[0026] See also Figure 1 , Figure 2 , this embodiment provides a cast-in-place concrete inspection well construction device, which is mainly composed of an outer formwork 1, an inner formwork 2, tension bolts 3 and an attached vibrator 5. The outer formwork 1 and the inner formwork 2 are both steel formworks, and the outer formwork 1 and the inner formwork 2 are rectangular, circular or square, and the present embodiment is rectangular. The outer formwork 1 and the inner formwork 2 are made according to the design size of the inspection well. The upper and lower ports of the outer formwork 1 are both open structures, which are assembled from four side panels, and the joints are welded and sealed with adhesive strips. A bottom plate 2-1 is welded to the lower end of the inner formwork 2, and the upper port of the inner formwork 2 is an open structure. The inner formwork 2 is assembled from five steel plates, and the joints are welded and sealed with adhesive strips.

[0027] The inner formwork 2 is nested in the outer formwork 1. The gaps between the side plates of the inner formwork 2 and the side plates of the outer formwork 1, and between the bottom plate 2-1 of the inner formwork 2 and the bottom of the well are all casting areas. The outer formwork 1 and the inner formwork 2 are connected by tension bolts 3. The two ends of the tension bolts 3 pass through the side plates of the outer formwork 1 and the inner formwork 2 respectively. Two tension bolts 3 are installed at the bottom and the top of the opposite sides of the outer formwork 1 and the inner formwork 2 respectively. The tension bolts 3 are composed of long screws, nuts and sleeves, with a total of eight. The tension bolts 3 are through-length structures, with four on each side of the template in the horizontal and vertical directions, which are used to fix the outer formwork 1 and the inner formwork 2 and prevent the inner formwork 2 from shifting during use. The part where the screw contacts the concrete is isolated with a plastic sleeve for easy extraction.

[0028] The side plates of the outer formwork 1 and the inner formwork 2 are symmetrically provided with reserved holes 1-1, which are consistent with the direction of the cable tube. The cable passes through here after the construction is completed. The hole sleeve 4 runs through the reserved hole 1-1. The hole sleeve 4 is a sleeve with a hollow structure, and its cross-section is rectangular or circular. The size of the hole sleeve 4 is designed according to the reserved hole 1-1 of the inspection well. When pouring concrete, it passes through the reserved hole 1-1. The hole sleeve 4 provides support and isolation for the concrete at the reserved hole 1-1 to form a closed space.

[0029] The outer side surfaces of the four side panels of the outer formwork 1 are installed with attached vibrators 5, four of which are evenly distributed on each surface and connected in series. Vibration is generated by power supply from the shipping trolley to make the internal concrete dense. The bottom plate 2-1 of the inner formwork 2 is installed with attached vibrators 5, four of which are evenly distributed and connected in series. Vibration is generated by power supply from the shipping trolley to make the internal concrete dense. The attached vibrators 5 are electrically connected to the power supply of the shipping trolley through the wire 6 to introduce current.

[0030] A concrete conveying trough 7 is arranged above the outer formwork 1 and the inner formwork 2. The concrete conveying trough 7 is in the shape of an arc-shaped long trough. It is a two-section telescopic structure and is connected and fixed to a shipping trolley (not shown in the figure) through a bracket 8. The bracket 8 connects the concrete conveying trough 7 and the shipping trolley. The bracket 8 can adjust the position and direction. The concrete transported by the tank truck can flow into the formwork quickly and accurately through the concrete conveying trough 7.

[0031] The use process of this embodiment is: excavate the inspection well foundation trench according to the size, the size is 50cm wider on each side than the designed well size, assemble the outer template 1 outside the foundation pit, put the outer template 1 into the foundation trench, then tie and arrange the steel skeleton according to the design and put it into the outer template 1, assemble the inner template 2 and nest it into the outer template 1, and insert the hole sleeve mold 4 into the reserved hole 1-1, insert the tension bolt 3 and tighten the nut. Start the shipping car, which can use new energy and be equipped with a cargo box, adjust the concrete conveying trough 7 to a suitable position, and connect the attached vibrator 5 to the power supply of the shipping car, and start feeding the concrete conveying trough 7 from the concrete tank truck, and flow into the pouring area. After the bottom plate 2-1 is full, turn on the internal attached vibrator 5, and continue to pour the side plate after vibrating and compacting. After pouring to the top, turn on the external attached vibrator 5 to vibrate and compact the side plate. After all are completed, let it stand for initial setting and then remove the template. After the template is removed, the shipping car can be stored and moved to the next construction site to repeat this process. Embodiment 2
