical field [0001] The invention is applicable to the construction of hole-forming cast-in-place piles of various hole-forming machines such as manual digging and drilling. Background technique [0002] With the vigorous development of urbanization, high-rise buildings that symbolize the prosperity of the city can be seen everywhere, and the structural design of pile foundations supporting high-rise buildings is widely used. The traditional manual chiseling of the pile heads of cast-in-place piles not only wastes a lot of concrete, but the labor cost is particularly prominent at the moment when labor wages are rising day by day, and the pollution of the environment caused by a large amount of broken waste concrete and other construction waste cannot be underestimated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method without chiseling and removing pile heads, which can simplify the process...
