Description

Technical Field

[0001] This invention belongs to the field of foundation construction devices, and specifically relates to a foundation excavation construction equipment and excavation construction process. Background Technology

[0002] Building foundations are divided into natural foundations and artificial foundations. A natural foundation is a foundation that can directly bear the load of a building without any treatment. Conversely, an artificial foundation is a foundation that requires treatment using foundation treatment techniques. The foundation refers to the enlarged part of the walls or columns of a building that is based on the foundation and is buried underground. The design and testing of the foundation are important parts of the work of construction engineers.

[0003] When constructing a foundation, excavation is required to remove the loose soil from the ground until the hard loess is reached. Patent publication number CN112962707B discloses equipment and excavation construction technology for foundation excavation. This patent relates to the field of foundation excavation construction. The equipment for foundation excavation includes a construction frame, a lifting ring, a material box, a first lifting component, and a clamping component. The material box is detachably connected to the lifting ring. The clamping component includes a lifting seat, a bidirectional screw, a first motor, and two clamping rods. The first lifting component drives the lifting seat to move vertically. The bidirectional screw is rotatably connected to the lifting seat. The first motor drives the bidirectional screw to rotate. The threaded sections of the clamping rods and the bidirectional screw are threadedly connected. The clamping rods are slidably connected to the lifting seat. The foundation excavation construction technology includes the following steps: S1: drilling; S2: hole wall protection; S3: setting up the foundation excavation construction equipment; S4: placing the excavated soil into the material box; S5: transporting the material box to the road surface and emptying the soil from the material box. The patent has the effect of facilitating the transportation of soil to the road surface when the allowable construction area is small; however, in actual use, construction workers still need to enter the foundation pit and manually put the soil into the material box for delivery, resulting in poor construction efficiency and unsuitability for foundation pit operations with large areas.

A hydraulic press 2 is mounted on the upper end face of the support frame 1. The hydraulic press 2 is vertically connected to the upper end face of the support frame 1 through a support column 3. The end of the hydraulic rod 4 inside the hydraulic press 2 is connected to the upper end face of the collecting cylinder 5. The bottom face of the collecting cylinder 5 is connected to the drilling cylinder 6. The excavation device 7 is installed at the bottom of the drilling cylinder 6. A drive system 9 is installed on the outer wall of the drilling cylinder 6 to drive the excavation device 7 and the drilling cylinder 6 to rotate synchronously. A discharge box 10 is connected to the side of the collecting cylinder 5. A conveyor plate 8 is installed below the discharge box 10. The conveyor plate 8 is installed at the bottom of the support frame 1. A soil and rock conveyor belt is installed inside the conveyor plate 8. When the device is working, the support frame 1 is erected at the upper edge of the foundation pit, and the conveyor plate 8 is placed at the bottom of the support frame 1 and the ground at the outer edge of the foundation pit. The drive system 9 drives the digging device 7 and the drilling cylinder 6 to rotate, and the hydraulic press 2 drives the digging device 7 and the drilling cylinder 6 to move downward. The soil and rocks excavated by the digging device 7 pass through the drilling cylinder 6 and are transported to the collection cylinder 5. Finally, they are discharged from the discharge box 10 and fall onto the conveyor plate 8, and are transported to the designated position by the conveyor plate 8.

[0016] Preferred solutions include Figure 2 As shown, a guide plate 101 is vertically arranged on the side of the support frame 1, and a guide groove 102 is provided on the guide plate 101. A clamping plate 601 is vertically connected to the outer wall of the drilling barrel 6, and the other end of the clamping plate 601 is clamped in the guide groove 102. Since the guide groove 102 is vertically arranged with the ground, this design enables the clamping plate 601 and the drilling barrel 6 to slide vertically up and down, and improves the stability during sliding.

[0017] Preferred solutions include Figure 1 and Figure 3As shown, the drilling cylinder 6 includes a fixed upper cylinder 602 and a movable lower cylinder 603. The upper end of the fixed upper cylinder 602 is vertically connected to the bottom of the discharge box 10. The upper end face of the movable lower cylinder 603 is connected to the fixed upper cylinder 602 through a movable joint 604. The movable lower cylinder 603 is coaxially arranged with the fixed upper cylinder 602 and can rotate freely around the axis. A drive system 9 is installed at the bottom of the fixed upper cylinder 602. The drive system 9 drives the movable lower cylinder 603 and the movable joint 604 to rotate. A gear ring 605 is provided on the outer side of the movable joint 604. A feed inlet 606 is symmetrically opened in an annular shape at the bottom side wall of the movable lower cylinder 603. A drilling head 607 is provided at the bottom of the movable lower cylinder 603. During operation, the fixed upper cylinder 602 remains stationary while the movable lower cylinder 603 rotates along the axis under the drive of the drive system 9. At this time, the digging device 7 will perform digging work by rotating. After the soil and rock of this layer are excavated, the hydraulic press 2 will drive the fixed upper cylinder 602 to slide downwards. The movable lower cylinder 603 will slide downwards synchronously with the fixed upper cylinder 602 and continue to dig downwards through the end of the drilling head 607 until the specified depth.

[0018] Preferred solutions include Figure 1 and Figure 3 As shown, the drive system 9 includes a drive motor 901. The multiple drive motors 901 are installed on the side wall of the fixed upper cylinder 602 and arranged in a ring symmetrically. The drive motors 901 are connected to drive gears 903 through drive shafts 902. The drive gears 903 are meshed with gear rings 605. The multiple drive motors 901 are of the same model and use the same operating frequency. When the drive motors 901 are started, they will drive the drive gears 903 to rotate. Since the drive gears 903 are meshed with the gear rings 605, they will rotate synchronously, thereby driving the movable joint 604 and the movable lower cylinder 603 to rotate synchronously.

[0019] Preferred solutions include Figure 4 As shown, the excavating device 7 includes a shovel arm 701, which has a box-shaped structure. One end of the shovel arm 701 is connected to the feed inlet 606. A shovel plate 702 is provided on one side of the shovel arm 701, and a soil retaining plate 703 is provided on the other side. A conveyor belt 705 is provided inside the shovel arm 701, and a drive motor 704 is installed on the back of the shovel arm 701 to drive the drive belt. When the movable lower cylinder 603 drives the earth-shoveling arm 701 to rotate, the shovel plate 702 on one side of the earth-shoveling arm 701, together with the soil-retaining plate 703, will shovel the soil and rocks in the foundation pit into the earth-shoveling arm 701. The conveyor belt 705 inside the earth-shoveling arm 701 will further transport the soil and rocks and put them into the movable lower cylinder 603 through the feed port 606.

[0020] Preferred solutions include Figure 5 As shown, the interior of the drilling cylinder 6 is hollow, and an auger blade 11 is installed inside the drilling cylinder 6. The auger blade 11 is coaxially arranged with the drilling cylinder 6. A drive device is installed in the collection cylinder 5 and drives the auger blade 11 to rotate around its own axis. When the soil and rocks inside the earthmoving arm 701 are transported into the drilling cylinder 6, the drive device in the collection cylinder 5 drives the auger blade 11 to rotate. Since the auger blade 11 is set perpendicular to the ground, it can lift the soil and rocks into the collection cylinder 5 at the upper end by rotating, and finally discharge them through the discharge box 10.

[0021] Example Step 1: Erect support frame 1 around the foundation to be constructed, and install excavation equipment on support frame 1. Step 2: Start the drive motor 901. The drive motor 901 drives the movable joint 604 and the movable lower cylinder 603 to rotate synchronously. Step 3: The movable lower cylinder 603 drives the soil-shoveling support arm 701 at the lower end to rotate around the axis. Then, the drive motor 704 on the back of the soil-shoveling support arm 701 is started. The shovel plate 702 shovels the soil and rocks into the soil-shoveling support arm 701, and then the soil and rocks are transported to the interior of the movable lower cylinder 603 through the internal conveyor belt 705. Step 4: Start the drive device in the collection cylinder 5 and control the auger blade 11 to rotate. The auger blade 11 lifts the soil and rocks in the drilling cylinder 6 into the collection cylinder 5. Step 5: The soil and rocks in the collection cylinder 5 are finally discharged through the discharge box 10 and fall into the conveyor plate 8 under the support frame 1, and then conveyed to the designated location by the conveyor plate 8. Step 6: After the soil and rock excavation to a certain depth is completed, start the hydraulic press 2 above the support frame 1. The hydraulic press 2 controls the hydraulic rod 4 to extend downward and applies downward pressure to the collection cylinder 5 and the drilling cylinder 6. The drilling head 607 at the bottom of the drilling cylinder 6 will continue to drill downward, cooperating with the excavation device 7 to drive the entire excavation construction device to continue to excavate downward.
