The template device for the construction of the water stabilization layer of the road bed shown by referring to figures 1-7 comprises templates 1 which are spliced and paved along the length of the edge of the road and are higher than the road bed, wherein the templates are higher than the road bed and are higher than the water stabilization layer or slightly higher than the water stabilization layer so as to effectively block the water stabilization layer and prevent water stabilization layer materials from leaking out from the top end of the templates 1.

The tie mechanism for fixing the template 1 is arranged between the side wall of the template 1 and the inner side of the roadbed, specifically, as shown in fig. 1-2 and 6, the tie mechanism comprises connecting holes 101 which are arranged at the center position of the height of the template 1 and are arranged at intervals along the horizontal length of the tie mechanism, the distance between the holes and the end of the template 1 is not more than 50cm, and the distance between the rest positions is controlled between 1.5m and 2 m. The connecting hole 101 is connected with a drawknot pull rod 2, preferably a 5# cold drawn wire, the length of which is 70 cm to 80cm, and the other end of the drawknot pull rod 2 is fixedly connected with a roadbed. After the templates 1 are spliced according to the trend of the curb, the inner side of each template 1 is fixedly connected with one end of a tie rod 2 through a connecting hole 101, and then the other end of the tie rod 2 is fixed on a road bed.

In order to improve the tie strength of the tie rod 2 to the formwork 1, the tie rod 2 is used to resist the outward force applied to the inner side of the formwork 1 by the water stabilization layer, as shown in fig. 4-5, both sides of the tie rod 2 located in the connecting hole 101 are provided with fixing short rods 3 in parallel contact with both sides of the formwork 1. The fixed short rod 3 and the drawknot pull rod 2 are preferably welded and connected, are respectively positioned at the inner side and the outer side of the template 1 and are in parallel contact with the inner side and the outer side surfaces of the template 1, and the whole structure and the drawknot pull rod 2 form an H-shaped end-side structure. The contact width between the inner surface and the outer surface of the template 1 is increased by fixing the length of the short rod 3, so that the template 1 provides higher tie strength to resist the acting force of the water stabilization layer by the foundation that the tie rod 2 is connected with the roadbed.

In order to facilitate the rapid connection and fixation of the tie rod 2 and the roadbed, as shown in fig. 4, the other end of the tie rod 2 is provided with a fixing ring 21 which is flatly attached to the roadbed, and the tie rod 2 can be formed by bending the end part of the tie rod 2. After one end of the drawknot tie rod 2 is connected with the template 1 through the fixed short rods 3 arranged on two sides, a fixed ring 21 arranged on the other end of the drawknot tie rod 2 is flatly attached to the roadbed, and in the fixed ring 21, steel nails (preferably 10cm in length) can be optionally nailed into a lower structure layer to a certain depth, so that the effect of inwards drawknot fixation on the template 1 through a roadbed foundation is realized, and the outwards acting force of a water stabilization layer on the template 1 is resisted.

In order to facilitate the disassembly of the template device and the alternate use along the length direction of the road edge, as shown in fig. 2 and 6, the connecting hole 101 is in a strip hole structure and is in a shape of one line, the length of the fixed short rod 3 is smaller than that of the connecting hole 101, and the width of the connecting hole 101 is larger than the sum of the diameters of the fixed short rod 3 and the drawknot tie rod 2, so that the fixed short rod 3 and the drawknot tie rod 2 can pass through the connecting hole 101, and after the fixed short rod 3 on one side passes through the connecting hole 101, the drawknot tie rod 2 is rotated, so that the fixed short rod 3 is perpendicular to the length direction of the connecting hole 101, and the fixed short rod 3 is prevented from being separated from the connecting hole 101.

When the tie rod 2 needs to be detached, the outer side or the inner side of the fixed short rod 3 passes through the connecting hole 101 by rotating the tie rod 2, so that the tie rod 2 is detached from the template 1; when the laid water stabilization layer solidifies the drawknot tie rod 2, the connection part of the fixed short rod 3 on the outer side of the template 1 and the drawknot tie rod 2 can be sawed, and the template 1 and the drawknot tie rod 2 can be separated. When constructing along curb length direction, can assemble the curb department in construction the place ahead after dismantling template 1, and tie pull rod 2 can reserve in the water steady layer, can very big save the supporting quantity of template 1, save construction cost, also be convenient for the quick transportation of this template device.

Preferably, in the connection state of the fixed short rod 3 perpendicular to the connection hole 101, the fixing ring 21 is flatly attached to the roadbed, so that the fixing ring 21 at the other end of the tie rod 2 is flatly attached to the roadbed on the basis of ensuring that the fixed short rod 3 achieves a tie action on the template 1, and a steel nail is conveniently and smoothly nailed into the roadbed.

Preferably, in order to keep the balance of the fixing ring 21 and avoid the direction change, as shown in fig. 4, a balance rod 6 is vertically arranged on the tie rod 2 close to the fixing ring 21, and the balance rod 6 is flatly attached to the roadbed, so that the fixing ring 21 can be balanced, and the defect that the fixing short rod 3 is automatically separated from the connecting hole 101 of the template 1 due to the rotation of the fixing short rod under the action of external force is avoided.

In order to facilitate the splicing of the templates 1, a template dismounting mechanism is arranged at the joint end of the adjacent templates 1, specifically as shown in fig. 7, the template dismounting mechanism is a horizontal sleeve 4 arranged at the position, close to the end, of the outer side surface of each template 1, and is preferably arranged symmetrically up and down, and connecting round steel 5 is detachably arranged in the horizontal sleeve 4 of the adjacent templates 1 in a penetrating manner. After the end parts of the adjacent templates 1 are connected, the templates 1 can be quickly spliced by penetrating the connecting round steel 5 into the horizontal sleeve 4 corresponding to the adjacent templates 1, and after the adjacent templates 1 are connected, certain strength support can be provided between the templates, so that the joint of the templates 1 is ensured not to deform when the water stable layer is rolled.

Preferably, the form 1 adopts channel steel, the length of each channel steel is determined according to the curve radius of the line, the smaller the curve radius is, the shorter the length of each channel steel is, and the height of the channel steel is determined according to the layering thickness of the water stabilizing layer.
