Embodiment 1

[0082] Such as figure 2 As shown, the adjacent well wall monomers 2 in this embodiment are overlapped with each other by annular steel belts 3 to form the whole well wall 1, or the part of one end of the well wall monomer 2 is processed to have a boss form, which can be used The boss is plugged and connected to the shaft wall as a whole 1 .

Embodiment 2

[0084] Such as image 3 As shown, in this embodiment, the adjacent well wall monomers 2 are overlapped by the annular steel belt 3 and the groove to form the whole well wall 1, or the well wall monomer 2 is processed into a second monomer with grooves and the first unit with the protruding part, the first unit and the second unit are plugged and connected. Specifically, the grooves and protrusions in this embodiment are both rectangular.

Embodiment 3

[0086] Such as Figure 4 As shown, in this embodiment, the adjacent well wall monomers 2 do not use overlapping joints, nor do they use plug-in connections, but only use connecting pieces to connect.

Abstract

The invention relates to the field of the mine construction, and discloses an assembled-type well lane construction method. The method comprises the following steps: performing a well lane excavatingand blasting cyclical footage horizontal test, and determining single cyclical footage; blasting rock; prefabricating multiple arc-shaped well lane single bodies, and fixing by using a fixing device;assembling the neighboring well lane single bodies as a well lane whole body through a connecting piece; and grouting and resisting water. The provided assembled-type well lane construction method iscapable of using the prefabricated well lane single bodies to be assembled as the well lane whole body through the connecting piece without performing in-site steel bar binding and concrete pouring work, and simplifying site construction working process, wherein the working process is simplified as follows: blasting; installing the well lane single bodies, constructing through the connecting piece; and grouting and resisting the water. The construction method is capable of reaching design strength while a shaft or a lane is installed, reducing work time, and improving a construction speed.

Description

technical field [0001] The invention relates to the field of mine construction, in particular to an assembly-type shaft construction method. Background technique [0002] At present, reinforced concrete is basically used as the shaft wall material for the support of shaft engineering, and steel mesh is generally bound, formwork is set up, and concrete is poured in construction. There are problems in the construction site that the amount of binding steel bars is large, the amount of supporting formwork, and pouring concrete are large, and the traditional Shaft wall construction technology, the initial strength of the shaft wall after pouring is weak, and the strength does not meet the design requirements. Under repeated explosion loads, cracks are prone to occur, which reduces the actual strength of the shaft wall and causes hidden dangers in engineering quality. [0003] Traditional roadway construction techniques generally include binding steel bars and shotcrete. After th...
