Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor found that when the slope is used for a long time, or there is a lot of rain for a long time, the slope is easily deformed due to its insufficient strength, causing the transport vehicles with earthwork or materials to pass by. The materials on the vehicle are easy to fall on the slope surface, which will affect the construction

Embodiment Construction

[0037] The following is attached Figure 1-2 The application is described in further detail.

[0038] The embodiment of the present application discloses a foundation pit trestle slope.

[0039] refer to figure 1 with figure 2 , a foundation pit trestle slope, comprising a trestle slab 1, a temporary hardened road 2, and a slope structure 3 arranged between the trestle slab 1 and the temporary hardened road 2. Among them, the slope structure 3 is used to support the transport vehicle for transferring materials on the temporary hardened road 2 .

[0040] The slope structure 3 includes the plain soil layer 31 at the bottom, the slope ballast 32 laid on the plain soil layer 31, and the slope surface layer 33 arranged on the slope ballast 32. Preferably, the slope ballast 32 is made of 500 mm Kind scum. The slope surface layer 33 includes a concrete layer 331 and a two-way steel bar structure 332 embedded in the concrete layer 331. The two-way steel bar structure 332 is form...

Abstract

The invention discloses a foundation pit trestle slope, and relates to the technical field of trestle construction, the foundation pit trestle slope comprises a trestle plate, a temporarily built hardened road and a slope structure, the slope structure comprises a plain soil layer located at the bottommost layer, slope ballast arranged on the plain soil layer and a slope surface layer arranged on the slope ballast, the slope surface layer comprises a concrete layer and a two-way steel bar structure embedded in the concrete layer, and the two-way steel bar structure is formed by vertically binding a plurality of steel bar bundles on a plane parallel to the slope surface layer. The invention further discloses a construction method of the foundation pit trestle slope. The construction method comprises the steps that 1, the horizontal distance and the vertical distance of the slope are measured; 2, a slope is excavated, and a slope structure is filled; 3, a vertical wall body is poured; 4, a drainage ditch is built; 5, a platform surface layer is built; and 6, the concrete retaining wall is poured. The bearing capacity, the supporting strength and the surface strength of the slope are improved, and the service life of the slope is prolonged.

Description

technical field [0001] The present application relates to the field of trestle construction, in particular to a foundation pit trestle slope and a construction method thereof. Background technique [0002] With the acceleration of urbanization and the dwindling of land resources, all kinds of urban buildings have begun to develop into underground space, which is manifested in the deepening of the foundation of buildings, especially in recent years. Ultra-deep foundation pit engineering with large area and complex plane shape. The foundation pit support scheme is an essential item in the foundation pit construction process. At present, reinforced concrete braces or corner braces are usually used as supports for deep foundation pit support, and reinforced concrete trestles are set up as earthwork and material transportation channels. [0003] At the same time, the trestle bridge is a passage connecting with the external temporary road. Since the foundation pits are set below ...
