Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to the paving technology of cement stabilized macadam. Background Art

[0002] Cement stabilized macadam is a kind of macadam material mixed with a certain proportion of cement and water. It is formed by mixing macadam and cement in a certain proportion and adding an appropriate amount of water for mixing, forming a semi-rigid material with good stability and bearing capacity. This material is widely used in the subbase or base course of projects such as highways, municipal roads, and site foundations.

[0003] When paving cement stabilized macadam, templates need to be set on both sides of the road to enclose the paving area. The templates can determine the paving area and prevent the cement stabilized macadam from spreading outside the designed paving area. The templates can also guide the edges of the cement stabilized macadam layer to be straight and have side edges perpendicular to the ground, which helps to control the width and thickness of the cement stabilized macadam layer.

[0004] During paving, the bottom ends of the templates on both sides of the road are lower than the bottom ends of the designed cement stabilized macadam layer (that is, the bottom ends of the templates are inserted into the soil layer to a certain depth), ensuring that the cement stabilized macadam can completely fill the space inside the templates during the paving process and closely fit with the templates after compaction, forming a flat and solid base course.

[0005] The templates include traditional wooden templates and new steel templates.

[0006] The traditional templates have the following defects:

[0007] 1. Building and demolishing the templates are rather cumbersome, with a large labor intensity during construction and a low construction efficiency. For example, when anchoring the templates to the ground, relying on manpower to hammer the anchor fittings (ground anchors) into the soil not only causes a large labor intensity but also has a low construction efficiency. The labor intensity of pulling out the anchor fittings from the soil during demolition is also very large, and the demolition efficiency is low.

[0008] 2. The existing templates (wooden templates and steel templates) are integral templates, which are not easy to install and disassemble. They occupy a large space during storage and transportation and are not convenient for storage and transportation (the utility model is very convenient to disassemble the anchoring and supporting units, greatly reducing the space occupied during template storage and transportation).

[0009] 3. The templates need to be anchored to the soil on both sides of the road using anchor fittings, and the positional relationship between the anchor fittings and the templates cannot be adjusted, and the positions of the anchor fittings cannot be adjusted as needed (the utility model is convenient to adjust the front and rear positions of the anchoring and supporting units).

[0010] In addition, wooden templates are also easily damaged due to moisture and deformation, thereby affecting the performance of repeated use. Summary of the Utility Model

[0011] The object of the present utility model is to provide a formwork for paving cement stabilized macadam aiming at the defects in the prior art, which is convenient for quick anchoring and removal by mechanical force, reduces labor intensity and improves the efficiency of installation and disassembly.

[0012] To achieve the above object, the formwork for paving cement stabilized macadam of the present utility model includes a retaining plate, which is used for being inserted into the soil on both sides of the road and enclosing the left and right sides of the paving area; the direction pointing to the center line of the road is the inner direction, and the reverse direction is the outer direction; the extending direction of the road is the front-back direction;

[0013] A plurality of anchoring and supporting units are connected to the outer surface of the retaining plate through a connecting unit. The anchoring and supporting unit includes a triangular support plate connected to the retaining plate through the connecting unit. The triangular support plate extends along the width direction of the road. The bottom ends of the front and rear sides of the triangular support plate are respectively fixedly connected with horizontally arranged anchoring plates, and the anchoring plates are used for pressing on the soil; the anchoring plates are threadedly connected with vertically arranged ground anchor bolts. The big head end of the ground anchor bolt faces upward and is used for cooperating with a hand-held electric drill, and the lower end of the ground anchor bolt is used for being inserted into the soil to form an anchoring effect.

[0014] The connecting unit includes a sliding plate and a sliding slot; the sliding slot is vertically arranged and has an opening at its upper end. The outer side wall of the sliding slot has a vertical slot for passing through the triangular support plate, and the vertical slot is communicated with the sliding slot;

[0015] The sliding plate extends along the front-back direction. The front and rear ends of the sliding plate are fixedly connected to the rear surface of the retaining plate, and the middle part of the sliding plate is arranged at an interval from the rear surface of the retaining plate;

[0016] A horizontally arranged through hole is provided on the groove wall of the sliding slot. The sliding plate passes through the through hole and is in sliding fit with the through hole. The sliding slot is used for being plugged and matched with the anchoring and supporting unit.

[0017] The anchoring and supporting unit includes a vertical insertion plate and the triangular support plate. The vertical insertion plate is plugged and matched with the sliding slot. The vertical insertion plate is located outside the sliding plate and is in contact with the sliding plate; the vertical insertion plate is fixedly connected to the triangular support plate outward, and the triangular support plate passes through the vertical slot.

[0018] The vertical insertion plate is connected with a handle rod upward.

[0019] The present utility model has the following advantages:

[0020] When it is necessary to anchor the present utility model, the anchor bolt is rotated by a hand drill, and the anchor bolt is driven to penetrate downward into the soil body to form an anchoring effect. When it is necessary to remove the present utility model, the anchor bolt is rotated in the reverse direction by a hand drill, and the anchor bolt is driven to rise upward to release the anchoring effect. By adopting the present utility model, both anchoring and removal can use the hand drill as the driving force, greatly reducing the labor intensity and significantly improving the installation and disassembly efficiency.

[0021] In the present utility model, the sliding slot is slidably matched with the sliding plate through its through hole, and the sliding slot can be conveniently moved along the sliding plate to change the front and rear positions of the anchoring and supporting unit. During construction, the front and rear positions of each anchoring and supporting unit can be flexibly adjusted according to the actual situation, so as to exert the most suitable stable supporting effect for the construction site.

[0022] The anchoring and supporting unit can stably support the retaining plate, and after the anchor bolt is screwed out from the anchor plate, the anchoring and supporting unit can be conveniently pulled out upward. After the anchoring and supporting unit is pulled out upward from the vertical slot and the sliding slot, multiple anchoring and supporting units can be stored separately from the retaining plate, so that the retaining plate no longer forms a large-space-occupying structure with the anchoring and supporting unit, greatly reducing the space occupied by the present utility model during storage and transportation and facilitating storage and transportation.

[0023] The handle rod is convenient for the user to hold. When inserting or pulling out the anchoring and supporting unit from the sliding slot, it is very convenient for hand-held operation, improving the operation efficiency. Description of the Drawings

[0031] As Figures 1 to 7 shown, the utility model provides a formwork for paving cement stabilized macadam, including an enclosing board 1, which is used to be inserted into the soil (loose soil) on both sides of the road and enclose the left and right sides of the paving area;

[0032] Taking the direction pointing to the center line of the road as the inward direction and the reverse direction as the outward direction (the inside and outside direction is also the width direction of the road, that is, the left and right direction); taking the extension direction of the road as the front and back direction;

[0033] A number of anchoring and supporting units 2 are connected to the outer surface of the enclosing board 1 through a connecting unit. The anchoring and supporting unit 2 includes a triangular support board 3 connected to the enclosing board 1 through the connecting unit. The triangular support board 3 extends along the width direction of the road (that is, the left and right direction is also the inside and outside direction). The bottom ends of the front and back sides of the triangular support board 3 are respectively fixedly connected with horizontally arranged anchoring plates 4, and the anchoring plates 4 are used to press on the soil; the anchoring plates 4 are threadedly connected with vertically arranged ground anchor bolts 5. The big head end of the ground anchor bolt 5 faces upward and is used to cooperate with a hand-held electric drill, and the lower end of the ground anchor bolt 5 is used to insert into the soil to form an anchoring effect.

[0034] When it is necessary to anchor the utility model, the ground anchor bolt 5 is driven to rotate by a hand-held electric drill, and the ground anchor bolt 5 is driven to penetrate downward into the soil to form an anchoring effect. When it is necessary to remove the utility model, the ground anchor bolt 5 is driven to rotate in the reverse direction by a hand-held electric drill, and the ground anchor bolt 5 is driven to rise upward to release the anchoring effect. By adopting the utility model, both anchoring and removal can use the hand-held electric drill as the driving force, the labor intensity is greatly reduced, and the installation and disassembly efficiency is greatly improved.

[0035] The connecting unit includes a sliding plate 6 and a sliding slot 7; the sliding slot 7 is connected to the outer surface of the enclosing board 1. The sliding slot 7 is vertically arranged and has an opening at its upper end. The outer side wall of the sliding slot 7 has a vertical slot 8 for passing the triangular support board 3, and the vertical slot 8 is communicated with the sliding slot 7;

[0036] The sliding plate 6 extends along the front and back direction. The front and back ends of the sliding plate 6 are fixedly connected to the rear surface of the enclosing board 1, and the middle part of the sliding plate 6 is spaced from the rear surface of the enclosing board 1;

[0037] A horizontally arranged through hole 9 is provided on the groove wall of the sliding slot 7. The sliding plate 6 passes through the through hole 9 and is slidably matched with the through hole 9. The sliding slot 7 is used for plugging and matching with the anchoring and supporting unit 2.

[0038] In the utility model, the sliding slot 7 is slidably matched with the sliding plate 6 through its through hole 9, and the sliding slot 7 can be conveniently moved along the sliding plate 6 to change the front and back positions of the anchoring and supporting unit 2.

[0039] The anchoring and supporting unit 2 includes a vertical insertion plate 10 and the triangular support plate 3. The vertical insertion plate 10 is in plug-in fit with the sliding slot 7. The vertical insertion plate 10 is located outside the sliding plate 6 and is connected to the sliding plate 6 (in a pressed connection state during paving, and the pressure comes from the lateral pressure of the cement stabilized macadam on the retaining plate 1; before being subjected to lateral pressure, the vertical insertion plate 10 and the sliding plate 6 can be in clearance fit); the vertical insertion plate 10 is fixedly connected to the outside of the triangular support plate 3, and the triangular support plate 3 passes through the vertical slot 8.

[0040] The anchoring and supporting unit 2 can stably support the retaining plate 1, and after screwing out the anchor bolt 5 from the anchor plate 4, the anchoring and supporting unit 2 can be conveniently pulled out upwards. After pulling out the anchoring and supporting unit 2 upwards from the vertical slot 8 and the sliding slot 7, multiple anchoring and supporting units 2 can be stored separately from the retaining plate 1, so that the retaining plate 1 no longer forms a large-space-occupying structure with the anchoring and supporting unit 2, greatly reducing the space occupied by the present utility model during storage and transportation and facilitating storage and transportation.

[0041] The vertical insertion plate 10 is connected upwards with a handle rod 11. The handle rod 11 is convenient for the user to hold. When inserting or pulling out the anchoring and supporting unit 2 into or from the sliding slot 7, it is very convenient for hand-held operation, improving the operation efficiency.

[0042] When paving the cement stabilized macadam layer in a predetermined area of the road, first install the templates for paving the cement stabilized macadam of the present utility model at the predetermined positions on both sides of the paving area of the road. When installing, the anchoring and supporting unit 2 is not inserted into the sliding slot 7. Insert the lower end of the retaining plate 1 into the loose soil on both sides of the road, so that each anchor plate 4 is pressed on the soil body, and then put on the anchor bolts 5 on each anchor plate 4 respectively, and use an electric drill to drive the anchor bolts 5 to rotate and penetrate downwards into the soil body to form an anchoring effect. When the retaining plate 1 is subjected to the outward pressure of the paved cement stabilized macadam, the outward pressure is transmitted from the retaining plate 1 and the sliding plate 6 to the vertical insertion plate 10, the triangular support plate 3, the anchor plate 4 and the anchor bolts 5. Under the anchoring and supporting action of the triangular support plate 3 and the anchor bolts 5, the stable state of the retaining plate 1 is maintained, ensuring that the edge is neat during the paving of the cement stabilized macadam layer, the cement stabilized macadam will not flow away, and the road edge is neat and uniform, ensuring the paving quality.
