Description

Technical Field

[0001] The utility model relates to the technical field of pre-buried water stop ring steel casings for precipitation wells, in particular to an assembled water stop ring steel casing. Background Art

[0002] Due to the rich groundwater resources in some areas, precipitation treatment is required during basement construction to prevent leakage. In the commonly used well point precipitation method, if the precipitation well is not properly sealed, it is easy to form an infiltration channel, which increases the difficulty and cost of maintenance. The use of sand-free permeable pipes and steel casing pre-buried technology can effectively prevent cracking and leakage of the basement floor and reduce the cost of later maintenance. This method does not affect the well point layout, shortens the construction period, and is safe, beautiful, and environmentally friendly in construction, meeting the green construction standards. At the same time, this technology can speed up the construction progress, reduce costs, and improve the quality of construction, and has broad application prospects.

[0003] In the process of using the above-mentioned sand-free permeable pipe and steel casing pre-embedded technology, it is necessary to use a water stop ring and a steel casing combination, and the upper and lower steel casings in the prior art are generally directly welded to the water stop ring, and during construction, the welded water stop ring steel casing combination is pre-embedded in the basement raft, which plays the role of internal and external water blocking and double insurance. In the above technical scheme, the upper and lower steel pipe sleeves are fixedly connected to the water stop ring by welding, which leads to the problem that after the combination is buried in the basement raft, if the upper steel casing is not flush with the ground, the height of the upper steel casing can no longer be adjusted, affecting the sealing effect of the entire precipitation well. In this regard, the utility model provides an assembled water stop ring steel casing to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0020] like Figure 1 As shown, an assembled water stop ring steel casing provided by an embodiment of the utility model comprises a water stop ring 1, and a preset through hole 9 is opened at the central position of the surface of the water stop ring 1, a lower steel casing 13 is fixedly connected to the surface of the water stop ring 1, and the lower steel casing 13 is fixedly connected to the water stop ring 1 by welding, and a blocking bolt can be fixedly connected to the inside of the preset through hole 9;

[0021] The surface of the water stop ring 1 is connected with an assembly ring 3, and a preset annular groove 4 is provided on the surface of the assembly ring 3. The interior of the preset annular groove 4 is slidably connected with an upper steel casing 2. The wall thickness of the upper steel casing 2 is the same as the width of the interior of the preset annular groove 4, that is, the upper steel casing 2 is tightly connected with the assembly ring 3;

[0022] A plurality of fixed thread sleeves 7 are connected at equal distances inside the upper steel casing 2, and a fixed thread rod 6 is meshedly connected inside the fixed thread sleeve 7, and a plurality of preset thread grooves 8 are opened at equal distances on the surface of the assembly ring 3, and the outer diameter of the fixed thread rod 6, the inner diameter of the fixed thread sleeve 7 and the inner diameter of the preset thread groove 8 are all the same, and the fixed thread rod 6, the fixed thread sleeve 7 and the preset thread groove 8 are on the same axis;

[0023] A twist handle 5 is installed at one end of the fixed threaded rod 6, and the surface of the twist handle 5 is provided with anti-slip textures.

[0024] In one embodiment of the utility model, when the upper steel casing 2 is stably assembled on the water stop ring 1, firstly, one end of the upper steel casing 2 provided with a fixed threaded sleeve 7 is directly inserted into the preset annular groove 4 opened on the surface of the assembly ring 3, and then, the position of the upper steel casing 2 is adjusted inside the preset annular groove 4, so that the several fixed threaded sleeves 7 provided inside the upper steel casing 2 and the several preset threaded grooves 8 opened on the surface of the assembly ring 3 can be on the same axis, and then the staff rotates several twist handles 5, and the twist handles 5 drive the fixed threaded rod 6 to rotate until it is turned into the preset threaded groove 8 opened on the surface of the assembly ring 3, so as to firmly connect the upper steel casing 2 and the assembly ring 3 together. Since the upper steel casing 2 and the preset annular groove 4 are in a tightly connected state, the upper steel casing 2 has good sealing performance with the assembly ring 3 and the water stop ring 1;

[0025] It can be understood that when the upper steel casing 2 is fixed on the assembly ring 3 by using the fixed threaded rod 6, the fixed threaded sleeve 7 and the preset threaded groove 8, the height of the assembly ring 3 inside the preset annular groove 4 can be adjusted according to actual construction requirements, so that the overall height of the upper steel casing 2, the assembly ring 3 and the water stop ring 1 can meet the construction requirements;

[0026] After the water stop ring 1 and the upper steel casing 2 are pre-buried, if the height of the upper steel casing 2 needs to be adjusted according to the actual situation, it is only necessary to screw out a plurality of fixed threaded rods 6 from the inside of the preset threaded groove 8, and then fine-tune the height of the upper steel casing 2 inside the preset annular groove 4;

[0027] Through the above technical scheme, the upper steel casing 2 can be stably assembled with the water stop ring 1 in a detachable connection manner, and after the entire water stop ring steel pipe sleeve assembly is pre-buried inside the building, the height of the upper steel casing 2 can still be fine-tuned according to actual construction requirements, so that the water stop ring steel pipe sleeve assembly can fully adapt to the installation requirements, thereby improving the practicality of the assembled water stop ring steel casing.

The sealant injection hole 12 is sealed and connected to a sealing plug 11 through the internal fixing thread, and the interior of the sealant injection hole 12 is connected to the interior of the preset annular groove 4.

[0029] In this embodiment, in order to ensure high sealing performance between the upper steel casing 2 and the assembly ring 3, after the upper steel casing 2 and the assembly ring 3 are fixedly connected together, the staff can also inject sealant into the interior of the preset annular groove 4 through the sealant injection hole 12, and make the sealant fill the interior of the preset annular groove 4, thereby improving the sealing between the upper steel casing 2 and the assembly ring 3, and after injecting appropriate sealant, the sealing screw plug 11 can also be turned into the interior of the sealant injection hole 12 to block the sealant injection hole 12 to prevent the sealant from leaking.

[0030] Preferably, a nut receiving groove 10 is provided on the surface of the assembly ring 3, and the shape of the nut receiving groove 10 is adapted to the shape of the nut of the sealing screw plug 11, so that after the sealing screw plug 11 is completely rotated into the interior of the sealant injection hole 12, the nut of the sealing screw plug 11 can be directly embedded in the interior of the nut receiving groove 10 to ensure that the outer surface of the assembly ring 3 is in a completely flat state.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
