Abstract

The invention discloses a gob-side entry retaining concrete partition wall construction mold bag and a construction method thereof. The mold bag is a bag with a closed structure; and the mold bag structurally comprises a fixed lug cylinder, a pouring exhaust hole, a mold bag top, a reinforcing rib, connecting feather eaves, an anchor bar hole and a concrete grouting duct. The construction method comprises the following steps of: penetrating a rigid beam into the fixed lug cylinder, jacking the rigid beam to a top plate by using a strut and fixing the rigid beam; penetrating a rope into a connecting hole of the connecting feather eaves to connect and position the adjacent mold bag; then penetrating an anchor bar and controlling a concrete pumping device; and finally, pumping concrete to fill the whole mold bag till the mold bag is full to the top. The mold bag is adaptive to the pouring of a gob-side entry retaining masonry partition wall of a coal mine, has a simple structure and high construction speed, and can be widely applied in quick masonry of the gob-side entry retaining partition wall of the mine and water conservancy, war industry and other civil engineering industries.

Description

technical field

[0001] The invention relates to a mold bag used for pouring concrete and a construction method thereof for a concrete partition wall, in particular to a concrete mold bag for pouring a gob-side entry partition wall and a construction method thereof. Background technique

[0002] Rigid formwork is commonly used for concrete pouring. Rigid formwork sometimes has severe grout leakage. Especially when laying bricks and stones and being positioned at the separating wall body between top and bottom plate, can't realize pouring on formwork top. If the pumping concrete technology is used in the rigid formwork, the joint grout leakage of the formwork will affect the compactness of the concrete filling. So there have been devices and application numbers such as application (patent) No. 200920034356.1 mining working face pouring concrete continuous wall along gob entry: 200910023718.1 mining working face device and method for pouring concrete continuous wall along gob...
