Embodiment 1

[0053] The embodiment of the present application discloses an efficient multi-equipment construction method for an automated pile body non-squeezing soil type carrier pile. refer to figure 1 and figure 2 , the multi-equipment efficient construction method of the automatic pile body non-squeezing soil type carrier pile includes the following steps:

[0054] S1. When the equipment enters the site, prepare cranes, vibratory hammers, hydraulic clamps, hydraulic hoists 1, rammers 2, steel casings 3 and packing conveying devices at the construction site. In the construction site of large quantities of compressive carrier piles, the above construction equipment Prepare a plurality of them, wind the suspension rope 4 on the hydraulic winch 1, install the rammer 2 on the hook at the end of the suspension rope 4 for tamping the packing, install the hydraulic clamp on the end of the steel casing 3 and The vibratory hammer is installed on the crane for sinking the steel casing 3 , and ...

Embodiment 2

[0074] The embodiment of the present application discloses an efficient multi-equipment construction method for an automated pile body non-squeezing type carrier pile. 2's vertical height or the altitude above sea level is marked, and during actual calibration, a GPS instrument connected with computer information is installed on the upper end of the rammer 2. The method of marking the zero point is: lower the rammer 2 to the bottom of the pit before ramming, calibrate the vertical height or altitude of the rammer 2 through the GPS instrument, and set the vertical height or altitude as the zero point of the rammer 2 .

[0075] The method for measuring the sinking depth is: after lowering the rammer 2 during tamping, measure and calculate the vertical height or altitude of the rammer 2 at this time through the GPS instrument, and subtract it from the vertical height or altitude of the rammer 2 at the zero point The calculated vertical height or altitude can be used to obtain th...

Embodiment 3

[0080] The embodiment of the present application discloses an efficient multi-equipment construction method for an automated pile body non-squeezing soil-type carrier pile. Cylinder 3, specifically, since the steel casing 3 generally has a wall thickness of 15-30 mm, a small static pile machine is used to statically press the steel casing 3 to the design elevation. When the static pressure method is selected to sink the steel casing 3, the vibration of the surrounding soil is less affected, which effectively ensures the stability among multiple compressive carrier piles.

Abstract

This application discloses an efficient multi-equipment construction method for an automated pile body non-squeezing type carrier pile, which includes the following steps: S1. Lowering the hammer to the bottom of the pit is defined as the zero point of the rammer lowering. When ramming, the sinking depth of the rammer can be calculated by taking the difference between the position of the rammer at the zero point and the position of the rammer after ramming; S5. Automatic packing rammer Strike, deliver the set amount of filler to the bottom of the pit, lower the hammer and detect the sinking depth; if the sinking depth is between -5cm~5cm, automatically deliver the set amount of filler to the bottom of the pit and lower the hammer; if the sinking If the depth is less than ‑5cm, automatically control the tamper for several times; if the sinking depth is greater than 5cm, automatically control the conveying device to deliver more than the set amount of filler to the bottom of the pit; S6. Three-stroke penetration detection; S7. Concrete piles Body construction; S8. Extubation. The application has the ability to automatically measure and calculate the sinking depth of the rammer and automatically control the filling or continuous ramming operation, which effectively improves the construction quality and efficiency.

Description

technical field [0001] The invention relates to the field of carrier pile construction technology, in particular to an automatic pile body non-squeezing soil type carrier pile multi-equipment efficient construction method. Background technique [0002] The carrier pile is a type of pile composed of four parts: pile concrete, compacted filling material, compacted soil, and impacted soil, which can be equivalent to expanding the force of the foundation. There are clear advantages when using piles. The construction steps of the carrier pile are mainly divided into hole forming, carrier construction and pile body construction. There are many construction methods for carrier pile hole forming, such as column hammer impact, vibrating pipe sinking, rotary excavation or hydraulic hammer, down-the-hole hammer and other hole forming techniques. The cement content in the cement-sand mixture is less at first and then more, and it is repeatedly tamped with a column hammer. After reachi...
