Embodiment Construction
[0050] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.
[0051]Assuming that the width between the road sidewalk side stones is 30m, divide the 30m into A, B, and two sections. The specific width of each section can be adjusted according to the road width. First construct section A, and leave section B to ensure two-way four-lane traffic; then For construction section B, leave section A to ensure two-way four-lane traffic; in order to ensure sufficient working surface, 1 meter of sidewalk can be temporarily borrowed respectively.
[0052] The construction machinery and equipment used are as follows:
[0053] Diaphragm wall grooving machine, bored pile drilling rig, crawler crane, truck crane, electric welding machine, steel bar processing machinery, submersible pump and mud pump, concrete vibrating machine, etc.
[0054] Specifically include the following steps:
[0055] (1) Divide the construction ground...

Abstract
The invention discloses a double-amplitude type hybrid construction method for underground engineering. The method comprises the following steps: (1) dividing a construction ground into two sections, namely, a section A and a section B; (2) sealing up the section A, constructing the section A, excavating the earthwork, and constructing an underground continuous wall so as to obtain a section A wall plate; (3) excavating the surface earthwork and manufacturing a section A top plate; (4) refilling the earthwork of the section A, constructing the section B, excavating the earthwork, and constructing an underground continuous wall so as to obtain a section B wall plate; (5) excavating the surface earthwork till the base layer of a bottom plate, and manufacturing a section A bottom plate and a section B bottom plate; (6) manufacturing a section B top plate; and (7) refilling the earthwork of the section B.
Description
technical field [0001] The invention relates to a construction technology, in particular to a double-width mixed construction method for underground engineering. Background technique [0002] Domestic urban development is increasingly facing problems such as land shortage, traffic congestion, environmental pollution, energy shortage, and vulnerability to disaster prevention. The way of urban space expansion is shifting from "ground" to "three-dimensional". More and more municipal projects and civil projects choose to develop underground, and a large number of large underground buildings have been newly built. However, the development site of underground buildings is often located in the center of the city. During the construction period, the closed road will put a lot of pressure on the traffic, especially when there are no surrounding roads for vehicles to detour, the road closed construction will cause urban traffic function of paralysis. [0003] The current common meth...
