Problems solved by technology
[0003] The purpose of the present invention is to provide a construction method for pile point positioning at night, so as to solve the problem that when CFG pile foundation construction is carried out at night, the pile location is easy to deviate, which leads to the misplacement of CFG pile foundation installation, and it is difficult for the staff to quickly find the pile location The problem

Embodiment Construction
[0017] see figure 1 Shown, night pile point location setting method of the present invention comprises the following steps:
[0018] a. Select several laser lamps 1, the number of laser lamps 1 is determined according to the number of CFG piles 2 to be laid. In order to ensure the safety of the construction workers, the light beam emitted by the selected laser light 1 is safe to the human body and will not cause harm to the human body. At the same time, the laser light must be operated safely, and it is strictly forbidden to irradiate the eyes or prevent the eyes from being irradiated. Since red light and green light intersect to produce yellow light, several laser lamps 1 selected in the present invention emit red light, and several emit green light.
[0019] b. On the construction site, determine the location of the layout area of the CFG pile foundation 2 according to the construction design drawings.
[0020] c. According to the regional position of the CFG pile founda...

The invention provides a nighttime positioning construction method of pile points. The method comprises the following steps: a, selecting a plurality of laser lamps; b, determining the position of an arrangement area of a CFG pile foundation based on the construction design drawings; c, correspondingly arranging laser lamp mounting points at the transverse side edge and the longitudinal side edge of the periphery of the CFG pile foundation arraignment area in a construction field based on the area position, marked in the construction design drawings, of the CFG pile foundation in the field; d, mounting each laser lamp at the position, close to the ground, of each laser lamp mounting point at the transverse side edge; e, mounting each laser lamp at each laser lamp mounting point at the longitudinal side edge; f, debugging the laser lamps; and g, vertically drilling a hole in an intersection point of each laser beam through a long spiral drill; and pouring concrete in the drilled holes. With the adoption of the method, the pile points are hard to stagger and deviate during construction process; in addition, the pile points are easily observed by construction people at night with poor light, and thus the construction efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of pile point setting, in particular to a construction method for pile point positioning at night. Background technique [0002] CFG pile foundation is a cement, fly ash and aggregate mixed material pile, which is used in foundation treatment and is a component of artificial composite foundation. Because of its low price, it is often used to deal with weak foundations to build low-rise and multi-storey houses. Since the distance between two adjacent CFG pile foundations is relatively close, in order to ensure the stability of the stratum, the CFG pile foundation is often laid by jumping drilling construction during construction. However, using this method will easily damage the skipped pile points of the unlaid CFG pile foundation, causing misalignment and deviation of the pile points, which will make it difficult to lay the CFG pile foundation to the original set position. In actual work, in order to spee...
