Description

Technical Field

[0001] The present invention relates to the technical field of geotechnical investigation, and in particular to a self-stabilizing temporary channel paving device for soft soil areas and an application method thereof. Background Art

[0002] my country is blessed with abundant rainfall, and soft soil is widely distributed, commonly found in coastal areas, plains, inland lake basins, depressions, and along river banks. With the gradual improvement of infrastructure planning systems across the country, the number of engineering construction projects in various regions has increased year by year. From survey and design to construction, engineering construction activities often need to be carried out in soft soil areas. Soft soil has a high natural water content, high compressibility, and low bearing capacity. For temporary projects that need to be active in soft soil areas, such as survey work and temporary roads, if foundation treatment is required, the cost will be too high and will seriously affect the local original environment. If treatment is not carried out, the work progress and construction convenience will be affected.

[0003] The existing working mode mostly uses bamboo rafts, wooden boards, etc. to be laid on the surface of soft soil to facilitate temporary engineering construction activities on it. Due to the creep and thixotropy of soft soil, as the construction activities proceed, the soft soil is repeatedly affected by external forces, and the bearing capacity will gradually decrease, seriously affecting the safety of the operation. Affected by the unstable working environment, the quality of engineering construction is also difficult to control, and different construction activities have different usage time and application scope of the construction site. Summary of the Invention

[0004] The purpose of the present invention is to provide a self-stabilizing temporary channel paving device and its application method for soft soil areas based on the above-mentioned deficiencies of the prior art. By excluding the soft soil around the cavity to fully utilize the buoyancy generated by the soft soil, the bearing capacity is increased. At the same time, by setting a lateral embedded body to limit the plane displacement, the bearing capacity and stability of the temporary channel are significantly improved.

[0005] The purpose of the present invention is achieved by the following technical solutions:

[0006] A self-stabilizing temporary channel paving device for soft soil areas is characterized in that: the temporary channel paving device includes a panel frame, a sewage discharge chamber and a stabilizing rod, wherein the panel frame is installed above the sewage discharge chamber, a panel is installed on the panel frame, and the area above the panel serves as a channel, the stabilizing rod is installed on the panel frame and passes downward through the sewage discharge chamber, and a transverse embedded body is provided on the stabilizing rod, and the transverse embedded body can be extended and retracted in the horizontal direction.

[0007] An inflation tube is provided inside the rod body of the stabilizing rod, and the inflation port of the inflation tube is opened on the surface of the panel frame. The transverse embedded body is a telescopic body, which is connected to the inflation tube. The telescopic body can be extended horizontally under the inflation of the inflation tube to be embedded in soft soil.

[0008] The outer end of the telescopic body is provided with a stable end.

[0009] The bottom of the stabilizing rod is provided with a press-in end.

[0010] A connecting female terminal and a connecting sub-terminal are respectively provided on both sides of the panel frame.

Several panel frames can be formed into a whole through the chimeric connection between the connecting female terminal and the connecting sub-terminal.

[0011] The panel and the panel frame are detachably fixedly connected, and an elastic pad is provided at the contact position between the two.

[0012] Heightening plates are arranged around the panel frame, and the heightening plates are higher than the panel frame.

[0013] An application method of the self-stabilizing temporary channel paving device in soft soil areas is provided, wherein the application method comprises the following steps:

[0014] Calculate the number of temporary channel paving devices according to the paving size of the temporary channel;

[0027] The features of the present invention and other related features are further described in detail below through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

[0028] like Figure 1-5 As shown in the figure, marks 1-16 respectively represent: panel frame 1, sewage chamber 2, stabilizing rod 3, inflation tube 4, press-in terminal 5, vent 6, telescopic body 7, stabilizing terminal 8, panel 9, handle 10, elastic pad 11, sealing ring 12, inflatable rubber ring 13, raising plate 14, connecting female terminal 15, and connecting sub-terminal 16.

[0029] Embodiment: In this embodiment, the self-stabilizing temporary channel paving device in the soft soil area can be built in the soft soil area to form a temporary channel to meet the needs of various engineering construction operations.

[0030] like Figure 1 and Figure 2 As shown, the main body of the self-stabilizing temporary channel paving device in this embodiment includes a panel frame 1, a sewage chamber 2 and a stabilizing rod 3. Among them, the panel frame 1 is the main working layer of the device, which is installed above the sewage chamber 2. The interior of the sewage chamber 2 is a cavity, and the cavity is used to receive waste generated during use. At the same time, when the frame body of the sewage chamber 2 is placed in a soft soil area, it can remove the soft soil around the cavity, thereby making full use of the buoyancy generated by the soft soil and increasing the bearing capacity of the temporary channel paving device. The stabilizing rod 3 is installed on the panel frame 1. It can be set as an integral structure connected to the panel frame 1, or it can be set as a detachable connection structure with the panel frame 1. The stabilizing rod 3 is used to penetrate deep into the stratum of the soft soil area. It can limit the plane displacement of the temporary channel paving device, enhance stability, and further improve its bearing capacity.

[0031] like Figure 2As shown, the bottom of the stabilizing rod 3 is provided with a press-in end 5, which tapers upward from the bottom to facilitate the embedding of the stabilizing rod 3 into soft soil. A telescopic body 7 is provided at the bottom of the stabilizing rod 3. This telescopic body 7 can be extended and retracted horizontally, and a stabilizing end 8 is provided at the outer end of the telescopic body 7. An inflation tube 4 is provided inside the stabilizing rod 3 and is connected to the telescopic body 7. This inflation tube 4 allows the telescopic body 7 to extend outward (into the soft soil formation) and embed into the ground under the action of the inflation tube 4. The top end of the inflation tube 4 can be exposed on the surface of the panel frame 1, and an inflation rubber ring 13 is provided at the inflation port, and a sealing ring 12 is provided at the inflation rubber ring 13.

[0032] like Figures 3 and 4 As shown in the changes, when the stabilizing rod 3 is pressed into the appropriate position, the sealing ring 12 on the panel frame 1 can be opened, and the rated gas can be injected into the inflation tube 4 through the inflatable rubber ring 13. The gas expands the telescopic body 7 through the air vent 6, prompting the stabilizing end 8 to be horizontally embedded in the stratum in the soft soil area; at this time, the telescopic body 7 extended in the horizontal direction can limit the plane displacement of the temporary channel paving device to avoid its displacement during use, thereby ensuring stability. At the same time, since the telescopic body 7 is extended under the action of inflation and has a certain strength, the extended length range is supported in the stratum in the soft soil area, so it can also give the temporary channel paving device additional bearing capacity, further improving its bearing capacity.

[0033] like Figure 1 and Figure 2 As shown, the panel rack 1 is an array of frame structures, divided into several sections by a staggered vertical and horizontal structure. Each section can be equipped with a movable panel 9. Several panels 9 are combined to form the working surface of a temporary passage, where operators can perform various construction activities. A handle 10 is provided above the panel 9, allowing operators to freely move the panel 9 as needed. Elastic pads 11 are installed at the contact area between the panel 9 and the panel rack 1 to cushion the force of the device, protect the contact area between the panel 9 and the panel rack 1, and enhance user comfort.

[0034] In this embodiment, the handle 10 on the panel 9 can adopt an embedded structure and be flush with the panel 9. At the same time, the sealing ring 12 on the stabilizing rod 3 is flush with the panel 9 in the area, thereby ensuring that the working surface provided by the panel 9 is a flat surface to avoid usage obstacles caused by unevenness.

[0035] like Figure 2As shown, the panel frame 1 is surrounded by raised plates 14. These plates increase the volume of soft soil removed by the device, enhancing buoyancy and further increasing the device's load-bearing capacity. Specifically, when the panel frame 1 and the drainage chamber 2 are jointly pressed into the soft soil formation, the raised plates 14, which are higher than the surface of the panel frame 1, can be pressed relatively deeper, thereby removing a larger volume of soft soil and further enhancing buoyancy.

[0036] like Figure 2 and Figure 5 As shown, the temporary channel paving device in this embodiment adopts a unit body splicing structure, that is, Figure 1 The device shown is a unit, and multiple units can be assembled to form a temporary passage. A female connector 15 and a male connector 16 are provided at each end of the panel frame 1. Two panel frames 1 can be inserted horizontally in the same plane by inserting a female connector 15 and a male connector 16. The female connector 15 and the male connector 16 engage, restricting each other's vertical displacement, thereby enhancing the flatness of adjacent panel frames 1 and improving the passage paving effect.

[0037] In this embodiment, the connecting female terminal 15 and the connecting male terminal 16 adopt matching hook-shaped structures, so that the integrity between the panel frames 1 is improved.

[0038] In practical application, this embodiment includes the following steps:

[0039] 1) Preliminary assessment of the number of required laying device units based on the construction work requirements. Specifically, for example, the required length of the temporary access road can be used to calculate the required number of units.

[0040] 2) Place the panel racks 1 at the preset position of the temporary passage, and at the same time, insert the panel racks 1 into the connecting female terminals 15 and the connecting male terminals 16 and put them into place. This insertion is performed along the extension direction of the temporary passage.

[0041] 3) Press the panel frame 1 and stabilizing rods 3 into the ground. Depending on the load-bearing capacity, heightening plates 14 may be placed around the panel frame 1. For a structure where stabilizing rods 3 can move freely up and down within the panel frame 1 and the drainage chamber 2, i.e., the stabilizing rods 3 are detachably connected to the panel frame 1, the panel frame 1 can be placed first, followed by the stabilizing rods 3.

[0042] 4) Open the sealing ring 12 and pressurize a certain amount of gas into the inflatable rubber ring 13. The gas enters the telescopic body 7 through the vent 6, and the telescopic body 7 extends and expands in the soft soil stratum and embeds therein.

[0043] 5) The extension of the telescopic body 7 is judged according to the inflation volume and inflation pressure. When the stable end 8 stably enters the soft soil formation from the horizontal direction, the sealing ring 12 is covered.

[0044] 6) Place the panel 10 on the panel rack 1 using the handles.

[0045] 7) Repeat step 6) to complete the temporary channel laying.

[0046] 8) After the temporary passage is used, the sealing ring 12 is opened to release the gas, and the telescopic body 7 is retracted and closed.

[0047] The removable panels 9 installed on the panel rack 1 can expand the device's application range by adjusting the position and number of panels 9. For example, when conducting survey work on a temporary passage, the corresponding panel 9 can be lifted using the handle 10 to directly survey the soft soil below. Another example: when moving construction equipment on the temporary passage, the panel rack 1 can be fully covered with panels 9.

[0048] In the specific implementation of this embodiment: Figure 2 As shown, in this embodiment, two telescopic bodies 7 with opposite telescopic directions are arranged below the stabilizing rod 3. In order to further improve its limiting effect and the effect of improving the bearing capacity, a number of telescopic bodies that can extend in other directions can be further provided below the stabilizing rod 3. For example, four telescopic bodies are evenly and symmetrically arranged below the stabilizing rod 3, and the telescopic bodies are arranged at right angles to each other.

[0049] like Figure 1 As shown, in addition to providing the female connector 15 and the male connector 16 on both sides of the panel frame 1, a connecting structure can also be provided on the other two sides of the panel frame 1, so that the panel frame 1 can expand its coverage as needed, that is, expand the width of the temporary channel formed by the panel frame 1, thereby further expanding its application range. In the embodiment, the connecting structure can adopt the female connector 15 and the male connector 16 of this embodiment, or other connecting structures that achieve a chimeric connection can be adopted.

[0050] The stabilizing rod 3 can be provided with a telescopic structure to cope with the stabilizing needs of different depths. The telescopic structure can adopt a structure such as a set telescopic joint, a spliced segment, etc.

[0051] The main components of this embodiment, including the panel 9, panel frame 1, male connector 16, female connector 15, stabilizing rod 3, and heightened plate 14, can be made of lightweight, rigid, and strong materials. Depending on available materials, the panel 9 can also be made of conventional compression-resistant materials such as formwork or bamboo boards. The telescopic body 7 can be made of a material with strong resilience, minimal fatigue damage, resistance to puncture by sharp objects, and high stability.

[0052] Although the above embodiments have described in detail the concepts and embodiments of the present invention with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, so they are not described in detail here.
