Highway drainage ditch traction extrusion type slip form construction equipment and construction method

Abstract

The invention relates to highway drainage ditch traction extrusion type slip form construction equipment and a construction method. The equipment adopts winch traction and comprises a bearing framework, a guide device, a material storing and pumping device, a section adjusting device, a surface finishing device and the like. Through the guide device of the equipment, the equipment can be ensured to advance along the fixed axis direction of an adobe groove, and the construction of a drainage ditch with the groove width greatly different from the equipment width is realized; construction of drainage ditches with different section shapes and sizes can be completed by utilizing the section adjusting function of an equipment forming template; and by means of the surface finishing device of theequipment, automatic surface finishing operation is achieved after the drainage ditch slip form is formed. When traction extrusion type slip form construction is carried out on the drainage ditch, thereasonable range of the slump of the concrete is 10-45 mm, the vibration frequency range of the vibration rod is 30-60 Hz, the amplitude range of the vibration rod is 1.5-2.5 mm, the vibration time range of the concrete is 15-30 s, and the slip form speed range is 0.6-1.2 m / min. The construction equipment and the construction method have the characteristics of quickness, reliability and economical property, and have good popularization and application prospects.

Description

technical field [0001] The invention relates to the construction field of drainage ditches attached to highways, in particular to a construction device and a use method for forming highway drainage ditches of different shapes and sizes in one slip form. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Drainage channels are usually set on both sides of the road or outside the slope toe of one side of the roadbed, and are the main components of the road ancillary facilities. According to the shape of the cross section, the drainage ditch can be divided into different types such as trapezoidal, rectangular, and triangular, and its size is generally determined by hydrological ...

AI Technical Summary

Problems solved by technology

This kind of construction technology needs to set up a special prefabricated factory building, and at the same time, leakage and other phenomena are prone to occur at the joints of the prefabricated parts, which will increase the construction cost and affect the construction quality.

[0005] To sum up, the inventors found that the construction technology of traditional highway drainage ditches has the disadvantages of complex procedures, slow construction progress and high economic costs.

The 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 the construction of a combination of various needs. It can no longer meet the requirements of high-quality construction of the drainage ditch under complex working conditions.
