Embodiment 1

[0027] Embodiment 1: A kind of support device for the construction protection and support of the asphalt pavement inspection well in the middle repair, such as figure 1 and figure 2 Shown, comprise telescoping main support steel pipe 1 and 2, abdominal support tripod 4 and top plane flat tripod 6, telescoping main support steel pipe is by the steel pipe 1 of upper length 1.2m, inner diameter 8cm and lower length 0.6m, outer A steel pipe 2 with a diameter of 7.5 cm is connected by a circlip device 3, and small holes are arranged under the upper steel pipe 1 according to the size of the circlip for telescopic use of the lower steel pipe 2. Fix it at the steel bar of the inspection well ladder.

[0028] Abdominal support tripod 4 is welded by three hollow steel pipes with an inner diameter of 4 cm, one side of which is connected to the main support steel pipe 1 through a pin 5 at the apex of the triangle, and a steel rod with a diameter of 3.5 cm is passed through the hollow pi...

Embodiment 2

[0036] Embodiment 2: Another kind of support device for the construction protection and support of the asphalt pavement inspection well in the middle repair, such as Figure 1-3 As shown, it includes a telescopic main support steel pipe, a belly support tripod and a top flat tripod, and the lower end of the telescopic main support steel pipe is provided with a card slot that is engaged with the shaft wall ladder. Wherein, the telescopic main support steel pipe includes an upper main support steel pipe and a lower main support steel pipe, the two are set together, and a locking mechanism is arranged at the set part, and the clamping groove is located at the lower end of the lower main support steel pipe.

[0037] The locking mechanism has various forms. In this embodiment, positioning holes are set on the wall of the outer casing and positioning bolts or inward elastic pins are installed, and a series of adjusting holes are set on the wall of the inner casing, and the positionin...

Embodiment 3

[0040] Embodiment 3: on the basis of embodiment 1 or 2, as Figure 4 , Figure 5 and Figure 6 Shown, on the center rod that connects between two sides of abdomen support tripod, be connected with telescopic adjusting rod. The adjusting rod includes upper and lower center rods, which are respectively screw rods and are respectively connected in corresponding upper and lower nuts, and connecting rods are fixed between the upper and lower nuts.

Abstract

The invention discloses a construction protection supporting device for an inspection well of a medium repair asphalt pavement and a using method thereof, and belongs to the field of municipal engineering construction. The construction protection supporting device for the inspection well is a triangular frame supporting system and comprises retractable main supporting steel pipes, an abdominal supporting triangular frame and a top face horizontally-arranged triangular frame; the triangle vertex of one side of the abdominal triangular frame is connected with the main supporting steel pipes through rotatable bolts, the other side of the abdominal triangular frame is provided with a hollow pipe, a steel bar rod penetrating into one side of the horizontally-arranged triangular frame is connected with the hollow pipe, a steel bar hook welded to the triangle vertex of the other side of the horizontally-arranged triangular frame is inserted into the corresponding main supporting steel pipe tobe connected with the main supporting steel pipe, so that the triangular supporting system is formed and the triangular supporting system is used for supporting a temporary cover plate of the inspection well during milling cutting operation of the old pavement. The triangular frame supporting deice is convenient to machine, easy to operate, foldable and convenient to carry, when used for supporting the cover plate of the inspection well, the triangular frame supporting deice is stable and firm, and the influence of construction debris on facilities in the well can be avoided.

Description

technical field [0001] The invention relates to an auxiliary support tool in the field of municipal road construction, in particular to a construction protection support device for an inspection well on an asphalt pavement during intermediate repair. Background technique [0002] The quality of municipal engineering has a major impact on the image of the government and the appearance of the city. In recent years, with the rapid development of the national economy, the infrastructure construction of municipal roads is also developing rapidly, and people's requirements for the quality of municipal roads are also getting higher and higher. . The damage and repair of municipal asphalt pavement is an important part of municipal engineering. How to repair the damaged pavement faster and better without affecting the production and life of citizens has become an important engineering problem that municipal departments need to solve urgently. However, in the process of pavement repa...
