Problems solved by technology

[0006] The purpose of the present invention is to solve the technical problem that the traditional rolling type roadbed has many processes and will produce uneven and differential settlement, and provides a vertical pouring type solidified soil embankment construction mold and method, using vertical partitions for interval pouring of the roadbed The filling construction method can significantly shorten the construction period and adapt to the possible excessive deformation of the foundation. It is especially suitable for the rapid filling of emergency dams in water conservancy projects or the subgrade backfilling of bridgeheads and structures in traffic engineering.

Embodiment 1

[0044] Such as figure 1 , a construction mold for vertical pouring solidified soil embankment, comprising three longitudinal formworks and six transverse formworks, the three longitudinal formworks are arranged in parallel and at intervals, three transverse formworks are arranged at intervals between two adjacent longitudinal formworks, and three The vertical template and six horizontal templates are integrally enclosed to form a frame structure of matts.

[0045] Such as Figure 2-4 , the longitudinal formwork is PP plate, plastic geogrid is laid on both sides of the PP plate, grooves are separated on the longitudinal formwork, and a pair of sealing strips are fixed near the groove, and a pair of sealing strips are located on both sides of the groove. On the side, the distance between a pair of sealing strips is the thickness of the horizontal formwork, and a hook is hinged near each sealing strip on the longitudinal formwork. Located at the grooves at both ends of the long...

Embodiment 2

[0055] A construction method for vertical pouring solidified soil embankment, comprising:

[0056] Step 1. Transport the prepared formwork to the site, insert the formwork into the foundation according to the site conditions, and prepare the silt waste soil and inorganic curing agent required for the preparation of fluid filling;

[0057] Step 2: Preparation of fluid filler: Aiming at the initial water content of the silt waste soil (generally greater than 80%), adding an appropriate amount of cement or lime, so that the fluidity and self-compacting properties of the fluid solidification waste soil meet the design requirements.

[0058] Step 3. Before the pouring of the fluid filler, level and tamp the pouring area, release the embankment sideline, insert the longitudinal formwork with the sealing strip into the foundation soil manually, and press all the insertion strips at the lower end of the longitudinal formwork into the ground Stop pressing after the following, such as ...

Abstract

The invention discloses a vertical pouring type solidified soil embankment construction mold and method. The construction mold comprises a longitudinal formwork and a transverse formwork which are detachably connected, the longitudinal formwork and the transverse formwork are integrally enclosed to form a frame structure, and flow-state solidified soil is poured into the frame structure; and the longitudinal formwork and the transverse formwork are provided with through holes used for flowing of the flow-state solidified soil. According to the mold, each pouring area can be independently poured, free settlement is independently generated, the mold can well adapt to differential settlement caused by a foundation, and embankment tension fracture deformation caused by differential settlement is avoided. The embankment construction method provided by the invention has the advantages of few working procedures, short construction period, capability of greatly reducing the construction cost, no damage and waste of environment and resources by using the sludge waste soil as the filler, and capability of adapting to possible excessive deformation of the foundation, the construction method is particularly suitable for rapid filling of rescue dams in water conservancy projects or roadbed backfilling of bridge heads and structural road sections in traffic projects.

Description

technical field [0001] The invention relates to the technical field of roadbed filling construction, in particular to a construction mold and method for vertical pouring solidified soil embankment. Background technique [0002] By adding solidification materials to the silt waste soil, the water and clay minerals in the silt react physically and chemically with the solidification material, thereby improving the engineering properties of the silt, and the silt solidification soil formed by the treatment is used as a roadbed filler, which is the silt waste soil. An important way to recycle. [0003] Silt-solidified soil is used as roadbed filler to form a solidified soil roadbed. At present, it is mainly constructed by crushing and layered rolling, which is called a rolling-type solidified soil roadbed. First of all, it is necessary to dehydrate, solidify and stuff the silt waste soil with high moisture content to reduce its moisture content. However, according to the current...
