Background

The selection of cast-in-place concrete curing materials is very important. The traditional health preserving materials are mainly straw curtains and the like, and have the defects of high manufacturing cost, easy decay and pollution. Geotextile is also called geotextile, is similar to geomembrane, is a water-permeable geosynthetic material formed by needling or weaving synthetic fibers, has the characteristics of no corrosion, no moth damage and no oxidation, has excellent filtering, water draining, isolating, reinforcing, seepage preventing and protecting functions, has light weight, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance, and is widely applied to the fields of engineering construction and the like, such as the construction of engineering of cast-in-place beams, expressways and the like. The geotextile is generally manufactured into specifications with the width of 4-6m and the length of 50-100m, and when the geotextile is used for a curing material of cast-in-place concrete, the geotextile is rolled up and stored after curing of one project/working surface, and can be reused when the next project/working surface is reached.

At present, the geotextile is widely applied to municipal engineering, house construction engineering and water supply and drainage engineering construction, but the inventor finds that the following problems exist in the process of maintaining the cast-in-place concrete covered by geotextile on the construction site at present:

① the manual paving covered by geotextile or the rolling speed after use is low, the paving efficiency is low, and the occupied construction time is long;

② when the geotextile is used for covering and manually paving or is rolled after use, the large-area concrete construction needs more manpower for paving operation, and the construction cost is increased;

③ the geotextile is used for covering the manual paving, the geotextile is easy to laterally move when the force is too strong in the construction process, the geotextile is not covered in place, and the construction quality is influenced;

④ adopts geotextile to cover the manual paving, and when facing the large-area concrete construction of the cast-in-place beam, the constructor needs to bend down to operate, which is hard and long in time and affects the health of the constructor.

In view of the above, in order to make the geotextile better applicable to building, municipal works, roads and other engineering projects involving concrete curing, the above problems in geotextile construction can be solved well, and technical improvements are necessary.
