Description

TECHNICAL FIELD

[0001] The application relates to the technical field of building engineering, and in particular to a precast diaphragm wall splicing interface impurity blocking structure. BACKGROUND

[0002] The diaphragm wall (also known as the underground continuous wall) is a continuous wall body constructed for the purpose of retaining soil and water and bearing during the excavation of a foundation pit. The diaphragm wall is usually made of reinforced concrete and is constructed in sections, and the sections are connected into a whole through a specific mode (such as a locking pipe or an I-beam). The diaphragm wall has the advantages of large wall rigidity, good integrity and good water stopping effect, and is suitable for various geological conditions and complex construction environments. At the same time, since the diaphragm wall is constructed on the ground, the construction difficulty and risk can be greatly reduced. During the construction process, the diaphragm wall needs to be matched with a corresponding support system to maintain the stability of the foundation pit. After the excavation of the foundation pit is completed, the diaphragm wall can be used as the outer wall of the basement or as a temporary soil retaining structure during the excavation of the foundation pit.

[0003] In the prior art, a precast diaphragm wall structure is provided, a groove is formed on one side of the precast diaphragm wall, and a flange is extended on the other side. During construction, a groove is excavated on the ground, and then the groove and the flange of the precast diaphragm wall are spliced by a crane to form a whole diaphragm wall. However, since the bottom of the excavated groove is filled with mud and other impurities after excavation, the mud and other impurities may remain in the groove of the precast diaphragm wall during splicing, resulting in unevenness of the bottom of the precast diaphragm wall and poor anti-flow effect in the later stage. Therefore, the application provides a precast diaphragm wall splicing interface impurity blocking structure. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies in the prior art, the application aims to provide a precast diaphragm wall splicing interface impurity blocking structure to solve the problem of unevenness of the bottom of the spliced diaphragm wall caused by mud in the excavated groove.

[0005] The above-mentioned purpose of the application is achieved by the following technical scheme: a precast diaphragm wall splicing interface impurity blocking structure comprises a wall body, a groove is formed on one side of the wall body, a flange matched with the groove is extended on the other side of the wall body, flexible rubber baffles are arranged on both sides in the groove and fixedly connected to the wall body, and a lifting structure is arranged on the upper end of the wall body.

[0006] By adopting the above-mentioned technical scheme, when splicing, the wall body is placed in the excavated groove through the lifting structure. Since the flexible rubber baffles in the groove of the wall body are combined, the mud in the excavated groove cannot enter the groove. When the flange on the other wall body is butted into the groove, the flexible rubber baffles in the groove are squeezed, so that the flange can normally enter the groove, and the splicing of the diaphragm wall is completed.

[0007] Further, the upper end of the flexible rubber baffle on both sides is inclined from outside to inside, and the bottom of the flange is inclined from outside to inside.

[0008] By adopting the above technical scheme, considering that the groove and the flange may be skewed when splicing by the crane, the upper end of the flexible rubber baffle on both sides is inclined, which can provide guidance for the flange during splicing.

[0009] Further, the upper end of the flexible rubber baffle on both sides is inclined from outside to inside, and the bottom of the flange is inclined from outside to inside.

[0010] By adopting the above technical scheme, considering that the groove and the flange may be skewed when splicing by the crane, the upper end of the flexible rubber baffle on both sides is inclined, which can provide guidance for the flange during splicing.

[0011] Further, the wall is provided with a reinforcing groove on both sides of the groove, and a reinforcing strip is fixedly arranged on one side of the wall extension flange.

[0012] By adopting the above technical scheme, considering that there may be a slight gap inside after the groove and the flange are spliced, which may cause the wall to tilt, the reinforcing groove and the reinforcing strip can be spliced to avoid the above problems.

[0013] Further, the lifting structure comprises a pair of lifting rings, a pair of the lifting rings are fixedly provided with studs at the bottom, the studs extend out rotating blocks at the bottom, the rotating blocks are provided with through holes in the middle, the through holes are rotatably provided with rotating rods, and the rotating rods are rotatably provided with fixed plates fixedly connected to the wall at both ends.

[0014] By adopting the above technical scheme, since the wall splicing requires a certain degree of accuracy, a pair of lifting rings need to be arranged, and the lifting rings are rotatably connected to the wall, so that the lifting rings can be placed on the wall after splicing, avoiding the lifting rings standing up all the time.

[0015] Further, the stud is sleeved with a rotating sleeve, and the rotating sleeve and the stud are threadedly connected.

[0016] By adopting the above technical scheme, considering that the lifting ring is rotatably connected to the wall, before lifting, the worker needs to stand up the lifting ring, and wait for the crane to hook the lifting ring, which may have safety hazards. Therefore, in the present application, a rotating sleeve is arranged on the stud, and before lifting, the rotating sleeve is moved to the lowermost end to cover the fixed plate, so that the lifting ring cannot be rotated, thereby maintaining the standing state, so that the crane can directly lift.

[0017] Further, the rotating sleeve at the bottom is provided with a placing groove opened at the upper end of the wall body.

[0018] By adopting the above technical scheme, in order to not affect the subsequent construction after the wall body is spliced, the placing groove is opened, the rotating sleeve on the stud is upwardly rotated, the lifting ring is restored to rotate, and the lifting ring is placed in the rotating groove, so that the lifting ring does not affect the subsequent construction.

[0019] Further, a pair of the lifting rings are respectively arranged at both sides of the upper end of the wall body.

[0020] By adopting the above technical scheme, the wall body can be better spliced.

[0021] In summary, the present application has at least one of the following beneficial technical effects:

[0022] 1. When splicing, the wall body is placed in the groove by the lifting structure, because the flexible rubber baffle in the wall body groove is combined, the sand in the groove cannot enter the groove, and when the flange on the other wall body is butted into the groove, because of the flexible rubber baffle in the groove, it will be extruded, so that the flange will normally enter the groove, and the splicing of the continuous wall is completed.

[0023] 2. Considering that when the crane is spliced, if the worker accidentally operates incorrectly when lowering, the wall body will fall too fast, which will excessively extrude the flexible rubber baffle, which may cause the flexible rubber baffle to separate from the wall body, and cause the bottom of the wall body to be uneven after splicing is completed, therefore, the setting of the rubber fixing plate will pull the rubber fixing plate when the flexible rubber baffle is pulled downward, so as to avoid the flexible rubber baffle in the groove from being separated.

[0024] 3. The rotating sleeve is arranged on the stud, before lifting, the rotating sleeve is moved to the lowermost end, the fixing plate is sleeved, so that the lifting ring cannot rotate, and the standing state is maintained. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0028] The application will be further described in detail below with reference to the accompanying drawings.

[0029] Embodiment, refer to Figure 1 Figure 2 A prefabricated diaphragm wall splicing interface impurity blocking structure, comprising a wall body 1, a groove 11 is formed on one side of the wall body 1, a flange 12 is extended on the other side of the wall body 1 and matches the groove 11, flexible rubber baffle plates 13 are arranged on both sides of the groove 11 and fixedly connected to the wall body 1, and a lifting structure is arranged on the upper end of the wall body 1; when splicing, the wall body 1 is placed in a groove through the lifting structure, and since the flexible rubber baffle plates 13 in the groove 11 are combined, the silt in the groove cannot enter the groove 11, and when the flange 12 on the other wall body 1 is butted into the groove 11, the flexible rubber baffle plates 13 in the groove 11 are extruded, so that the flange 12 can normally enter the groove 11, and the splicing of the diaphragm wall is completed.

[0030] In the embodiment, the upper ends of the flexible rubber baffle plates 13 on both sides are inclined from outside to inside, and the bottom of the flange 12 is inclined from outside to inside; considering that the groove 11 and the flange 12 may be skewed when splicing by a crane, the upper ends of the flexible rubber baffle plates 13 on both sides are formed into inclined surfaces, which can provide guidance when the flange 12 is spliced.

[0031] In the embodiment, rubber reinforcing plates 14 are extended to both ends of the flexible rubber baffle plates 13 on both sides, and the bottom of the rubber reinforcing plate 14 is fixedly connected to the wall body 1; considering that if the wall body 1 falls too fast due to accidental operation of a worker when splicing by a crane, the flexible rubber baffle plates 13 will be excessively extruded, which may cause the flexible rubber baffle plates 13 to be separated from the wall body 1 and the bottom of the wall body 1 to be uneven after splicing is completed, the rubber reinforcing plate 24 is arranged, and when the flexible rubber baffle plates 13 are pulled downward, the rubber reinforcing plate 24 is pulled, so that the flexible rubber baffle plates 13 in the groove 11 are prevented from being separated.

[0032] In the embodiment, reinforcing grooves 15 are formed on both sides of the groove 11 of the wall body 1, and reinforcing strips 16 are fixedly arranged on one side of the extended flange 12 of the wall body 1; considering that there may be a slight gap inside after the groove 11 and the flange 12 are spliced, which may cause the wall body 1 to be inclined, and the reinforcing grooves 15 and the reinforcing strips 16 can be spliced to avoid the above problems.

[0033] ​In this embodiment, the hoisting structure comprises a pair of lifting rings 2, the bottom of the pair of lifting rings 2 is fixedly provided with a stud 21, the bottom of the stud 21 extends out of a rotating block 22, a through hole is formed in the middle of the rotating block 22, a rotating rod 23 is rotatably arranged in the through hole, and the two ends of the rotating rod 23 are rotatably provided with fixed plates 24 fixedly connected to the wall body 1. Since the wall body 1 needs a certain accuracy for splicing, a pair of lifting rings 2 need to be arranged, and the lifting rings 2 are rotatably connected to the wall body 1. After splicing, the lifting rings 2 can be rotatably placed on the wall body 1, so as to avoid the lifting rings 2 from being always erected. A rotating sleeve 25 is sleeved on the stud 21, and the rotating sleeve 25 is threadedly connected with the stud 21. Considering that the lifting rings 2 are rotatably connected to the wall body, before hoisting, the workers need to erect the lifting rings 2, and wait for the crane to hook the lifting rings 2. At this time, there may be a safety hazard. Therefore, in this application, the rotating sleeve 25 is arranged on the stud 21, and before hoisting, the rotating sleeve 25 is moved to the lowermost end to sleeve the fixed plate 24, so that the lifting rings 2 cannot rotate, thereby maintaining the erected state, and the crane can directly hoist.

[0034] In this embodiment, the bottom of the rotating sleeve 25 is provided with a placing groove 3 formed in the upper end of the wall body 1. In order to avoid the lifting rings 2 affecting the subsequent construction after the wall body 1 is spliced, the placing groove 3 is arranged, the rotating sleeve 25 on the stud 21 is rotated upward, the lifting rings 2 are restored to rotate, and the lifting rings 2 are rotatably placed in the placing groove 3, so as to ensure that the lifting rings 2 do not affect the subsequent construction, and the two lifting rings 2 are arranged on the two sides of the upper end of the wall body 1, so as to better splice the wall body 1.

[0035] Specific implementation process:

[0036] When splicing, after the wall body 1 is placed in the groove by the hoisting structure, since the flexible rubber baffle 13 in the groove 11 is combined, the silt in the groove cannot enter the groove 11, and when the flange 12 on the other wall body 1 is butted into the groove 11, the flexible rubber baffle 13 in the groove 11 is extruded, so that the flange 12 can normally enter the groove 11, and the splicing of the ground-connected wall is completed. Considering that when the crane is spliced, if the workers accidentally operate incorrectly when lowering, the wall body 1 may fall too fast, which may excessively extrude the flexible rubber baffle 13, and the flexible rubber baffle 13 may be separated from the wall body 1, which may cause the bottom of the wall body 1 to be uneven after splicing is completed. Therefore, the rubber fixed plate 24 is arranged, and when the flexible rubber baffle 13 is pulled downward, the rubber fixed plate 24 is pulled, so as to avoid the flexible rubber baffle 13 in the groove 11 from being separated.

[0037] The embodiments of the specific implementation mode are preferred embodiments of the application, and are not limited to the protection scope of the application. Therefore, any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
