Problems solved by technology

[0003] The purpose of the present invention is to provide a vibrating tube-immersed pneumatic pile machine, to solve the problems of poor material discharge and uneven pile body during the tube-immersion operation of saline soil and other soft ground with high water level; and to solve the problem that the traditional pile machine cannot realize One-time feeding into piles, groundwater is not easy to discharge, construction speed is slow, and foundation treatment costs remain high

Embodiment 1

[0031] Example 1 see Figure 2-4 , the above-mentioned air supply steel pipe is an attached air supply steel pipe 12 close to the inner wall of the pile pipe, and its air inlet 11 is located on the pile pipe wall opposite to the feed inlet below the one-way valve. The pile tube lower end discharge port of the above-mentioned vibrating tube sinking wind pile machine is connected with a built-in pile shoe 51, which is built in the pile tube by 2 or more steel pile shoe plates, and is closed when the tube is immersed. The above-mentioned one-way valve and the built-in spud can are two semicircular blades hinged on the hinge axis crossing the pipe wall, and a return spring is connected between the semicircular blades and the central shaft. The one-way valve is opened when feeding, and closed when pneumatically feeding.

[0032] see image 3 , the lower end discharge port of the pile tube of the above-mentioned vibrating tube sinking wind pile machine is connected with a movable ...

Embodiment 2

[0034] Example 2 see Figure 5 , the above-mentioned air supply steel pipe is an external air supply steel pipe 14 close to the pile pipe outer wall, its lower end passes through the pile pipe wall, the lower end of the air supply steel pipe is bifurcated, and two to four air outlets 13 are separated. The air outlet is distributed on the inner wall of the pile pipe, and can be equipped with a one-way air outlet valve.

[0035] Apply pile driver of the present invention to carry out the construction steps of foundation treatment:

[0036] Step 1, the pile driver is in place, the pile tube is aligned with the pile position and the verticality is adjusted, and the variable diameter pile tube is used. The pile hole formed by the variable diameter pile tube is larger than the designed pile diameter, which is conducive to the discharge of the pile material from the pile tube to form a pile.

[0037] Step 2. Start the pile driver, so that the vibrating hammer head drives the pile pi...

Abstract

The invention is a vibro-pipe sinking air-pressure pile machine, where a pile pipe is vertically connected with the main frame of the pile machine, the upper end of the pile pipe is connected vibrating hammer head through flange, the vibrating hammer head connects with drive mechanism and is driven by electric machine, the pile pipe is a bottlelike variable-diameter pile pipe with diameters small up and big down, the side surface of the thin neck part of the variable-diameter is made with feed inlet, the inner wall of the pile pipe clinging to the bottom of the feed inlet is connected with a one-way valve, discharging outlet at the lower end of the pile pipe is connected with a one-way discharging gate, the pile pipe is connected with an air pressure material feeder, the air compressor of the air pressure material feeder is connected with high pressure air pipe, the high pressure air pipe is connected with an air feed steel pipe clinging to the pile pipe wall, and the air feed steel pipe extends down along the pile pipe wall, and the air outlet of the air feed steel pipe is located nearby the discharging outlet on the inner wall of the lower end of the pile pipe. And the lower end of the air feed steel pipe is forked into two to four air outlets, and the one-way discharging gate is built-in pile boot, valve pile boot or prefabricated pile tip. And it solves the problems that material discharging is not smooth and pile body is ununiform when making pipe sinking operation in salinized soil foundation and other high-water level soft foundations.

Description

(1) Technical field [0001] The invention relates to a construction machine for foundation treatment, in particular to a pipe sinking pile machine for saline soil foundation treatment. (2) Background technology [0002] In construction engineering, there are various types of foundation soil, and there are many types of pile drivers for foundation treatment for different soil types. The traditional tube sinking pile machine equipment is to vertically connect the pile tube on the main frame of the pile machine. The upper part of the pile tube is opened with a material inlet, the lower end of the pile tube is opened with a discharge port, the upper end of the pile tube is connected with a vibrating hammer, and the motor is connected The transmission mechanism also drives the vibrating hammer to drive the pile pipe to sink and pull out. However, when encountering soft foundations with low strength and high groundwater level such as saline soil, the silting phenomenon of the soft...
