Problems solved by technology

[0003] Similarly, in bridges, tunnels, buildings and other projects with foundations (foundations) and supports on the foundations (foundations), the settlement of the foundations (foundations) mentioned above will affect the quality, safety and use of the entire project. big question of time
[0004] However, at present, there is no effective measure to completely cure the disease in the prior art.

Embodiment 1

[0036] see figure 1 , shows the packing type displacement adjustment compensation device of the present invention, which is set between the foundation (foundation) and the supported objects (sleepers, bridge pillars, buildings, etc.) in use, specifically including the first support 2 and the second support Part 1, at least a part of the second supporting part 1 can be inserted into the opening formed by the first supporting part 2, and can relatively move axially.

[0037] The first support 2 is preferably a cylinder with a closed bottom, and the inside of the second support 1 is formed with a space for accommodating fillers. There is at least one opening on the bottom plate of the second support 1 for making the filler inside it Pass through and drop into the gap between the inner and outer sleeves. The top of the second supporting member 1 has an upper cover plate 4 for connecting with the supported object.

[0038] The packing type displacement adjustment compensation dev...

Embodiment 2

[0050] The structure of the first embodiment of the present invention is different from that of embodiment 1 in that a sleeve is added, and the height adjustment value of the multi-stage telescopic structure in embodiment 2 is larger, which can make full use of the advantage that the filling amount can be supplemented.

[0051] Specifically, there is at least one layer of sleeve 10 between the second support 1 and the first support 2 ( image 3 Take an intermediate sleeve as an example for illustration), wherein the second support member 1 and the first support member 2 are basically the same in structure as the second support member 1 and the first support member 2 in Embodiment 1 respectively, and the sleeve 10 There are openings at the top and bottom, and any two adjacent parts of the second support 1 , the multi-layer sleeve 10 and the first support 2 can move relative to each other along the axial direction, thereby realizing the height adjustment of the device.

[0052] ...

Embodiment 3

[0063] Figure 6-7 It shows the structural diagram of the third embodiment of the present invention, the second support 1 is in contact with the foundation, and the first support 2 is connected with the sleeper or other supported objects. There is no filler inside the second support member 1 . The first supporting member 2 is provided with an opening, and is connected with the stuffing box 5 outside through the opening.

[0064] A pressurizing mechanism is arranged inside the stuffing box 5 , such as a spring plate structure, etc., to apply pressure to the stuffing so that the stuffing can quickly flow into the first support member 2 of the cylinder.

[0065] In another solution, the second support 1 and the first support 2 can be turned upside down, that is, the first support 2 of the cylinder is in contact with the foundation, and the second support 1 is connected with the sleeper or other supported parts. At this time, the stuffing box 5 is also placed on the top, and com...

Abstract

The invention discloses a filling-type displacement adjusting and compensating device. The filling-type displacement adjusting and compensating device comprises a first supporting part and a second supporting part; the filling-type displacement adjusting and compensating device is characterized in that at least a part of the second supporting part is arranged in an opening of the first supporting part and can move in the axial direction; and the device further comprises a filler structure, wherein the filler structure communicates with a space formed after the axial movement. The filling-type displacement adjusting and compensating device disclosed by the invention is widely used in a rail transit project or other projects under conditions of soft soil foundations and special unfavorable geology.

Description

technical field [0001] The invention belongs to a height adjustment device, in particular to a filler-type displacement adjustment and compensation device for foundation anti-subsidence of buildings built on foundations, such as roads, bridges, culverts, tunnels, buildings, etc. Background technique [0002] In rail transit, in order to ensure the safety, stability and comfort of train operation, the top surface of the rail is required to have a smoothness index that meets the relevant standards. Due to the differences in engineering geological conditions in various regions, in areas with poor engineering geological conditions, the main structure will often settle after completion due to the bearing capacity of the foundation or other special circumstances, or it will be uneven under the initial construction conditions, resulting in uneven track structures, which will affect The safety, stability and comfort of train operation have become one of the main problems of urban ra...
