Problems solved by technology

[0004] (1) For strata with relatively hard geological conditions such as old clay or weathered rocks distributed in the stratum, it is difficult to press Larsen steel sheet piles or ordinary channel steel sheet piles into them no matter the way of vibration or static pressure is used.
[0005] (2) The method of using steel sheet piles requires piling and piece-by-piece splicing, and the efficiency is low. It is suitable for routine operations such as pipeline laying after excavation, but it is not suitable for emergency repair and maintenance of pipelines that require rapid support

Embodiment 1

[0041] See attached figure 1 , this embodiment provides a pipeline emergency repair support unit, including: a main support plate set 1, an end face support plate 2, a main support rod 4 and a diagonal support rod 5.

[0042] See attached figure 2 , the main support plate set 1 includes: two main support plates 11 arranged oppositely, and the two main support plates 11 can generate relative displacements to realize the lateral expansion and retraction of the main support plate set 1 . Moreover, each main support plate 11 is nested together by two relatively sliding plates, so that the longitudinal expansion and contraction of the main support plate 11 can be realized.

[0043]In this example, the main support plate group 1 realizes horizontal expansion and contraction through the scissors mechanism 3; specifically: the scissors mechanism 3 is arranged between the opposite surfaces of the two main support plates 11, including: scissors connecting rod 32 1. The scissor oil cy...

Embodiment 2

[0048] On the basis of Embodiment 1, the pipeline emergency repair support unit can be spliced ​​and used by multiple units, and can be spliced ​​in the height direction or vertically, so as to meet the support needs of the emergency repair operation pit to the greatest extent.

[0049] See attached Figure 6 When two pipeline emergency repair support units are spliced ​​along the height direction, the adjacent road emergency repair support units are connected and fastened through the height connector 6 .

[0050] See attached Figure 7 , the height connector 6 includes: a twist lock 61, a nut 62 and a spring pin 63; the twist lock 61 includes a screw threaded with the nut 62 and a lock head connected to one end of the screw rod; where the screw rod of the twist lock 61 protrudes from the nut 62 The center hole is provided with a spring pin 63 at the end of the screw rod of the twist lock 61 protruding from the center hole end of the nut 62, and the spring pin 63 prevents the...

Abstract

The invention relates to a pipeline emergency repair and maintenance device, in particular to an operation pit supporting device. A supporting unit for pipeline emergency repair comprises a main supporting plate group, two end surface supporting plates, a main supporting rod and four inclined supporting rods, wherein the main supporting plate group comprises two main supporting plates; the two endsurface supporting plates are arranged at the opposite end surfaces of the main supporting plates under an unfolded state of the main supporting plates; the two end surface supporting plates and thetwo main supporting plates form a rectangle frame structure; the main supporting rod is arranged between the two main supporting plates; and the four inclined supporting rods are arranged at four corners formed by the two end surface supporting plates and the two main supporting plates. According to the supporting unit for pipeline emergency repair, the main supporting plates are connected with the end surface supporting plates into a whole under the unfolded state of the main supporting plates, then the inclined supporting rods and the main supporting rod are installed, the bearable frame structure is formed, and finally the supporting unit can be integrally hoisted into an operation pit to play a supporting effect without piling; and the supporting unit for pipeline emergency repair is specially suitable for working conditions of pipeline emergency repair.

Description

technical field [0001] The invention relates to pipeline emergency repair and maintenance, in particular to a working pit support device. Background technique [0002] At present, foundation pit support usually adopts any one or any combination of the following forms: (1) row pile support; (2) underground diaphragm wall support; (3) cement retaining wall; (4) steel sheet pile; (5) (6) Inverted left arch wall; (7) Undisturbed soil grading; (8) Support in foundation pit; (9) Simple horizontal support; (10) Reinforced concrete row piles. [0003] The steel sheet pile is a simple maintenance wall, which is composed of channel steel buckled front and back or side by side. Its main features are: the channel steel has good durability, and the channel steel can be pulled out and recycled after the foundation pit construction is completed and backfilled, and a support or anchor is generally set on the top. Since steel sheet piles can be recycled, resources are saved, economical and...
