Description

Technical Field

[0001] The invention relates to the field of highway auxiliary drainage ditch construction, and in particular to a construction device and a use method thereof that can meet the requirements of one-time slipform forming of highway drainage ditches of different shapes and sizes. Background Art

[0002] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention, and should not necessarily be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0003] Drainage ditches are usually set up on the outside of the slope foot of the roadbed on both sides of the road or on one side, and are the main components of highway ancillary facilities. According to the shape of the cross section, drainage ditches can be divided into different types such as trapezoidal, rectangular, triangular, etc., and their sizes are generally determined by hydrological and hydraulic calculations. On highways of all levels, drainage ditches can be used to clean up road surface water. Generally, the location where drainage ditches are set up is relatively low-lying, and the water will automatically flow to the drainage ditch. Then the accumulated water on the road surface will flow underground through the drainage ditch, and then the water from various sources within the roadbed and pavement will be diverted to the outside of the road boundary. In order to ensure that the highway drainage ditch has good functionality and durability, the drainage ditch usually needs to take certain measures to reinforce it. There are many types of reinforcement for highway drainage ditches, which are mainly determined by the soil quality of the drainage ditch, the longitudinal slope of the ditch bottom, the water flow speed and the use requirements.

[0004] At present, the construction of highway drainage ditches in my country usually adopts methods such as template casting concrete, prefabricated parts assembly construction and concrete slipform construction. The template casting construction method requires the use of fixed templates to support concrete manually. It is a casting method that includes multiple processes such as erecting, dismantling and pouring. This construction process is complicated, time-consuming and costly. The quality of drainage ditch construction mainly depends on the quality of template laying. It can be seen that template casting concrete construction will not only affect the construction quality of drainage ditches, but also affect the overall progress of the project. Prefabricated parts assembly construction requires workers to pre-cast prefabricated parts as required at a special construction site, and then transport the prefabricated parts to the construction site for assembly construction. This construction process requires the establishment of a special prefabrication plant. At the same time, leakage and other phenomena are prone to occur at the joints of each section of prefabricated parts, which will increase construction costs and affect construction quality.

[0005] In summary, the inventors found that the traditional highway drainage ditch construction process has the disadvantages of complex procedures, slow construction progress and high economic costs. Existing drainage ditch construction machinery cannot flexibly adjust the style and size of the drainage ditch. The style and size of the drainage ditch are single, and it is impossible to carry out construction of multiple demand combinations, which can no longer meet the requirements of high-quality construction of drainage ditches under complex working conditions.
