Abstract
The invention provides a positioner which can improve guard post construction work so as to shorten the construction period and lower the cost and improve the positioning precision of a guard post as well as a construction method of the steel pipe guard post. The positioner comprises a positioner base and an auxiliary positioning pipe which is located above the positioner base, wherein a rectangular frame is arranged at the periphery of the auxiliary positioning pipe, and the auxiliary positioning pipe can be connected to the positioner base through four groups of adjustable jacks. The plane position and the perpendicularity of the steel pipe guard post are controlled by precisely lofting the position of the positioner through a total station, and the positioning precision of the guard post can be greatly improved by controlling the elevation of a post top through a level instrument; the used steel pipe guard post can be pulled out from a soil body by adopting a vibrating pipe pulling-out device after foundation pit engineering construction is finished, and the pulled-out steel pipe guard post further can be used again, so that the purpose of reusing the steel pipe guard post is achieved.

Preferably, described adjustable jack quadrangularly is arranged between localizer pedestal and auxiliary positioning pipe。
The present invention also provides for a kind of steel pipe fender post construction method adopting localizer described in the claims, comprises the steps:
1) smooth location, builds both sides concrete foundation, and in concrete foundation pre-buried angle steel；
2) the installation hole for placing steel tubes fender post, installation positioner pedestal are dug in rotation, and are welded and fixed with pre-buried angle steel；
3) adjustable jack and auxiliary positioning pipe are installed successively, and check auxiliary positioning pipe plane coordinates；
4) coordinate check errorless after, lift steel pipe fender post, steel pipe fender post is penetrated auxiliary positioning pipe successively；
5) by adjustable jack adjustment steel pipe fender post top to design altitude；
6), after the lifting of steel pipe fender post puts in place, uniformly backfilling about, fine sand is high to stake top mark；
7) step 1) is repeated to 6), until completing the construction of all fender posts of steel pipe。
Wherein in step 3), described in check auxiliary positioning pipe plane coordinates method particularly includes: adopt total powerstation and level gauge to remeasure plane coordinates and the elevation of auxiliary positioning pipe。
Compared with the prior art, the present invention has the beneficial effect that:
1, the present invention is by improving the location mode of fender post, it is possible to be greatly improved the positioning precision of fender post；
2, the present invention have selected reusable steel pipe fender post, has reached to economize on resources and reduce the purpose of cost；
3, present invention utilizes reusable steel pipe fender post localizer, improve steel pipe fender post construction speed, shorten the construction period；
4, each structure member form of the present invention is simple, can concentrate in factory and make, and in-site installation is easy to use。

Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of preferred implementation of the present invention is described in detail。
As shown in Figure 1,2 and 3, described localizer includes localizer pedestal 10, auxiliary positioning pipe 20 and adjustable jack 30。Described localizer pedestal 10 is formed by two H profile steel longerons and two H profile steel beam weldings, is used for supporting auxiliary positioning pipe 20, and this auxiliary positioning pipe is through localizer pedestal and downwardly extends。Described auxiliary positioning pipe 20 is connected with described localizer pedestal 10 by adjustable jack 30, this auxiliary positioning pipe is used for plan-position and the control of gradient of assisting steel pipe fender post to construct, adopt steel plate and steel pipe in factory process molding, auxiliary positioning pipe periphery has rectangular box 21, for increasing and the contact area of adjustable jack, improve device stability。
Described adjustable jack 30 adopts DTC type accurate adjustment jack, and the present embodiment adopts four groups of adjustable jack pair auxiliary positioning pipes to be adjusted, and quadrangularly is arranged between localizer pedestal and auxiliary positioning pipe。
The present invention also provides for a kind of steel pipe fender post construction method adopting above-mentioned localizer, in conjunction with accompanying drawing 4-7, Specific construction step is described:
Step one, smooth location, build both sides concrete foundation 40, and in concrete foundation pre-buried angle steel 50, with reference to Fig. 4；
