Problems solved by technology

This method not only requires a spacious site and a place to collect slag, but also must wait for the slag to be excavated before proceeding to the next process, and the construction progress is slow.
In addition, large-scale mechanical cooperation is required, which increases the cost

Embodiment 1

[0042] Such as figure 1 and figure 2 As shown, the present invention provides a kind of vertical shaft rapid construction method, comprises the following steps:

[0043] Step 1, drilling: measure and determine that the pilot hole 2 is obtained by drilling with a rotary drilling rig at the center of the section of the pre-excavated shaft 1;

[0044] Step 2, excavation of the cross passage: excavate the cross passage 3 at the bottom of the pre-excavated shaft 1, and the cross passage communicates with the bottom of the guide hole 2;

[0045] Step 3, shaft excavation: take the guide hole 2 as the center and adopt the full-section excavation method to excavate the shaft 1 until the bottom of the shaft 1 communicates with the transverse passage 3; Fall into the cross channel 3 and be transported to the slag yard by the slag truck.

Embodiment 2

[0047] Further improvement on the basis of Example 1, the diameter of the guide hole 2 is 1.2-1.5m. In the step 3, the shaft lock ring beams are firstly constructed between the excavated shafts 1 . 3. A quick construction method for a shaft according to claim 1, characterized in that in step 2, the end face of the excavated transverse channel 3 and the side wall of the guide hole 2 are in the same vertical direction; in step 3 , using an excavator 20 to excavate along the circumferential direction on the annular rock and soil between the outer wall of the pilot hole 2 and the inner wall of the pre-excavated shaft 1 .

Embodiment 3

[0049] Further improvement on the basis of Example 2, the construction method also includes removing clogged stone materials in the guide hole 2 by means of water injection, pressurization or blasting.

Abstract

The invention discloses a vertical shaft rapid construction method, including the following steps: step 1, drilling, including measuring and determining a section center of a pre-dug vertical shaft, using a rotary drilling rig to drill to obtain a guide hole; step 2, digging a cross channel, including digging a cross channel on the bottom of the pre-dug vertical shaft, the cross channel being communicated with the bottom of the guide hole; step 3, digging a vertical shaft, including using the guide hole as the center of a circle, using a full-face tunnelling method to dig the vertical shaft, until the bottom of the vertical shaft is communicated with the cross channel. In a vertical shaft digging process, slag falls into the cross channel through the guide hole, and is conveyed to a slag yard by slag cars. After the vertical shaft is dug, a lifting device is not needed for independent deslag. Slag directly falls to the bottom of the vertical shaft through the guide hole, so that construction days are reduced and cost is greatly reduced. In addition, a special anti-blocking mechanism is used to effectively prevent the guide hole from being blocked, and construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of underground engineering, in particular to a rapid shaft construction method and equipment. Background technique [0002] With the development of the city, the urban traffic is becoming more and more congested. In recent years, the country has vigorously developed urban subways, and the subway industry has sprung up like mushrooms, developing rapidly across the country. Due to the characteristics of comfort, safety, speed, large passenger capacity, and fast departure time, the subway has become more and more popular among citizens and has become an indispensable means of transportation in the city. Due to the limitation of geographical location and geological conditions, some subway stations and auxiliary structures are buried deeply, so underground excavation method is required for construction. And in order to meet the ventilation and evacuation conditions of the station, the auxiliary structures are e...
