Embodiment Construction

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] Such as figure 1 As shown, the construction method of the tunnel shallow buried section passing through the dense living area under the present invention comprises the following steps:

[0031] Step S101, mechanical cutting, using a horizontal geological drilling rig to vertically drill two cutting holes, the diameter of the cutting holes is 600mm, the hole spacing is not less than 300mm, and the drilling depth is 10-15m.

[0032] Step S102, drilling shock-absorbing holes, using a crawler-type pipe shed drilling machine to drill a row of shock-absorbing holes along the 120° range of the vault,...

Abstract

The invention discloses a construction method for a shallowly buried tunnel segment passing through an intensive residence area from the below. The method includes mechanical underholing, damping holedrilling, drill hole blasting, mechanical slug removal, and tunnel support. According to the invention, the construction safety of the tunnel itself and the safety of the residential communities above the tunnel are taken into comprehensive comprehension in the construction method for the shallowly buried tunnel segment passing through roads and also the residential communities from the below comprehensively. Effective measures are taken during the construction process for preventing inner-tunnel structure settlement and settlement of building above, and dynamic monitoring is performed. The construction method is safe, reasonable, economical efficiency and quick. The safety of the construction process is ensured and normal operation of the intensive residence area in a city is also ensured.

Description

technical field [0001] The invention relates to the technical field of design and arrangement of tunnels, in particular to a construction method for passing through a dense living area under a shallow buried section of a tunnel. Background technique [0002] The existing tunnel blasting technology is a universal blasting technology, but when it is applied to the shallow buried section of the tunnel, it is difficult to grasp the impact of the blasting, and it cannot guarantee that the roof and other buildings of the shallow buried tunnel will not be damaged. Blasting, on the one hand, is limited by the temperature environment, and on the other hand, there are certain irrationality in terms of progress and economy. Contents of the invention [0003] In order to solve the technical problems existing in the prior art, such as the inability to guarantee the safety of residents, the undamaged houses, strict construction environment requirements, and economic efficiency, in the c...
