Construction method for combining lattice beams with planting grooves on high soil slope

Abstract

The invention relates to a construction method for combining lattice beams with planting grooves on a high soil slope. The construction method comprises the following steps that the high soil slope is excavated step by step from top to bottom, meanwhile, slope supporting work is well conducted, and lattice beam grooving is conducted at designated positions; after the slope is excavated to the slope toe position, the planting grooves and a drainage ditch are excavated and constructed at the slope toe position; and lattice beam construction is conducted on the excavated high soil slope from bottom to top, longitudinal beam steel bars on the lattice beams extend to bottom plates of the planting grooves and are connected to steel bars in the planting grooves, and cross beams in the row of the bottommost parts of the lattice beams and the side edges of the planting grooves are integrally poured. According to the construction method, the planting grooves and the drainage ditch are constructed at the slope toe position of the excavated high soil slope firstly, then the lattice beams are constructed from bottom to top, the bottoms of the lattice beams are connected to the planting groove and the drainage ditch into a whole, it is guaranteed that the constructed lattice beams can effectively transmit force to the slope toe, the overall stress transmission of the lattice beams can be effectively improved, and moreover, the stability of the high soil slope is improved, the structure is simple, and the construction is convenient.

Description

technical field [0001] The invention relates to a construction method of frame beams combined with planting grooves on high soil quality slopes. Suitable for high soil slopes with sash beams. Background technique [0002] In engineering projects, soil slopes higher than 20m are generally called high slopes. If such slopes are not protected, they are prone to landslides and cause serious safety accidents. For the protection of high soil slopes, the most effective measures are often to reduce the slope ratio and implement deep drainage holes to ensure the stability of the slope. Anchor rods or anchor piles transmit the force to the entire slope, relying on the strength and stability of the soil itself to improve the stability of the overall slope. In addition, the hoop function of the frame beam effectively limits the soil arch effect of the high soil slope, further improving the stability of the slope.

AI Technical Summary

Problems solved by technology

[0003] In many existing engineering projects, the bottom of the sash beams is generally equipped with slope toe drainage ditches and planting grooves. Due to the influence of construction quality (such as the depth of the grooves does not meet the requirements) and weather factors (continuous torrential rain), the top of the sash beams prone to cracking and even slipping

In addition, the construction of sash beams is generally carried out from top to bottom. The bottom of the sash beams and the top of the planting grooves are often smoothed for aesthetics, and they are not connected effectively. During the construction process, the sash beams cannot transmit force. If the construction progress is slow, it will be extremely unfavorable to the stability of the slope
