[0001] The invention discloses a settlement road connection mechanism and a construction method thereof, belonging to the technical field of road construction. Background Art

[0002] With the continuous development of the construction industry, the requirements and aesthetics for semi-basements have increased. There are many basements that are used as roads. There is a small degree of settlement at the junction of the basement structure and the outdoors, which can be repaired. The cost of the stone layer is generally determined by its size. The larger the single piece, the higher the price. As the settlement gradually increases, it is easy for the road base to be pulled and broken, resulting in the stone pavement being cracked. As time goes by, settlement continues to occur, repeated fractures and repairs occur. The repair cost is high and it is difficult to avoid subsequent settlement. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a settlement road connection mechanism and a construction method thereof, so as to solve the problem that as the settlement amplitude gradually increases, the road base layer is prone to breaking, which leads to the stone pavement being cracked, and as the settlement continues to occur over time, repeated fractures and repairs occur, the repair cost is high and it is difficult to avoid subsequent settlement.

[0004] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0005] A settlement road connection mechanism, comprising: a first structural layer, a second structural layer, and a plurality of connection mechanisms arranged at intervals between the first structural layer and the second structural layer;

[0006] The connecting mechanism includes a support, a connecting ring movably installed on the side of the support, and a connecting hook located on the side of the connecting ring away from the support. The support is inserted and fixed in the first structural layer, the connecting hook is fixed in the second structural layer, the connecting ring is slidably installed on the side of the support, and the connecting ring is used to connect the support and the connecting hook.

[0007] A construction method for a settlement road connection mechanism, the steps comprising:

[0008] S1, when the basement structure is completed, the basement side wall is backfilled to form a soft soil layer;

[0009] S2, laying of road base over basement structure and soft soil layer;

[0010] S3, burying the supports with connecting rings at intervals in the road base, and sealing and protecting the connection parts between the supports and the connecting rings;

[0011] S4, laying a mortar layer on top of the road base;

[0012] S5, a connecting hook is implanted on the stone layer, and the stone layer is laid on the mortar layer, and the stone slab with the connecting hook implanted is laid on the mortar layer on the soft soil layer;

[0013] S6, pull and fix the connecting ring above the basement structure and the connecting hook above the soft soil layer.

[0014] The beneficial effects of the present invention are:

[0015] The present invention sets a support on the first structural layer, sets a connecting hook on the stone layer of the second structural layer, and sets a connecting ring between the support and the connecting hook so that a stable connection state with a buffer space can be achieved. Since the connecting ring has a movable space on the support, when the first structural layer and the second structural layer sink, local adjustment can be performed on the support through the connecting ring. As the sinking increases, the connecting ring can be pulled by the connecting hook. Under the setting of several connecting mechanisms, a force system is formed between the first structural layer and the second structural layer, so that the two are in a state of mutual force and there is a certain redundant adjustment space. When the first structural layer sinks, the stone layer in the second structural layer can obtain a certain adjustment space through the connecting hook, and when there is no adjustment space, the sinking can be slowed down by tension control, which can effectively reduce the cracking of the stone slab, thereby reducing the repair cost caused by road sinking, and can also effectively resist the sinking of the road.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0026] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The research is conducted using the characteristics of structural stress and the functional appearance of the building. Conventional road cracking only analyzes the shrinkage of the road, and the problem cannot be solved when encountering roads with expansion and contraction and bending deformation. The original stone road construction will cause the road base to break due to settlement, resulting in the stone being torn. As time goes by, settlement continues to occur, repeated fractures and repairs will occur. A small amount of settlement occurs at the junction of the basement structure and the outdoors, which can be repaired. The cost of the stone layer is generally determined by its size. The larger the single piece, the higher the price. As the settlement amplitude gradually increases, it is easy for the road base to be pulled and broken, resulting in the stone pavement being torn. As time goes by, settlement continues to occur, repeated fractures and repairs will occur. The repair cost is high and it is difficult to avoid subsequent settlement. Therefore, in order to solve the above-mentioned technical problems, the present invention discloses the following technical solutions:

[0029] Reference Figure 1-8 As shown, a settlement road connection mechanism includes a first structural layer 1, a second structural layer 2, and a plurality of connection mechanisms 3 arranged between the first structural layer 1 and the second structural layer 2 at intervals, wherein the first structural layer 1 and the second structural layer 2 are composed of a road base layer 11, a mortar layer 12, and a stone layer 13 from bottom to top, and the first structural layer 1 also includes a hard structural layer 11, and the hard structural layer 11 is located below the road base layer 11, and the second structural layer 2 also includes a soft soil layer 21, and the soft soil layer 21 is located below the road base layer 11.

[0030] The connecting mechanism 3 includes a support 31, a connecting ring 32 movably installed on the side of the support 31, and a connecting hook 33 located on the side of the connecting ring 32 away from the support 31. The support 31 is inserted and fixed in the first structural layer 1, the connecting hook 33 is fixedly installed in the second structural layer 2, the connecting ring 32 is slidably installed on the side of the support 31, and the connecting ring 32 is used to connect the support 31 and the connecting hook 33.

[0031] In order to make the first structural layer 1 have several points of force, several supports 31 are provided. The supports 31 are composed of a horizontal extension part 311 and a vertical part 312. The horizontal extension part 311 and the vertical part 312 are welded and fixed together. The vertical part 312 is inserted and fixed in the first structural layer 1. The vertical part 312 needs to penetrate the road base 11, the mortar layer 12, and the stone layer 13, while the upper part of the horizontal extension part 311 is flush with the upper surface of the stone layer 13 and is located inside the stone layer 13 as a whole. A groove is reserved in the mortar layer 12 of the stone layer 13, and the groove is located directly below the horizontal extension part 311 to facilitate the movement of the connecting ring 32 and the connection with the connecting hook 33. The width of the support 31 is W, and the interval between two adjacent supports 31 is 3W / 5. Among them, one support 31 is set in each connecting mechanism 3, so the setting interval between two adjacent connecting mechanisms 3 is 3W / 5. In this embodiment, the width W of the support 31 is 50cm, and the interval between two adjacent supports 31 is 30cm.

[0032] In order to further strengthen the connection between the support 31 and each layer, a plurality of through grooves 3121 are arranged at intervals on the side of the vertical portion 312. The through grooves 3121 can be penetrated by the mortar layer 12 of the road base layer 11 and filled by the stone layer 13, so that the installation of the support 31 and the first structural layer 1 is in a highly stable state. In this embodiment, the support 31 is made of steel material.

[0033] In order to achieve a stable connection state with buffer space between the support 31 and the connecting hook 33, a connecting ring 32 is set between the two. The connecting ring 32 consists of a guide ball 321, a ring body 322 and a rod 323 connecting the guide ball 321 and the ring body 322. The guide ball 321 is fixedly connected to the ring body 322 and the rod 323 by welding. The guide ball 321 is slidably connected to the support 31, and the ring body 322 is buckled with the connecting hook 33 to connect the first structural layer 1 and the second structural layer 2, so that the two are in a state of mutual force and there is a certain redundant adjustment space. When the first structural layer 1 sinks, the stone layer 13 in the second structural layer 2 can obtain a certain adjustment space through the connecting hook 33, and when there is no adjustment space, the sinking of the first structural layer 1 can be slowed down by tension control, which can effectively reduce the occurrence of cracks.

[0034] In order to facilitate the installation of the connecting ring 32, a guide groove 313 is provided directly below the horizontal extension portion 311, and the guide groove 313 matches the guide ball 321. In this embodiment, the entrance of the guide groove 313 is provided on a side of the vertical portion 312 close to the horizontal extension portion 311, extending toward the horizontal extension portion 311 in an arc shape, and is provided horizontally at the horizontal extension portion 311. In order to prevent the guide ball 321 from easily detaching, a protrusion 3131 is provided below the guide groove 313 in the horizontal extension portion 311, which can block the guide ball 321 during the normal movement. The horizontal extension portion 311 is unilaterally through, and the through transverse groove is mainly for facilitating the installation of the connecting ring 32, so that the connecting ring 32 can move horizontally in the guide groove 313. When the connection with the connecting hook 33 cannot be completed at the current position, the connecting ring 32 can be moved horizontally in the guide groove 313 to reach a position where it can be connected with the connecting hook 33. In this embodiment, the lock handle 3312 and the fastener 3313 in the connecting hook 33 are made of high-strength steel with a yield strength of more than 1370MPa (140kgf / mm) and a tensile strength of 1620MPa, which can continuously withstand high-intensity pulling force. The hook sleeve 3311 and the connecting ring 32 are made of steel material. Furthermore, when the tensile force between the two exceeds the material bearing range of the connecting ring 32, the connecting ring 32 can be deformed, and its deformation space can always maintain the connection state between the connecting ring 32 and the connecting hook 33, and it is not easy to break, which can further enhance the stability against settlement.

[0035] In order to realize the closed-loop connection between the connecting ring 32 and the connecting hook 33, the connecting hook 33 is composed of a buckling part 331 and a main connecting rod 332. The buckling part 331 includes a hook sleeve 3311, a locking handle 3312, and a fastener 3313. A channel is provided inside the hook sleeve 3311, and the locking handle 3312 is movably installed in the channel. The fastener 3313 is embedded in the side of the hook sleeve 3311, and the fastener 3313 is used to clamp and constrain the freedom of the locking handle 3312. The hook sleeve 3311 is welded to the main connecting rod 332. When the locking handle 3312 passes through the connecting ring 32, it is inserted into the hook sleeve 3311 and constrained by the fastener 3313 to prevent it from actively detaching without operation.

[0036] The fastener 3313 is composed of a button a1 with a spring, and a hook s2 arranged on one side of the button a1, wherein the hook a2 is fixedly connected to the button a1, and the hook a2 is located on one side of the lock handle 3312, and the protrusion above the hook a2 is in accordance with the tooth groove on the lock handle 3312, and the lock handle 3312 can be locked and kept in a fixed state by inserting the protrusion into the tooth groove on the side of the lock handle 3312, thereby completing the closed state of the connection hook 33 that has completed the closed loop connection with the connection ring 32. In addition, a slot is provided on the lock handle 3312, and when in use, the lock handle 3312 can be operated by inserting an auxiliary rod (not shown in the figure) into the slot, and a clamping block a is provided on the outer side of the rear end of the lock handle 3312, which is used to constrain the lock handle 3312 in the hook sleeve 3311 to prevent it from slipping out.

[0037] In this embodiment, the main connecting rod 332 is inserted and fixed in the stone layer 13, and an auxiliary connecting rod 333 can be further set on the side of the main connecting rod 332. In this embodiment, the auxiliary connecting rod 333 is welded to the side of the main connecting rod 332. In other embodiments, it can be screwed into the main connecting rod 332 by thread or directly penetrated into the main connecting rod 332. The auxiliary connecting rod 333 forms an angle with the main connecting rod 332, which can enhance the tensile coefficient of the main connecting rod 332. In this embodiment, the main connecting rod 332 adopts a chemical anchor bolt, which is a high-strength anchor bolt with vinyl resin as the main raw material, and was called a chemical drug bolt in the early days. The chemical anchor bolt is a new type of anchor bolt that appeared after the expansion anchor bolt. It is a composite part that uses a special chemical adhesive to fix the screw rod to the drilled hole of the concrete base material to achieve anchoring of the fixing part.

[0038] It should be emphasized that the support 31 is parallel to and in close contact with the stone layer 13 after installation.

[0039] A construction method for a settlement road connection mechanism, the steps comprising:

[0040] S1, when the basement structure is completed, the basement side wall is backfilled to form a soft soil layer;

[0041] S2, laying the road base 11 above the basement structure and the soft soil layer;

[0042] S3, burying the supports 31 with the connecting rings 32 in the road base 11 at intervals, and sealing the connection parts between the supports 31 and the connecting rings 32 for protection;

[0043] S4, laying a mortar layer 12 on the road base 11;

[0044] S5, implanting the connecting hook 33 on the stone layer 13, and laying the stone layer 13 on the mortar layer 12, and the stone slab implanted with the connecting hook 33 is laid on the mortar layer 12 on the soft soil layer 14;

[0045] S6, the connection ring 32 above the basement structure and the connection hook 33 above the soft soil layer 14 are pulled together and fixed.

[0046] In step S3, the spacing between the supports 31 on the road base 11 is 3W / 5. In the present embodiment, the width of the supports 31 is W, and the spacing between two adjacent supports 31 is 3W / 5. One support 31 is provided in each connecting mechanism 3, so the spacing between two adjacent connecting mechanisms 3 is 3W / 5. In the present embodiment, the width W of the supports 31 is 50 cm, and the spacing between two adjacent supports 31 is 30 cm.

[0047] In addition, the slide rail and the connecting ring 32 on the support 31 are sealed for protection. In this embodiment, a plastic film is used for wrapping to avoid blockage during the subsequent laying of the mortar layer 12. At the same time, before entering the next step, step S31 needs to be executed to reserve a channel directly below the support 31 to facilitate the subsequent pulling and connection with the connecting hook 33.

[0048] In step S5, the straight rod part of the connecting hook 33 is installed with chemical bolts, and the connecting hook 33 is implanted on the stone layer 13, and needs to be placed for 6-10 hours to allow the chemical bolts to stabilize before paving, and then pull-joining is performed after paving is completed. In this embodiment, preferably, the installed connecting hook 33 is placed for 6 hours.

[0049] Furthermore, the depth of the connecting hook 33 implanted in the stone is in the range of 5-8 cm, which can be appropriately adjusted according to the actual thickness of the stone, and is usually not less than 5 cm. If the depth of the implantation in the stone is less than 5 cm, the force it bears is relatively limited. When the stone thickness is average and the depth of the implantation in the stone exceeds 8 cm, the side stone is prone to breakage. In this embodiment, the depth of the implantation of the connecting hook 33 in the stone is 5 cm.

[0050] Before step S6, when the stone layer 13 is placed, a 15-20 cm space needs to be reserved between the support 31 to facilitate the connection operation between the connecting ring 32 and the connecting hook 33. In this embodiment, a 15 cm operating space is reserved between the stone layer 13 and the support 31 after the stone layer 13 is placed.

[0051] After step S6 , the stone layer 13 needs to be pushed flatly toward the support 31 to fit the support 31 and keep the stone layer 13 in the same plane and in a fit state as much as possible.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
