Problems solved by technology

[0003] Under the traditional construction technology, the section steel support commonly used in underground engineering has problems such as inaccurate positioning and difficulty in adjusting the position. Exceeding its allowable range, it is impossible to effectively control the surrounding rock, and in severe cases, it will cause instability of the tunnel face and tunnel collapse, resulting in major economic losses

Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0050] A set of assembly equipment and construction technology suitable for adjusting the arch frame of underground engineering, including a positioning operation trolley 3 for adjusting the arch legs on the ground, a support frame 2 for adjusting the position of the arch, and a Laser aligner 18 for vault and arch feet on both sides.

[0051] The positioning operation trolley 3 adjusts the arch legs, specifically including the bottom load-bearing structure composed of tires 5, jacks and platforms 7, the middle support structure composed of rotatable and fixed position adjustment jacks 10, and the upper clamp for constraining the arch legs. Support structure11. Wherein the bearing structure at the bottom of the positioning operation trolley 3, on the basis of the general tire 5 and the platform structure, four bottom jacks 6 are welded around the platfo...

Abstract

The invention provides an underground engineering arch-shaped support assembling, positioning and adjusting system, adjusting bogies and an adjusting method. The assembling, positioning and adjusting system comprises an arch apex adjusting device arranged at an arch apex and used for adjusting height of the same, the adjusting bogies arranged at two arch legs and a laser alignment system, and the adjusting bogies are used for adjusting and positioning the arch legs; each adjusting bogie particularly comprises an upper-portion holding part, a position adjusting supporting part and traveling wheels, each upper-portion holding part is provided with an upward opening portion for holding the corresponding arch leg, each position adjusting supporting part can extend and contract axially, the top of each position adjusting supporting part is fixedly connected with the bottom of the corresponding upper-portion holding part while the bottom of the same is fixedly connected with a load bearing platform in a manner of being capable of rotating along a vertical plane, and the traveling wheels are arranged at the bottom of the corresponding load bearing platform and used for preliminary positioning of an arch-shaped support; the laser alignment system comprises laser transceivers respectively arranged on the arch apex adjusting device and the adjusting bogies and transmitting along the radial direction of the arch-shaped support, and positioning accuracy of the arch-shaped support is judged through laser receiving state of the laser transceivers and position relation with a vertical positioning hammer arranged on the arch-shaped support.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction, in particular to an underground engineering arch assembly positioning adjustment system, an adjustment trolley and an adjustment method. Background technique [0002] With the rapid development of the scale and speed of underground engineering construction, higher requirements are put forward for the construction progress and quality, which greatly promotes the gradual expansion of the scale of transportation infrastructure construction and the rapid development of expressway construction. There is a big improvement in terms of scale. [0003] Under the traditional construction technology, the section steel support commonly used in underground engineering has problems such as inaccurate positioning and difficulty in adjusting the position. If it exceeds its allowable range, the surrounding rock cannot be effectively controlled, and in severe cases, it will cause inst...
