example I

[0031] Engineering example I: According to geological conditions, design requirements, equipment status, screw pile inventory and production speed, flexible selection can be carried out for pile connection operations.

[0032] Using Φ400 spiral prefabricated piles, the geological conditions are as follows: 0.8~1.8M is plain fill (medium density), 1.8~2.6M is loamy soil (medium density), 2.6~5.1M is clay (hard plastic), 5.1~5.8M is medium sand (medium density), 5.8 ~ 12M is garden gravel (medium density). According to the geological report, the length of the selected pile is 7M core hole alignment spiral prefabricated pile, and the drill tip is open type. When drilling to 2m during operation, it is difficult to advance the footage, and there is a phenomenon of suffocation in the further advance. At this time, the pressure water of the injection belt is greatly improved, and the advance is smoother. The soil is obviously moist and naturally falls off from the screw pitch. When t...

example II

[0034] The plane size of the foundation pit is 110M×60M. The original design uses Φ600 superfluid helical bored piles, with a center distance of 1.2M, a total of 278 piles, a pile length of 15M, and a top-loading beam (handle beam) of 400MM×600MM. The construction cost is more than 1 million yuan, the consumption of steel is 90 tons, and the cement is 600 tons. Instead, use Φ500 type core holes and spiral prefabricated piles at the same head. The length of the pile is 15M, and the number of piles is still 278. The handle beam uses section steel to fasten the pile core section steel. The total cost is 550,000 yuan, the steel consumption is 30 tons, and the cement consumption is 230 tons. Synthetic fiber consumption is 410 kg. Compared with saving 45% of funds, 66% of steel products and 62% of cement.

Abstract

The present invention belongs to the field of building engineering pile construction technology. The building engineering pile constructing process includes the following steps: 1. making prefabricated spiral concrete pile with middle core hole; 2. setting the core pulling tool inside the core hole; 3. fixing the pile cap to the core pulling tool and the upper end of the prefabricated spiral concrete pile; 4. hoisting and driving the pile cap to drill; and 5. grouting the outside of the prefabricated spiral concrete pile through the core hole. The apparatus for the construction includes prefabricated spiral concrete pile with middle core hole, core pulling tool inside the core hole and pile cap fixed to the core pulling tool and the upper end of the prefabricated spiral concrete pile. The present invention can suit for different soil qualities and has low engineering cost, simple construction and high reliability.

Description

technical field [0001] The invention belongs to the field of civil engineering pile construction, and in particular relates to a method for manufacturing a construction engineering pile and an adopted device. Background technique [0002] In foreign civil engineering, the spiral R.C. pile system is placed into the soil by applying torque and rotating. In this pile method, the prefabricated screw pile is screwed into the ground by a strong torque. Due to the construction method, the pile is made of high-strength cement reinforcement, which is complicated. The virtual soil and the pile body are also agitated soil, which are lower than the strength of the undisturbed soil. This kind of construction method has not been found in China. [0003] Hammer vibration method is rarely used in domestic cities subject to pollution restrictions. Static pressure pile equipment is huge and the construction cost is high. Pipe piles are expensive to meet the static pressure of huge equipmen...
