As everyone knows, vast territory and abundant resources in China, the soil layer soil of carrying building is also ever-changing, especially be close to the hillside or have huge thick-layer to explode the zone of stone marine reclamation land with digging the mountain, it is being mingled with the bulk solid rock in soil layer, also have the pile foundation stake end of many engineerings need embed the basement rock certain depth, to increase bearing capacity and the uplift resistance of stake.How this class complexity or very dig out fast stake hole more than the diameter 600mm in the competent bed, be the engineering circles a difficult problem.
The technician people of the applicant unit one belongs to had once applied for the utility model patent of " a kind of dry type pneumatic rock drilling pile-driving machine and engineering method thereof " in 2009, the patent No. is ZL200910126569.1.This utility model is when construction rock drill hole pouring pile, and not only cutting rate is fast, and is dry type, environmental protection construction, and the job site is clean, mud-less pollution.Its job practices: by the auger stem bar chamber of the upper unit head drive of compressed air on pile frame, tap into again the down-hole hammer body, act on the down-the-hole tup that connects under the down-hole hammer body, compressed air turns Change and becomes per minute to impact the power of down-the-hole tup for 450-550 time in the hammer body, make the alloy tooth high-frequency on the tup impact ovum gravel or rock stratum, make it to pulverize.The tup diameter is less than the diameter 40-60mm of stake footpath with the steel casing.Lower unit head drives the steel casing, cobble or the severely-weathered rock stratum of digging out the 20-30mm width of remaining periphery by the aeratic hidden hole tup in the alloy dental drill head cutting stake hole of steel casing front end, after the down-the-hole tup enters middle weathered rock formation, lower unit head quits work, tup continue to cut a hole to the rock stratum into, enter design elevation.Then, the clamper of lower unit head lower end and steel casing are thrown off, and stay buried steel casing, remove pile frame to new stake position, and another steel casing of slinging carries out new pile hole construction.Steel casing on the former stake position then hangs in reinforcing cage by tracklaying crane, and pouring underwater concrete, and simultaneously, concrete placing limit, limit is hung high-frequency vibratory hammer by tracklaying crane and clamped the steel casing, exciting limit, limit pull steel protective-cylinder.Because steel casing bore is larger, length is longer, and soil layer, boulder bed are very large to the loading that the collateral resistance of steel casing adds the steel casing, and the tracklaying crane tonnage is joined by institute just to be needed very greatly, and price is very high, has improved construction cost.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of hydraulic pressure high frequency rotary vibration construction equipment that is applicable to dry type pneumatic rock drilling stake machine, to overcome the existing defective of above-mentioned dry type pneumatic rock drilling ram machine construction.
The technical scheme that the utility model adopts is: a kind of hydraulic pressure high frequency rotary vibration construction equipment (hereinafter to be referred as construction equipment) that is applicable to dry type pneumatic rock drilling stake machine, comprise and drive the steel casing rotating mechanism that the steel casing is done rotation rock drilling campaign, steel casing hold-fast body and hydraulic pressure dither mechanism, described steel casing rotating mechanism comprises the motor reducer drive unit and by the steel casing driving-disc of motor reducer drive unit driven rotary, described steel casing hold-fast body comprises oil cylinder and by the steel casing oil pressure pawl of hydraulic oil cylinder driving, and described hydraulic pressure dither mechanism comprises hydraulic motor and by the eccentric block of fluid motor-driven.
For further improving above-mentioned construction equipment running stability, preferred version is: described motor reducer drive unit is comprised of the motor that is symmetrical set, reducer and gear-box, described steel casing hold-fast body is comprised of the oil cylinder that is symmetrical set and steel casing oil pressure pawl, and described hydraulic pressure dither mechanism is comprised of the symmetrically arranged hydraulic motor in front and back and eccentric block.
The beneficial effects of the utility model: at existing this construction equipment of dry type pneumatic rock drilling pile-driving machine configuration, can realize that separate unit stake machine once finishes whole pile operations, comprise steel casing follow-up pore-forming, put into reinforcing cage, pouring underwater concrete in the steel casing, and the steel casing is extracted on exciting limit, limit, thereby finish a drill-pouring pile construction, do not need to dispose in addition tracklaying crane, thus reducing construction cost, and whole machine installation and working procedure are simple.
