Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a horizontal fixed-point core filling device for underground obstacle removal construction. Background Art

[0002] With the deepening of urbanization, the ground space in large-scale urban core areas is becoming increasingly crowded, and the development and construction of underground space has become a hot spot in the new round of infrastructure. However, urban underground space construction often produces a large number of complex underground structural obstacles due to inadequate early planning and historical problems, which hinder the construction process of underground space. The various technical difficulties in underground space construction brought about by this are placed in front of current engineering builders. For example, when a new subway line passes through an existing subway station, it is necessary to clear the underground partial reinforced concrete structure of the existing station before the shield machine passes through the underground structure of the existing subway station. During the clearance process, in order to prevent the exposed soil layer after fixed-point clearance from collapsing through the clearance hole and causing harm, an underground fixed-point core block backfilling technology is needed to ensure the safety of the existing structure around the clearance operation.

[0041] Embodiment 6:

[0042] This embodiment is a fixed-point core filling device for special easy-collapse geological conditions. Under easy-collapse geological conditions, the above-mentioned embodiment is adopted. If collapse or landslide occurs in the core filling hole on the wall 52 during core filling, the core filling block 5 cannot be pushed into the core filling hole on the wall, and the core filling construction will be affected. In view of this situation, the product of this embodiment is developed. The difference from the above-mentioned embodiment is that;

[0043] like Figure 6-7As shown, a horizontal fixed-point core filling device for underground obstacle removal construction, a pulley support 10 is fixedly installed on the outer frame 1, a pulley device fixing frame 9 is correspondingly installed on the pulley support 10, a pulley 8 is fixed on the pulley device fixing frame 9, a grouting hose 7 is arranged between the pulley device fixing frame 9 and the pulley 8, the pulley support 10 and the corresponding pulley device fixing frame 9 and the pulley 8 are each provided with two groups, a grouting channel 51 is arranged inside the push plate 6 and the core filling block 5, the grouting hose 7 is connected with the grouting channel 51 through the pulley 8, a trapezoidal protrusion is arranged at the front end of the push plate 6, a corresponding recess is arranged at the end of the core filling block 5 that contacts the push plate 6, and the cross-section of the core filling block 5 is a trapezoidal structure. In this embodiment, the grouting hose 7 is arranged between the pulley device fixing frame 9 and the pulley 8, so that the grouting hose 7 can be fixed without displacement on the one hand, and on the other hand, the grouting hose 7 is not easily damaged by other component structures. In addition, the setting of the pulley 8 allows the grouting hose 7 to be telescopic and slidable, and the position setting of the two sets of pulleys 8 allows the grouting hose 7 to maintain a certain curvature and is not prone to blockage. In addition, the front end protrusion of the push plate 6 is adapted to the recessed portion of the core filling block 5, and the grouting hose 7 extends into the front end of the core filling block 5 through the grouting channel 51, which facilitates the grouting operation.

[0044] The outer frame 1 described in the above embodiment is composed of a square steel structure welded together. A back plate is provided at the rear end of the outer frame 1 and is welded and fixed to the frame as a reaction back plate 13. The fixed installation method in the above embodiments is preferably welded, which has the lowest cost and the highest economic value. The outer frame 1 in the above embodiment serves as the external protection and force-bearing structure of the core filling device, mainly as a force-bearing skeleton for the internal hydraulic cylinder to push and pull, effectively enhancing the overall force stability of the core filling device, while protecting the internal hydraulic cylinder, push bucket and other devices; the outer frame 1 also serves as a vertical track positioning frame for the core filling device when it goes up and down in the temporary working shaft for obstacle clearance, effectively ensuring the positioning accuracy of the core block backfilling operation.

[0045] Working principle: The horizontal fixed-point core filling device is hoisted to the predetermined core block backfilling position through the temporary working shaft in the underground obstacle clearance construction. Before hoisting, the backfill core block 5 is preset in the push barrel 3. During hoisting, the outer frame 1 is in the vertical track prefabricated in the temporary working shaft to ensure accurate horizontal positioning. After the device is hoisted into place, the ground operator operates the hydraulic system to control the hydraulic pushing device 2 to push the push barrel 3 out of the predetermined stroke along the slide rail support 4 horizontally, and then operates the hydraulic system to control the push rod A24 in the push barrel 3 to push, and the preset core filling block 5 is pushed out of the push barrel 3 to the predetermined core filling hole position through the push plate 6. After the core filling block 5 is in place, the push barrel 3 is pulled back to its position, and then the push rod A24 is pulled back to its position. After the action is in place, the horizontal fixed-point core filling device is hoisted along the vertical track in the temporary working shaft to the ground for the next use. The hydraulic jacking device 2 can effectively provide the pushing and retracting power of the push barrel 3 and the push plate 6, ensuring that the core-filling block 5 is backfilled in place and the push barrel 3 is retracted in place. The slide rail support 4 arranged below the push barrel 3 effectively supports the push-pull action of the push barrel 3 in the vertical direction, and enables the push barrel 3 to move horizontally along the track, ensuring the accuracy of the device's pushing and retracting action and the backfilling position of the core-filling block 5. Embodiments 1 to 5 of the utility model are aimed at the situation where the geological conditions are relatively good. In this case, the core-filling block 5 is basically adapted to the core-filling hole, and a relatively good core-filling operation can be performed on the core-filling hole. Embodiment 6 is aimed at the situation where the geological conditions are not good. In this case, the core-filling block 5 blocks the opening of the core-filling hole, and the grouting hose performs grouting operations on the cavity part in the core-filling hole, so that the core-filling operation can be carried out smoothly.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
