Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking construction, in particular to a pipe jacking construction adjustable height difference base structure. Background Art

[0002] Pipe jacking is a trenchless underground construction method widely used in underground pipelines, power cable pipelines, rainwater and sewage separation pipelines, and underground integrated pipeline corridors. Pipe jacking involves using the jacking force generated by pipe jacking equipment in a working pit to push the jacking pipe section by section into the predetermined track. Through continuous jacking, the entire channel is connected.

[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 shafts and the ground of the working shaft is different, which causes the base 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 well is not the same in different working wells; (2) After the installation of the jacking equipment base, it is not completely perpendicular to the soft eye position; (3) After the installation of the jacking equipment base, there is not enough space left for the jacking materials.

[0038] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] The present application relates to a base structure with adjustable height difference 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, facilitating subsequent jacking construction. The base structure of the present application is very simple and extremely convenient to operate and use. It is extremely easy to adjust the position, flatness and height of the pipe jacking, thereby improving the efficiency of the pipe jacking construction. The base structure of the present application is reusable, saving a lot of manpower and material costs.

[0040] Specifically, such as Figures 1 to 3As shown, the present invention discloses a base structure with adjustable height difference for pipe jacking construction, comprising a support plate 1, a support groove 2 and at least two sets of telescopic legs 3. 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 at the upper end for placing the pipe jacking. The support groove 2 is fixed to the support plate 1. The support groove 2 is a support structure that directly contacts the pipe jacking. The arc-shaped groove provided on the support groove 2 is a groove-like structure for facilitating the placement of the pipe jacking. 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. A plurality of fixing rod structures are provided between the support groove 2 and the support plate 1. The plurality of fixing rod structures are equidistantly spaced 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). The fixing rod structure comprises a fixing seat fixed to the upper end surface of the support plate 1 and a fixing rod mounted on the fixing seat. The lower end of the fixing rod is fixedly connected to the fixing 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, the 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 mounting interfaces corresponding to the fixed seat are set on the support plate 1 along the axial direction, and the lower end surface of the support groove 2 is provided with an interface corresponding to the fixed rod. When in use, the fixed seat, the fixed rod and the support groove 2 are installed through the corresponding interface to complete the assembly of the support groove 2 and the support plate 1. 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.

[0041] Telescopic legs 3 are vertically adjustable columnar structures connected to support plate 1 at their upper ends. Each set includes two legs symmetrically arranged about the centerline of support plate 1, with adjacent sets of telescopic legs 3 spaced axially apart. The telescopic legs 3 are vertically adjustable; by adjusting the telescopic length of the legs 3, the flatness and height of the jacking pipe can be adjusted.

[0042] During actual use, after assembling the base structure, move it into the working pit and make a rough adjustment on the base structure so that the support groove 2 on the base structure is roughly aligned with the soft eye; hoist the jacking pipe onto the support groove 2 and fix it in the support groove 2, then adjust the position of the base structure so that the jacking pipe is aligned with the soft eye in the axial direction, and then adjust the flatness and height of the jacking pipe so that the jacking pipe and the soft eye are completely aligned;

[0043] For the adjustment of the pipe jacking flatness, the telescopic legs 3 in the inclination direction of the support plate 1 are adjusted to make the support plate 1 level to the requirements, and the operation of adjusting the pipe jacking is completed; for the adjustment of the pipe jacking height, the telescopic legs 3 are uniformly adjusted to the height until the pipe jacking and the soft eye are accurately aligned in the axial direction.

[0044] In some embodiments of the present application, the telescopic leg 3 structure described above is optimized, and specifically, as shown in Figures 1 to 3 The telescopic leg 3 of the embodiment includes a fixed part, a telescopic part, and an adjusting block 4. The fixed part is a columnar structure connected to the lower end of the support plate 1, and the lower end extends vertically. The upper end of the telescopic part is telescopically movable and is sleeved on the lower end of the fixed part. The adjusting block 4 is at the connection between the fixed part and the telescopic part, and the adjusting block 4 is provided with an adjusting bolt 5 for adjusting the telescopic length of the telescopic part.

[0045] The fixed part can be a cylindrical structure, and the upper end of the telescopic part is telescopically movable and is sleeved on the lower end of the fixed part. Alternatively, the adjusting block 4 has a space reserved for the telescopic part to move up and down, as long as the telescopic part can move vertically relative to the fixed part. The telescopic part of the embodiment can move vertically relative to the fixed part within a range of 30 cm to 150 cm.

[0046] The adjusting block 4 can use a gear drive structure or a lead screw transmission structure to drive the telescopic part. For example, a gear structure is arranged in the adjusting block 4, a rack structure is arranged on the telescopic part, the gear structure and the rack structure are in transmission connection, the gear structure is fixedly connected with the adjusting bolt 5 passing through the adjusting block 4, the gear structure is driven to rotate around the axis by screwing the adjusting bolt 5, thereby driving the rack structure to move vertically relative to the gear structure, and the telescopic movement of the telescopic part is realized. In actual application, the driving structure is not limited to the gear and rack structure, and other forms of driving structure can also be used as long as the telescopic part can move vertically.

[0047] In addition, in order to facilitate the movement of the entire base structure, the embodiment is provided with a pulley 6 at the lower end of the telescopic leg 3. The operator can push the base structure to move in the working well, and adjust the horizontal position of the pipe jacking. The embodiment is also provided with a brake 7 on the pulley 6, which facilitates the fixation of the pulley 6. After the position of the base structure is adjusted, the entire base structure can be fixed and limited by the brake 7.

[0048] In some embodiments of the present application, the telescopic leg 3 structure described above is optimized, and specifically, as shown in Figure 1 and 3As shown, this embodiment is provided with a fixing structure on the telescopic leg 3 for fixing the telescopic leg 3 to the ground. The brake 7 mentioned above is used to fix the pulley 6 and is provided to limit the rotation of the pulley 6. When the brake 7 is applied, the pulley 6 stops rotating and the friction force of the pulley 6 is used to fix the pulley 6 in position. However, this limiting effect is relatively limited and cannot completely fix the base structure. Therefore, this embodiment provides an additional set of fixing structures.

[0049] The fixing structure includes a mounting plate 8 and a positioning bolt 9. One end of the mounting plate 8 is fixed to the telescopic portion of the telescopic leg 3, and the other end extends horizontally beyond the telescopic portion. The positioning bolt 9 is vertically adjustable and extends through the portion of the mounting plate 8 extending from the telescopic portion. The lower end of the positioning bolt 9 has a sharp end that can be inserted into the ground.

[0050] In actual use, after the base structure is adjusted into position, the positioning bolts 9 are tightened to extend the positioning bolts 9 downward until the sharp end of the positioning bolts 9 is inserted into the ground layer, thereby fixing the corresponding telescopic legs 3. After all the telescopic legs 3 are positioned and fixed, 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 on the positioning bolts 9 extending into the ground layer to anchor the base structure in its current position.

[0051] In a further embodiment of the present application, this embodiment further optimizes the structure of the telescopic legs 3 on the lower end surface of the above-mentioned support plate 1. Specifically, this embodiment is provided with at least three groups of telescopic legs 3 on the lower end surface of the support plate 1, including two groups of telescopic legs 3 located at both ends of the support plate 1 and a group of telescopic legs 3 located in the middle position of the support plate 1.

[0052] like Figures 1 to 3 As shown, the lower end surface of the support plate 1 of this embodiment is provided with three groups of telescopic legs 3, and the three groups of telescopic legs 3 are arranged at equal intervals in the axial direction, including two groups of telescopic legs 3 located at both ends of the support plate 1 and a group of telescopic legs 3 located in the middle position of the support plate 1. Each group includes two groups of telescopic legs 3 located at both ends of the support plate 1 and a group of telescopic legs 3 located in the middle position of the support plate 1, that is, six telescopic legs 3 are provided on the lower end surface of the support plate 1.

[0053] 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, 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 tilt direction of the support plate 1 are adjusted, and the adjusting bolts 5 on the telescopic legs 3 are screwed 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 uniformly adjusted in height until the jacking pipe is accurately aligned with the soft eye in the axial direction; all the positioning bolts 9 are screwed so that the lower ends of the positioning bolts 9 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.
