Abstract

The utility model provides a roof-contacted filling flow guide device, and belongs to the technical field of mining machinery by using a cemented filling mining method. The roof-contacted filling flow guide device comprises a flow guide tube which is placed above a layering channel. One end of the flow guide tube penetrates out of a filling baffle wall on the left side and is arranged at the highest position of a roof-contacted inlet way, and the other end of the flow guide tube penetrates out of a filling baffle wall on the right side and enters a flow guide inlet way. The flow guide tube is arranged obliquely. The roof-contacted filling flow guide device can effectively discharge slurry and water, release filling air pressure, and achieve complete roof contacting in underground roof-contacted filling. The roof-contacted filling flow guide device enables field operations to be simple in process and safe and reliable, and achieves safe and civilized production.

Description

A kind of filling connects the top guiding device

Technical field

The utility model belongs to the mining machinery technical field that adopts cemented filling method, and specifically a kind of filling connects the top guiding device.

Background technology

Connect when top in traditional filling, stay the osculum of a 300 * 300mm2 at filling board wall top.The effect one of osculum is spoil disposal slurry and water, the 2nd, and drainage filling air pressure.During near top board, mortar advances outward from the area head when obturation, and when arriving osculum, mortar just overflows from osculum.Build waterwall at route two ends, the mortar that will overflow concentrates in together, and after remaining water is drained, then clears up mud.Cleaning mud workload is large, time-consuming, and causes on-the-spot filthy.Because osculum place pressure is large, be easy to occur the osculum cracking, even the accident of a kind of rhyme scheme in Chinese operas serving as the prelude to a complete score for voices wall.Filling connect when top mud and water can not discharge fully, that causes the filling route not exclusively connects the top, brings serious potential safety hazard to safety in production.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of to connect the top in filling and the time can effectively discharge mud and water, drainage filling air pressure, reach the filling that connects the top fully and connect the top guiding device for shortcoming of the prior art.

Adopt following technical scheme for solving technical problem of the present utility model:

A kind of filling connects the top guiding device, comprise mozzle, described mozzle is placed in the top in layering road, and an end of described mozzle passes the left side filling counterfort and is arranged on the highest point that connects the jacking road, the other end passes the right side filling counterfort and enters the water conservancy diversion route, and described mozzle is obliquely installed.

Described mozzle tilts to hang fixing with iron wire or reinforcing bar.

Described mozzle is fixed to the highest point that connects the jacking road with anchor pole.

The utility model provides a kind of can effectively discharge mud and water, drainage filling air pressure when underground filling connects the top, reach the filling that connects the top fully connects the top guiding device, makes field operation technique simple, safe and reliable, accomplishes security civilization production.

Description of drawings

Fig. 1 is the utility model structural representation;

In figure, 1-filling pipe, 2-mozzle, 3-water conservancy diversion route, 4-connect the jacking road, 5-layering road, 6-filling counterfort.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described:

A kind of filling connects the top guiding device, comprise mozzle 2, mozzle 2 is placed in the top in layering road 3, mozzle 2 one ends is passed left side filling counterfort 6 use anchor poles be fixed to the highest point that connects jacking road 4, and the other end passes right side filling counterfort 6 by layering road 5 introducing water conservancy diversion routes 3.Mozzle 2 use iron wires or reinforcing bar are hung along certain gradient, prevent that mortar from overflowing rear formation adverse slope.

During use, obturation flows into through filling pipe 1 and connects jacking road 4, by mozzle 2, mud and water is entered water conservancy diversion route 3 by layering road 5 gravity flows when filling connects the top, reaches drainage filling air pressure, realizes connecing fully the purpose on top.The mozzle 2 that connects the top on jacking road 4 points to the direction of water conservancy diversion routes 3, and near the side of water conservancy diversion route 3.The mozzle 2 use iron wires in layering road 5 or reinforcing bar are hung fixing along certain gradient, prevent that mortar from overflowing rear formation adverse slope.Water conservancy diversion is pulled down mozzle 2 after finishing, and rinses well.

Claims (3)

1. a filling connects the top guiding device, it is characterized in that: comprise mozzle (2), described mozzle (2) is placed in the top in layering road (5), one end of described mozzle (2) passes left side filling counterfort (6) and is arranged on the highest point that connects jacking road (4), the other end passes right side filling counterfort (6) and enters water conservancy diversion route (3), and described mozzle (2) is obliquely installed.
2. a kind of filling according to claim 1 connects the top guiding device, it is characterized in that: described mozzle (2) tilts to hang fixing with iron wire or reinforcing bar.
3. a kind of filling according to claim 1 and 2 connects the top guiding device, it is characterized in that: described mozzle (2) is fixed to the highest point that connects jacking road (4) with anchor pole.
