Description

Technical Field

[0001] This invention relates to the field of site hardening technology, and more specifically, to a site hardening device and its manufacturing and usage methods. Background Technology

[0002] Site hardening refers to the hardening of soft ground surfaces in production activities to meet production needs. Currently, the most common site hardening method is pouring concrete, which requires a lot of manpower and resources and has low work efficiency. Summary of the Invention

[0003] This invention provides a site hardening device and its manufacturing and usage methods, which can overcome some or all the defects of the prior art.

[0004] According to the present invention, the site hardening device includes: a device body, wherein the device body is formed from top to bottom into an interconnected surface layer, a permeable layer and a waterproof layer, a hardening medium is provided between the surface layer and the waterproof layer, and the hardening medium is mixed with water to undergo a hydration reaction to generate the hardening layer; a plurality of permeable nails are provided at the permeable layer, and the permeable nails are used to guide water from the upper end of the permeable layer to the lower end of the permeable layer.

[0005] In this invention, water can penetrate through the surface layer to the permeable layer, and the hardening medium can undergo a hydration reaction with the water to generate a hardening layer, thereby achieving the hardening of the device body; the permeable nails can guide water from above the permeable layer to below the permeable layer, so the hardening medium below the permeable layer can also mix better with the water to generate a hardening layer. At the same time, the permeable nails can better support the surface layer, so that the hardening medium reduces the impact of surface layer deformation on the final hardened layer surface during the hydration reaction process.

[0006] As a preferred option, the surface material is geotextile.

[0007] In this invention, the geotextile has a low cost and good water absorption, which can better allow water to seep into the hardened cavity.

[0008] Preferably, the seepage nail includes a mating part and a fixing part integrally disposed along the height direction. The mating part is used to mate with the surface layer and the seepage layer, and the fixing part is used to mate with the hardening layer. The seepage nail forms a through water channel along the axial direction.

[0009] In this invention, the mating part can be bonded to the surface layer and the permeable layer, and the fixing part can be combined with the hardening layer, thus achieving the supporting function of the fixing part better; the water guiding channel can guide water from the surface layer to below the permeable layer, thus achieving the hydration reaction of the hardened medium below the permeable layer better.

[0010] Preferably, the mating part includes a cylindrical mating piece, and the fixing part includes an arc-shaped fixing strip formed along the circumference of the mating piece. The fixing strip contracts to form a conical surface, and the fixing strip has a convex surface and a concave surface. Guide strips are formed radially at both ends of the convex surface in the width direction.

[0011] In this invention, by setting a mating piece, it can be better bonded and mated with the surface layer and the water-permeable layer; by setting a fixing strip, it can be better mated with the hardened layer.

[0012] Preferably, the water guide channel includes a first sub-channel formed at the mating plate, all concave surfaces together forming a second sub-channel, and the first sub-channel and the second sub-channel are connected; adjacent guide strips form a third sub-channel, and the third sub-channel is connected to the second sub-channel.

[0013] In this invention, by setting a first sub-channel, a second sub-channel, and a third sub-channel, the flow guidance from the water surface layer to below the permeable layer is preferably achieved.

[0014] Preferably, the hardening medium is dry concrete mixture.

[0015] In this invention, the dry concrete mixture has good water absorption and good rigidity after solidification, thus enabling the hardening of the ground.

[0016] Preferably, the permeable layer is made of woven polyethylene and polypropylene materials.

[0017] In this invention, polyethylene and polypropylene have poor water absorption, so the woven polyethylene and polypropylene materials have better water permeability, thus water can better penetrate the permeable layer.

[0018] Preferably, the waterproof layer is made of polyvinyl chloride.

[0019] In this invention, polyvinyl chloride has better water resistance and can better retain water in the hardened cavity.

[0020] The method for manufacturing a site hardening device according to the present invention includes the following steps:

[0021] Step S1: Use a mold to injection mold and produce drainage nails;

[0022] Step S2: Lay the waterproof layer, then lay the hardening medium on the waterproof layer and then lay the seepage layer. Vertically insert seepage nails into the seepage layer.

[0023] Step S3: Lay a hardening medium on the permeable layer;

[0024] Step S4: Lay a surface layer on the surface of the permeable layer.

[0025] In this invention, the above steps provide a better production site hardening device.

[0026] The method of using the site hardening device according to the present invention includes the following steps:

[0027] Step S1: Use a mixture of 3:7 lime and soil to compact the ground to be laid to form a base;

[0028] Step S2: Lay the device body on the base, with the waterproof layer facing the ground;

[0029] Step S3: Secure the device body to the ground using rivets;

[0030] Step S4: Pour water to soak the device body and wait for the device body to air dry naturally.

[0031] In this invention, the above steps enable the device body to bond with the ground more effectively and ensure complete hydration within the device body; thus, ground hardening can be achieved more effectively. Attached Figure Description

[0033] Figure 2 This is a schematic diagram of the seepage nail structure in Example 1. Detailed Implementation

[0034] To further understand the content of this invention, a detailed description of the invention is provided in conjunction with embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0035] Example 1

[0036] This embodiment provides a site hardening device, which includes a device body 100. The device body 100 is formed from top to bottom into an interconnected surface layer 110, a water-permeable layer 120, and a waterproof layer 140. A hardening medium is provided between the surface layer 110 and the waterproof layer 140. The hardening medium mixes with water to form a hydration reaction to generate a hardening layer 130. A plurality of water-permeable nails 250 are provided at the water-permeable layer 120. The water-permeable nails 250 are used to guide water from the upper end of the water-permeable layer 120 to the lower end of the water-permeable layer 120.

[0037] Through the above scheme, water can penetrate from the surface layer 110 into the permeable layer 120, and the hardening medium can undergo a hydration reaction with the water to generate the hardening layer 130, thereby achieving the hardening of the device body 100; the permeable nails 250 can guide water from above the permeable layer 120 to below the permeable layer 120, so the hardening medium below the permeable layer 120 can also mix better with the water to generate the hardening layer 130. At the same time, the permeable nails 250 can better support the surface layer 110, so that the hardening medium reduces the impact of the deformation of the surface layer 110 on the surface of the final hardened layer 130 during the hydration reaction.

[0038] In this embodiment, the permeable layer 120 is made of geotextile.

[0039] Among them, geotextiles have a lower cost and better water absorption, which allows water to seep into the hardened cavity more effectively.

[0040] In this embodiment, the water-permeable nail 250 includes a mating part 251 and a fixing part 252 integrally disposed along the height direction. The mating part 251 is used to mate with the surface layer 110 and the water-permeable layer 120, and the fixing part 252 is used to mate with the hardening layer 130. The water-permeable nail 250 forms a through water-guiding channel along the axial direction.

[0041] The mating part 251 can be bonded to the surface layer 110 and the permeable layer 120, and the fixing part 252 can be combined with the hardening layer 130, thus achieving the supporting function of the fixing part 252 better; the water guiding channel can guide water from the surface layer 110 to below the permeable layer 120, thus achieving the hydration reaction of the hardened medium below the permeable layer 120 better.

[0042] In use, when water is poured onto the surface of the top layer 110, the water permeates from the surface of the top layer 110 to the hardening medium and water channel below the top layer 110. The water in contact with the hardening medium undergoes a hydration reaction, while the water in the water channel flows along the water channel to the hardening medium below the permeation layer and undergoes a hydration reaction with the hardening medium below the permeation layer.

[0043] In this embodiment, the mating part 251 includes a cylindrical mating piece 2511, and the fixing part 252 includes an arc-shaped fixing strip 2521 formed around the mating piece 2511. The fixing strip 2521 contracts to form a conical surface 2522. The fixing strip 2521 has a convex surface 2523 and a concave surface 2524. The two ends of the convex surface 2523 in the width direction form guide strips 2525 in the radial direction.

[0044] The mating piece 2511 allows for better adhesion and mating with the surface layer 110 and the permeable layer 120. The fixing strip 2521 provides better mating with the hardened layer 130.

[0045] In this embodiment, the water guide channel includes a first sub-channel formed at the mating piece 2511, and all concave surfaces 2524 together form a second sub-channel. The first sub-channel and the second sub-channel are connected. Adjacent guide strips 2525 form a third sub-channel, and the third sub-channel is connected to the second sub-channel.

[0046] By setting up a first sub-channel, a second sub-channel, and a third sub-channel, the flow from the water surface layer 110 to below the permeable layer is better achieved.

[0047] Furthermore, when water is in the second sub-channel, it undergoes a hydration reaction with the hardening medium within the second sub-channel. At this time, the hardening medium on the outside of the seepage nail 250 has not yet come into contact with water, hence its lower density. After the hardening medium undergoes a hydration reaction, its volume increases, thus increasing the volume of the second sub-channel. Consequently, the axial angle between the fixing strip 2521 and the mating piece 2511 increases, better achieving the bonding between the fixing strip 2521 and the hardening layer 130, and improving the support stability of the seepage nail 250.

[0048] In this embodiment, the hardening medium is dry concrete mixture.

[0049] Dry concrete mixes have good water absorption and good rigidity after solidification, thus enabling the hardening of the ground.

[0050] In this embodiment, the permeable layer 120 is woven from polyethylene and polypropylene materials.

[0051] Polyethylene and polypropylene have poor water absorption, so the woven polyethylene and polypropylene materials have good water permeability, allowing water to penetrate the permeable layer more effectively.

[0052] In this embodiment, the waterproof layer 140 is made of polyvinyl chloride.

[0053] Polyvinyl chloride (PVC) has better water resistance, which can effectively retain water inside the hardened cavity.

[0054] Example 2

[0055] This embodiment provides a method for manufacturing the site hardening device in Embodiment 1, which includes the following steps:

[0056] Step S1: Use a mold to injection mold 250 drainage nails;

[0057] Step S2: Lay the waterproof layer 140, lay the hardening medium on the waterproof layer 140, then lay the seepage layer 120, and vertically insert the seepage nails 250 at the seepage layer 120.

[0058] Step S3: Lay a hardening medium on the permeable layer 120;

[0059] Step S4: Lay the surface layer 110 on the surface of the permeable layer 120.

[0060] The solution provided in this embodiment provides a better production site hardening device.

[0061] Example 3

[0062] This embodiment provides a method for using a site hardening device, which is implemented using the site hardening device in Embodiment 1, and includes the following steps:

[0063] Step S1: Use a mixture of 3:7 lime and soil to compact the ground to be laid to form a base;

[0064] Specifically, construction lines should be set up according to design requirements. The storefront must be flat and free of loose soil and voids. Areas affected by water damage must be compacted, free of debris and gravel, and reinforced with a 3:7 mixture of lime and soil before being sealed off.

[0065] Step S2: Lay the device body 100 on the base, with the waterproof layer 140 facing the ground;

[0066] Specifically, the device body 100 can be laid longitudinally or laterally, depending on the actual conditions of the road surface to be paved.

[0067] Step S3: Secure the device body 100 to the ground using rivets;

[0068] Specifically, the edge of the device body 100 is fixed to the ground with rivets, and the overlapping parts are also fixed with rivets.

[0069] Step S4: Pour water to soak the main body of the device 100, and wait for the main body of the device to air dry naturally.

[0070] Specifically, after the main body of the device is laid, it is watered evenly and thoroughly. After 12 hours, it is watered evenly again for curing, with a cycle of three days.

[0071] The solution provided in this embodiment can better integrate the device body 100 with the ground and ensure complete hydration reaction within the device body; thus, it can better achieve ground hardening.
