[0002] Pile board type retaining wall is one of common supporting methods, including anti -skid pile and retaining wall between piles. The engineering field elevation is higher than the field elevation, and the pile board type retaining wall is used for supporting the field soil structure, and is mainly used for protecting the road in the field area and guaranteeing the life and property safety of passing pedestrians and employees. The pile board type retaining wall needs to construct anti -skid pile first, and then constructs retaining wall between piles when the anti -skid pile concrete reaches the strength specified in the design.

[0003] Because the field elevation is higher than the field, and the field does not belong to the engineering land range, so in the construction process, the formwork needs to be supported on the two sides of the retaining wall between piles, to ensure that the retaining wall between piles is poured and formed. Because the inclined support cannot be used to support and reinforce the formwork of the outer free surface retaining wall, in the case of limited land range, the inclined support formwork cannot be used, and the inner free surface may not be uniform due to the insufficient soil compaction, which causes the verticality and flatness of the retaining wall between piles to not meet the problem.

[0006] Preferably, a plurality of fixed grooves are equidistantly arranged on the square tube along the length direction, perforated supports are installed on the both ends of the square tube, bolts pass through the fixed grooves and the perforated supports to fix the square tube and the perforated supports, and the perforated supports are abutted with the channel steel.

[0007] Preferably, a pull rod is arranged between the retaining wall and the formwork, and positioning nuts are threadedly connected to the both ends of the pull rod.

[0008] Preferably, a plurality of jacks are equidistantly arranged along the length direction of the formwork.

[0009] Preferably, the pull rod is equidistantly provided with a plurality of along the length direction of the template.

[0010] Compared with the prior art, the utility model has the beneficial effects that:

[0011] The device utilizes horizontally arranged square tubes and channel steels to be connected, utilizes anti-skid piles to be reversely supported, and forms a stable support assembly as a whole. Steel pipes are arranged to be jacks for adjusting the flatness and perpendicularity of the retaining wall formwork, and transmit the formwork force to the support assembly. The device has simple structure, and the manufacturing materials are widely available, and can be used for work without being limited by site conditions. BRIEF DESCRIPTION OF DRAWINGS
