[0003] For example, a combined support device for concrete pouring in highway engineering with the authorization announcement number "CN218540304U" solves the problem of difficult demoulding of the cylinder in the existing combined support device for concrete pouring in highway engineering. The above-mentioned hexagonal prism is pushed by rotating downward to drive the flip block to flip downward, so that the evenly distributed positioning blocks can support the inner wall of the reserved water outlet, thereby ensuring that the position of the cylinder will not shift during the concrete pouring construction, thereby ensuring the accuracy of the position of the reserved outlet. Considering that when pouring concrete for highway projects, the size of the reserved water outlet for the road will be limited due to the width of the road, the shell size in the existing structure is fixed, so the size of other drains cannot be satisfied during use and can fit with the shell, resulting in the support of the drain being limited in scope of use.

[0006] Preferably, a protective mechanism is provided on the outer wall of the cover plate, and the protective mechanism comprises a clamping block, the outer wall of the clamping block is fixedly connected to the cover plate, the outer wall of the clamping block is tightly abutted against a protective ring, and the outer wall of the protective ring is fixedly connected to a blocking ring.

[0007] Preferably, a slide groove is installed on the inner wall of the shell, and the inner wall of the slide groove is slidably connected to the extension plate.

[0008] Preferably, the end of the threaded rod is fixedly connected to the driving member, and a connecting hole is installed on the outer wall of the driving member.

[0009] Preferably, a first circular hole is installed on the surface of the cover plate, a second circular hole is installed on the surface of the disc, and the outer wall of the disc is rotatably connected to the stopper.

[0010] Preferably, the outer wall of the shell is fixedly connected to the anti-sliding block.

[0011] The utility model proposes a combined support device for pouring concrete in road construction, which has the beneficial effects of: the slider is driven by the disc to slide in the track groove on the surface, and the slider drives the shell on the connecting rod to move until the outer wall of the shell is tightly attached to the edge of the reserved water outlet, and the cover plate at the upper end of the shell supports the water outlet, so that the shell can be adjusted and fitted according to the size of the water outlet, and the support of the water outlet will not be restricted.
