Excavation slope body structure and excavation construction method for rock slope

Abstract

The invention discloses a digging slope body structure used for a rock side slope and a digging construction method used for the digging slope body structure, and belongs to the technical field of civil engineering construction building. The invention provides the digging construction method of the digging slope body structure and the digging slope body structure with the advantages that the construction difficulty can be obviously reduced, and the construction work period can be effectively shortened. The digging slope body structure comprises packways with the width being not greater than 2m, a digging body with the vertical height not exceeding 15m, and a protection structure, fixedly arranged on the digging body slope surface through reinforcing structures, wherein the packways respectively arranged on the top surface and the bottom surface of the digging body are connected into a whole through the protection structure. The digging construction method comprises the following steps that a, parameters of the digging body are determined according to the construction work period requirements in accordance with the construction specification; b, the digging body is dug from top to bottom bench by bench according to the parameters; c, reinforcing structures and protection structures are constructed on the digging body through a construction scaffold; d, the construction scaffold is dismounted, and the construction is sequentially completed in the way.

Description

technical field [0001] The invention relates to an excavated slope body structure, in particular to an excavated slope body structure used for rock slopes, and belongs to the technical field of civil engineering construction. The invention also relates to an excavation construction method for the excavation slope structure. Background technique [0002] With the continuous deepening of my country's western development strategy, more and more new infrastructures have been built in the western region of my country. Many buildings, such as various dams, factories, switch stations, highways, etc., require large-scale construction due to site layout requirements. How to quickly complete the excavation and support construction of these slopes under the premise of ensuring the safety of the construction period has become an important technical problem faced by engineering construction in the western region. [0003] The current high and steep rock slopes generally determine the the...

AI Technical Summary

Problems solved by technology

[0016] 1. Since the construction scaffolding needs to be erected on the basis of the horse track, the height of the construction scaffolding reaches 30.0m, and the construction difficulty and safety risk are relatively large;

[0017] 2. The construction of the anchor bolts on the slope surface and the shotcrete with steel mesh hanging in the two schemes must lag behind the excavation surface of the slope by at least 37.5m, because the anchor bolts can only be constructed after the construction scaffolding is erected, and the erection of the construction scaffolding requires one below the horse road. The excavation of the ladder section can only be carried out, and the timeliness of slope support and protective measures is low. If the slope surface encounters fault exposure or broken rock belts, it will be difficult to guarantee the safety of the slope during the construction period;

[0018] 3. From the analysis of the construction period, no matter which construction method is adopted, the construction period is relatively long
