Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses precast concrete inspection shaft. Referring to fig. 1, a precast concrete manhole includes a well body 1 and a well cover 4.

Referring to fig. 2, the bottom wall of the manhole cover 4 is provided with a connecting plate 81, and the upper part of the connecting plate 81 and the bottom wall of the manhole cover 4

And the connection is realized through bolts. The lower portion of the connecting plate 81 is disposed obliquely and a support rod 8 is rotatably connected at the bottom end. The top end of the supporting rod 8 is provided with a through hole perpendicular to the length direction of the supporting rod 8, the bottom of the connecting plate 81 is provided with a groove for the supporting rod 8 to be embedded, and after the supporting rod 8 is embedded into the groove of the connecting plate 81, a rotating shaft is arranged to sequentially penetrate through the through holes of the connecting plate 81 and the supporting rod 8, so that the supporting rod 8 is rotatably connected with the connecting plate 81.

Referring to fig. 2, the inner wall of the well body 1 is connected with a positioning block 61 through a bolt, a sliding groove is formed in the positioning block 61 and communicated with the side wall of the positioning block 61, and a supporting block 62 is arranged in the sliding groove. The supporting block 62 is provided with a screw rod 71 in a penetrating manner for driving the supporting block 62 to ascend and descend, the screw rod 71 is in threaded fit with the supporting block 62, and the screw rod 71 penetrates out of the top wall of the positioning block 61. The bottom of the screw rod 71 is inserted into the bottom wall of the sliding chute and is in threaded connection with the bottom wall of the sliding chute. The knob 72 is welded at the top of the screw rod 71, so that the screw rod 71 is more convenient and labor-saving to rotate.

Referring to fig. 2, a support block 62 is connected to the bottom of the support bar 8. The support rod 8 is arranged obliquely, and the bottom of the support rod 8 is arranged in the vertical direction and is connected with the side wall of the support block 62 through a bolt.

Referring to fig. 2, there are two support rods 8, and accordingly, there are two support blocks 62 and two positioning blocks 61 and two screw rods 71 engaged with the support blocks 62. Two knobs 72 are correspondingly arranged at the top of each screw rod 71. The distance of the junction of the support rod 8 and the well lid 4 is smaller than the diameter of the well lid 4. Each screw rod 71 is provided with a yielding hole 74 at a position corresponding to the well lid 4, and each yielding hole 74 is communicated with the edge of the well lid 4.

Referring to fig. 2 and 3, when drainage is needed, a worker inserts hands into the two abdicating holes 74, and simultaneously rotates the knob 72 to drive the screw rod 71 to rotate, so that the supporting block 62 is lifted.
