Description

technical field

The present utility model relates to the field of asphalt and concrete pavement construction and is particularly a level control device for an asphalt pavement.

State of the art

The asphalt pavement structure generally consists of a road base, a limestone soil layer, a graded gravel layer, upper and lower waterproofing layers, a lower asphalt layer, a middle asphalt layer, and an upper asphalt layer. The roadbed supports dozens of tons of loads. The requirements for the overall strength of the road substructure are quite high and the individual pavement layers differ in their thickness. Therefore, the quality of the covering and the repair can hardly be guaranteed. The quality of the road substructure is also severely affected, which endangers future road safety.

A (road) finisher is usually used to lay the surface of an asphalt surface. The paver, as a construction device mainly used for laying different materials on a base course and a surface course on an expressway, can lay and level different materials evenly on the base course. However, the leveling beams found in prior art pavers are not able to effectively control the height of the pavement and the leveling beams for laying pavements with transverse slopes cannot effectively control the thickness of the transverse slopes installed on the pavements, so that the quality of the covering cannot be exactly guaranteed.

Technical solution

The aim of the present utility model is that the present utility model provides a level control device for an asphalt pavement, which solves the problem of the prior art that the leveling beams therein cannot effectively control the level of the pavement and that the leveling beams for the laying of paving with transverse slopes cannot effectively control the thickness of the transverse slopes installed on the pavement, so that the quality of the pavement is not exactly guaranteed.

• Schritt 1: Gemäß den Anforderungen für die Spezifikation des zu verlegenden Belags und der Überlappung wird eine Totalstation oder RTK für die Absteckung einer Punktposition einer Seitenlinie des Straßenunterbaus um 20 m in Längsrichtung verwendet. Die Punktabstände können in einem Kurvenabschnitt entsprechend angepasst werden. Eine aufrechte Stange 1 wird auf einer zu befestigenden Kante aufgeschlagen. Beim Einschlagen wird ein Levellineal gegen die aufrechte Stangel gelegt, um zu prüfen, ob die aufrechte Stange 1 senkrecht steht.
• Schritt 2: Die verstellbare Hülse 2 wird auf die aufrechte Stange 1 aufgesetzt und die Position entsprechend einer Punktposition so eingestellt, dass sie senkrecht zu einer Linienrichtung steht. Nach der Einstellung wird die erste Schraube 4 vorläufig festgeschraubt.
• Schritt 3: Die Höhe des Kugelkopfes 81 wird mit einem Nivelliergerät gemessen (oder eine Totalstation wird für die trigonometrische Höhe eines anteroposterioren Spiegels verwendet), und die Höhe der Querstange 7 wird berechnet. Aus dem Vergleich zwischen der tatsächlich gemessenen Höhe (Belagslockerungsgrad eines Asphalts) und der geplanten Höhe wird eine Höhendifferenz berechnet. Die erste Schraube 4 wird gelockert.

Die zweite Schraube 82 wird festgeschraubt. Ein Drahtspanner wird an beiden Enden verwendet, um den Draht so zu spannen, dass er eben ist.
• Schritt 6: Nach der Positionierung kann die Verlegung des Belags erfolgen, indem die Einführungsanlage des Fertigers auf den Begrenzungsdraht eingestellt wird.
• Schritt 7: Während der nächsten strukturellen Konstruktion werden zwei der ersten Schrauben 4 gelockert. Die Position der verstellbaren Hülse 2 auf der aufrechten Stange 1 wird durch Multiplikation der Dicke mit dem Belagslockerungsgrad eines entsprechend der Gestaltung des Schichtaufbaus nach oben angepasst. Schritt 3 und Schritt 5 werden wiederholt.

• Step 1: According to the requirements for the specification of the pavement to be laid and the overlap, a total station or RTK is used to stake out a point position of a side line of the road bed by 20 m in the longitudinal direction. The point spacing can be adjusted accordingly in a curve section. An upright bar 1 is pitched on an edge to be fastened. When hitting, a level ruler is placed against the upright stick to check whether the upright stick 1 is vertical.
• Step 2: The adjustable sleeve 2 is put on the upright bar 1, and the position is adjusted according to a point position to be perpendicular to a line direction. After the adjustment, the first screw 4 is temporarily tightened.
• Step 3: The height of the ball head 81 is measured with a level (or a total station is used for the trigonometric height of an anteroposterior mirror) and the height of the crossbar 7 is calculated. From the comparison between the actually gemes A height difference is calculated from this height (degree of surface loosening of an asphalt) and the planned height. The first screw 4 is loosened. The height of the crossbar 7 is adjusted according to the calculated height difference to match the planned height. The first screw 4 is tightened for fixation.
• Step 4: The data on the scale of the upright bar 1 is read, and the data and the position of the pole number thereof are recorded.
• Step 5: The perimeter steel wire is placed on the crossbar 7. The steel wire is pulled taut and held in place by a spacer to prevent marking. The second screw 82 is tightened. A wire tensioner is used at both ends to tension the wire so it is level.
• Step 6: After positioning, the paving can be laid by adjusting the paver's insertion system to the perimeter wire.
• Step 7: During the next structural construction, two of the first screws 4 are loosened. The position of the adjustable sleeve 2 on the upright bar 1 is adjusted upwards by multiplying the thickness by the degree of pavement loosening according to the design of the layered structure. Step 3 and Step 5 are repeated.
