Embodiment Construction
[0014] The features of the present invention and other relevant features are described in further detail below in conjunction with the accompanying drawings through the embodiments, so as to facilitate the understanding of those skilled in the art:
[0015] Such as Figure 1-4 , marks 1-11 in the figure are respectively: culvert section 1, oil volume controller 2, force distribution beam 3, oil top 4, oil return pipe 5, oil inlet pipe 6, manual control console 7, oil pipe 8, valve 9, terminal Head positioner 10.1, end positioner 10.2, spring 11, lever system 12.
[0016] Example: such as Figure 1-4 As shown, this embodiment specifically relates to a simultaneous oil jacking control system for uniform jacking of culverts and its application method. During construction, the jacked culvert 1 of civil engineering is huge in volume and heavy in weight. Two oil jacks 4 are jacked at the same time, because the friction force between the bottom plate of the jacking culvert section ...

The invention belongs to the technical field of jacking construction of bridges and culverts, and particularly relates to a synchronous-progress oil jack control system and an application method thereof. The detailed scheme of the invention is as follows: an oil volume controller, a stress distribution beam and an oil jack are sequentially arranged at the tail end of a culvert section along the longitudinal direction, wherein the oil volume controller is communicated with the oil jack through an oil intake pipe; and in the process of jacking the culvert section by the oil jack, the jacking progresses of all parts of the culvert section are different due to excursion, the volume intake amount of a valve in an oil intake pipe of the oil jack is controlled in a linkage manner by compressing or stretching a spring on the oil volume controller so as to keep the jacking progress of each part of the culvert section identical, and therefore whole excursion is avoided. The synchronous-progress oil jack control system disclosed by the invention has the advantages that the openness of the valve can be effectively controlled in a linkage manner by compressing or stretching of the spring, the problem of excursion caused by desynchrony of the jacking processes of the culvert section can be timely and automatically solved, the automatic synchronization is achieved and the manufacturing cost is lower.
Description
technical field [0001] The invention belongs to the technical field of bridge and culvert jacking construction, and in particular relates to a simultaneous oil jacking control system for uniform jacking of culvert joints and an application method thereof. Background technique [0002] During construction, the jacked-in culverts of civil engineering are huge in size and heavy in weight, and multiple oil jacks are often used to simultaneously jack them up. Since the friction between the bottom plate of the jacked-in culvert and the civil engineering is not uniform at each position, the implementation During the process, it is very easy to appear deviation phenomenon, or left deviation or right deviation or a certain degree of rotation phenomenon. This situation is extremely difficult to handle. The reason for this situation is that in the part with small friction force, the reaction force is small, and it is often easy to top. move. [0003] Therefore, in order to ensure th...
