Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel excavation, and in particular relates to a multifunctional grouting trolley for a segment tunnel. Background Art

[0002] With the continuous increase of tunnel projects at home and abroad, shield machines and TBMs have been used more and more widely as powerful tools for tunnel construction. During the excavation process, shield machines and TBMs often need to use precast concrete segments to synchronously support the excavated tunnels. The annular gap between the outer wall of the segment and the surrounding rock wall needs to be filled with cement slurry to ensure that the segment and the surrounding rock wall form a stable and reliable support body.

[0003] While tunneling, shield machines and TBMs use the grouting system installed on the equipment to synchronously grout the annular gaps behind the segment walls, thereby achieving initial stability of the segment support body. When the slurry of synchronous grouting is completely solidified, the support strength of the segment support body is improved, but gaps or cavities may be generated in the annular cavity behind the segment wall due to slurry solidification shrinkage or uneven grouting, thereby affecting the support and waterproofing effect of the segment tunnel. Therefore, segment tunnels excavated by shield machines and TBMs often require secondary grouting behind the segment wall to fill the gaps or cavities behind the segment wall, thereby improving the density and firmness of the segment support body.

[0004] Conventional grouting operations require the use of a series of independent equipment (drilling equipment, slurry making equipment, slurry supply equipment, grouting equipment, etc.), and a series of complicated manual operations to achieve secondary grouting behind the segment wall. This conventional grouting operation has a low degree of integration and automation, a large number of operators and high labor intensity, and requires a large amount of operating and passage space in the tunnel, which seriously affects the normal transportation of tunnel construction materials and personnel, thereby reducing the excavation efficiency of shield machines and TBMs. Utility Model Content

[0005] The purpose of the utility model is to provide a multifunctional grouting trolley for a segment tunnel, which integrates automated drilling equipment, high-speed automated slurry making equipment, automatic slurry storage and mixing equipment, automatic grouting equipment, and corresponding auxiliary power supply equipment, and can realize automated and standardized control of grouting behind the tunnel segment wall, thereby greatly reducing the labor intensity of personnel and also improving the grouting quality behind the segment wall.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is to design a multifunctional grouting trolley for a segment tunnel, including a driving platform, a driving wheel group, an equipment platform and functional equipment; a driving track is laid at the bottom of the tunnel of the segment tunnel; a plurality of driving wheel groups are arranged at the bottom of the driving platform, and the driving wheel groups move on the driving track at the bottom of the tunnel; equipment platforms are arranged on the left and right sides of the driving platform, and functional equipment is placed on the equipment platforms; a driving track for tunnel construction material trains to pass is arranged in the central area of ​​the upper surface of the driving platform.

[0007] Furthermore, the functional equipment includes drilling equipment, auxiliary power equipment, grouting equipment, slurry storage equipment and slurry making equipment.

[0008] Furthermore, the front and rear ends of the driving platform are respectively provided with slope sections, and the lower part of the slope section is provided with several groups of driving wheel groups that can move on the driving track at the bottom of the tunnel; the upper surface of the slope section is provided with a driving track for tunnel construction material trains to pass.

[0009] Furthermore, the driving track available for tunnel construction material trains and the driving track at the bottom of the tunnel use the same track model and track gauge, and the driving track available for tunnel construction material trains and the driving track at the bottom of the tunnel are on the same vertical plane.

[0010] Furthermore, a crane driving mechanism is provided at least at one end of the front and rear ends of the crane platform, and the crane driving mechanism is composed of a jacking cylinder, a hydraulic power station and a track clamp; one end of the jacking cylinder is connected to the track clamp, and the other end of the jacking cylinder is connected to the crane platform; the hydraulic power station drives the track clamp to clamp or loosen the crane track at the bottom of the tunnel.

[0011] The advantages and beneficial effects of the utility model are:

[0012] 1) The utility model is a highly integrated segment wall back grouting equipment, which can realize the automation and standardized control of grouting operation, thereby greatly reducing the labor intensity of personnel, and also improving the grouting quality behind the segment wall.

[0013] 2) When the utility model is in construction, the normal passage of tunnel construction materials and personnel can still be met, and the grouting behind the segment wall does not interfere with the tunneling of the shield machine / TBM, thereby improving the tunneling efficiency of the shield machine / TBM.

[0014] 3) The utility model has a self-propelled function, so the grouting operation behind the segment wall can be carried out at any position along the tunnel, thus having strong application flexibility.

[0015] 4) The utility model has a parking brake function, so it can be used for construction work in tunnels with large slopes, thus having strong engineering adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Example

[0024] like Figure 1 to Figure 6 As shown, a multifunctional grouting trolley for a segment tunnel comprises a driving platform 1, a driving wheel group 9, an equipment platform 4 and a functional device B; a driving track 10 is laid at the bottom of the tunnel of the segment tunnel A; a plurality of driving wheel groups 9 are arranged at the bottom of the driving platform 1, and the driving wheel groups 9 move on the driving track 10 at the bottom of the tunnel; equipment platforms 4 are arranged on the left and right sides of the driving platform 1, and the functional device B is placed on the equipment platform 4; a driving track 10 for tunnel construction material trains to pass is arranged in the central area of ​​the upper surface of the driving platform 1.

[0025] Functional equipment B includes drilling equipment 3, auxiliary power equipment 5, grouting equipment 6, slurry storage equipment 7 and slurry making equipment 8.

[0026] like Figure 1 , Figure 3As shown, when the construction material train needs to pass the multifunctional grouting trolley, the front and rear ends of the driving platform 1 are respectively provided with a slope section 2, and a plurality of groups of driving wheel groups 9 that can move on the driving track 10 at the bottom of the tunnel are provided at the lower part of the slope section 2. A driving track 10 for the tunnel construction material train to pass is provided on the upper surface of the slope section 2; the driving track 10 for the tunnel construction material train to pass and the driving track 10 at the bottom of the tunnel use the same track model and gauge, and the driving track 10 for the tunnel construction material train to pass and the driving track 10 at the bottom of the tunnel are in the same vertical plane, ensuring that the construction material train can pass the multifunctional grouting trolley smoothly.

[0027] like Figure 2 , Figure 4 As shown, when the multifunctional grouting trolley needs to realize autonomous movement, the front and rear ends of the driving platform 1 are respectively provided with a driving mechanism, which is composed of a jacking cylinder 11, a hydraulic power station and a rail clamp 12. Figure 6 As shown, one end of the jacking cylinder 11 is connected to the rail clamp 12, and the other end of the jacking cylinder 11 is connected to the driving platform 1; the hydraulic power station drives the rail clamp 12 to clamp or loosen the driving track 10 at the bottom of the tunnel.

[0028] The clamping force of the rail clamp 12 is used to bear the reverse propulsion force of the multifunctional grouting trolley. When the rail clamp 12 clamps the traveling track 10 and the telescopic rod of the jacking oil cylinder 11 is extended, the multifunctional grouting trolley is pushed forward by the distance of the oil cylinder stroke. After that, the rail clamp 12 releases the traveling track 10, the telescopic rod of the jacking oil cylinder 11 retracts, and drives the rail clamp to move forward by the distance formed by the oil cylinder. The above process is repeated in this way to realize the autonomous walking of the multifunctional grouting trolley.

[0029] Since the rail clamps 12 and the jacking cylinders 11 are provided at both ends of the driving platform 1, the multifunctional grouting trolley can move forward and backward. When the multifunctional grouting trolley moves to the designated working position, the jacking cylinders 11 are in a stationary state, and the rail clamps 12 clamp the driving rails 10. At this time, the multifunctional grouting trolley has a parking brake function.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
