Description

Technical Field

[0001] This utility model relates to the field of road paving, specifically to a geocell paving brick installation structure. Background Technology

[0002] Paving bricks are a common paving material widely used on urban roads and sidewalks. The typical method of laying paving bricks involves directly placing them on the soil and then tapping them with a rubber mallet to ensure a stable installation. While this method is simple and inexpensive, it presents some problems in practical use.

[0003] For example, in rainy weather, rainwater easily seeps into the bottom of paving stones, causing the soil at the bottom to be eroded and resulting in soil loss. Alternatively, the soil at the bottom of the paving stones may be compacted and deformed under the weight of vehicles and pedestrians, creating hollow areas. These situations all lead to rainwater accumulating at the bottom of the paving stones. When pedestrians step on the paving stones, the accumulated rainwater is squeezed out from the edges, staining pedestrians' clothes or shoes, significantly impacting their travel experience. Utility Model Content

[0004] The purpose of this utility model is to provide a geocell paving brick installation structure that can effectively improve the paving brick life and pedestrian walking experience, and has the characteristics of rapid construction.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A geocell paving brick installation structure includes a geocell frame and a plurality of paving bricks, wherein the geocell frame is laid on a backfill layer.

[0007] The geocell frame includes several extension strips, which are arranged in a crisscross pattern. The extension strips enclose and form several cell units, and the paving bricks are installed one-to-one in the several cell units.

[0008] The longitudinal section of the extension strip is I-shaped, and the paving brick is sandwiched between the upper and lower sides of the extension strip. The extension strip is made of plastic material. Each intersection of the extension strip is provided with a vertically penetrating injection hole, which is used to fill the backfill layer at the bottom of the geocell frame with external filler.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] 1. By setting up a geocell frame and setting up injection holes at the intersection of extension strips, when there are hollow areas in the backfill layer at the bottom of the paving bricks, external filler can be injected into the backfill layer through the injection holes. This not only extends the paving brick life, but also prevents rainwater from accumulating in the hollow areas of the backfill layer, thereby improving the pedestrian walking experience.

[0011] 2. By extending the longitudinal section of the strip into an I-shape, the paving bricks can be stably confined within the cell unit, thus preventing the paving bricks from loosening or shifting and improving the stability of the paving brick installation. Attached Figure Description

[0017] Labeling explanation: 1 Geocell frame, 100 extension strip, 101 cell unit, 102 grouting hole, 2 brick layer, 3 backfill layer. Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0019] like Figure 1-5 The diagram shown is a schematic representation of an embodiment of a geocell tunnel brick installation structure provided by this utility model:

[0020] A geocell paving brick installation structure includes a geocell frame 1 and a plurality of paving bricks 2, wherein the geocell frame 1 is laid on a backfill layer 3.

[0021] The geocell frame 1 includes several extension strips 100, which are arranged in a crisscross pattern. The extension strips 100 enclose each other to form several cell units 101, and the paving bricks 2 are installed in the several cell units 101 in a one-to-one correspondence.

[0022] The extension strip 100 has an I-shaped longitudinal section, and the paving brick 2 is sandwiched between the upper and lower sides of the extension strip 100. The extension strip 100 is made of plastic material. Each intersection of the extension strips 100 has a vertically penetrating injection hole 102, which is used to fill the backfill layer 3 at the bottom of the geocell frame 1 with external filler 4. It should be noted that the vertical portion of the I-shaped section has a height corresponding to the paving brick 2 and a thickness of 0.1-0.2 cm, while the upper and lower horizontal portions have a width of 0.4-1.6 cm and a thickness of 0.1-0.2 cm.

[0023] Specifically, the external filler 4 is selected as an expandable filler material such as foamed concrete or foamed sealant.

[0024] Preferably, the extension strip 100 is made of polyethylene or polypropylene, so the geocell frame 1 has good elastic-plastic shape, which allows the geocell frame 1 to be folded and stored, and to be restored to a flat state under the action of elastic recovery. This feature is formed by the properties of the material itself, so it will not be described in detail here.

[0025] Preferably, the geocell frame 1 is integrally formed.

[0026] Preferably, the backfill layer 3 is a sandy soil layer.

[0027] In this embodiment, all compartment units 101 have the same specifications. However, in some embodiments, several extension strips 100 are arranged in a crisscross pattern at different intervals, which can make the compartment units 101 have a variety of different specifications to adapt to different specifications of paving bricks 2.

[0028] The general method of using this utility model is as follows:

[0029] First, the geocell frame 1 is laid on the surface of the pre-set backfill layer 3, and then the paving bricks 2 are installed. Since the extension strips 100 are made of plastic material, they have a certain elastic deformation capacity. When installing the paving bricks 2, the upper edge of the extension strips 100 can be pried up or hooked up by installation tools such as prying tools or hooks, so that the paving bricks 2 can be smoothly placed in the corresponding geocell unit 101. At this time, the paving bricks 2 are sandwiched between the upper and lower sides of the extension strips 100 around them, so as to achieve stable installation of the paving bricks 2.

[0030] If, during long-term use, the backfill layer 3 at the bottom of the paving brick 2 is lost or deformed due to factors such as rain erosion or trampling by pedestrians, resulting in a hollow area under the paving brick 2, external filler 4 can be injected into the backfill layer 3 at the bottom of the paving brick 2 through the injection hole 102 to restore the supporting effect of the backfill layer 3 on the bottom of the paving brick 2. In summary, this utility model can effectively improve the paving life of the paving brick 2 and the pedestrian walking experience.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
