Description

The lateral hard building enclosure of steel reinforcement cage for cast-in-situ bored pile
Technical field
The utility model is related to the technical field of steel reinforcement cage, the lateral hard of steel reinforcement cage of more particularly, to cast-in-situ bored pile Building enclosure.
Background technology
Bridges and culverts or Pile Foundation of Highrise Building construction in encounter solution cavity when, the prior art frequently with into hole throwing slabstone, The different construction technology such as slip casing by pressure and use steel pile casting follow-up.In the prior art, it when solution cavity is bigger, backfills to material Material demand is big, of high cost, and technical difficulty is high, quality problems easily occurs.
Utility model content
The purpose of this utility model is to provide the lateral hard building enclosures of steel reinforcement cage for cast-in-situ bored pile, it is intended to solve Certainly in the prior art, the problem of pile is of high cost, concrete easily leaks outside, easy mass accident.
The utility model is realized in this way the lateral hard building enclosure of steel reinforcement cage for cast-in-situ bored pile, including shape At in the solution cavity region of the periphery of stake holes medium position and steel reinforcement cage, the steel reinforcement cage is placed in the stake holes, the reinforcing bar The middle part of cage has the go along with sb. to guard him section opposite with the solution cavity region, and the periphery for going along with sb. to guard him section is enclosed with hard sleeve, described hard Section is gone along with sb. to guard him described in matter sleeve closure, and in the periphery arrangement of the prominent steel reinforcement cage, the hard sleeve is welded with the steel reinforcement cage It connects.
Further, the steel reinforcement cage includes multiple around the longitudinal rib being arranged in juxtaposition and around multiple longitudinal ribs Stirrup, the hard sleeve welds with the lengthways of rod and stirrup respectively.
Further, the length that the upper end of the hard sleeve enters the solution cavity area top soil body is 2 meters.
Further, the length that the lower end of the hard sleeve enters the solution cavity region lower part soil body is 2 meters.
Further, the hard sleeve is made of Steel material.
Further, the hard sleeve is welding fabrication.
Further, the hard sleeve is enclosed by multiple arcs steel plate.
Further, the periphery for going along with sb. to guard him section is enclosed with soft cloth set, and the soft cloth set extends respectively to hard set The top and lower part of pipe.
Compared with prior art, the lateral hard of the steel reinforcement cage provided by the utility model for cast-in-situ bored pile goes along with sb. to guard him knot The periphery closing for going along with sb. to guard him section of structure, steel reinforcement cage is enclosed with hard sleeve, after steel reinforcement cage is placed in stake holes, hard sleeve partition With the connection in solution cavity region inside steel reinforcement cage, when toward the inside casting concrete of steel reinforcement cage, concrete will not expand to solution cavity It dissipates, the cost of karst cave treatment will be saved, improve pile quality, avoid the occurrence of quality accident.
Description of the drawings
Fig. 1 is the schematic front view that hard sleeve is arranged on the steel reinforcement cage of the utility model embodiment offer;
Fig. 2 is cut-away illustration of the setting hard sleeve in utilization on the steel reinforcement cage of the utility model embodiment offer.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.
The realization of the utility model is described in detail below in conjunction with specific embodiment.
It is preferred embodiment provided by the utility model referring to Fig.1 shown in -2.
The lateral hard building enclosure of steel reinforcement cage provided in this embodiment for cast-in-situ bored pile, is used in bore forming In, be formed with solution cavity region 100, including steel reinforcement cage 12 on the outside of the medium position of stake holes, the middle part of steel reinforcement cage 12 have with it is molten What hole region 100 was aligned goes along with sb. to guard him section, is enclosed with hard sleeve 13 in the periphery for going along with sb. to guard him section of steel reinforcement cage 12,13 ring of hard sleeve It is arranged around the periphery for going along with sb. to guard him section of steel reinforcement cage 12, steel reinforcement cage 12 is gone along with sb. to guard him into section closing package, is welded with steel reinforcement cage 12, and hard Casing 13 is in the periphery arrangement of prominent steel reinforcement cage 12.
The lateral hard building enclosure of the steel reinforcement cage for cast-in-situ bored pile of above-mentioned offer, in practice of construction, steel reinforcement cage The 12 periphery closing for going along with sb. to guard him section is enclosed with hard sleeve 13, and after steel reinforcement cage 12 is placed in stake holes, hard sleeve 13 separates The connection of steel reinforcement cage 12 inside and solution cavity region 100, when toward the inside casting concrete of steel reinforcement cage 12, concrete will not be to Solution cavity is spread, and will save the cost of karst cave treatment, is improved pile quality, is avoided the occurrence of quality accident.
Specifically, steel reinforcement cage 12 includes multiple around the longitudinal rib 121 being arranged in juxtaposition and around multiple longitudinal ribs 121 Stirrup 122, above-mentioned hard sleeve 13 is welded with longitudinal reinforcement and stirrup 122 respectively, in this manner it is ensured that hard sleeve 13 exists Soundness on steel reinforcement cage 12.
