Abstract
The utility model discloses a shaft entrance anti-seepage device. Yellow mud is poured in all grooves leading to a shaft entrance, a closed cutoff wall is arranged between a shaft enclosure and a derrick foundation and stretches below the earth surface for 0.3-0.5m, and the height of the cutoff wall is consistent with that of backfilling gangue. Compared with the prior art, the shaft entrance anti-seepage device has the advantages that the yellow mud is poured in all the grooves leading to the shaft entrance, and therefore rainwater is effectively prevented from seeping the shaft through the grooves, before gangue backfilling, the closed cutoff wall is arranged between the shaft enclosure and the derrick foundation, external water can be prevented from entering positions close to the shaft entrance in a large range, and a double protection function is performed to prevent the water seepage of the shaft entrance. Therefore, the situations that the rainwater seeps the shaft, the clothes of staff get wet, or the rainwater enters materials are prevented, shaft equipment is protected, and normal using of the shaft equipment is guaranteed.
Description
Technical field
The utility model relates to protective device field, a kind of colliery, in particular a kind of pit shaft entrance anti-seepage device.
Background technology
The New Built Mine well head is reserved the gangue refill that utilizes excavation after finish on the basis, guarantees projecting zone, the surface plant face of land, guarantees during rainy season not poured into water in the pit shaft.But do not take in any anti-rainwater seeps water pit shaft from back production spoil slit.When rainwater, rainwater flows into the earth face of land along the slit of backfill spoil, the groove that is communicated with the pit shaft entrance on the earth face of land etc., flow in the pit shaft, shaft equipment is damaged, and freeze behind the shaft equipment trickle winter, thus the normal use of the shaft equipment of influence.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of rainwater that can effectively prevent to infiltrate the pit shaft entrance anti-seepage device in the pit shaft.
The utility model is achieved through the following technical solutions:
Pit shaft entrance anti-seepage device, in leading to the groove of pit shaft entrance, all fill yellow mud, be provided with closed together core wall between pit shaft enclosure wall and derrick footing, described core wall stretches into the following 0.3~0.5m in the face of land, and described core wall height is consistent with the height of backfill spoil.
Described core wall is reserved with the hole of cable laying or pipeline.
Described core wall is concrete or yellow mud core wall.
Described core wall is rectangle.
The utility model has the following advantages compared to existing technology:
The pit shaft entrance anti-seepage device that the utility model provides is filled yellow mud in all lead to the groove of pit shaft entrance, effectively stoped rainwater to infiltrate pit shaft in these grooves; And before the backfill spoil, between pit shaft enclosure wall and derrick footing, be provided with closed together core wall, can stop external water to enter near the pit shaft entrance on a large scale, played the effect of duplicate protection to preventing the infiltration of pit shaft entrance.Thereby prevented that rainwater from infiltrating pit shaft and drenching employee's clothes or enter stores van etc., protected shaft equipment, guaranteed the normal use of shaft equipment.
Description of drawings
Fig. 1 is plane structure schematic diagram of the present utility model.
Fig. 2 is the sectional drawing of core wall.
The specific embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Referring to Fig. 1, Fig. 2, lead at all in the grooves such as the cable trench 2 of pit shaft 1 entrance or water pipe groove 3 and fill yellow mud, in these grooves, infiltrate pit shaft 1 to prevent rainwater.Before backfill spoil 7, dirt bed 8 between pit shaft enclosure wall 4 and derrick footing 5 digs a wide about 1m, the degree of depth is to stretch into the groove of face of land earth 0.3~0.5m, rectangle of the closed formation of groove, build core wall 6 one at groove then, core wall 6 can be made with concrete or yellow mud, is reserved with the hole of cable laying or pipeline.During backfill spoil 7, note avoiding the destruction of 7 pairs of core walls 6 of backfill spoil near the pit shaft 1, prevent core wall 6 crackings.The height of core wall 6 is consistent with the height of backfill spoil 7.Core wall 6 can stop external water to enter near pit shaft 1 entrance on a large scale, has played the effect of duplicate protection to preventing the infiltration of pit shaft 1 entrance.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (4)
