Problems solved by technology

[0003] Although the traditional walking-type jacking construction method can achieve accurate jacking control, there is a fall back temporary pier in the process, so the compression deformation of the temporary pier directly affects the safety of the superstructure, and the compression deformation of the temporary pier is uneven It is mainly caused by the lack of compactness of the support pad itself, the uneven load weight on the upper part, and the difference in the overall stiffness of the pier, so the compression deformation of the pier cannot be avoided. Directly affect the efficiency of jacking construction

Embodiment Construction

[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Please combine Figure 1 to Figure 4 As shown, the synchronous alternate jacking construction system used in the present invention includes a sliding base 1, an oil cylinder mechanism 2, a jacking cylinder mechanism and a displacement sensor 3, and several jacking cylinders 4 are arranged at the bottom of the sliding base 1. In this embodiment, there are four jacking cylinders 4, which are used to lift or lower the sliding base 1 as a whole. The displacement sensor 3 is located on the other end of the upper surface of the sliding base 1, and adopts a pull wire type displacement sensor, which is fixed on the sliding base 1 through threads. The step stroke of the push cylinder mechanism, in addition, a sensor can be separately arranged above the push cylinder mechanism to monitor the jacking of the push cylinder mechanis...

Abstract

The invention discloses a synchronous and alternating pushing construction method. A synchronous and alternating pushing construction system is adopted and comprises a sliding base, an oil cylinder mechanism, a pushing oil cylinder mechanism and a displacement sensor, and an existing pushing technique is replaced by using the system. According to the method, by means of synchronous and alternating pushing work, the falling back process in traditional pushing work can be avoided, and the condition that a pushed object is damaged when the pushed object generates deviation in the falling back process is prevented.

Description

technical field [0001] The invention relates to the technical field of building jacking, and more specifically, to a method for synchronous and alternate jacking construction. Background technique [0002] In the existing construction process, walking-type jacking construction is a commonly used construction method when the object to be pushed is translated in the longitudinal direction. After the traditional walking-type jacking construction completes a pushing stroke, the upper load needs to be Put it on the temporary support pier, retract the jacking equipment after it is empty, and lift the underpinning to replace the upper load again for jacking, and repeat until all the jacking construction is completed. [0003] Although the traditional walking-type jacking construction method can achieve accurate jacking control, there is a fall back temporary pier in the process, so the compression deformation of the temporary pier directly affects the safety of the superstructure, ...
