A method of constructing underground garage by utilizing the bad situation of slope land

Abstract

The invention discloses a method for building underground garage by using poor situation of slope. The method comprises the following steps: (1) firstly planning the position of a planning area, planning a garage area according to the position of the planning area and reserving a later-period ramp area beside the garage area; (2) marking out an underground garage area and a frontage shop area in the garage area; (3) marking out an entrance area for entering the underground garage area and a step area through which people go in and out of the ground in a minimum-height part of the original natural floor of the place of the frontage shop area; (4) determining shop floor height of the frontage shop area, garage ground elevation and garage floor height of the underground garage area; (5) excavating the whole soil higher than the foundation elevation after the step (4) is completed, and then building the underground garage area and the frontage shop area; and (6) paving an insulation waterproof layer at the top of the garbage, backfilling the soil excavated in the step (5) and punning. Through the method, the topography is reasonably used; the building space is saved; the safety degree is high; the convenience is high.

Description

Technical field [0001] The invention relates to the field of construction, and in particular to a method for constructing an underground garage by using the poor status quo of slope land. Background technique [0002] With the development of urbanization and the improvement of people’s living standards, urban land has a certain degree of scarcity. However, the per capita ownership of cars is getting higher and higher, and it is difficult to build enough parking space, and the cost of parking spaces is also increasing. The higher the level, in the previously constructed office, commercial and living areas, the problem of large amounts of parking was not considered in the construction design, resulting in nowhere to park for later merchants or residents, and parked randomly in the community, beside the road or in the middle of the green belt. It brings great inconvenience to the lives of the surrounding people and occupies a lot of public land. In addition, a large number of motor...

Problems solved by technology

Among the technical schemes of parking garages built in the air, the most commonly used scheme is to build a combined garage, but this kind of garage is set on the ground and takes up more space on the ground. In the case of insufficient ground space, especially in cities in southern China , it is very inappropriate, and the garage affects the surrounding environment and the beauty of the community, and the investment in equipment is large; the more important problem is that the garage is built in the air, the stability is poor, it cannot be built high enough, and the foundation construction cannot be deep. Limited and poor practicability; in the construction of underground extended parking garage, due to its good utilization of underground space, underground garage has become a more practical garage construction direction

[0004] At present, there are mainly two conventional designs and methods for the construction of underground garages in the terrain with a slope of 2% to 8%. Among them, the conventional design method 1 is as follows: Figure 2~4 As shown, this method does not carry out large-scale filling and excavation of the site, and builds buildings according to the slope. The ground floor of the building is designed as a semi-basement or basement, and slope roads and steps are set between buildings to solve the problem of height difference, but This design method has certain disadvantages: 1. Parking in the site can only be located in the courtyard and on the first floor of the building at a low elevation; People and vehicles are not separated, and there are potential safety hazards; 3. The terrain of the site is lower than that of the adjacent site, and the accumulated water in the adjacent site will flow into the site, which is inconvenient for drainage; 4. The building is not as high as the adjacent site visually.

Conventional design method 2 such as Figure 5~6 As shown, this method performs large-scale filling of the site, builds retaining walls at low elevations, and uniformly trims the site elevation to the highest elevation position of the site. The first floor of the building can be used as general houses, garages or shops, etc., filling The site behind the square is flat, and there is no height difference in the road landscape. Building a ramp at the low elevation of the site to enter the site can solve the problem of vehicles and people entering and exiting, but this design method has certain disadvantages: 1. Parking in the site can only It is located in the courtyard and on the first floor of the building; 2. People and vehicles are not separated, and there are potential safety hazards; 3. Large-scale filling requires the purchase of earthwork, which needs to be transported from the outside to the site area, increasing the transportation volume and increasing the filling volume. quantity, increase the construction period, and high project cost
