Example 1

The prior art has the problem that the uneven settlement at the joint of a new roadbed and an old roadbed can not be controlled timely and accurately. In order to solve the defects of the prior art, embodiment 1 provides a device 01 for controlling uneven settlement at the junction of a new roadbed and an old roadbed, which comprises a liquid pumping device 1, a flow pressure valve 2, an old roadbed liquid storage box 3 and a new roadbed liquid storage box 4 as shown in fig. 1-2; the liquid pumping device 1, the flow pressure valve 2, the old road base liquid storage box 3 and the new road base liquid storage box 4 are communicated in sequence.

The schematic structural diagram of the construction and installation plane at the junction of the old and new roadbeds by using the device for controlling uneven settlement at the junction of the old and new roadbeds shown in fig. 1 is shown in fig. 2:

1. assembling the device:

the liquid extraction device 1 is installed on the old road edge 003 and can be used for extracting liquid, wherein the liquid can be sourced from a drainage ditch or an evaporation pool of the old road edge 003 or from a liquid storage container specially used for storing the liquid.

The flow pressure valve 2 can be automatically adjusted according to the pressure change condition, so that the interior of the device 01 for controlling the uneven settlement of the connection part of the old roadbed and the new roadbed reaches a pressure balance state. Specifically, when the water pressure is balanced (the internal liquid of the device 01 for controlling the uneven settlement at the connection of the old and new roadbed is in a static balance state), the flow pressure valve 2 is automatically adjusted to be in a closed state; when the water pressure is unbalanced (the internal liquid of the device 01 for controlling the uneven settlement at the connection part of the old roadbed and the new roadbed is in a flowing state), the flow pressure valve 2 is automatically adjusted to be in an opening state, so that the flow balance in the device is controlled.

The new roadbed liquid storage box 4 is fixed on the soil body of the new roadbed 002. Referring to fig. 2, the old road is excavated into three steps 004 before construction, and the old roadbed liquid storage box 3 is fixed on the soil body at the third step of the old roadbed 001. Wherein the installation requires that the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 are on the same horizontal line.

As shown in fig. 10 to 13, the new roadbed liquid storage box 4 comprises a box top through hole 40, a support plate 41, a floating ball 42, a floating rod 43 and a spring support 44; the support plate 41 is horizontally disposed; the floating rod 43 is arranged along the vertical direction, the top end of the floating rod 43 is fixed with the support plate 41, and the bottom end of the floating rod 43 is fixed with the floating ball 42; the rod body part of the floating rod 43 can be arranged in the box top through hole 40 in a vertically floating manner; a spring support 44 is fixed to the bottom of the new roadbed liquid storage box 4. The floating ball 42 and the floating rod 43 are fixed by welding, and the floating rod 43 and the support plate 41 are fixed by welding. The height of the float 43 can be designed to allow a +5mm lift for road engineering design.

As shown in fig. 2, when the assembly is completed (when the liquid is not injected yet), the support plate 41 is subjected to a downward self-weight, a downward pulling force by the float 43, and an upward supporting force by the top of the new foundation liquid storage tank 4. Under the three forces, the supporting plate 41 is in a force balance state, and the supporting plate 41 keeps a static state.

2. Injecting liquid:

after assembly is complete, the flow pressure valve 2 is manually opened, the pump 1 draws fluid (e.g., water from a drain in the old road bank 003), which flows through the pump 1 and flow pressure valve 2 in sequence, and finally fills the old and new road-based fluid reservoirs 3 and 4. At this time, the liquid levels in the old base liquid storage tank 3 and the new base liquid storage tank 4 rise.

When the liquid level in the new roadbed liquid storage box 4 rises to the height of interaction with the floating ball 42, the integral structure of the floating ball 42, the floating rod 43 and the support plate 41 is subjected to an upward buoyancy provided by the liquid, a downward gravity of the integral structure and an upward supporting force applied by the top of the new roadbed liquid storage box 4. Under the three forces, the whole structure is in a stress balance state, and at this time, the whole structure (including the support plate 41) formed by the floating ball 42, the floating rod 43 and the support plate 41 still keeps a static state.

As the liquid level rises, the displacement volume of the float 43 increases, the buoyancy increases, and the supporting force applied to the top of the new road base liquid storage tank 4 decreases. When the supporting force exerted by the top of the new liquid reservoir cartridge 4 is reduced to zero, the top of the new liquid reservoir cartridge 4 is no longer applied to the support plate 41 to support the force. The overall structure (including the support plate 41) formed by the float 42, the float rod 43 and the support plate 41 will have a tendency to move with the rising of the liquid level (the support plate 41 is in a critical rising state). At this time, the flow pressure valve 2 is manually closed, and with the closing of the flow pressure valve 2, the internal liquid of the device 01 for controlling uneven settlement at the junction of the old and new road beds enters a static equilibrium state, and the pressure difference of the liquid between the old road bed liquid storage box 3 and the new road bed liquid storage box 4 is zero. At this time, the water pressure in the new roadbed liquid storage box 4 can be measured through the box top through hole 40 of the new roadbed liquid storage box 4, and the critical water pressure of the flow pressure valve 2 is set, and the flow pressure valve 2 is automatically opened when exceeding the critical water pressure, and is automatically closed when being smaller than the critical water pressure. And after the initial setting is finished, completing construction of a group of devices 01 for controlling uneven settlement at the joint of the new roadbed and the old roadbed.

A plurality of groups of devices 01 for controlling the uneven settlement of the joints of the old and the new roadbeds can be arranged according to the actual situation of site construction, and the steps are repeated until the construction of the whole device consisting of the plurality of groups of devices 01 for controlling the uneven settlement of the joints of the old and the new roadbeds is completed.

And then, normally constructing the road, and after the construction and maintenance are finished, starting to operate an integral device consisting of a plurality of groups of devices 01 for controlling the uneven settlement of the joints of the new and old roadbed.

3. Operation of the apparatus

After the installation is completed, the internal liquid of the device 01 for controlling uneven settlement at the joint of the new roadbed and the old roadbed enters a static equilibrium state, and at the moment, the pressure difference of the liquid between the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 is zero.

If the uneven settlement phenomenon does not occur at the joint of the new roadbed and the old roadbed, the internal liquid of the device 01 for controlling the uneven settlement at the joint of the new roadbed and the old roadbed enters a static balance state, no pressure difference exists between the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4, and the flow pressure valve 2 keeps a closed state.

When the new roadbed 002 subsides and the difference between the settlement rates of the old roadbed 001 and the new roadbed 002 is large, the new roadbed liquid storage box 4 sinks along with the settlement of the new roadbed 002, a height difference is formed between the new roadbed liquid storage box 4 and the old roadbed liquid storage box 3, and the liquid in the old roadbed liquid storage box 3 automatically flows into the new roadbed liquid storage box 4. At this time, the flow pressure valve 2 is automatically opened when detecting that the critical water pressure is exceeded, and the fluid pumping device 1 supplies fluid to the old road base fluid storage box 3 and the new road base fluid storage box 4 to provide the fluid pressure. Along with the sinking of the new roadbed liquid storage box 4, the liquid storage amount in the new roadbed liquid storage box 4 increases, the liquid level rises, the integral structure (including the support plate 41) formed by the floating ball 42, the floating rod 43 and the support plate 41 has a rising movement trend along with the rising of the liquid level, at the moment, a settled soil layer is arranged above the support plate 41, and the settled soil layer applies a downward pressure to the support plate 41, and an upward buoyancy, a downward integral structure gravity and a downward pressure applied by the settled soil layer are provided by the liquid received by the integral structure formed by the floating ball 42, the floating rod 43 and the support plate 41; when a new stress balance relationship is established by the three forces, the integral structure (comprising the supporting plate 41) formed by the floating ball 42, the floating rod 43 and the supporting plate 41 does not continuously rise any more, the internal liquid of the device 01 for controlling uneven settlement at the joint of the new roadbed and the old roadbed enters a static balance state again, and the flow pressure valve 2 is closed. The support force provided by the support plate 41 to the layer of settled soil is equal to the pressure applied by the layer of settled soil to the support plate 41.

That is to say, after the uneven settlement of new and old road bed junction appears, new road bed liquid storage box 4 sinks, and new road bed liquid storage box 4's stock solution volume increases, and the liquid level rises for floater 42 drives the float bar 43, backup pad 41 upward movement, and backup pad 41 provides the holding power for subsiding the soil horizon, thereby reduces the settlement volume of new road bed 002 side.
