Construction method of cast-in-place drainage ditch

Abstract

The invention relates to a construction method of a pour-in-place drainage ditch. The construction method comprises the following steps of 1, selecting and assembling drainage ditch soil digging and cutting construction equipment; 2, digging a groove foundation pit by using a digging machine with a soil loosening device and a special-shaped digging bucket; 3, finishing a groove by using a drainageditch pouring construction equipment travelling system, arranging a drainage ditch sliding mold below an operation platform, and arranging a pouring funnel with a hydraulic system at the position, corresponding to a steel mold, above the operation platform; 4, pouring concrete; 5, vibrating the concrete; 6, striking off and plastering the drainage ditch by using a striking-off and collecting device; and 7, arranging an expansion joint and curing the concrete. The method has the beneficial effects that a soil loosening device of the drainage ditch soil digging and cutting construction equipment can be used for turning and loosening a pre-digging groove soil layer, the groove foundation pit can be easily dug with the cooperation of the special-shaped digging bucket, so that the soil diggingand cutting capability is enhanced, the groove can still be formed at one time under the construction condition of the hard soil and the frozen soil, the slope surface is smooth and flat, the slope top is straight and attractive, and manual finishing is not needed.

Description

technical field [0001] The invention relates to a cast-in-place drainage ditch, in particular to a construction method for a cast-in-situ drainage ditch. Background technique [0002] With the rapid development of our country and the increasingly developed road traffic network, the subgrade drainage system plays a key role in the normal use of traffic roads. Construction of subgrade drainage ditches is an indispensable link in road construction. At present, drainage ditch construction usually uses manual and mechanical excavation of the trench, and manual repair of the trench, which is prone to over-excavation and under-excavation, which is time-consuming and labor-intensive. The traditional formwork and slipform construction procedures of drainage ditches are cumbersome, the pouring efficiency is low, and vibration leakage is easy to cause concrete quality problems during vibration. Even though some new types of drainage ditch construction equipment have appeared and solv...

Problems solved by technology

At present, the drainage ditch construction usually uses manual and mechanical excavation of the trench, and manual repair of the trench, which is prone to over-excavation and under-excavation, which is time-consuming and labor-intensive.

The traditional formwork and slipform construction procedures of drainage ditches are cumbersome, the pouring efficiency is low, and vibration leakage is easy to cause concrete quality problems during vibration

Even though some new drainage ditch construction equipment has appeared and solved some problems, there are still insufficient cutting and digging capabilities of special-shaped bucket excavators in trenches, and the construction of drainage ditch pouring equipment still requires a lot of manual assistance, and the equipment is heavy and can Problems such as high consumption and low cost performance
