Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 2 and fig. 3, a positioner that slope shape foundation ditch construction was used, including four lower mounting 1, four upper mounting 2 and a plurality of locating lever, four lower mounting 1 are used for setting up four reentrant corners in the foundation ditch respectively, four upper mounting 2 are used for setting up four external corners in the foundation ditch respectively, all locating levers are by four lower locating levers 3, four upper locating levers 4 and four diagonal positioning poles 5 constitute, every lower locating lever 3 level sets up between two adjacent lower mounting 1 and is located the upper end of these two lower mounting 1, every upper locating lever 4 level sets up between two adjacent upper mounting 2 and is located these two upper mounting 2 upper ends, every diagonal positioning pole 5 slope sets up under mounting 1 and correspond between upper mounting 2 and is located this lower mounting 1 and corresponds upper mounting 2 upper end.

Like this, when constructing the foundation ditch of sump pit or elevartor shaft, at first the foundation ditch rough excavation shaping, then insert the soil layer with four lower mounting and four last mounting parts respectively according to design drawing in four reentrant corners and four external corner positions of foundation ditch, and guarantee that the mounting inserts the soil layer and have certain degree of depth, thereby avoid leading to the fact the unsafe problem of location because of the soil property reason, then connecting positioning rod between the mounting, wherein fix down the locating lever between two adjacent lower mountings, fix the locating lever between two adjacent upper mountings, down the mounting with correspond and go up fixed diagonal positioning pole between the mounting, just so constitute positioner, then based on positioner, be about to positioner as the reference, dig out the soil layer of backing layer thickness downwards, adopt 1 again: 3, filling cement mortar, taking out the positioning device after the cushion layer construction is finished, and trowelling the positioning device to finish the construction of the foundation pit.

At the job site, locating lever and mounting all can adopt the reinforcing bar to make, and the locating lever passes through welded mode welded fastening at the mounting upper end.
