Abstract
The utility model relates to an improved drilling head used for pump suction reverse circulation. The improved drilling head is composed of a drilling bucket, alloy drilling teeth, a drilling teeth connecting rod, anti-falling barbs and a filter screen. The drilling bucket is composed of a circular steel bucket and a connecting fastener. The connecting fastener is disposed at the top end of the circular steel bucket and used for connecting the circular steel bucket with a drilling rod. The alloy drilling teeth are welded on the drilling teeth connecting rod which is welded at the bottom end of the circular steel bucket. The anti-falling barbs are composed of steel wire ropes and steel pipes, in which the steel wire ropes are arranged in a sleeving mode. The steel pipes are welded on the inner wall of the circular steel bucket. The filter screen is arranged at the top of the circular steel bucket. The improved drilling head used for pump suction reverse circulation has following beneficial effects: an improvement is made on a boulder stratum so that a problem that a pump is blocked by large blocks of boulders is effectively solved; and effective pore-forming of the boulder stratum is achieved.
Description
Technical field
The utility model belongs to building engineering field, particularly a kind of improved drill bit for erratic boulder stratum pump.
Background technology
For cobble and there is the stratum of erratic boulder, often adopt pump to inhale reverse circular technique construction.Pump is inhaled reverse circulation drilling hole construction method: in aperture, casing is set, and keeps certain head pressure, avoid collapse hole in drilling process.In drilling process, mud is from the bottom of ostium between drilling rod and hole wall, and the mud by slush pump at the bottom of by hole is extracted into mud pit from drilling rod center, and meanwhile, mud forms circulation in return aperture again.
The advantage that the pump adopting is at present inhaled reverse circular technique is: vibrate little, noise is low; Extension drill rod because digging brill, drill bit needn't dump up and down boring mud, as long as just can carry out deep layer brill and dig at every turn; Adopt special drill to bore and dig rock; Reverse circulation drilling pore-forming adopts rotary cutting mode, bores to dig by drill bit and rotates stably, and by native sand suction, the mud pressure in boring has been offset pore water pressure simultaneously, thereby avoids gushing the phenomenons such as sand; Can carry out over-water construction; Brill digs speed.
Although inhaling reverse circular technique, pump there is above-mentioned many merits, but in actual application, often there is serious plugging phenomenon, effectively pore-forming, particularly be difficult to bore dig the boulder bed larger than the mud suction mouth footpath of drill bit (generally more than 15cm), the normal phenomenon that stifled pump occurs, cannot normal construction, has greatly limited the range of application of reverse circular technique.
Summary of the invention
The purpose of this utility model is the deficiencies in the prior art, proposes a kind of pump and inhales the improvement drill bit of anti-circulation use, and this drill bit is the improvement of carrying out for special erratic boulder stratum, can effectively solve the problem of the stifled pump of bulk erratic boulder, can be at the effective pore-forming in erratic boulder stratum.
The improvement drill bit that a kind of pump described in the utility model is inhaled anti-circulation use is made up of drilling bucket, alloy brill tooth, brill tooth connecting rod, slip-off preventing hangnail and screen pack; Described drilling bucket by circular steel drum be connected securing member and form, described connection securing member is positioned at the top of circular steel drum, for connecting circular steel drum and drilling rod; Described alloy bores tooth and is welded on brill tooth connecting rod; Described brill tooth connecting rod is welded on circular steel drum bottom; Described slip-off preventing hangnail forms by wire rope and with steel pipe, on described wire rope, is socketed in steel pipe, and described steel-pipe welding is on circular inner walls of steel drums; Described screen pack is arranged on circular steel drum top.
Further, on described circular steel drum, a side sliding door is set, described side sliding door can be anchored on circular steel drum.
The length of described wire rope is less than the radius of circular steel drum.
A kind of pump described in the utility model is inhaled the improvement drill bit of anti-circulation use, its advantage is: utilize special drill described in the utility model to use after inverse circulation pump is inhaled in technique, can effectively solve that bulk floats is a difficult problem for stifled pump, can be at the effective pore-forming in erratic boulder stratum, through test, can suck the cobble that exceedes 30CM.Pump is inhaled and is instead circulated by feat of the powerful suction capactity of slush pump, and pore-forming efficiency is high, and the utilization of drill bit described in the utility model improves the range of application of having widened reverse circular technique.

Fig. 2 a kind of pump described in the utility model is inhaled the drilling pipe internal construction schematic diagram of the improvement drill bit of anti-circulation use;
In figure: 1, drilling rod; 2, side sliding door; 3, circular steel drum; 4, alloy bores tooth; 5, slip-off preventing hangnail; 6, bore tooth connecting rod; 7, screen pack 8, connection securing member.
The specific embodiment
As shown in Figure 1, the improvement drill bit that a kind of pump described in the utility model is inhaled anti-circulation use is bored tooth 4, is bored tooth connecting rod 6, slip-off preventing hangnail 5 and screen pack 7 and form by drilling bucket, alloy; Described drilling bucket by circular steel drum 3 be connected securing member 8 and form, described connection securing member 8 is positioned at the top of circular steel drum 3, for connecting circular steel drum 3 and drilling rod 1; Described alloy bores tooth 4 and is welded on brill tooth connecting rod 6; Described brill tooth connecting rod 6 is welded on circular steel drum 3 bottoms; Described slip-off preventing hangnail 5 forms by wire rope and with steel pipe, on described wire rope, is socketed in steel pipe, and described steel-pipe welding is on circular steel drum 3 inwalls; Described screen pack 7 is arranged on circular steel drum 3 tops.
One side sliding door 2 is set on described circular steel drum 3, and described side sliding door 2 can be anchored on circular steel drum 3.
Technical scheme described in the utility model is for the special circumstances that have erratic boulder piece, original drill bit is improved, drilling bucket can adopt the steel drum that 2 centimetres and above steel plate are made to form, drilling bucket diameter is depending on expanded diameter, drilling bucket top arranges a screen pack, the cobble of bulk is filtered in drilling bucket is logical, the grid of filter screen is laid and can be arranged with address exploration data according to scene is mad by force, grid adopts can select more than 5.0 reinforcing bar of common Φ, is welded in drilling bucket top and drilling rod connecting portion.
Go out welding wire rope hangnail for preventing that bulk cobble in drilling bucket from coming off at drill bit in addition, hangnail can adopt more than 10 wire rope of common Φ, puts on 10 centimeters of steel-pipe weldings and drill bit inwall, and drill bit bottom is according to the soft or hard degree on stratum, weld effective alloy and bore tooth, carry out broken formation.On drill bit sidewall, open a little sliding door, the size of effect sliding door is adjusted according to cobble particle size in stratum, in the time that the cobble in drill bit fills with, can be taken out from side door.
