In the process of placing the first layer, two adjacent prefabricated retaining wall modules located in the same horizontal direction are made to abut against each other, and in the process of placing the second layer of prefabricated retaining wall modules upwards, the plug covers are plugged into the slots corresponding to the positions to connect the two adjacent prefabricated retaining wall modules located in the same vertical direction together, so that a plurality of interconnected prefabricated retaining wall modules together form a retaining wall; in the whole construction process, the installation of the prefabricated retaining wall modules is very simple and fast, and does not require too much manpower and equipment, and a continuous retaining wall can be built in a short time, thereby shortening the construction period and improving the efficiency of the whole construction process.

[0010] By adopting the above technical solution, the provision of the reinforcement portion improves the connection strength between the inner plate and the middle plate, and the provision of the convex portion improves the impact resistance of the outer plate.

[0011] Preferably, the length of the outer side plate is greater than that of the inner side plate, so that when the ends of two adjacent outer side plates located in the same transverse direction abut against each other, there is a certain distance between the ends of the two inner side plates.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a precast concrete component connection structure. Figure 1 and Figure 2 The concrete prefabricated component connection structure includes a plurality of prefabricated retaining wall modules that are interconnected to form a retaining wall. Two adjacent prefabricated retaining wall modules located in the same horizontal direction abut against each other. A slot 42 is provided on the bottom surface of the prefabricated retaining wall module. A plug cover 1 corresponding to the position of the slot 42 is detachably connected to the top surface of the prefabricated retaining wall module. The plug cover 1 is plugged into the slot 42 to connect two adjacent prefabricated retaining wall modules located in the same vertical direction.

[0034] Reference Figure 1 and Figure 3The prefabricated retaining wall module includes an outer plate 2, an inner plate 3 arranged parallel to the outer plate 2, and two middle plates 4 connected between the outer plate 2 and the inner plate 3. The two middle plates 4 are symmetrically arranged between the outer plate 2 and the inner plate 3; the outer plate 2, the inner plate 3 and the middle plates 4 are all formed by concrete pouring in the mold cavity to form a prefabricated retaining wall module.

[0035] The length of the outer plate 2 is greater than that of the inner plate 3, so that when the ends of two adjacent outer plates 2 located in the same horizontal direction abut against each other, there is a certain distance between the ends of the two inner plates 3; thereby, multiple prefabricated retaining wall modules can be arranged not only in a straight line but also in an arc shape, that is, when the ends of two adjacent inner plates 3 abut against each other, multiple prefabricated retaining wall modules are arranged in an arc shape.

[0036] Reference Figure 1 and Figure 3 In order to improve the connection strength between the inner plate 3 and the middle plate 4, a reinforcing portion 31 is integrally formed between the inner plate 3 and the middle plate 4; the two reinforcing portions 31 on the same prefabricated retaining wall module are respectively located on the side away from the two middle plates 4. At the same time, in order to improve the impact resistance of the outer plate 2, a convex portion 21 is integrally formed on the side of the outer plate 2 away from the inner plate 3.

[0037] Reference Figure 1 and Figure 3 The outer plate 2, the inner plate 3 and the two middle plates 4 together enclose a first filling space 5, and a second filling space 51 is formed between two adjacent prefabricated retaining wall modules located in the same horizontal direction; compared with solid concrete blocks, the setting of the first filling space 5 and the second filling space 51 can reduce the self-weight of the prefabricated retaining wall module and reduce the burden on the foundation and supporting structure; during the construction process, the first filling space 5 and the second filling space 51 can be filled with stones, which can increase the overall strength of the prefabricated retaining wall module.

[0038] Reference Figure 2 and Figure 3 In order to facilitate the crane to lift the prefabricated retaining wall module, two symmetrically arranged first handles 32 are pre-embedded on the side of the inner plate 3 away from the outer plate 2, and a second handle 41 is pre-embedded on the top surface of each middle plate 4; the arrangement of the first handle 32 and the second handle 41 enables the crane hook to lift the prefabricated retaining wall module from different angles, so as to facilitate the construction of the prefabricated retaining wall module. A drain port 6 is provided on the bottom surface of the middle plate 4 of the prefabricated retaining wall module at the lowest layer, and the drain port 6 can be connected to a drain pipe to drain the water in the prefabricated retaining wall module.

[0039] Reference Figure 2 and Figure 4The number of plug-in covers 1 is consistent with the number of second handles 41 and corresponds one to one. The plug-in cover 1 can be detachably connected to the second handle 41 at the corresponding position, and the slot 42 is provided on the bottom surface of the middle plate 4; covering the plug-in cover 1 on the second handle 41 can provide a certain degree of protection for the second handle 41; on the other hand, compared with the second handle 41, the shape of the plug-in cover 1 is more regular, which helps to plug the plug-in cover 1 into the slot 42.

[0040] Reference Figure 2 and Figure 4 The plug cover 1 is a hollow cover body with an opening at the bottom, and the plug cover 1 is a stainless steel cover with high hardness. A accommodating cavity 11 is opened inside the side wall of the plug cover 1, and a positioning member for positioning the plug cover 1 is arranged in the accommodating cavity 11. The positioning end of the positioning member is connected to the second handle 41 to position the plug cover 1 on the second handle 41; at the same time, in order to enable the plug cover 1 to be more stably positioned on the second handle 41, two positioning members are provided, and the two positioning members are symmetrically arranged.

[0041] Reference Figure 2 and Figure 4 The positioning member includes a spring 12 fixedly connected to the accommodating cavity 11, a stopper 13 fixedly connected to one end of the spring 12 close to the second handle 41, and a positioning block 14 fixedly connected to one end of the stopper 13 away from the spring 12; the stopper 13 is slidably connected to the accommodating cavity 11, and one end of the positioning block 14 away from the stopper 13 passes through the accommodating cavity 11, and a positioning groove 411 corresponding to the position of the positioning block 14 is provided on the second handle 41. A chamfer is provided at one end of the positioning block 14 away from the stopper 13. When the plug cover 1 is covered on the second handle 41, the chamfer abuts against the second handle 41, so that the stopper 13 compresses the spring 12. When the positioning block 14 corresponds to the position of the positioning groove 411, the spring 12 resets the positioning block 14, so that the positioning block 14 is inserted into the positioning groove 411, and the positioning of the plug cover 1 is completed.

[0042] Reference Figure 2 and Figure 4 , a limiting member is provided at the inner top of the plug cover 1, and the limiting end of the limiting member is connected to the second handle 41, so that the plug cover 1 cannot move vertically upward; the limiting member includes a limiting rod 15 rotatably connected to the inner top of the plug cover 1 and a limiting block 16 fixedly connected to the bottom end of the limiting rod 15; a limiting opening 412 corresponding to the position of the limiting block 16 is provided on the top surface of the second handle 41; the limiting block 16 and the limiting opening 412 are both set to be rectangular, and the cross-sectional area of ​​the limiting block 16 is smaller than the cross-sectional area of ​​the limiting opening 412. The limiting block 16 is rotated so that the direction of the limiting block 16 is consistent with the direction of the limiting opening 412. When the plug cover 1 is covered on the second handle 41, the limiting block 16 passes through the limiting opening 412, and then the limiting rod 15 is rotated so that the limiting block 16 is misaligned with the limiting opening 412, so that the plug cover 1 is limited on the second handle 41.

[0043] At the same time, in order to prevent the top end of the limit rod 15 from protruding from the top surface of the plug cover 1 and to minimize the influence of the limit rod 15 on the slot 42, the top end of the limit rod 15 is flush with the top surface of the plug cover 1, and a straight groove 151 is provided on the top surface of the limit rod 15, and the length direction of the straight groove 151 is consistent with the length direction of the limit block 16; the existence of the straight groove 151 allows construction personnel to use tools to rotate the limit rod 15, and the straight groove 151 also plays a certain marking role, and the construction personnel can judge the position of the limit block 16 by the direction of the straight groove 151.

[0044] The implementation principle of a concrete prefabricated component connection structure in an embodiment of the present application is: lay a good foundation, use a crane to arrange the prefabricated retaining wall modules layer by layer as required, and then, insert a drainage pipe into the drainage port 6 of the bottom layer of the prefabricated retaining wall module as required, and then fill the first filling space 5 and the second filling space 51 with stones to form a retaining wall.

[0045] Since traditional concrete retaining walls usually use stone or brick-concrete structures, they are prone to collapse if not handled properly; prefabricated retaining wall modules can be modularly designed according to project requirements, so that the shape and size of prefabricated retaining wall modules can be standardized, making the installation of prefabricated retaining wall modules very simple and fast, and without too much manpower and equipment, a continuous retaining wall can be built in a short time.
