Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tie stones, in particular to a prefabricated tie stone with a water filtering function. Background Art
[0002] Retaining walls are widely used in water conservancy, municipal administration, transportation, ports and other engineering constructions. They are mainly used to support natural or artificial fill slopes to maintain soil stability. In order to prevent water accumulation behind the wall from forming hydrostatic pressure, drainage measures should be set up for retaining walls. At present, drainage pipes are generally used for drainage of retaining walls. In order to prevent pipe bursts, a graded crushed stone filter layer should be set up behind the drainage pipes.
[0003] During construction, the drainage holes are usually covered with geotextiles, then wrapped with graded sand, and finally wrapped with graded gravel on the outermost layer; some geotextiles are directly wrapped with graded sand and gravel and piled at the drainage pipe. This traditional construction method often has many disadvantages: first, construction workers do not have enough understanding of the importance of the filter layer, and it is difficult to control the construction quality of the filter layer; second, the graded gravel in the filter layer is not convenient to construct on site, and a part of the graded gravel needs to be reserved when filling the earthwork; third, it is difficult for the filter layer to meet the design requirements during on-site construction, and the "soil filtering" function is not fully exerted; fourth, when the seepage is large, the graded gravel will be dispersed by the water flow, and the sand will block the drainage holes and cannot be drained. There are many defects and problems in the traditional construction of the filter layer, which affects the stability of the retaining wall and brings serious safety hazards. Therefore, a prefabricated tie stone with water filtering function is needed. Summary of the invention
[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a prefabricated tie stone with a water filtering function to solve the numerous defects and problems in the existing anti-filtration layer construction, which affects the stability of the retaining wall and brings serious safety hazards.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A prefabricated tie stone with a water filtering function comprises a prefabricated tie stone, wherein water inlet holes and drainage holes are respectively opened on both sides of the prefabricated tie stone, and a slot is opened on the inner side of the prefabricated tie stone; a water filter sheet, wherein the water filter sheet is installed on the inner side of the slot; and a prefabricated cover plate, wherein the prefabricated cover plate is installed on the top surface of the prefabricated tie stone, thereby utilizing prefabricated assembly technology to improve the construction speed of retaining walls.
[0007] Furthermore, a positioning hole is opened on the top surface of the prefabricated tie stone, and the prefabricated cover plate is connected to the positioning hole by a positioning steel bar, so that the connection between the prefabricated cover plate and the prefabricated tie stone is firm and stable to avoid slippage.
[0008] Furthermore, the water filter sheet is arranged by double-sided steel wire mesh with geotextile wrapped in the middle, thereby reducing water seepage and preventing sand from blocking the drainage holes.
[0009] Furthermore, the prefabricated tie stones adopt a reinforced concrete structure, so that the prefabricated components have sufficient strength to not only drain water but also have tie stone functions.
[0010] Furthermore, the inner side of the water filter plate is filled with graded crushed stones, thereby facilitating construction and improving construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
