Problems solved by technology

Among them, the routine process of leveling work is: leveling with a level, manually backing up the plate according to the elevation comparison, and repeatedly adjusting the height of the base until it is consistent with the design elevation, and the work is cumbersome
[0003] In addition, during the pipe jacking construction process, the weight of the pipe joints will also cause the pipe jacking base to settle, which will produce a certain vertical deviation and affect the construction quality of the pipe jacking construction.

Embodiment 1

[0039] refer to Figure 1 to Figure 3 , the present embodiment provides an automatic leveling base system, including a base 1, two sets of socket rails 2, two guide frames 3 with pipe section guide rails 7 on the upper parts, several jacks 4 with lug plates 5 on the upper parts, and several lift bar 6;

[0040] Two sets of socket rails 2 are arranged in parallel on the base 1;

[0041] The two guide frames 3 are sleeved on the socket track 2 respectively;

[0042] Several lifting rods 6 are arranged in parallel between the two guide frames 3, and each lifting rod 6 respectively passes through the two guide frames 3 to connect the two guide frames 3 together;

[0043] Both ends of the lifting rod 6 extend to the outside of the guide frame 3 and are respectively connected to the jack 4 arranged on the base 1 outside the guide frame 3 through the lug plates 5 .

[0044] In the automatic leveling base system of this embodiment, a lifting rod 6 is provided between the guide fram...

Embodiment 2

[0056] refer to Figure 1 to Figure 3 , this embodiment provides a method for using the self-leveling base system described in Embodiment 1.

[0057] The technical solution of a method for using an automatic leveling base system in this embodiment is as follows, including the following steps:

[0058] The first step is to install the self-leveling base system in the foundation pit of the working well;

[0059] In the second step, the pipe joint is placed on the guide rail 7;

[0060] The third step is to carry out pipe jacking construction on the pipe joints. During the construction process, the control system adjusts the lifting height of each jack 4 so that the elevation of the pipe jacking construction is within the set range;

[0061] In the fourth step, after the pipe jacking construction is completed, each jack 4 is lowered to separate the pipe section guide rail 7 from the end of the pipe section;

[0062] The fifth step is to remove the self-leveling base system.

Abstract

The invention provides an automatic-leveling base system and a using method thereof and aims to simplify the working process of mounting and leveling a base during pipe jacking construction and improve construction efficiency of pipe jacking construction. A lifting rod is arranged between guide frames and can adjust height of the same by adjusting height of a jack so as to adjust elevation of theautomatic-leveling base system, so that repeatedly artificial underboarding during leveling is avoided, and the working process of leveling is simplified. The elevation can be adjusted at any time, sothat the elevation can be adjusted timely to correct deviation when a base settles and generates vertical deviation during pipe jacking construction, and construction quality of pipe jacking construction is improved.

Description

technical field [0001] The invention belongs to the technical field of pipe jacking construction, and in particular relates to an automatic leveling base system and an application method thereof. Background technique [0002] In the pipe jacking construction, the installation time of the working well equipment is relatively long, and the installation time of the base is generally about 3 days. Base installation work mainly includes measurement, leveling, welding and other work. Among them, the routine process of leveling work is: leveling with a level, manually backing up the plate according to the elevation comparison, and repeatedly adjusting the height of the base until it is consistent with the design elevation, which is cumbersome. [0003] In addition, during the pipe jacking construction process, the weight of the pipe joints will also cause the pipe jacking base to settle, which will produce a certain vertical deviation and affect the construction quality of the pip...
