Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to a prefabricated water channel anti-deformation connection structure. Background Art
[0002] Drainage channels are usually constructed by connecting multiple sections of prefabricated channels. In the prefabricated channel connection structure, thickened waterproof membrane layers and additional waterproof membrane layers are generally set at the joints to improve the waterproof performance by utilizing the hydrophobicity and thickness of the waterproof membrane. However, when the connection gaps between the prefabricated channels are deformed due to uneven settlement, the waterproof membrane will break, and leakage or poor drainage due to height difference will occur at the joints. Especially in cold areas, when the joints of prefabricated channels are repeatedly frozen and heaved after winter, the toughness of the waterproof membrane will decrease and the brittleness will increase, which is very easy to cause fracture, resulting in leakage or poor drainage at the joints of the drainage channels. When the connection structure of the prefabricated channels on both sides is buried with water-stop steel plates at the joints, leakage at the joints can be effectively prevented. However, when the connection gaps between the prefabricated channels are deformed due to uneven settlement, the water-stop steel plates are prone to detachment from the concrete structure, and leakage or poor drainage due to height difference will still occur, especially in cold areas that are more affected by repeated freezing and heaving in winter. Therefore, how to prevent dislocation and deformation at the joints of each section of the prefabricated water channel from being subjected to uneven settlement, and avoid leakage or poor drainage due to height differences is a technical problem that urgently needs to be solved in this field.

It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.
[0023] Please refer to Figures 1 to 4 The embodiment of the utility model provides a prefabricated water channel anti-deformation connection structure 100, including a plurality of linear steel bars 111 embedded in the wall thickness of a prefabricated water channel 110 on one side of a joint, wherein the linear steel bars 111 are exposed at the end face of the prefabricated water channel 110 on this side, and a plurality of linear embedded sleeves 112 corresponding to the linear steel bars 111 are embedded in the wall thickness of the prefabricated water channel 110 on the other side of the joint, wherein the linear embedded sleeves 112 do not expose the end face of the prefabricated water channel 110 on this side, and the prefabricated water channels 110 on both sides of the joint are connected by inserting the linear steel bars 111 into the linear embedded sleeves 112, wherein the linear steel bars 111 are telescopically inserted and connected in the linear embedded sleeves 112, and an asphalt mastic body 113 is filled at the joint of the prefabricated water channel 110. The asphalt mortar is preferably thickened and vibrated to ensure that there is no gap in the mortar at the joint and the filling is dense.

When the two adjacent sections of prefabricated water channels 110 are in the joint, the prefabricated water channels 110 are connected by a linear steel bar 111 and a linear embedded sleeve 112 which can be retracted and inserted, so that the prefabricated water channels 110 on both sides of the joint are kept on the same horizontal plane and are displaced in the vertical direction. When horizontal gaps occur at the joints, the prefabricated water channels 110 on both sides of the joints maintain a telescopic connection with the linear embedded sleeves 112 through the linear steel bars 111. Combined with the soft connection of the asphalt mastic body 113 and the resulting telescopic deformation, the joints will not crack or break, thus avoiding the problem of water leakage at the joints. This can overcome the problem of repeated frost heaving at the joints caused by low temperatures and cold waves when constructing drainage channels in cold regions using prefabricated water channels 110, resulting in uneven settlement and misalignment of the prefabricated water channels 110 on both sides of the joints.
