Problems solved by technology

[0004] (1) For strata with relatively hard geological conditions such as old clay or weathered rock distributed in the stratum, Larsen steel sheet piles or ordinary channel steel sheet piles are difficult to press into regardless of vibration or static pressure.
[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 pipeline repairs and maintenance that require rapid support.

Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] as attached figure 1 and 2 As shown, the present invention provides a quick support device for pipeline emergency repair, which includes a side support mechanism 1, an end support plate 2, a deployment mechanism 3, a quick support rod 4 and a limit block 5;

[0029] The side support mechanism 1 includes a fixed unit 11, a telescopic drive unit 12 and a movable unit 13; the movable unit 13 is connected with the fixed unit 11 through the telescopic drive unit 12; out or retract to meet the support requirements of different lengths of pits;

[0030] The end support plate 2 is located between the two side support mechanisms 1 , and its two ends are respectively hinged to the two side support mechanisms 1 . It includes: a left end support plate 21 and a right end support plate 22 . One end of the left end support plate 21 is hinged with the left side ...

Abstract

The invention discloses a rapid supporting device for emergency maintenance of a pipeline and an application method for the rapid supporting device. The device comprises side surface supporting mechanisms, end surface supporting plates, unfolding mechanisms and rapid supporting rods; the side surface supporting mechanisms are of plane structures and have the function of extending in the length direction of the plane; the two ends in the length direction of the two side surface supporting mechanisms are movably connected together through the two end surface supporting plates to form a polygonalgeometric support body; the two end surface supporting plates are hinged to each other through one side edges, and the other side edges of the two end surface supporting plates are hinged to the sidesurface supporting mechanisms; and the unfolding mechanisms are connected to the two side surface supporting mechanisms and enable the geometric support body to realize plane folding and complete unfolding through hinge points by means of linear extendable movement. According to the rapid supporting device, an operation pit in the emergency maintenance process of the pipeline can be quickly and efficiently supported, and collapse of the operation pit can be prevented.

Description

technical field [0001] The invention relates to an operation pit support device, in particular to a quick support device used for preventing the operation pit from collapsing during the emergency repair of pipelines. Background technique [0002] At present, the commonly used foundation pit support has the following types: (1) row pile support; (2) underground diaphragm wall support; (3) cement retaining wall; (4) steel sheet pile; (5) spray anchor (6) reverse left arch wall; (7) undisturbed soil grading; (8) support in foundation pit; (9) simple horizontal support; (10) reinforced concrete row piles, etc., or a combination of two or more methods protect. [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 ...
