Technical Field
The utility model relates to the field of construction in constructional engineering, in particular to a height control positioning device for a highway waveform beam guardrail upright post.
Background
The construction of the wave beam guardrail of the expressway engineering is divided into a roadside guardrail and a central separation belt guardrail, and different construction processes are provided for the two guardrails. For the road side guard rail, the construction of a middle layer under a road surface is generally followed by the construction of a concrete shoulder plate slip form, and then the construction of an upper layer and the guard rail are carried out. The guardrail construction at this moment has road surface or road shoulder board as the benchmark, and the stand is very easy to control the height of stand when beating, only need to mark a mark in stand design exposed height department (with road shoulder interface department), pile to this mark and road shoulder board level can. For the central dividing belt guardrail, because the middle dividing belt is not level with filling soil, the guardrail upright post pile is driven, the exposed height of the guardrail upright post pile does not have a reference standard, and the driven upright post can be uneven, so that the installation and the appearance of the whole guardrail are affected.

Detailed Description
In order that the manner in which the above recited features, objects and advantages of the present utility model are obtained will become readily apparent, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Based on the examples in the embodiments, those skilled in the art can obtain other examples without making any inventive effort, which fall within the scope of the utility model. The experimental methods in the following examples are conventional methods unless otherwise specified, and materials, reagents, etc. used in the following examples are commercially available unless otherwise specified.
The two pillar steel pipes are arranged in parallel, and the included angle between the axial lead of the pillar steel pipe and the axial lead of the square steel pipe is 90 degrees. The square steel tube 4 is a cross bar, and the length is 110 cm to 130cm. The length of the pillar steel pipe 3 is 25-30 cm. The strut steel pipe and the square steel pipe are both made of square steel pipes with the diameter of 25 mm.
The weight of the bottom plate is 3 times of the total weight of the pillar steel pipe and the square steel pipe. The bottom plate is 300 x 200 x 10mm steel plate, welds with the lower extreme of two pillar steel pipes, and the steel plate size is adjustable, guarantees steadily not tumbles and is suitable.
The construction operation steps of the utility model are as follows: in pile driving construction, the height of the control line must be determined. According to the design of the guardrail posts, the exposed height is 890mm, and a scribing line with 590mm (890-300=590) is measured downwards at the top ends of all guardrail posts in advance, wherein the scribing line is the height control line 2 of the guardrail posts. The utility model is put on the pavement beside the middle belt (note that the pavement with the size is an upper layer, if the pavement is other structural layers, the thickness of each structural layer above the structural layer is added to the scribing height), at the moment, the height pointed by the square steel pipe, namely the cross rod, is the exposed height of the upright post of the guardrail, and the pile is driven until the height control line is level with the cross rod.
The concrete construction operation steps are as follows: and (5) intensively scribing the height control lines on the guardrail posts in a field or on site. And (5) lofting the upright post position of the guardrail and determining the plane position. The guardrail upright post is manually aligned, the hammer head of the pile driver starts to beat the guardrail upright post, and a commander corrects the verticality of the guardrail upright post in the driving process at any time. The utility model is placed on the road surface close to the middle belt (as shown in figure 3), and the square steel tube, namely the cross rod 4, is perpendicular to the traffic lane and points to the middle belt, so that the cross rod is attached to the guardrail posts being driven. To ensure the stability of the utility model, the auxiliary personnel can step on the bottom plate with feet. The pile driver continuously blows, when the position to be driven is close, the hammering speed is reduced, the auxiliary personnel carefully observe and command until the height control line on the upright post of the guardrail is flush with the cross rod, the hammering is immediately stopped, and the pile driving process of the upright post is finished. Sequentially advances.
