Description

TECHNICAL FIELD

[0001] The utility model relates to road surface water stable base construction technical field, concretely is a kind of road surface water stable base construction formwork device. BACKGROUND

[0002] Road surface water stable base construction is an important link in road construction, which is directly related to the bearing capacity and service life of the road. Water stable base, full name is cement stabilized macadam base, is a kind of semi-rigid base material formed by mixing raw materials such as cement, macadam, sand, etc. in a certain proportion, adding an appropriate amount of water, and then paving and compacting by machinery. In the process of road surface water stable base construction, formwork is needed. Formwork can ensure that the paving and compaction of water stable base are in accordance with the size and shape of the design requirements. Through the constraint of formwork, the consistency of key parameters such as the width, thickness and slope of the base can be ensured, thereby ensuring the overall stability of the road structure and driving safety.

[0003] In the prior art, the formwork is generally supported by an inner support frame. The inner support frame is inserted through the through slot formed in the outer wall of the mold, and then the inner support frame is rotated. The position of the formwork is limited by the two limiting rods on the outer wall of the inner support frame. The other end of the inner support frame is driven into the ground to fix the inner support frame and support the formwork. By supporting the formwork from the inside, the overall structural stability of the formwork can be improved.

[0004] However, since the inner support frame is designed in one piece, when the construction is completed, a part of the inner support frame will be buried inside the water stable layer material. When the formwork is to be disassembled, one of the limiting rods needs to be removed manually or with some simple mechanical tools (such as a hammer, a cutting machine, etc.). The formwork can only be removed after the limiting rod is removed. Since the inner support frame has high strength, this method is time-consuming and labor-intensive. Therefore, it is necessary to provide a road surface water stable base construction formwork device to solve the above problems. UTILITY MODEL CONTENTS
