Description

Technical Field

[0001] The present invention relates to the field of translation of buildings and heavy equipment, etc., and specifically relates to a continuous jacking method based on steel slides. Background Art

[0002] With the development of society and continuous adjustment of planning, more and more buildings and heavy equipment, etc. (hereinafter referred to as "superstructure") need to be translated. During the translation process, due to the limited stroke of the hydraulic jacks used for jacking, repeated jacking is likely to cause fatigue damage to the superstructure; and the jacking speed is too slow, with high requirements for foundation treatment; in addition, the construction period of repeated jacking is too long and the efficiency is too low.

[0003] Therefore, a continuous jacking and translation method based on steel slides is studied. This method is a continuous jacking without interruption and repeated pauses, which can push the superstructure to translate continuously, avoid repeated loading on the superstructure, reduce the foundation settlement, improve the jacking and translation efficiency, and effectively improve the safety guarantee of the translation project. It is a more efficient and economical construction method with very good application prospects. Summary of the Invention

[0004] The core idea of the present invention is to install tracks with the function of providing reaction force on the steel slides, and install continuous jacking devices on the tracks. The continuous jacking devices can automatically lock the tracks, and control the two groups of jacking devices to jack alternately through a software system, and control the smooth transition of the force conversion process to achieve the continuous jacking and translation of the superstructure.

[0005] To achieve the above object, the present invention adopts the following devices:

[0006] I. Steel slides, as the translation sliding surface of the building, the four sides of the steel slides are made into a structure similar to mortise and tenon joints. The steel slides can be spliced in the longitudinal and transverse directions, so that multiple steel plates are connected into a whole to form a large steel plate, and the building can translate on this slide. At the same time, the steel plates are also easy to remove, facilitating reuse next time.

[0007] II. Tracks, which provide reaction force for the continuous jacking devices. Reaction plates are arranged at regular intervals on the tracks. The tracks and the steel slides are connected by screws, which is convenient for connection, disassembly and changing positions.

[0008] III. Seam tracks, which connect the two tracks on the two steel slides and can strengthen the strength of the joint of the steel slides at the same time.

[0009] IV. Continuous pushing device. A horizontal jack is installed in the continuous pushing device, and a rotating block for automatically locking the track is installed at the tail of the continuous pushing device, which has a one-way rotation limit function. When the jack in the continuous pushing device extends, the rotating block locks the track, and at this time, pushing can be carried out. When the jack in the continuous pushing device retracts, the rotating block can rotate freely, enabling the continuous pushing device and the track to move relative to each other freely, realizing the retraction of the piston rod of the jack and preparing for the previous pushing.

[0010] A continuous pushing and translation method based on a steel slideway according to the present invention comprises the following steps:

[0011] Step 1: Lay the steel slideway and symmetrically install the steel slideway on the ground under the superstructure.

[0012] Step 2: Install steel corbels and steel rollers on the superstructure.

[0013] Step 3: Install a track and a joint track on the steel slideway along the translation direction, and install a reaction plate at a certain interval on the track.

[0014] Step 4: Install two sets of continuous pushing devices on the track.

[0015] Step 5: Start pushing to extend the horizontal jack of the first set of pushing devices, and keep the pushing devices of the second set stationary and move forward together with the superstructure.

[0016] Step 6: After the rotating block of the second set of continuous pushing devices automatically crosses the next reaction plate on the track, control the hydraulic system through software to quickly extend the horizontal jack on the second set of continuous pushing devices, quickly establish a reaction force with the track and then push at a normal speed. At this time, quickly retract the horizontal jack on the first set of continuous pushing devices.

[0017] Step 7: Continuously extend the horizontal jack of the second set of pushing devices. At this time, the piston rod of the horizontal jack on the first set of continuous pushing devices continuously retracts quickly and moves forward together with the superstructure at the same time.

[0018] Step 8: After the rotating block of the first set of continuous pushing devices automatically crosses the next reaction plate on the track, control the hydraulic system through software to quickly extend the horizontal jack on the first set, quickly establish a reaction force with the track and then push at a normal speed. At this time, quickly retract the horizontal jack on the second set of continuous pushing devices.

[0019] Step 9: Continuously extend the horizontal jack of the first set of pushing devices. At this time, the piston rod of the horizontal jack on the second set of continuous pushing devices continuously retracts quickly and moves forward together with the superstructure at the same time.

[0020] Step 10: Repeat the above steps until the superstructure is translated to the preset position.

[0021] The number of each group of continuous jacks can be arranged in several according to the size of the superstructure. For example, Figure 4 taking two continuous jacks in each group as an example, two groups of alternating jacking can achieve continuous and uninterrupted jacking construction.

[0022] A continuous jacking and translation method based on a steel slideway involved in the present invention has the following beneficial effects:

[0023] A continuous jacking and translation method based on a steel slideway disclosed by the present invention can continuously jack and translate a building on the steel slideway without a pause process, eliminating the need for traditional replacement of bearings and addition of pads, saving time and a large amount of manpower and material resources, avoiding repeated loading on the superstructure, reducing the foundation settlement amount, and being a more efficient and economical construction method with very good application prospects.
