Embodiment 1

[0034] Example 1, such as Figure 1-3 As shown, a caisson shaft tunneling machine includes a tunneling system, a control and detection system, and a slag discharge system 9. A pipe joint pressure-lifting device 1 is provided on the wellhead ring beam on the ground, and the pipe joint pressure-lifting device can realize the whole The hoisting or pressurization of the wellbore has the characteristics of stable lifting or sinking, safety, adjustable speed, and convenient maintenance, so that the wellbore sinks smoothly. The excavation system includes a propulsion device 3, a slewing support 5, a slewing platform 6 and an excavation device 7. The upper part of the propulsion device 3 is connected to the hydraulic power system on the ground, and the propulsion device is used for radial stabilization and axial propulsion of the excavation system. . The lower part of the propulsion device 3 is provided with an equipment platform 4, the equipment platform 4 is connected with the slew...

Embodiment 2

[0036] Example 2, such as Figure 4-6 As shown, a caisson method shaft boring machine, the first spreader mechanism includes several first stretcher cylinders 303, several second stretcher cylinders 306, and the second stretcher mechanism includes several third stretcher cylinders Oil cylinder 307, the first tensioning cylinder 303 is evenly arranged on the tensioning flange 301 along the circumferential direction, and the first tensioning cylinder 303 is stretched radially; the second tensioning cylinder 306 is evenly arranged on the outer cylinder 304 along the circumferential direction , and the second stretching cylinder 306 expands and contracts in the radial direction, and the third stretching cylinder 307 is evenly arranged on the outer circumference of the equipment platform 4 along the circumferential direction, and the third stretching cylinder 307 expands and contracts in the radial direction for supporting the equipment platform ; The first stretching oil cylinder ...

Embodiment 3

[0040] Embodiment 3, a construction method of a caisson shaft boring machine, comprising the following steps: S1: positioning the caisson to be excavated, leveling the site, hardening the surrounding parts of the wellhead, forming a ring beam at the wellhead, and forming a ring beam at the wellhead Fix the pipe joint pressure-lifting device on the upper part, and lay a cushion and level the blade foot part;

[0041] S2: The excavation device, slewing platform, slewing support, equipment platform, propulsion system, control and detection system are installed and debugged in sequence in the open space; since the installation and debugging of the mechanical structure of the roadheader has nothing to do with the pipe joints, this part can be installed in the submerged It is completed in advance before the well starts, so the preparation time for caisson operation is greatly saved and the production efficiency is improved.

[0042] S3: Install the blade foot pipe joint and the foun...

Abstract

The invention discloses a shaft boring machine by an open caisson method and a construction method thereof, and solves the problems of low mechanization degree, difficult disassembly and assembly andlow working efficiency of a shaft excavation device in the prior art. The shaft boring machine by the open caisson method comprises a tunneling system, a control detection system and a slag dischargesystem. A pipe joint pressure lifting device is arranged on a wellhead ring beam on the ground. The tunneling system comprises a propulsion device, a rotary support, a rotary platform and an excavation device. The upper part of the propulsion device is connected with a hydraulic power system on the ground, and the lower part of the propulsion device is provided with an equipment platform. The equipment platform is connected with the rotary support, and the rotary support is connected with a driving device arranged on the equipment platform. The upper part of the rotary platform is connected with the rotary support, and the excavation device is arranged at the lower part of the rotary platform. According to the shaft boring machine by the open caisson method, the step-by-step excavation ofthe excavation device is realized through the propulsion device, and the efficient and safe excavation is realized through the tightening and stabilization of the excavation device. The shaft boring machine can be quickly disassembled and assembled in the process of entering and exiting the well, thereby saving the construction period and improving the well-forming efficiency.

Description

technical field [0001] The invention relates to the technical field of underground shaft construction, in particular to a caisson shaft boring machine and a construction method thereof. Background technique [0002] Shaft engineering is widely used in the field of underground space development, such as shield launching, receiving shafts, mining shafts, water conservancy engineering shafts, tunnel ventilation shafts, underground fortification shafts, underground three-dimensional garage shafts, etc. At present, manual excavation is still commonly used in shaft excavation. While excavating, the well wall is cast in place or the prefabricated shaft is sunk to form support. The degree of mechanization and automation is generally low, the safety risk of the construction process is high, and the overall construction cost is high. . [0003] Existing shaft drilling rigs with a high degree of mechanization cannot be disassembled quickly, requiring personnel to frequently enter the ...
