Technical Field

[0001] The invention relates to the technical field of pipe jacking construction, and in particular to an adjustable base structure and an adjustment method for pipe jacking construction. Background Art

[0002] Pipe jacking is an underground trenchless construction method, which is widely used in underground pipelines, power cable underground pipelines, rainwater and sewage diversion underground pipelines, and underground integrated pipe corridors. Pipe jacking is to use the jacking force generated by the jacking equipment in the working well to push the jacking pipe section by section into the established track, and then penetrate the entire channel through continuous jacking.

[0003] During the pipe jacking construction process, a base needs to be installed to support the construction work. However, the height difference between the position of the soft eyes opened for the pipe jacking in different working wells and the ground of the working well is different, which causes the base work to be constantly adjusted and the steel structure in the base of the pipe jacking equipment to be constantly welded and cut, which is extremely inconvenient for on-site construction work.

[0004] The following problems often occur during the construction process: (1) The height difference between the soft eye and the ground of the working pit is not equal in different working pits; (2) After the installation of the jacking equipment base, it is not completely vertical with the soft eye; (3) After the installation of the jacking equipment base, there is not enough space left for the jacking materials.

[0040] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] The present application relates to an adjustable base structure for pipe jacking construction. The base structure of the present application is used to support the pipe jacking, and by adjusting the position, flatness and height of the pipe jacking, the pipe jacking is docked with the soft eye to be jacked, so that the pipe jacking can be accurately docked with the soft eye, which is convenient for subsequent jacking construction. The base structure of the present application is very simple and easy to operate. It is very easy to adjust the position, flatness and height of the pipe jacking, which improves the efficiency of pipe jacking construction. The base structure of the present application is reusable, saving a lot of manpower and material costs.

[0042] Specifically, Figures 1 to 3 As shown, an adjustable base structure for pipe jacking construction of the present application comprises a support plate 1, a support groove 2 and a bottom plate 4, wherein the support plate 1 is the main structure of the entire base structure, the support groove 2 is a plate-like structure with an arc-shaped groove for placing the pipe jacking at the upper end, the support groove 2 is fixed on the support plate 1, the support groove 2 is a support structure directly in contact with the pipe jacking, and the arc-shaped groove provided on the support groove 2 is a groove-like structure for facilitating the placement of the pipe jacking, and after the pipe jacking is placed in the arc-shaped groove, the pipe jacking is fixedly connected to the support groove 2 in the non-axial direction. The support groove 2 is fixedly connected to the support plate 1, and multiple groups of fixed rod structures are arranged between the support groove 2 and the support plate 1, and the multiple groups of fixed rod structures are arranged at equal intervals along the axial direction of the support groove 2 (i.e., the axial direction of the arc-shaped groove, or the axial direction of the pipe jacking placed in the arc-shaped groove), and the fixed rod structure comprises a fixed seat fixed on the upper end surface of the support plate 1 and a fixed rod installed on the fixed seat, the lower end of the fixed rod is fixedly connected to the fixed seat, and the upper end is fixedly connected to the lower end surface of the support groove 2. In actual application, multiple groups of support grooves 2 can be set on the support plate 1, and adjacent support grooves 2 are arranged in sequence along the axial direction. Each support groove 2 corresponds to a number of fixed rod structures. In actual application, an appropriate number of support grooves 2 can be selected according to the specifications of the jacking pipe to be constructed. The longer the jacking pipe, the more corresponding support grooves 2 there are, and vice versa. Multiple installation interfaces corresponding to the fixed seat are set on the support plate 1 along the axial direction, and the interface corresponding to the fixed rod is set on the lower end surface of the support groove 2. When in use, the assembly of the support groove 2 and the support plate 1 can be completed by installing the fixed seat, the fixed rod and the support groove 2 through the corresponding interface. The interface of the present application can be a card slot set on the support plate 1 and the support groove 2, and a protrusion set on the fixed seat and the fixed rod. When installing, the protrusion is snapped into the corresponding card slot to complete the corresponding connection.

[0043] The bottom plate 4 is a plate-like structure located below the support plate 1. An adjustment structure for adjusting two sets of vertical spacing is provided between the bottom plate 4 and the support plate 1. The vertical height between the bottom plate 4 and the support plate 1 can be adjusted by the adjustment structure. By adjusting the heights of the support plate 1 and the bottom plate 4 at different positions, the inclination of the support plate 1 can be changed, thereby achieving the purpose of leveling the top pipe. After completing the leveling operation of the support plate 1, the spacing of the support plate 1 relative to the bottom plate 4 can be adjusted by the adjustment structure as a whole, so that the height of the support plate 1 and the top pipe thereon can be adjusted.

[0044] In actual use, after the base structure is assembled, it is moved into the working pit, and the base structure is roughly adjusted so that the support groove 2 on the base structure is roughly aligned with the soft eye; the jacking pipe is hoisted onto the support groove 2, so that the jacking pipe is fixed in the support groove 2, and then the position of the base structure is adjusted so that the jacking pipe is aligned with the soft eye in the axial direction, and then the flatness and height of the jacking pipe are adjusted so that the jacking pipe and the soft eye are completely aligned;

[0045] For adjusting the flatness of the top pipe, the adjustment structure of the tilting direction of the support plate 1 is adjusted to make the support plate 1 leveled to meet the requirements, thereby completing the operation of leveling the top pipe; for adjusting the height of the top pipe, all adjustment structures are adjusted to a uniform height until the top pipe and the soft eye are accurately aligned in the axial direction.

[0046] In some embodiments of the present application, the present embodiment optimizes the above-mentioned adjustment structure, specifically, Figures 1 to 3 As shown, the adjustment structure of this embodiment includes multiple groups of telescopic legs with adjustable vertical heights disposed between the bottom plate 4 and the support plate 1, and the multiple groups of telescopic legs are spaced apart along the first horizontal direction or the second horizontal direction of the support plate 1, and the first horizontal direction and the second horizontal direction are perpendicular to each other. Figure 3 As shown, the horizontal first direction of this embodiment is Figure 3 The left and right directions in the embodiment are as follows: Figure 3 The direction perpendicular to the paper surface. In this embodiment, multiple telescopic legs 3 are arranged between the bottom plate 4 and the support plate 1. By adjusting the extension length of the telescopic legs 3 at different positions, the support plate 1 can be leveled and the height adjusted. For example, if one side of the support plate 1 is low and the other side is high, the telescopic legs 3 on the low side can be extended and adjusted to raise the support plate on the low side to achieve leveling, or the telescopic legs 3 on the high side can be retracted and adjusted to lower the support plate on the high side, which can also achieve the leveling operation. By adjusting all the telescopic legs 3 synchronously, the height adjustment of the support plate 1 can be achieved.

[0047] Specifically, the telescopic legs 3 of the present embodiment include two movable plates, the upper and lower ends of which are slidably connected to the support plate 1 and the bottom plate 4, respectively, and the center positions of the two movable plates in the same group are hingedly connected to rotate around the horizontal axis to form a scissor brace structure. In fact, the telescopic legs 3 of the present embodiment are scissor brace structures, and guide grooves can be provided on the bottom plate 4 and the support plate 1, and the upper and lower ends of the movable plates are respectively located in the guide grooves on the support plate 1 and the bottom plate 4. When adjusting the telescopic legs 3, it is actually to adjust the hinge angles of the two movable plates, so that the upper and lower ends of the movable plates slide in the guide grooves, and the vertical spacing between the support plate 1 and the bottom plate 4 is changed.

[0048] The telescopic legs 3 of this embodiment can be vertically adjusted in the range of 30 cm to 150 cm.

[0049] like Figures 1 to 3 As shown, in this embodiment, two groups of telescopic legs 3 are arranged between the bottom plate 4 and the support plate 1. The two groups of telescopic legs 3 are spaced apart on both sides of the bottom plate 4 along the second horizontal direction, and each group of telescopic legs 3 has four contact points with the bottom plate 4 and the support plate 1. When the support plate 1 needs to be leveled, the leveling effect can be achieved by adjusting one of the two groups of telescopic legs 3. When the height of the support plate 1 needs to be adjusted as a whole, the two groups of telescopic legs 3 are adjusted synchronously as a whole to achieve the effect of height adjustment.

[0050] For the adjustment of the telescopic leg 3, a corresponding driving structure can be installed on the support plate 1 or the base plate 4, such as a screw structure installed on the support plate 1 or the base plate 4, the screw structure is connected to the ends of two movable plates of the same group on the support plate 1 or the base plate 4, and the purpose of adjusting the hinge angle of the two movable plates of the telescopic leg 3 can be achieved by adjusting the distance between the ends of the two movable plates through the screw structure.

[0051] In addition, in order to facilitate the movement of the entire base structure, the present embodiment is provided with a pulley 6 on the lower end surface of the bottom plate 4. It is convenient for the operator to push the base structure to move in the working pit and adjust the horizontal position of the top pipe. The present embodiment is also provided with a brake 7 on the pulley 6 to facilitate the fixing of the pulley 6. After the position of the base structure is adjusted, the brake 7 can be used to fix the entire base structure.

[0052] In other embodiments of the present application, the present embodiment further defines the structure of the bottom plate 4, such as Figure 1 and 3As shown, in this embodiment, a fixing structure for fixing the telescopic legs 3 to the ground is provided on the bottom plate 4. The brake 7 mentioned above is used to fix the pulley 6 and is provided to limit the rotation of the pulley 6. After the brake 7 is used, the pulley 6 no longer rotates, and the pulley 6 is fixed and limited by the friction force of the pulley 6. However, this limiting effect is relatively limited and cannot completely fix and limit the base structure. Therefore, this embodiment provides another set of fixing structures.

[0053] The fixing structure comprises a positioning bolt 5, which is vertically adjustable and penetrates the bottom plate 4. The lower end of the positioning bolt 5 is a sharp end that can be inserted into the ground soil layer.

[0054] In actual use, after the base structure is adjusted to the right position, the positioning bolts 5 are screwed to extend the positioning bolts 5 downward until the sharp part of the lower end of the positioning bolts 5 is inserted into the ground layer, and the bottom plate 4 is fixed in position. After all the positioning bolts 5 are inserted into the soil layer, the base structure can be well fixed in position. At this time, the fixing of the base structure is no longer based on the friction force of the pulley 6, but the positioning bolts 5 are extended into the soil layer to anchor the base structure in the current position.

[0055] During actual construction, the base structure is assembled and moved into the working pit, the base structure is roughly adjusted, and the base structure is horizontally moved by the pulley 6 so that the support groove 2 on the base structure is roughly aligned with the soft eye; the jacking pipe is hoisted onto the support groove 2, so that the jacking pipe is fixed in the support groove 2, and then the position of the base structure is adjusted by the pulley so that the jacking pipe is aligned with the soft eye in the axial direction, and the pulley 6 is locked by the brake 7, and then the flatness and height of the jacking pipe are adjusted; for the adjustment of the flatness of the jacking pipe, the telescopic legs 3 in the inclination direction of the support plate 1 are adjusted to change the extension length of the current telescopic legs 3, so that the support plate 1 is leveled to meet the requirements, and the operation of leveling the jacking pipe is completed; for the adjustment of the height of the jacking pipe, all the telescopic legs 3 are adjusted to a uniform height until the jacking pipe is accurately aligned with the soft eye in the axial direction; all the positioning bolts 5 are screwed so that the lower ends of the positioning bolts 5 are inserted into the ground soil layer, and the base structure is anchored in the current position, completing the fixation of the base structure and the jacking pipe.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present application.
