Description

Technical Field

[0001] This invention belongs to the field of municipal engineering technology and relates to a construction method for reserving tree pits in municipal engineering. Background Technology

[0002] Municipal road construction projects often include landscaping projects, namely planting roadside trees. Since the structural layer of sidewalks is mostly made of concrete, it is necessary to set up formwork in advance and reserve the location of tree pits before the concrete foundation is constructed.

[0003] In building construction, wooden formwork is often used and set up at the tree pit location. However, during the concrete pouring process, the lateral pressure on the formwork will cause the formwork to tighten. After the concrete has cured, the tree pit formwork is difficult to disassemble, which can easily damage the formwork, wasting time and effort and failing to meet the requirements for construction and use.

[0004] Therefore, there is an urgent need to design a construction method for reserving tree pits in municipal engineering projects to solve the technical problems existing in the current technology. Summary of the Invention

[0005] The purpose of this invention is to at least partially solve some of the technical problems existing in the prior art, and to provide a construction method for reserved tree pits in municipal engineering. The method has a reasonable structure and is convenient to construct.

[0014] S23, the upright plate is fixed to the opening of the U-shaped structure using a connecting device;

[0015] S24, connect the pins between the vertical keels of adjacent uprights.

[0016] In step S24, the pin is first installed on the unit plate with the hinge, and then the pin is installed between the upright plates located at the opening of the U-shaped structure.

[0043] S1. Based on the dimensions of the reserved tree pit, prefabricate the components of the tree pit template 100; the components of the tree pit template 100 include uprights 1, connecting devices 2, hinges 3, pins 4, and... Figure 8 The fixing bolt 6 shown is as follows: Figure 2 As shown;

[0044] S2, the unit panel 100a of the assembled tree pit template 100, the unit panel 100a includes a pair of upright panels 1, the sides of the upright panels 1 are configured with Figure 8 The vertical keel 5 shown is connected and fixed to the adjacent vertical plates 1 by pins 4; there are four unit plates 100a, three of which are equipped with hinges 3, and the hinges 3 are connected to the adjacent vertical plates 1 by fixing bolts 6; the adjacent unit plates 100a are fixed together by the connecting device 2.

[0045] The connecting device 2 includes a connecting post 21 and a connecting cylinder 22; the connecting post 21 is a cylinder with protrusions 21a on its outer periphery, such as... Figure 3 As shown; the connecting cylinder 22 is a tubular structure, and its end is provided with a snap-fit ​​groove 22a, as shown. Figure 4 As shown; the protrusion 21a matches the size of the snap-fit ​​groove 22a.

[0046] Furthermore, the connecting column 21 and the connecting cylinder 22 are welded to the side of the upright plate 1, the opening direction of the snap-fit ​​groove 22a is consistent with the length direction of the upright plate 1, and the protrusion 21a is arranged perpendicular to the side of the upright plate 1, such as... Figure 5 As shown.

[0047] Figure 5 In the process, the outer end of the upright plate 1 of unit plate 100a is provided with a connecting post 21 or a connecting cylinder 22. If the upright plate 1 of unit plate 100a is provided with a connecting post 21, then the upright plate 1 of adjacent unit plates 100a is provided with a connecting cylinder 22; adjacent unit plates 100a are fixed together by the connecting post 21 and the connecting cylinder 22.

[0048] Furthermore, the protrusion 21a is arranged along the length direction of the connecting post 21, and the snap-fit ​​groove 22a is arranged along the length direction of the connecting cylinder 22, so as to facilitate the snap-fit ​​fixing of the connecting post 21 and the connecting cylinder 22.

[0049] Figure 3 In the middle, the protrusion 21a is provided on the upper part of the connecting post 21, and its length is 1 / 4 to 1 / 3 of the length of the connecting post 21; the length of the snap-fit ​​groove 22a is equal to the length of the protrusion 21a of the interlocking connecting post 21, so as to ensure that the upper and lower end surfaces of the unit plate 100a are parallel to each other and located on the same horizontal plane.

[0050] In one embodiment of the present invention, the connecting column 21 and the connecting cylinder 22 are made of stainless steel and are welded to the side of the vertical plate 1 made of carbon steel. The two are interlocked to connect adjacent unit plates 100a. To ensure smooth installation, a wear-resistant layer is provided on the mating surface of the protrusion 21a and the interlocking groove 22a. The wear-resistant layer is made of a non-metallic material, such as polytetrafluoroethylene, and is sprayed or bonded to the side of the protrusion 21a to improve the ease of installation of the connecting column 21.

[0051] S3, the tree pit template 100 is placed in the tree pit, and concrete is poured and cured in the area outside the tree pit.

[0052] S4. After the concrete has cured, remove the tree pit formwork 100.

[0053] As an embodiment of the present invention, in step S2, the tree pool template 100 is assembled, and its flowchart is as follows: Figure 6 As shown, it includes:

[0054] S21, the hinge 3 is connected between adjacent uprights 1 to form three unit plates 100a with hinge 3;

[0055] S22, the unit plate 100a with hinge 3 is fixed together by the connecting device 2 to form a U-shaped structure;

[0057] S24, connect the pin 4 between the vertical keels 5 of the adjacent upright plate 1.

[0058] In step S24, the pin 4 is first installed on the unit plate 100a with the hinge 3, and then the pin 4 is installed between the upright plates 1 located at the opening of the U-shaped structure. This is because the upright plate 1 without the hinge 3 has a certain degree of freedom, and installing the pin 4 at this point last helps to ensure ease of installation.

[0059] As an embodiment of the present invention, the flowchart for removing the tree pit template 100 in step S4 is as follows: Figure 7 As shown, it includes:

[0060] S41, Remove the pin 4 between adjacent vertical plates 1;

[0062] S43, the inwardly shrinking tree pool template 100 is removed from the entire tree pool for reuse.

[0063] In this invention, the tree pit formwork 100 includes four unit panels 100a, one of which is not equipped with a hinge 3. This ensures that the tree pit formwork 100 can retract inwards during installation and disassembly, thereby improving the ease of assembly and disassembly of the tree pit formwork 100. The technical solution provided by this invention solves the problem of inability or difficulty in demolding after concrete pouring in traditional technologies, effectively improving the efficiency of pre-reserved tree pit construction.

[0064] As one embodiment of the present invention, the pin 3 has an L-shaped structure and is formed by bending a round rod, such as... Figure 9 As shown. Figure 2 In the process, the unit plate 100a includes a pair of pins 3, and the pins 3 of adjacent upright plates 1 are arranged crosswise.

[0065] The vertical plate 1 also includes a horizontal keel 5a, such as Figure 5 As shown, there is a pair of transverse keels 5a, which are located at the upper and lower ends of the vertical plate 1; the connecting device 2 is located between the transverse keels 5a.

[0066] The tree pit template mentioned in this invention can be folded with hinges to reduce space occupation, which is conducive to improving the organization and storage of on-site items and improving the on-site management level of municipal engineering projects.

[0067] Compared with the shortcomings and deficiencies of existing technologies, the present invention provides a construction method for reserved tree pits in municipal engineering. It has a reasonable structure and is easy to construct. The tree pit formwork adopts a modular structure, which is conducive to the inward shrinkage and dismantling of the tree pit formwork, effectively improving construction efficiency and ensuring the construction quality of the reserved tree pits.

[0068] This invention is not limited to the above-described embodiments. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
